Crypto Perpetual Futures: How Much Is the Funding Fee for Holding 600 USDT for 7 Days?
For a crypto perpetual futures position worth 600 USDT, if funding fees are settled every 8 hours over 7 days, the total funding fee is 1.26 USDT, assuming a funding rate of 0.01% at every settlement. However, actual costs vary depending on the exchange, cryptocurrency, funding rate at each settlement, and whether the position is long or short. You must first distinguish whether 600 USDT refers to margin or actual position value.
Funding Fee Calculation Formula for a 600 USDT Position
Funding fees for perpetual futures are calculated by multiplying the position value by the funding rate at the relevant settlement time. The same basic calculation method can be found in Binance's funding fee calculation guide and Bybit's official calculation guide.
Funding fee for settlement 1 = Position value × Funding rate
For example, if the position value is 600 USDT and the funding rate is +0.01%, the calculation is as follows.
600 × 0.0001 = 0.06 USDT
Therefore, at that settlement, the long position pays 0.06 USDT, while a short position under the same conditions receives 0.06 USDT. If the funding rate is negative, the payment direction is reversed.
Here, 0.01% is an assumption used for the calculation. It does not represent the current funding rate of any particular cryptocurrency or a rate that will remain unchanged over the next 7 days.
How Much Funding Fee Accumulates Over 7 Days?
Assume that funding is settled every 8 hours, the position value remains constant at 600 USDT, and a total of 21 settlements occur over 7 days. If the funding rate is identical at every settlement, multiply the fee for settlement 1 by 21 to calculate the total.
600 × Funding rate × 21
| Funding rate per settlement | Funding fee for 1 settlement | Cumulative funding fee for 21 settlements |
|---|---|---|
| 0.01% | 0.06 USDT | 1.26 USDT |
| 0.03% | 0.18 USDT | 3.78 USDT |
| 0.05% | 0.30 USDT | 6.30 USDT |
| 0.10% | 0.60 USDT | 12.60 USDT |
Author's calculation. This assumes a position value of 600 USDT, 21 settlements, and a constant funding rate at every settlement. It does not represent actual historical or future funding fees charged by an exchange.
The key point in this table is that even for the same 600 USDT position, the cost over 7 days can differ by a factor of 10 depending on whether the funding rate per settlement is 0.01% or 0.10%.
600 USDT in Margin Is Not the Same as 600 USDT in Position Value
If 600 USDT is the margin deposited into a futures account, the actual position value will vary according to leverage. Conversely, if the position value displayed on the trading screen is 600 USDT, you can use 600 USDT directly in the calculations in the table above.
For example, assume that a margin deposit of 600 USDT is used with 10× leverage, resulting in a position value of 6,000 USDT. If the funding rate is +0.01% at each settlement, the funding fee for 1 settlement is 0.60 USDT.
6,000 × 0.0001 × 21 = 12.60 USDT
This is a hypothetical calculation assuming that the position value remains constant and all 21 settlements use the same funding rate. The important distinction is that the funding rate is not multiplied by leverage itself; instead, it is applied to the actual position value after leverage has been taken into account.
How to Check the Actual Funding Fees Over 7 Days
To calculate the actual cost, check the following three items.
1. Exchange and trading pair: Identify the actual perpetual contract traded, such as BTCUSDT or ETHUSDT. Settlement intervals and funding rates may differ between trading pairs.
2. Funding rate at each settlement: Because the rate can change at every settlement, do not apply a single current rate to the entire 7-day period.
3. Position value and direction at settlement: You must hold the position at the settlement time to pay or receive the funding fee for that settlement.
Binance explains how to check real-time and historical funding rates in its official funding fee guide. Bybit also provides guidance on calculating funding fees and reviewing trading records.
Calculate the actual cumulative funding cost over 7 days as follows.
Cumulative funding fee = Sum of (position value × funding rate) at every settlement
Account for the payment direction for long and short positions. If the position value changes, the amount calculated at each settlement may also change.
Funding fees are also separate from trading fees. Entry and exit fees, profits and losses caused by price movements, slippage, and other costs are not included in the calculation above.
