Bitcoin funding fees are amounts exchanged between long and short users holding perpetual futures positions at the settlement time. The starting point for the general calculation is the position value at settlement × the funding rate for that interval, which differs from calculating the fee by multiplying the margin by the rate. You must check the payment direction, settlement interval, and settlement currency together to compare actual costs.
This article provides a practical explanation for Korean-speaking and global readers who want to understand funding fee calculations, funding fee payment times, the relationship with leverage, and the difference from fee discounts. Last checked: September 14, 2026. The prices, rates, and balances below are assumptions for calculation education and do not represent the current Bitcoin price, actual payment rates, or profit projections. Applicable conditions vary by product and place of residence for each exchange.
1. How Do Funding Fees Differ from Trading Fees?
Because perpetual futures have no expiration date, a mechanism is needed to reduce the divergence between the spot price and the contract price. Funding is one such mechanism. Unlike Maker and Taker fees incurred when an order is filled, funding fees depend on whether you hold a position subject to settlement for the relevant interval. Since longs and shorts are the two sides of a contract, a positive funding rate should not be simply interpreted as meaning that there are more long contracts than short contracts. The price premium and demand pressure must be examined separately.
| Category | Trading fees | Funding fees | Borrowing interest |
|---|---|---|---|
| Primary trigger | Order execution | Holding a position subject to settlement for a perpetual contract | Borrowing assets |
| Basis for comparison | Execution amount, Maker/Taker status, and account fee rate | Position value, rate, interval, and payment direction | Borrowed balance, time, and applicable interest rate |
| Can you receive it? | Standard fees are expenses; separate programs depend on their conditions | Possible depending on the position direction and sign | The borrower generally bears the interest |

2. Positive and Negative Funding Rates: Who Pays, Longs or Shorts?
| Settlement funding rate | Long position | Short position |
|---|---|---|
| Positive | Pays | Receives |
| Negative | Receives | Pays |
| 0% | Funding amount for the interval: 0 | Funding amount for the interval: 0 |
This is the standard payment direction for typical cryptocurrency perpetual contracts. The “estimated funding rate” shown on the screen may change before the next settlement, so do not calculate it as guaranteed income. Plus and minus signs for amounts in transaction histories may reflect deposit and withdrawal display conventions. Do not assume that the sign of the market funding rate is identical to the sign of the payment or receipt amount in your account.
3. How to Calculate Funding Fees: Direct Calculation in USDT
First, check the contract’s valuation method and settlement currency. The following is an example of a linear USDT perpetual contract in which the position value is calculated using the settlement reference price. If the product requires you to enter the number of contracts, you must reflect the quantity per contract and the multiplier; not all products on all exchanges use the same units.
Position value = BTC quantity held × settlement reference price
Absolute funding amount = position value × absolute funding rate
Assume that you hold 0.2 BTC, the settlement reference price is 100,000 USDT, and the funding rate for the relevant interval is +0.03%.
- Position value: 0.2 × 100,000 = 20,000 USDT
- Decimal conversion of the rate: 0.03% = 0.0003
- Funding amount: 20,000 × 0.0003 = 6 USDT
- If you are long, you pay 6 USDT; a short position of the same size generally receives 6 USDT.
The most common error is entering 0.03% as 0.03. This results in 600 USDT, which is 100 times larger than the correct calculation. When using a calculator, do not mix the method of pressing the “% button” with the method of entering the decimal divided by 100.
Why the amount calculated using the entry price differs from the actual records
Even for the same 0.2 BTC, if the settlement reference price is 105,000 USDT, the position value is 21,000 USDT, and at the same +0.03%, the amount is 6.3 USDT. You must check the value and price basis at the settlement time specified for the contract, rather than the value at entry. Actual differences may also arise from changes in quantity, decimal truncation, contract multipliers, and the settlement currency.
Coin-margined and inverse contracts use a different currency from the outset
Inverse contracts that convert a dollar-denominated notional value into BTC or another coin must not use the same numerical input method as linear contracts. For example, dividing a dollar notional value of 20,000 USD by a price of 100,000 USD gives 0.2 BTC, and applying 0.03% to this gives 0.00006 BTC. This is an assumption illustrating the structure, not a universal rule for all Coin-M products. Check the contract specification for the face value, multiplier, and valuation price, as well as the asset actually used for settlement.
