Latest updates, new calculators, and improvements to CryptoCalk.
Second Accuracy Check: 20 More Calculators Brought Up to Date
We went through twenty more calculators line by line and compared every figure with its source: exchange and protocol fee pages, the Ethereum consensus rules, US Treasury auctions and live network data. Most fixes are in the explanations and FAQs, but two calculators had calculation errors. The main changes:
Crypto card cashback: the Crypto.com preset counted a subscription rebate as 100% cashback (about $11,000 a year of "rewards"), and the 10-year value grew every year's rewards from day one, roughly doubling it. Both are fixed. Card terms are updated too: Coinbase One Card pays 2–4% in bitcoin and needs a paid membership, Fold pays 2%, and Gemini's 4% applies to the first $300 of spend a month.
Polymarket: Polymarket charges no fee on winnings; most markets have a small fee when you buy. A $0.65 share is −186 in US odds, not +54, and Polymarket now operates in the US through Polymarket US.
Validator nodes: Ethereum staking pays about 2.5–3% including MEV, not 4–7%. At $100 a month in running costs, a solo validator now earns less than staking through Lido. Since May 2025 a first slashing penalty is about 0.008 ETH, not 1 ETH, and Rocket Pool needs a 4 ETH bond.
"What if I had bought": today's prices were a May snapshot (Polkadot was 3.6× too high). They are refreshed to October 2026, the "1 year ago" and "6 months ago" presets now mean October 2025 and April 2026, and holding periods are counted to the month.
Mining, difficulty and energy: October 2026 network figures (difficulty ~133T, ~1,000 EH/s). One Antminer S21 needs about 29 years to mine 1 BTC, not 10, and the network uses roughly 175 TWh a year.
Gas, bridges and DeFi loans: costs now reflect October 2026 gas of about 0.1 Gwei: cents rather than dollars for most transactions. Ethereum blocks hold 60M gas, not 30M. In the loan example, liquidation comes after a 39% fall, not 17.5%.
Fees and benchmarks: Kraken Pro and Coinbase Advanced entry-tier fees are updated. The RWA calculator's Treasury-bill reference moves from 4.5% to 4.1%. Retirement, salary, rebalancing and Bitcoin Pizza Day examples now use BTC at about $83,600.
All figures are estimates dated October 2026 for general information, not financial or tax advice.
Compound Interest and NFT Profit Pages: Explanations Rewritten
Two calculator pages had long explanations that were written for a different tool. We replaced them with guidance for the calculator on the page:
Compound interest (crypto): the sections under the calculator were about leverage trading. They now explain how crypto yields compound: what the compounding frequency does to a quoted rate, monthly top-ups, and how much of the result is interest on interest. We also corrected the answer about daily versus monthly compounding: at 5–15% a year the difference is only about 0.01–0.1 percentage points, and about 10 points at 100%.
NFT profit: the English page's fee table now shows the fees the calculator actually uses (OpenSea 1%, Blur 0.5%, Magic Eden 2%, or any fee you type), notes OpenSea's rise from 0.5% to 1% in September 2025, and drops X2Y2, which closed in April 2025. The quick answer now includes the creator royalty. In our other five languages, the longer explanations were about NFT rarity scores; they now explain what a flip or a hold really nets after the marketplace fee, royalty and gas, and how to read the break-even price.
The calculations themselves did not change. Marketplace fees change often, so check the current fee on the listing screen before you sell. All figures are estimates for general information, not financial or tax advice.
The Explanations Further Down Each Page Now Match the Calculator Too
After fixing the "How to use" guides, we checked the longer explanations further down each calculator page the same way: how to read the results, scenarios to try, checklists, common mistakes and so on. On 86 calculators they still mentioned results, settings or live data the calculator does not have, or quoted figures the calculator would not actually show. We rewrote those passages in all six languages. Some examples:
Mining ROI: there is no resale value and no "mining versus buy-and-hold" result; the projection always runs 36 months from the revenue and expenses you enter.
