Crypto Funding Rate Calculator

Bottom line: use this crypto funding rate calculator to estimate what longs or shorts may pay at each perpetual futures funding event and what that rate means annualized. Funding can flip positive or negative, so verify the live contract before trading.

Quick answer

Bottom line: this calculator estimates perpetual funding cost or income over time. Use it to compare a trade before funding erosion changes the result.

Formula	Funding payment = position notional x funding rate x interval count.
Inputs	Notional, funding rate, interval count, position direction, and optional leverage.
Sources	Uses the rate you enter or an exchange snapshot where available, then applies the interval math in-browser.
Limits	Funding rates change quickly, and borrow costs or venue-specific rules can alter the real outcome.

How to Calculate Crypto Funding Rates

The Funding Rate Calculator helps perpetual futures traders estimate funding fees before holding a long or short position through the next funding event. In perpetual swaps, funding rates are periodic payments exchanged between long and short traders to keep the contract price close to spot.

For carry trades, the calculator can also estimate a delta-neutral spot-plus-perp scenario. That setup can reduce directional price exposure, but it is not risk-free because fees, slippage, exchange risk, margin requirements, and basis changes still matter.

Funding payout is calculated as: Funding Payment = Position Size × Funding Rate. Annualized APY: APY = Funding Rate × Funding Intervals Per Day × 365 × 100%. With leverage, the effective payout scales by: Effective Payout = Position Size × Leverage × Funding Rate. If the rate is positive, longs pay shorts; if negative, shorts pay longs.

Check for arbitrage opportunities by comparing with the exchange fee calculator, or use the Profit/Loss Calculator to monitor your net yields. For leverage risk management, try the liquidation price calculator.

Funding Fee Formula for Perpetual Futures

The basic estimate is Funding Payment = Position Notional x Funding Rate. If your position size is $20,000 and the funding rate is 0.01%, the estimated funding event is $2 before exchange-specific adjustments.

Annualized funding APY uses the interval count: Funding APY = Funding Rate x Events Per Day x 365. An 8-hour interval usually means 3 events per day.

Positive funding	Longs	Shorts
Negative funding	Shorts	Longs

Binance, Bybit and OKX Funding Rate Checks

Binance funding

Use the funding rate, symbol, interval, and notional from the Binance futures contract page before holding through the funding timestamp.

Bybit funding

Bybit perpetuals can use different contract settings by symbol. Confirm whether your side pays or receives before you scale leverage.

OKX funding

OKX funding estimates should be checked against the live instrument page because caps, intervals, and premium behavior can differ by contract.

Funding Rate Yield — FAQ

What is a crypto funding rate?

A crypto funding rate is a periodic payment between long and short traders in perpetual futures markets. It helps keep the perpetual contract price close to the underlying spot price.

Why am I paying funding fees?

You pay funding when your position is on the paying side of the current rate. When funding is positive, longs usually pay shorts. When funding is negative, shorts usually pay longs.

How often are funding rates paid?

Many major perpetual futures markets use an 8-hour funding interval, but the exact schedule depends on the exchange and contract. Some markets can use 4-hour or 1-hour intervals, so always check the current contract details.

How is the funding payment calculated?

Funding payment is estimated as position notional multiplied by the funding rate. For example, a $10,000 position at a 0.01% funding rate pays or receives about $1 at that funding event.

Can I use funding rates to make money?

Funding rates can be used in delta-neutral carry strategies, such as buying spot and shorting a perpetual contract. This can reduce price exposure, but it still has exchange risk, execution risk, borrow or margin risk, fees, and basis risk.

How do I annualize a crypto funding rate?

Annualized funding APY is estimated by multiplying the funding rate by the number of funding intervals per day and then by 365. For an 8-hour interval, there are usually three funding events per day.
