Funding Rate Calculator
Scenario only, not a forecast: constant USD notional and funding rate, equal intervals and full holding days. No compounding, trading fees, slippage or liquidation modelling. Actual payments depend on the settlement timestamps crossed and the position value at each settlement. Verify the contract’s interval; the exchange button only sets a starting value.
Positive rates mean longs pay shorts; negative rates mean shorts pay longs. The selected rate applies to the full position value at each selected interval. Its sign alone does not establish a market direction or a profitable trade.

Compare the funding scenario with current rates
A fixed rate is a scenario. Compare funding across exchanges before evaluating the cost of holding a perpetual position.

Results depend on your inputs and the assumptions shown by this calculator. Reference links explain the model; they do not supply a live price feed. Fees, execution and changing market conditions can affect actual outcomes.
What is a funding payment?
Perpetual futures use recurring transfers between long and short positions to help align the contract with its underlying market. A positive rate makes longs pay shorts; a negative rate reverses the transfer. Funding is separate from the trading fees paid when opening or closing a position.
Enter the USD value of the entire position, not just your margin. With $10,000 notional and 10x leverage, initial margin is $1,000. At a rate of 0.01%, the payment magnitude is $1 per settlement regardless of that leverage. Leverage changes the burden relative to margin.
Worked example: 0.01% every eight hours
For a constant $10,000 position, a 0.01% rate gives $1 per interval. Three intervals per day give $3 per day and $21 over seven days. A long pays that amount; a short receives it. The $21 is 2.1% of the initial $1,000 margin at 10x leverage.
Changing the rate to −0.01% reverses the payer and recipient. This example holds notional and rate constant. Real prices and rates can change between settlements.
Payment = position notional × rate / 100 Intervals per day = 24 / interval hours Scenario total = payment × intervals per day × days
Which funding interval should I enter?
Use the rate and interval for the specific contract. Binance, Bybit and OKX can use different intervals across instruments or change them; eight hours is only a calculator preset. Hyperliquid settles hourly: enter the hourly rate rather than an eight-hour figure. This calculator does not fetch current rates or contract schedules.
A 0.01% eight-hour rate and a 0.01% hourly rate represent different costs. To compare the same constant-rate scenario, 0.01% per eight hours corresponds to 0.00125% per hour. At $10,000 notional, both produce $3 per day.
Daily rate = interval rate × 24 / interval hours
Annualized funding is not a promised return
Simple annualization scales the current scenario to 365 days. For 0.01% every eight hours, the magnitude is 10.95% per year. This is not compounding and does not forecast the next settlement or future rates. The calculator shows the magnitude; the pay/receive label identifies your cash-flow direction.
The equivalent price move divides the funding amount by position value. It measures the size of the funding cash flow, not a guaranteed exit price or full trade break-even. A receiving position does not need a favourable move to earn the transfer. Execution fees, slippage, borrowing costs and changes in position size still affect total profit.
Simple annualized rate = interval rate × 24 / interval hours × 365
Count settlements, not just elapsed hours
This tool projects full days. For an actual trade, count the settlement timestamps crossed while the position was eligible and sum each payment using its actual rate and position value. An eight-hour holding period can cross a different settlement count depending on entry, exit and venue rules.
Funding accrual is not automatically reinvested. A hedge can reduce directional exposure while leaving basis, execution, collateral and counterparty risks. Positive or negative funding alone cannot establish a reversal, a market top or a market bottom.
Does the funding fee use my margin or my position size?
Use the full position value for the selected contract. At $10,000 notional and a 0.01% rate, one payment is $1. Leverage changes the margin required, not that payment when notional is unchanged.
Are these live funding rates?
No. The rate, holding period and interval are scenario inputs. Check the selected contract on the exchange for its current funding rate, interval and next settlement time.
How do I compare hourly and eight-hour rates?
Put them on the same time basis. A constant 0.00125% hourly rate equals 0.01% per eight hours before fees and other changes. Do not compare the displayed percentages without their intervals.

Practise with worked lessons
- Calculate funding payments over your actual holding window
Build a settlement-by-settlement funding ledger from position notional and signed rates. Keep funding separate from margin, trading fees and price P&L.
- Compare hourly and eight-hour funding on equal terms
A 0.005% hourly rate costs twice as much as 0.02% every eight hours. Normalise funding to one horizon and keep snapshot APR apart from account returns.
- Funding forecast vs payment: explain the rate and exposure gap
A 30 USDT funding estimate became a 12 USDT receipt. Separate the rate change from the exposure change and reconcile the account's actual funding entry.
