Crypto Funding Rate Calculator
Calculate funding payments on a perpetual futures position over time.
Please note: Cryptocurrency is highly volatile and can lose value rapidly. All prices are entered manually — no live market data is used. Nothing here is investment advice.
What the Crypto Funding Rate Calculator does
Perpetual futures have no expiry, so exchanges use a periodic funding payment between longs and shorts to keep the contract price near spot. Held for long enough, funding can dwarf the trading fees.
Formula
Funding per interval = Position value × Funding rateLongs pay when the rate is positive; shorts pay when it is negativeAnnualised rate = Rate × (24 ÷ Hours per interval) × 365

Frequently asked questions
Can I earn from funding?
Yes. Taking the side that receives funding — often short in a strongly bullish market — earns the payment. Delta-neutral strategies hedge with spot to capture funding without price exposure.
How often is funding charged?
Most exchanges settle every 8 hours, giving three payments a day. Some use 1-hour or 4-hour intervals.
