## Direct Answer



> Perpetual futures funding is a periodic payment, typically every 8 hours, exchanged between long and short position holders to keep the perpetual contract's price anchored to spot. This calculator converts a funding rate into its daily cost, total cost over a chosen hold period, and annualized rate, so ongoing funding can be factored into expected profit and loss before entering a position.





      

# Perpetual Funding Rate Calculator



Perpetual futures typically charge or pay funding every 8 hours, though some exchanges and contracts use shorter intervals such as 4 hours or 1 hour. This calculator shows the daily cost, total cost over your hold period, and the annualized rate, so you can factor ongoing funding into expected P&L before entering a position.

## Funding Cost Calculator







Position size (USD notional)




Total notional value of your perp position, not margin posted.






Funding rate per 8-hour period (%)




Current rate shown on your exchange (e.g., 0.01 for 0.01%). Positive = longs pay shorts.






Hold period (days)




How many days you plan to hold the position.






Position side




Long (you pay when rate is positive)


Short (you receive when rate is positive)




Longs pay shorts when funding is positive; shorts pay longs when funding is negative.

### Results



Funding per 8-hour period



Daily funding cost (3 periods)



Total over hold period



Annualized funding rate



Breakeven price move needed



Results assume constant funding rate throughout the hold period. Actual rates change every 8 hours. Factor a 2-3x sensitivity check into your planning.












## How to Use This Calculator



1. **Position size:** Enter the total notional value (quantity × price), not the margin you posted. If you hold 1 BTC perp at $65,000, enter $65,000.
2. **Funding rate:** Find the current funding rate on your exchange's derivatives page (e.g., Binance Futures, Bybit, OKX). It is typically displayed as a percentage per 8-hour funding interval.
3. **Hold period:** Enter the number of days you intend to hold the position. For swing trades, 3-14 days is common; for longer directional holds, up to 30-90 days.
4. **Side:** Select Long or Short. When funding is positive, longs pay shorts, the calculator applies the correct sign automatically.
5. **Interpret results:** Compare "Total over hold period" to your expected profit from price movement. If funding represents more than 20-30% of expected profit, the trade may not have sufficient expected value to justify the position.