Liquid staking: the protocol table keeps a fixed order at built-in reference rates. It does not re-rank by net yield or react to the rates you type.
What if I had bought: it looks back only. There is no future projection mode, no stock-market comparison and no annualized (CAGR) figure.
Whale alert: it estimates the impact of one trade you type in. It does not monitor transactions or give buy or sell signals.
Exchange fees: the comparison ranks 10 exchanges by the fee on a single trade. Withdrawal fees, spreads and yearly totals are not included.
Concentrated liquidity: the examples now match the calculator, about 39.5× capital efficiency on a ±5% range and 9.5× on ±20%.
We also repaired two broken links on Hindi pages. The calculations themselves did not change, only the text around them. All figures are estimates for general information, not financial or tax advice.
ASIC Mining Calculator: Litecoin Miners Now Include Dogecoin
Litecoin miners also earn Dogecoin for the same work through merged mining, and nearly every Litecoin pool pays it out. The ASIC calculator counted Litecoin only, so the Antminer L9 looked like a money-loser.
Antminer L9: with Dogecoin included it brings in about $8.50 a day instead of $1.40, which turns a loss of almost $5 a day at 8 cents per kWh into a profit of about $2.
Your choice: if your pool does not pay Dogecoin, pick "Only LTC" under Merged Mining. The comparison table follows the same setting.
ASIC Mining Calculator: The Explanation Now Matches the Tool
The text below the ASIC mining calculator promised features it does not have. It said the calculator shows your profit before and after the next Bitcoin halving, and it told you to enter network difficulty and a halved block reward. There are no such fields: difficulty, block reward and coin price load automatically from live network data, and the break-even estimate assumes they stay where they are today. The page now says so in all six languages and explains what to do instead.
Halving: for Bitcoin, the halving calculator shows your daily profit now and after the next halving side by side.
Lower prices or rising difficulty: income in the ASIC calculator rises and falls in step with hashrate, while electricity depends only on power. Enter half your hashrate with the same power to see what you would earn at half the coin price or half the block reward. About 75% of your hashrate approximates a year of 5% monthly difficulty growth.
Payback example: the text said an Antminer S21 Pro could pay for itself in about six months. At 6 cents per kWh with Bitcoin near $80,000 it takes more than three years, and at half that price it does not cover its electricity.
Smaller fixes: the page summary no longer promises an "ASIC value" figure the calculator does not produce, and the tip for checking your pool's payout now compares dollars, because the calculator shows income in dollars, not coins.
"How to Use" Guides Now Describe the Calculators You Actually See
Below every calculator there is a short guide: "How to use" and "What do the inputs mean?". We checked those guides against the calculators themselves, field by field. On 105 of our 128 calculators they described something the calculator does not have, such as an extra field, a switch, a live data feed or a result that never appears. We rewrote those passages in all six languages, so they now name only the fields you can fill in and the results you will see. A few examples:
Staking: the amount is entered in US dollars, not tokens, and there is no "price at end of period" field.
Tax calculator: it works out one sale at a time using your country's rates. It does not take a list of trades with dates, has no tax-rate fields and has no export.
Mining ROI: you type in your own monthly revenue and expenses. The calculator does not work revenue out from hashrate, and there is no resale value or buy-and-hold comparison.
Validator: there is no MEV-boost switch and no electricity field; include those in the yield and the monthly hardware cost.
Uniswap: the guide described a swap preview. The calculator actually estimates fee income and impermanent loss for a liquidity position.
Bitcoin ETF fees: all fourteen options are always compared side by side, and the default expected return is 12%, not 10%.
The calculations themselves did not change, only the explanations around them. All figures are estimates for general information, not financial or tax advice.
ASIC Mining Calculator: Zcash and Dash Miners Fixed
Two of the eleven miners in the ASIC calculator showed almost no income, so they looked like money-losers when they are not. Both now match what the network actually pays.
