How to calculate crypto funding rate cost
It is a periodic payment between longs and shorts on a perpetual futures contract so the perpetual stays near the spot price. On most major venues it posts every 8 hours. When the rate is positive, longs pay shorts. When it is negative, shorts pay longs.
Funding paid per print is about trade size × the 8-hour rate. Multiply by how many prints you hold. Three prints is a day. Twenty-one is a week. A 0.01% rate on $10,000 is $1 per print, $3 a day, and about $1,095 a year if it never changed — roughly 11% annualized. Crowded longs get expensive even when the coin goes nowhere. Paste the rate from the exchange rather than trusting a stale widget. Subtract this cash flow from the futures calculator's net if you hold through several prints. Funding also moves equity, which can nudge you toward liquidation even if price is flat. The year figure assumes the rate never jumps, which it will.
Example
Funding rate example: $10,000 at 0.01% per 8 hours
Match this on the sliders: $10,000 position, 0.01% rate, 3 intervals for a day.
- Trade size
- $10,000
- 8h rate
- 0.01%
- Per print
- $1
- Per day
- $3
- If it never changed
- ~$1,095 / yr
- Who pays
- Longs, if +
That yearly number is a warning, not a forecast. The rate will jump. Paste today's print from the exchange, then drag the interval count for how long you actually plan to sit.
| Step | In words | Example |
|---|---|---|
| 1. Per print | Trade size × 8-hour rate | $10,000 × 0.01% = $1 |
| 2. Per day | Per print × prints in a day | $1 × 3 = $3 |
| 3. If it never changed | Per day × 365 | About $1,095 a year |
Limits
What this funding rate calculator cannot do
- It will not scrape the live rate from Binance or Bybit.
- It will not add price PnL. Use the futures calculator for that.
- It will not model a rate that jumps every print — you re-type it.
- It will not save a trade whose stop sits beyond liquidation.
If you already have a price target, run futures first, then subtract this bill if you held overnight.

Payment per 8-hour print is about trade size × the rate. Three prints is a day. Twenty-one is a week. A 0.01% rate on $10,000 is $1 per print, $3 a day.
On $10,000 that is $1 per print, $3 a day, about $1,095 a year if it never changed — roughly 11% annualized. That is a lot to pay for sitting still.
No. Paste the rate from the exchange. A stale widget on a website is how people undercount the bill.
Yes. Funding paid comes out of equity. That can nudge you toward liquidation even if price is flat. Re-check room after a string of prints.
Yes if you held through several prints. The futures calculator is price PnL. This page is the cash that moved while you waited.
No. It jumps when the perpetual trades rich or cheap versus spot. The year figure on this page is 'if it never changed,' which it will.
