How this calculator works
01
Enter the position side, notional value, signed funding rate, interval length, holding time, and round-trip fee rate.
02
CoinCalcs validates the manual inputs and applies this published model: Funding payment = position notional × rate per interval × interval count
03
The result is calculated locally in the browser and is not sent to CoinCalcs or a market-data provider.
Formula
The calculation
Funding payment = position notional × rate per interval × interval countExample
A concrete scenario

What this estimate cannot guarantee
- Future funding rates are unknown and can change sign or magnitude at every settlement interval.
- The result is only as current and accurate as the assumptions entered in the form.
- The output is educational scenario arithmetic, not financial, investment, tax, legal, or security advice.
