Opening and closing
Count both sides of the position. Calculate against notional value, not just margin.

Know the full cost before you open a position.
Calculate entry and exit trading fees separately using the relevant position notional and fee rate. For perpetual contracts, add funding paid or subtract funding received. Apply rebates only to eligible trading fees.

Position cost worksheet
Opening fee. Closing fee. Funding.
Use your contract’s actual rates. Starting values are hypothetical examples, not OKX or Binance prices. Enter the signed funding rate shown by the exchange, then choose long or short so the calculator can determine whether you pay or receive.
Simplified linear-contract illustration: assumes unchanged notional, constant funding and rebate eligibility on both trading fees. Actual funding rates, timing and position value can change. Excludes price profit/loss, spread, slippage and liquidation charges. Funding is not rebated in this calculation.
Why margin is the wrong fee input
A position with $1,000 of margin and 10× leverage has approximately $10,000 of notional exposure. At a hypothetical 0.05% fee, one side costs $5, not $0.50. Closing the position can incur another fee. This explains costs; it is not a recommendation to use leverage.
Who pays funding?
At a positive funding rate, long positions pay short positions; a negative rate reverses the direction. OKX describes funding as a payment between position holders. Check the contract’s next settlement time: its interval can change. See OKX’s funding mechanism.
A worked example
For an unchanged $10,000 position, hypothetical opening and closing fees of 0.05% each total $10. An eligible 20% trading-fee rebate returns $2. One positive 0.01% funding period costs a long position $1, making its estimated net cost $9; a short receives $1, making its estimated net cost $7. These figures exclude price movements and execution costs.
What this worksheet leaves out
Actual entry, exit and funding values can differ as prices and position sizes change. Review each settlement in your account for a realized total. Coin-margined contracts require their own contract formula; this tool illustrates linear contracts. Binance’s futures fee guide explains its separate charge categories.

The answer
How do I calculate crypto futures fees and funding?

Funding over time
Keep periodic funding separate from exchange trading fees and rebate estimates.
Execution and risk

Before you decide
Questions traders ask.
Straight answers before you follow a referral link.
Are trading fees based on margin or position value?
For the linear contracts covered by this estimator, trading fees use the traded position notional. Inverse and other contract types need their own contract-specific calculations.
Can the funding result be negative?
Yes. This calculator uses a negative funding cost to mean funding received. It does not mean the position is profitable.
Are opening and closing fees always the same?
No. Execution type, rate and position value can differ between entry and exit. Check both sides.
Which exchange has the lowest futures fees?
Compare the same contract and execution assumptions using your actual account rates. Include funding and execution costs; this tool does not establish a market-wide cheapest exchange.
Is futures trading with zero fees really free?
A trading-fee promotion may exclude funding, spread, slippage or other charges. Read the product and promotion terms, including eligible pairs and expiry.
Are funding fees included in a trading-fee rebate?
Do not assume so. Treat funding separately unless the applicable offer explicitly includes it.
Which platform is cheapest for futures trading?
Compare the same contract, position size, maker or taker execution and holding period using the rates shown in your own account. This page does not rank every exchange.
Is an OKX rebate code the same as a referral or sign-up code?
On this page, FUTURESFEES is the OKX affiliate referral code associated with the eligible fee-rebate offer. People also call it a rebate code, invitation code or sign-up code. Check the code and benefit on OKX before completing registration.
Where do I enter the code after logging in?
If you already have an account, use the separate existing-user link in the OKX offer above. Log in and enter FUTURESFEES when prompted. The normal new-account registration link is a different route.
Can I add a referral code after signing up?
Use the existing-user linking route to check your account. An existing referral relationship may affect eligibility. Follow the result displayed by OKX; entering a code on this website does not change your exchange account.
Does a trading-fee rebate apply to my deposit?
No. The rebate is a share of eligible trading fees. It is not a percentage of your deposit, account balance or trading profit. Funding and other charges are separate unless the exchange offer explicitly includes them.
