Crypto Funding Rate Calculator
Calculate the total cost (or income) of holding perpetual futures positions over time based on the current funding rate.
Calculate Funding Costs
Enter your position size and funding rate to see how much you'll pay or receive for holding perpetual futures.
How to Use the Funding Rate Calculator
- Enter your position size — The total value of your perpetual futures position in USD. For example, if you hold 1 BTC at $50,000, enter 50,000.
- Input the current funding rate — This is typically displayed as a percentage on your exchange. Most show it as 0.01%, 0.05%, etc. Check your exchange's perpetual contract page for the current rate.
- Set the funding interval — Choose how often funding is paid. Most major exchanges use 8-hour intervals (3 times per day), but some like dYdX and Hyperliquid use 1-hour intervals.
- Select your time period — Choose whether you want to calculate costs for 1 day, 7 days, 30 days, or a custom period based on how long you plan to hold the position.
- Review your results — The calculator will show your total funding cost (or earnings if negative) for the selected period. Use this to factor funding into your trading decisions.
What Is the Funding Rate?
The funding rate is a periodic payment exchanged between long and short positions in perpetual futures markets. It serves as the primary mechanism that keeps the perpetual contract price anchored to the underlying spot price. Unlike traditional futures contracts that have a fixed expiry date and settle at predetermined times, perpetual futures contracts have no expiration — they can be held indefinitely.
This creates a unique challenge: without a settlement date to force convergence between the futures price and spot price, perpetual contracts could drift significantly away from the underlying asset's true value. The funding rate solves this problem by creating economic incentives that naturally pull the perpetual price back toward spot.
When the perpetual contract trades at a premium to spot (indicating bullish sentiment), the funding rate becomes positive, and traders holding long positions pay those holding shorts. Conversely, when the perpetual trades at a discount (bearish sentiment), the rate goes negative and shorts pay longs. This payment mechanism encourages arbitrage activity that helps maintain price alignment between perpetual and spot markets.
How Funding Payments Work
- Positive funding rate — Longs pay shorts. This happens when the perpetual price trades above spot, indicating bullish market sentiment. Traders are willing to pay a premium to maintain long exposure, so they compensate short sellers for providing that liquidity.
- Negative funding rate — Shorts pay longs. This occurs when the perpetual price trades below spot, indicating bearish sentiment. Short sellers are paying a premium for the ability to maintain bearish positions, so they compensate long holders.
- Payment frequency — Most major exchanges including Binance, Bybit, and OKX settle funding every 8 hours at 00:00, 08:00, and 16:00 UTC (3 times per day). Some exchanges like dYdX and Hyperliquid use 1-hour intervals for more granular price tracking. You only pay or receive funding if you hold a position at the exact settlement timestamp.
Funding Rate Formula
Funding Payment = Position Size × Funding Rate (%) Daily Cost = Funding Payment × Intervals Per Day Annual Funding Cost = Position Size × Funding Rate × Intervals Per Day × 365 Worked Example: You hold a $25,000 long position on a perpetual contract with a 0.01% funding rate, settled 3 times per day.
- Per-interval payment: $25,000 × 0.01% = $2.50
- Daily cost: $2.50 × 3 = $7.50
- Monthly cost (30 days): $7.50 × 30 = $225
- Annual cost: $7.50 × 365 = $2,737.50 (10.95% of position size)

Funding Rate Trading Strategies
Cash-and-Carry Arbitrage: This is a delta-neutral strategy that captures funding rate income with minimal directional risk. Here's how it works step-by-step:
- Identify a perpetual contract with a consistently positive funding rate (0.05% or higher is attractive)
- Simultaneously buy the underlying asset in the spot market and open an equal-sized short position on the perpetual contract
- Hold both positions through funding intervals to collect funding payments from long holders
- Your profit is the funding rate minus transaction fees and any basis risk from price divergence
- Close both positions when the funding rate normalizes or becomes negative
Funding Farming: This strategy involves taking positions specifically to be on the receiving end of funding payments during extreme market conditions. When funding rates spike to 0.1% or higher during high volatility, shorts can earn substantial income by providing liquidity to the market. However, this strategy carries significant risks: you're taking a directional position against the prevailing trend, which can result in losses that exceed funding income if the market continues moving against you. Proper risk management and stop losses are essential.