Antminer Z15 (Zcash): Zcash measures mining difficulty differently from Bitcoin, but the calculator used the Bitcoin formula for it. Income came out about half a million times too small, so all you saw was the electricity bill. The Z15 actually mines about 0.02 ZEC a day, roughly $24 at mid-October prices, which puts it at the top of the comparison table.
Antminer D9 (Dash): its speed was read in the wrong unit, a thousand times too slow. It is now 1,770 GH/s (1.77 TH/s) and brings in about $5.80 a day, close to its power bill at 8 cents per kWh.
Antminer L9 (Litecoin): now listed as 16 GH/s instead of 16,000 MH/s. That is the same speed in the unit Bitmain uses, so its results do not change. Efficiency is now shown in the right unit for each machine (J/TH, J/GH or J/KSol).
Mining Calculators: Live Network Data Is Back
The ASIC and GPU mining calculators load current difficulty, network hashrate, block rewards and coin prices again. The public relay they depended on had stopped working, so every visitor waited about 20 seconds and then got figures from May. The data now comes through our own server and is refreshed every ten minutes. If the feed is ever unreachable, the calculator tells you which date its backup figures are from instead of showing an error.
GPU mining backup figures: network hashrate for Ethereum Classic, Ergo and Kaspa had been entered roughly a thousand times too low, which made GPU mining look far more profitable than it is. An RTX 4090 on Ethereum Classic brings in a few cents a day before electricity, not the $57 the old figures implied.
Tax, Inheritance, Mining and ETF Pages: Outdated Figures Corrected
We re-read twenty pages line by line and checked every number against its official source. In several places the text below a calculator had fallen behind, even where the calculator itself was already right. Here is what changed:
Canada: the tax calculator now uses the 2026 federal brackets. The lowest federal rate fell from 15% to 14% in July 2025, so Canadian estimates come out slightly lower.
Country tax table: UK capital gains 18% / 24%, France 31.4%, Italy 33%, Brazil's progressive 15–22.5% (the proposed flat rate was rejected), South Korea's ₩2.5M deduction and the Netherlands' €59,357 threshold now match the calculator.
US inheritance: the federal estate tax exemption is $15 million for 2026 and the annual gift allowance is $19,000. Several answers still quoted 2024 figures.
Bitcoin halving: the price-after-halving table was wrong in five places. For example, eighteen months after the 2024 halving Bitcoin was about $110,000, not $84,000. Mining revenue on that page now uses today's network size (about 1,000 EH/s).
ASIC mining: the text overstated daily profit several times over. It now matches the calculator: an Antminer S21 Pro nets roughly $3–4 a day at 6 cents per kWh.
Bitcoin ETF fees: the "Self-custody saves you" figure always showed $0 because of a bug. That is fixed, and Grayscale's Bitcoin Mini Trust (0.15%) is now listed as the cheapest spot Bitcoin ETF.
Lightning: payments are now compared with a realistic on-chain fee (10 sat/vB) instead of 200 sat/vB, which exaggerated the savings.
Strategy (MicroStrategy) mNAV: the presets now reflect October 2026 (848,250 BTC, trading close to the value of its bitcoin) instead of late-2024 figures.
We also fixed a display problem on many calculator pages where links inside the explanations appeared as raw code. All figures are estimates for general information, not financial or tax advice.
Kaspa's October Reward Cut Applied, Mining Figures Refreshed
Kaspa lowers its mining reward a little every month instead of halving it every few years. The October step arrived on October 5: each block now pays 2.06017223 KAS, down from 2.18267645. We checked the new figure against the reward table built into Kaspa's own software and confirmed the network had actually passed the switch-over point before updating anything. Both the GPU mining calculator and the multi-coin mining switcher now use it.
While we were in the switcher, we re-measured all five coins against the live networks (difficulty and daily coin issuance, two sources each) and refreshed the prices. Two things changed that you would notice:
On an RTX 4090, Ergo and Ravencoin are now effectively tied, with Ergo ahead by less than one cent a day. On the RTX 3090, 3080 and 4080, Ravencoin still leads.