4. Does increasing leverage also increase funding fees?
If the position value is the same, simply increasing the leverage number does not automatically multiply the funding amount. However, if the position is made larger with the same margin, the value used for the calculation increases, so the amount also increases. When comparing them, first determine whether the “position value is fixed” or the “margin is fixed.”
| Educational comparison | Margin assumption | Position value | One-time payment at +0.03% |
|---|---|---|---|
| Same position · 5x | 4,000 USDT | 20,000 USDT | 6 USDT |
| Same position · 10x | 2,000 USDT | 20,000 USDT | 6 USDT |
| Same margin · 5x | 2,000 USDT | 10,000 USDT | 3 USDT |
The margin in the table above is simplified as position value ÷ leverage, while trading costs, maintenance margin, and additional collateral are omitted. The funding amounts in the first two cases are the same, but the burden relative to the initial margin is 0.15% and 0.3%, respectively. The key point is that you assume the same price risk with less buffer capital; it does not mean that a higher multiple safely expands funding income.
5. Funding fee payment times: Distinguish UTC from Korean time
The premise that “all exchanges settle three times a day” may be incorrect. Settlement intervals may differ by trading pair, such as 1, 2, 4, or 8 hours, or may change depending on market conditions. The following table is an example of converting the times for an 8-hour contract that settles at 00:00, 08:00, and 16:00 UTC, not the current schedule for all contracts.
| UTC example | Korean KST (UTC+9) | UTC+8 region |
|---|---|---|
| 00:00 | 09:00 | 08:00 |
| 08:00 | 17:00 | 16:00 |
| 16:00 | 01:00 the following day | 00:00 the following day |
Readers outside Korea must check the local time zone and whether daylight saving time applies. Because some settlement cycles cross into the next date, record the exchange time zone as well when organizing transaction records. Even if you hold a position for only one hour, that cycle’s cost may apply if it is subject to settlement; do not arbitrarily calculate it pro rata by dividing the holding time by 8.
Entering just before settlement or closing just afterward to avoid costs is not guaranteed to work. Bybit advises of processing uncertainty during the seconds before and after settlement, while Binance and OKX also indicate differences in the actual processing time. The actual execution and settlement processing results matter, not the order submission time. Trading solely by targeting the moment the countdown reaches zero also increases the risks of slippage and non-execution.
6. How to compare funding rates with different intervals
If 0.01% and 0.02% appear on the screen, you cannot immediately conclude that the first is cheaper. They must be converted to the same period before comparison. The following calculation uses the strong assumptions that the position value is 20,000 USDT, the positive rate remains unchanged throughout the day, and the long position is held through every settlement.
| Assumed contract | Rate per cycle | Settlements per day | Simple daily rate | Daily payment |
|---|---|---|---|---|
| A: 8 hours | 0.03% | 3 | 0.09% | 18 USDT |
| B: 4 hours | 0.02% | 6 | 0.12% | 24 USDT |
| C: 1 hour | 0.01% | 24 | 0.24% | 48 USDT |
Although C has the lowest per-period rate, under this assumption it has the highest cumulative payout. However, because the rate, interval, and position value vary in actual trading, this table must not be used as an exchange ranking or as a forecast of tomorrow’s costs. A simple annualization of the expected rate is also not a definitive APR, deposit interest rate, or promised return.
Add each period separately when the rate changes
Assume that the confirmed rates for three periods on the same 20,000 USDT long position were +0.03%, −0.01%, and +0.02%, respectively. The amounts are 6 USDT paid, 2 USDT received, and 4 USDT paid, respectively. The net amount paid is 6 − 2 + 4 = 8 USDT. This differs from the estimate of 6 × 3 = 18 USDT based only on the first rate. If the quantity or price also changed, recalculate using the value at the time of each period.
7. Do fee discounts and referral benefits also apply to funding fees?
Trading fee discounts and reductions in funding fees must not be treated as the same benefit. You must review whether the discount applies to Maker or Taker execution fees, a separate rebate, or an event subsidy. A partner commission rate does not automatically become the user’s funding fee discount rate. Unless separate official terms explicitly state that funding is supported, do not reduce the funding fee by applying the standard trading fee discount rate.
For example, if the execution amounts for entry and exit are each 20,000 USDT and the assumed execution fee rate is 0.05%, the round-trip fee is 20 USDT. If a 20% discount applies only to that fee, it becomes 16 USDT. If the net funding fee paid is 8 USDT, the total is 16 + 8 = 24 USDT. Distinguish this from the incorrect calculation of (20 + 8) × 0.8 = 22.4 USDT. These figures are provided only to explain the scope of a discount and do not promise any specific CoinPop partnership benefit.
Slippage and price profit or loss are separate. If profit or loss has already been calculated using the actual execution price, organize the calculation so that the same slippage is not added again as a cost and deducted twice.
