Funding Rate Calculator: Estimate Funding Payments and APR
A funding rate calculator estimates the payments exchanged between longs and shorts on a perpetual futures position. Enter your position size, the funding rate and its interval to see what you pay or earn.
- Per payment
- $1
- Per day
- $3
- Total over 90 payments
- $90
- APR
- 10.95%
How it is calculated
- Payment per interval = position size × funding rate
- Positive funding: longs pay shorts. Negative funding: shorts pay longs.
- Number of payments = holding hours ÷ funding interval
- APR = (funding rate ÷ interval hours) × 8,760
Frequently asked questions
- How do I calculate a funding fee?
- Multiply your position size (notional, not margin) by the funding rate. A $10,000 position at 0.01% pays or receives $1 per funding interval.
- Is funding charged on margin or position size?
- On position size (notional value). Leverage does not change the funding rate, but it makes funding larger relative to your margin.