Bitcoin's price rise made the Antminer S21 noticeably better off. It now breaks even with electricity at about 9.6 cents per kWh, up from about 9 cents.
The questions and answers under the switcher were updated in all six languages to match. Kaspa's next step is due around November 4 (1.94454365 KAS per block). At 10 cents per kWh, nothing on the switcher page is profitable yet. All figures are estimates for general information, not financial or tax advice.
Mining Coin Switcher: Real Network Data Replaces Our Estimates, and the Ranking Changed Again
Earlier today we refreshed the coin prices in our multi-coin mining switcher. That fixed what the coins were worth, but it left something else untouched: how much of each coin your hardware actually earns per day. Those figures had been set by hand rather than measured, and when we finally checked them against the live networks they were off by anywhere from 1.4 times to roughly 500 times.
So the page was still recommending the wrong coin. We have now rebuilt those figures from the networks themselves — each chain's real difficulty and its real daily coin issuance, read from two independent sources apiece. Ravencoin is in fact the best coin for a graphics card, not Ergo, and it was previously ranked third.
The bigger finding is about Kaspa and Alephium. Both used to be graphics-card coins; both are now dominated by purpose-built mining machines. A single dedicated Kaspa miner does roughly twenty thousand times the work of a high-end graphics card, so a graphics card on those networks now earns well under a cent a day — not the near-tie our old figures suggested. They still appear on the page, because seeing how far behind they are is the useful answer to "should I point my card at Kaspa?"
We also fixed the hardware table. Some graphics-card speeds were labelled in the wrong units, and the Antminer KS5 was listed at 29 TH/s — a machine that does not exist. It is 20 TH/s.
Finally, we rewrote the questions and answers underneath the calculator in all six languages. They had been written separately from the calculator and contradicted both it and each other: the Portuguese version promised a graphics card would earn $1.50–$3.00 a day, the Spanish version $0.80–$2.50, and several still quoted Bitcoin at $60,000 when it is near $78,000. Every number there now comes from the same measurements as the calculator above it.
What it all adds up to: at 10 cents per kWh nothing on this page is profitable. A graphics card needs power at about 5 cents, an Antminer S21 about 9 cents, and a KS5 about 5.5 cents.
All figures are estimates for general information, not financial or tax advice.
Mining Coin Switcher: Flux Removed and Every Coin Price Refreshed
Our multi-coin mining switcher was still offering Flux (FLUX) as a coin you could mine with a graphics card. You cannot. Flux stopped using graphics cards entirely back in October 2025, when a network upgrade handed block production over to its own node operators. We removed Flux from our GPU mining calculator at the time, but this second calculator was missed — so it kept quoting a mining yield for a coin that no longer has any mining.
We re-checked before changing anything, and confirmed it three ways: the Flux software release notes, the project's own announcement, and the Flux blockchain itself, where each block now pays out purely to node operators with nothing going to a miner.
The same review turned up a bigger problem. Every coin price in this calculator was left over from late May 2026 and had never been refreshed. Prices had fallen a long way since — one coin, Alephium, was priced 34 times too high. Because the whole point of this page is to rank coins against each other, stale prices did not just make the numbers too big, they put the coins in the wrong order: the page recommended Kaspa and ranked Alephium second, when in fact Ergo ranks first and Alephium ranks last.
All prices are now refreshed and were each checked against two independent market sources. We also corrected Kaspa's yield for the four monthly reward reductions that had happened since May. The honest result is less cheerful than before: at 10 cents per kWh, no graphics card on this page currently covers its own electricity bill, so the ranking now shows which coin loses you the least. We rewrote the surrounding explanations, which had promised "clearly positive" returns, to match.
To make this harder to miss in future, the calculator now shows the date its prices were last refreshed, and we have added these values to the public register on our methodology page.
All figures are estimates for general information, not financial or tax advice.
Kaspa's Monthly Reward Step: Mining Estimates Updated to 2.18267645 KAS
Most coins cut their block reward in half every few years, and you can see it coming years out. Kaspa reduces its reward a little bit every single month instead — about 5.6% each time, a smooth glide rather than a cliff. The step scheduled for early September has happened, so our GPU mining calculator's fallback figure moved from 2.3125 to 2.18267645 KAS per block.
