What is a funding rate calculator?
Perpetual contracts settle funding periodically (often every 8 hours): Funding = Notional × Funding Rate. Direction determines who pays whom.
This tool assumes a fixed rate. Rates change with the market; for longer holds use a historical average.
How to use
- Enter the notional (position) value.
- Enter the funding rate in percent (e.g. 0.01 = 0.01%) and the number of periods held.
- Click Calculate to see the single and cumulative funding cost.
Formula
- Single Funding = Notional × Funding Rate
- Total Funding = Single × Number of Periods
Example
Notional 10,000, rate 0.01%, 3 periods: single = 1, total = 3 USDT.
At 0.05%, the same position costs about 15 USDT over 3 periods — a key variable for long-term strategies.
FAQ
Do I always pay funding?
Not always. When the rate is positive, longs pay shorts; when negative, the opposite. This tool computes the absolute amount.
How often is funding settled?
Most major platforms settle every 8 hours, so one day is about 3 periods. Use your exchange's schedule.
