How to use GPU Mining Calculator
The GPU Mining Calculator estimates profitability for Ethereum Classic, Kaspa, Ravencoin, Ergo, and other GPU-mineable coins. Enter your GPU hashrate, power consumption, electricity rate, and pool fee to see daily, weekly, and monthly revenue and profit projections alongside a hardware payback period.
Use it to compare mining different coins with the same GPU setup — a 3080 Ti might earn more mining Kaspa than ETC depending on current difficulty and price. Run the calculator with today's coin price and a 20% lower price to ensure profitability holds up under moderate price decline. Factor in cooling overhead (typically 10–15% extra power consumption for enclosed rigs).
Input guide and assumptions
GPU hashrate must match the specific algorithm used by the target coin — your GPU may hash at 100 MH/s on Ethash but only 1.5 GH/s on KHeavyHash (Kaspa). Refer to benchmark databases like WhatToMine for algorithm-specific hashrates for your GPU model. Power consumption should include the full system draw, not just the GPU TDP.
Pool fee varies by pool — major pools like 2Miners, F2Pool, and Ethermine charge between 0.5% and 2%. The calculator auto-fills network difficulty and coin price from live data for the most popular GPU coins. For coins not listed, enter manual difficulty and block reward values from the coin's block explorer.
How to interpret results correctly
The GPU mining calculator outputs daily, monthly, and annual revenue and profit for your GPU setup, accounting for hashrate, power consumption, electricity cost, and pool fees. Unlike ASIC calculators, GPU mining profitability changes dramatically with the market — GPUs can switch between Ethereum Classic, Ravencoin, Ergo, and other algorithms. The calculator's "algorithm selector" allows profitability comparison across mineable coins for your specific GPU model.
The payback period (months to ROI) is the most important figure for GPU investment decisions. GPU hardware retains significant resale value (50–70% after 1 year vs. ASICs at 20–30%), which changes the break-even math. The "effective cost" for profitability analysis should be (GPU purchase price − estimated resale value after mining period), not the full purchase price.
Practical scenarios and planning workflow
GPU purchase decision: before buying a GPU for mining, enter the purchase price, expected hashrate for the target algorithm, power consumption, and your electricity rate. Compare the ROI period across 3–4 target coins. If the ROI period exceeds 12 months, the GPU must continue mining for over a year just to break even — a significant risk given market volatility.
Algorithm switching analysis: when a new coin's difficulty is low at launch, early mining captures above-average block rewards. Run this calculator for the new coin's current network parameters and compare profitability to your current algorithm. Factor in the switching overhead (software reconfiguration, rig instability risk) when evaluating whether to switch.
Risk and execution checklist
- Before starting GPU mining: 1) Confirm your electricity rate — GPU mining is extremely electricity-sensitive — use our <a href="/electricity-cost-calculator/">electricity cost calculator</a> to get exact numbers; a 10% rate difference can swing profitability from positive to negative. 2) Measure actual GPU power draw at wall (not spec sheet TDP), since mining power draw can be 20–30% higher than gaming draw. 3) Calculate cooling overhead cost — GPUs run hot; increased AC cost should be included.
- After calculating: compare to the alternative of simply buying and holding the coin you would have mined. At equal electricity cost per coin, buying is simpler; mining only adds value if you have cheap electricity or undervalued hardware.
Common mistakes to avoid
- Using the GPU manufacturer's TDP spec for power consumption. Mining-optimized GPUs push hardware harder than spec. Measure actual wall draw using a kill-a-watt meter — the true figure can be 15–30% higher than spec, significantly impacting electricity cost projections.
- Mining a single coin regardless of profitability changes. Algorithm switching rigs can be 20–40% more profitable annually by following profitability signals. Use this calculator weekly and compare the top 3–5 algorithms for your GPU to identify switching opportunities.
Performance benchmarks and expectation ranges
GPU mining profitability benchmarks (2026): high-end gaming GPUs (RTX 4090, RX 7900 XTX) at $0.05/kWh produce $3–8/day mining Ethereum Classic or Kaspa. At $0.10/kWh, profitability halves. At $0.15/kWh, most GPUs mine at a loss at current difficulty levels.
Capital efficiency comparison: a GPU rig costing $5,000 producing $5/day = 1000-day payback (2.7 years). At $3/day, payback is 1667 days (4.6 years). For profitable GPU mining in 2026 and beyond, electricity below $0.06/kWh is the practical requirement.
Execution templates you can reuse
GPU mining setup workflow: 1) Benchmark GPU hashrate using dedicated mining software (not manufacturer specs). 2) Measure wall power draw at 100% mining load. 3) Enter values into this calculator for your target coin. 4) Compare net daily profit to alternative uses of the GPU (gaming PC rental, AI inference). 5) Deploy if <a href="/roi-calculator/">ROI</a> < 12 months at current prices.
Profitability maintenance: check the calculator weekly and compare current mining coin to top alternatives. Use nicehash profitability estimator or WhatToMine as cross-references. Switching algorithms costs 5–15 minutes of downtime — factor this in only if the profitability gain exceeds the switch overhead cost.
Data hygiene and model maintenance
Monitor GPU temperatures during extended mining runs — sustained operation above 85°C (junction temp) degrades VRAM and GPU lifespan. Optimize fan curves and consider undervolting (reduce power by 15–20% while maintaining 95%+ hashrate) to extend hardware life and reduce electricity cost simultaneously.
Log your actual earnings from pool dashboard weekly and compare to the calculator's prediction. Consistent underperformance (>10%) suggests network difficulty increased faster than modeled, or pool efficiency/orphan rate is higher than assumed. Update calculator inputs with actual pool earnings for better forecasting.
Final validation before capital deployment
Verify daily coin output: (hashrate / network hashrate) × block reward × blocks per day = daily coin output. Compare to pool dashboard — pool efficiency should be 98–99.5% of theoretical. Significant underperformance indicates high orphan rate or pool inefficiency.
Validate electricity cost: (GPU wattage / 1000) × 24 × electricity rate = daily electricity cost. For a 300W GPU at $0.10/kWh: 0.3 × 24 × $0.10 = $0.72/day. Verify this matches the calculator's electricity cost output.