We read the new number straight from the Kaspa network's own API rather than from a mining-stats site, and checked it against Kaspa's published emission formula before applying it — it lands exactly on month 52 of the schedule, which is how we know it was a real scheduled step and not a bad reading.
In practice most visitors were already seeing a correct figure: the calculator pulls live network data whenever it can reach it, and this hardcoded value is the fallback for when it cannot. Because Kaspa drifts every month, that fallback goes slightly stale by design — so we refresh it on a monthly schedule. The next step is due around 5 October 2026.
All figures are estimates for general information, not financial or tax advice.
A Correction About Ads, and Every Calculator Now Shows Its Sources
First, a correction. Our homepage FAQ said this site works “without signup, payment, or ads”. The first two are true; the third was not — CryptoCalk carries display advertising, and always has. Our own editorial policy said so on the same site. The FAQ has been rewritten to match reality: free, no signup, no paywall, funded by display advertising, no affiliate links. We also corrected the page count we quoted about ourselves.
Second, and more usefully: 19 calculators that depend on tax law or protocol rules now show you where each number came from. Every tax rate, holding-period threshold, block reward and validator minimum is listed with the exact page it was read from and the date a human last checked it.
The methodology page now publishes the full table: all 17 tax jurisdictions we model, which document backs each one, and when it was last verified.
That table also marks the jurisdictions we have not yet traced back to the statute — where a value still rests on a tax-guide article rather than the law. Those are the ones we re-check next. It seemed more useful to show you the queue than to claim the job was finished.
Protocol facts are shown the same way: Bitcoin's block reward now points at the consensus code that defines it rather than at a third-party countdown site.
The profit calculator gained two diagrams — what a winning trade actually returns after fees, and how a long and a short mirror each other — and section headings across the site now ask the question you were probably searching for.
Each calculator's reading list is longer too. It used to be mostly US regulators; it now includes the Australian Tax Office, HMRC, the European and UK financial regulators, the OECD's crypto reporting standard, and the protocol specifications themselves.
All figures are estimates for general information, not financial or tax advice.
Per-Coin Guidance in the Profit Calculator, and a Fuller Account of Where Our Numbers Come From
The profit calculator now has a per-coin section. The arithmetic is the same for every asset, but the costs around it are not — and that is what quietly ruins a profit estimate.
Moving LINK or ANKR costs ETH, not the token itself, so an on-chain round trip on a cheap token can cost more than the trade earns.
Staked ATOM takes 21 days to unbond — your real exit price is the price three weeks after you decide to sell.
Staked ICP cannot be sold at all until its neuron dissolves.
For thin-liquidity meme coins like BONK, slippage usually costs more than the trading fee.
USDC and other dollar stablecoins have no price gain to calculate — set both prices to 1.00 and the calculator shows what the fees alone cost you.
We also expanded the pages that explain how this site works. The methodology now lists the actual primary source behind each tax and protocol figure — Portugal's from the Código do IRS, Germany's from the statutory texts, Canada's from the Income Tax Act, Japan's from the NTA, and Bitcoin's dust threshold from Bitcoin Core itself — plus how those 101 tracked values are re-checked on a schedule, the known limits of each model, and the mistakes we have found in our own numbers.
The about page and editorial policy now state plainly how the site is funded: display advertising only. No affiliate links, no referral parameters, no paid placements, and no advertiser input into any default value or result.
All figures are estimates for general information, not financial or tax advice.
Dash Mining Rewards Updated for the New Emission Era
Dash cuts its block reward by about 7.1% roughly every 383 days. The latest cut took effect on 16 August 2026, and our ASIC mining calculator now reflects it.
A miner's share per block has gone from 0.4426 DASH to 0.4109 DASH. We confirmed this by reading the actual reward payouts recorded on the Dash blockchain, rather than relying on third-party figures.