8. Is receiving funding fees a risk-free return?
No. In the example above, even if you receive 6 USDT, a 1% adverse price movement on a 20,000 USDT short position would result in a simple price loss of approximately 200 USDT. Looking only at a small funding receipt when deciding the position direction can cause you to overlook a much larger price risk. This comparison is also a simple calculation for a linear position and omits liquidation rules and execution costs.
Holding a spot position together with an opposite futures position does not eliminate the risk of a funding rate reversal, widening spot-futures price differences, only one side of the orders being filled, borrowing interest, exchange outages, insufficient collateral, or liquidation. If assets are divided across multiple platforms, transfer delays and counterparty risk must also be considered. Therefore, it is more accurate to make decisions based on total profit and loss and the risks that remain than on the expression “funding fee harvesting.”
9. When the balance has decreased but the transaction history is unclear
- Check the product. Determine whether it is spot, spot margin, perpetual, or dated futures, and which asset—USDT, USDC, or a coin—is used for settlement.
- Fix the applicable settlement period. Record the exchange’s time zone and the actual settlement time.
- Check the confirmed records instead of estimates. List the final rate, whether the amount was paid or received, and the quantity and valuation at the time side by side.
- Separate other costs. Check whether trading fees, borrowing interest, transfers, bonus clawbacks, or other items were mixed together on the same screen.
- Organize the basis for the discrepancy. Provide the contract name, settlement time, transaction history identifier, and calculation formula to official customer support, but do not share your password, OTP, or API key.
The order in which funding fees are deducted from the account balance or position margin varies by exchange and account mode. If collateral is affected, as in cases involving insufficient available balance on Bybit or the isolated and cross-margin deduction structures on OKX, liquidation risk may also change. Do not apply another exchange’s explanation directly to your own account; check the official rules for the relevant product.
10. Where to verify information in official exchange materials
- Bybit: Check the funding rate and countdown on the trading screen together with the Funding settlement records in UTA. The official explanation of funding fee calculations, deductions, and records provides the units for each product.
- Binance: Distinguish the real-time rate in the futures data from the Funding Rate History. The official funding rate guide explains the settlement targets and timing differences, as well as intervals that may change.
- OKX: Check the current interval, upper and lower limits, and countdown on the trading screen together with the contract specifications. The official perpetual funding fee mechanism distinguishes linear and coin-margined calculations and settlement by account mode.
- Bitget: First check the contract’s settlement currency and product structure. The official explanation of the unified account Coin-M and USDT-M structures helps compare the differences between dollar notional value and coin settlement.
These materials are sources for understanding the structure. The fact that you can read English-language help materials does not mean that the product is available in your country. Readers in Korea and elsewhere must separately verify usage restrictions in their place of residence, their account’s KYC and product eligibility, and the applicable terms. We do not recommend bypassing access restrictions or entering a false place of residence.
11. Frequently asked questions
Is the funding fee multiplied by the margin?
In the linear perpetual example in this article, it is multiplied by the notional position value. If you hold 20,000 USDT with 2,000 USDT in margin, the calculation basis is 20,000 USDT. The face value and multiplier per contract, as well as the settlement price rules, should be checked separately.
Does a short always receive the funding fee?
No. With a positive rate, the short generally receives the payment, but with a negative rate, the short pays it. The estimated rate for the next interval may change before it is finalized.
Why am I charged a cost even though I did not hold the position for eight hours?
This is because the applicable position may be determined based on whether the position exists at the settlement time, rather than by prorating the holding time. Check the actual product's interval and settlement details.
Is a high funding rate a signal that the price will fall?
It may provide information for examining the price premium or pressure from position demand, but it is not a standalone buy or sell signal. A high rate may persist or change direction, and the price trend and liquidity may also change along with it.
If trading fees are discounted, are funding fees reduced by the same rate?
You should not assume that. Execution fee discounts, partner commissions, and funding fee settlements are separate items. Only benefits confirmed under separate official terms should be reflected in the calculation.
Which should be used as the basis: the calculator's estimated amount or the actual payment amount?
The basis is the finalized account settlement history and the calculation rules for the relevant contract. The estimated amount merely assumes that the entered value, rate, and interval remain unchanged, and may not reflect changes in the settlement time or rounding.
12. Conclusion and Verification Method
CoinPop's conclusion is simple. Comparing funding fees is not about finding the lower number; it is about comparing payments and receipts using the same position value, the same period, and the same settlement currency. Before trading, check the product name, the rate for the relevant interval, the next settlement time, the valuation amount at that time, and the available collateral, then reconcile them against the finalized records after trading. Calculating fee discounts separately afterward can help reduce confusion.