Cost-Aware Holding: For swing traders and position holders, monitoring funding rates is crucial to avoid unnecessary costs. If you're planning to hold a long position for several weeks during a bullish trend, you might face persistently positive funding rates that can eat into your profits. Consider these tactics: close positions before high-funding intervals and reopen after if you're actively monitoring, switch to spot holdings if you have the capital and don't need leverage, or factor the expected funding cost into your profit targets and stop losses to ensure your edge remains positive after costs.
How Funding Rates Affect Your P&L
Funding rates can have a substantial impact on your profitability, especially for longer-term positions. Let's examine a realistic scenario to understand the cumulative effect.
Example scenario: You hold a $50,000 long position for 30 days with an average funding rate of 0.02%, settled 3 times daily.
- Per interval: $50,000 × 0.02% = $10
- Daily accumulation: $10 × 3 intervals = $30/day
- Weekly accumulation: $30 × 7 = $210/week
- 30-day total: $30 × 30 = $900 (1.8% of position)
Comparison with different rate scenarios:
- Low rate (0.005%): $225 over 30 days (0.45% of position)
- Medium rate (0.01%): $450 over 30 days (0.9% of position)
- High rate (0.05%): $2,250 over 30 days (4.5% of position)
- Extreme rate (0.1%): $4,500 over 30 days (9% of position)
This demonstrates why funding rates matter: even in the low-rate scenario, you're giving up nearly half a percent of your position. In high-volatility periods with extreme rates, funding can eliminate your entire profit margin or turn a winning trade into a loss. Always factor funding costs into your position sizing and expected returns.
Frequently Asked Questions
What is a typical funding rate?
In neutral market conditions, funding rates typically range from 0.005% to 0.01% per 8-hour interval (approximately 0.015%-0.03% daily). During strong bullish trends or significant market events, rates can spike to 0.1% or higher per interval. Conversely, during extreme bearish sentiment or short squeezes, rates can go deeply negative, sometimes reaching -0.1% or lower. The average funding rate over longer periods tends to be slightly positive, reflecting a general bias toward long positions in crypto markets.
How often is funding paid?
Payment frequency varies by exchange. Most major platforms including Binance, Bybit, and OKX settle funding every 8 hours at 00:00, 08:00, and 16:00 UTC (3 times per day). Some exchanges like dYdX and Hyperliquid use 1-hour intervals for more frequent settlements. A few platforms use 4-hour intervals. You only pay or receive funding if you hold a position at the exact settlement timestamp. If you close your position even one second before settlement, you owe nothing. This creates opportunities for short-term traders to avoid funding costs entirely.
Can I earn money from funding rates?
Absolutely. If you're on the receiving side of the funding payment, you earn income. This means shorting perpetuals when the funding rate is positive, or going long when it's negative. Many professional traders use delta-neutral strategies (like cash-and-carry arbitrage) to capture funding income while hedging out directional price risk. During periods of extreme positive funding, shorts can earn annualized returns of 50-100% or more just from funding, though this requires taking bearish exposure during bullish market conditions.
Does funding rate change my liquidation price?
Yes, funding payments directly affect your margin balance. When you pay funding, it's deducted from your available margin, which effectively brings your liquidation price closer to the current market price. Over extended holding periods, accumulated funding costs can significantly erode your margin buffer. Conversely, if you're receiving funding, it's added to your margin, giving you more breathing room and pushing your liquidation price further away. Always monitor your margin ratio when holding leveraged positions long-term, especially during high-funding environments.
What causes funding rates to spike?
Funding rates spike when there's a significant imbalance between long and short interest in the perpetual market. The most common cause is strong directional momentum — during rapid bull runs, overwhelming demand for long positions pushes the perpetual price above spot, triggering high positive funding. Market events like major announcements, regulatory news, or macro developments can cause sudden shifts. Liquidation cascades can also create temporary spikes as one-sided liquidations force the perpetual price away from spot. High leverage usage amplifies these effects.
Should I avoid holding positions during high funding?
It depends on your trading strategy and conviction. If you're paying high funding (holding a long during positive funding spikes), you need to ensure your expected return exceeds the funding cost. For example, if funding is costing you 0.1% per 8 hours (0.3% daily), you need very strong conviction that the price will move significantly in your favor. Consider closing before funding intervals and reopening after, switching to spot if you don't need leverage, or accepting the cost if you believe the trend will continue. For short-term trades, high funding often signals overbought conditions and potential reversal opportunities.