If you are estimating Dash mining returns, expect slightly lower daily coin output than before. The calculator uses live network data whenever it is available, so your estimates stay current either way.
The next reduction is expected around September 2027.
All figures are estimates for general information, not financial or tax advice.
Mining Rewards Corrected for Dash, Zcash & Ethereum Classic
Our mining calculators were crediting miners with coins that never reach them. Three fixes, all checked against the chains themselves:
Dash — a miner receives only 20% of each block; masternodes take 60% and the treasury 20%. We were using the whole in-block payout, which overstated Dash mining revenue roughly four-fold. Now corrected to the miner's actual share.
Zcash — 20% of each block goes to the development fund, so miners receive 1.25 ZEC, not the full 1.5625 block subsidy (a 25% overstatement).
Ethereum Classic — the block reward dropped 20% to 1.6384 ETC when era 6 began on 22 July 2026. We were still showing the previous era's 2.048.
Kaspa — refreshed to 2.3125 KAS from the network itself. Kaspa trims its reward a little every month, so this figure is a snapshot; the calculator uses live network data whenever it can reach it.
Also re-checked and confirmed unchanged: Portugal's crypto tax (28% under 365 days, exempt at 365+) and Avalanche's 2,000 AVAX validator minimum.
Heads-up: Dash reduces its reward again around 16 August 2026 — the calculators use live network data when available, so estimates follow along automatically.
All figures are estimates for general information, not financial or tax advice.
Japan Inheritance Tax — Now Follows the Official Method
A significant accuracy fix for anyone estimating Japanese inheritance tax:
The number of statutory heirs now matters. Japan's tax-free allowance is ¥30M plus ¥6M for each statutory heir, but the calculator previously always assumed a single heir. You can now enter the real number.
Tax is calculated Japan's way — the estate is split into statutory shares and each share is taxed separately using the National Tax Agency's official rate table, instead of applying one flat rate to the whole estate.
Together these corrections make a large difference: a ¥100M estate with three heirs previously showed roughly ¥19.2M of tax and now correctly shows ¥6.3M, matching the National Tax Agency's own worked example.
Japan's ¥200,000 crypto note was clarified — it applies to salaried employees, waives the filing requirement rather than the tax itself, and local inhabitant tax must still be declared.
All figures are estimates for general information, not financial or tax advice.
More Reliable Historical Prices
Behind-the-scenes reliability fix for our backtesting tools:
DCA Calculator and What If Calculator now pull deep historical prices from a more reliable free market-data source, so backtests for dates over a year old keep working.
Fixed a data-accuracy issue where a very old date (e.g. Bitcoin in 2013) could occasionally show a price from a later year instead of the actual historical price on that date.
All figures are estimates for general information, not financial or tax advice.
Smarter Search & Mining Data Accuracy
A few improvements to make CryptoCalk faster and more accurate:
Search now jumps straight to results — start typing a calculator name and matching tools scroll into view instantly, no more scrolling to find them.
Kaspa (KAS) mining reward corrected to its current per-block emission for accurate GPU mining estimates.
Flux (FLUX) removed from the GPU mining calculator — Flux moved to a node-based consensus in late 2025 and is no longer GPU-mineable.
UK capital gains note refreshed for the 2026/27 tax year.
All figures are estimates for general information, not financial or tax advice.
2026 Tax Rates & Mining Rewards Refreshed
We re-verified and updated the regulatory data behind the tax, inheritance, and mining calculators for 2026:
France flat tax (PFU) 30% → 31.4% and Italy crypto tax 26% → 33% (2026 budget laws)
US 2026 federal brackets refreshed; federal estate exemption raised to $15M (One Big Beautiful Bill)
Germany & Netherlands 2026 thresholds; Canada stays at 50% inclusion (the proposed 66.67% increase was cancelled)
Brazil reverted to progressive 15–22.5% (the 17.5% flat rate was rejected); South Korea deduction corrected to ₩2.5M; UK higher-rate CGT 24%
