If your futures trade opens with a maker fill and closes with a taker fill, calculate the entry and exit commissions separately, then add them. A round-trip estimate that applies one rate twice will be wrong whenever the two executions have different rates. The crypto fee calculator uses one selected order type for both sides, so use it as a comparison estimate and do the mixed-rate arithmetic separately when needed.
Calculate each execution on its own
For a linear contract quoted in the settlement currency, the basic commission estimate is:
fee for one execution = execution notional × fee rate ÷ 100
round-trip fees = entry fee + exit fee
Use the notional actually executed on each side. If you open $10,000 of exposure and later close the same quantity around a different price, the exit notional can differ from the entry notional. For a first-pass estimate with similar entry and exit notionals, you can write:
round-trip fees ≈ notional × (entry rate + exit rate) ÷ 100
“Maker” and “taker” describe how an execution interacts with the order book. An order that rests and adds liquidity can receive the maker classification; an order that immediately matches existing liquidity is a taker. An order type alone does not guarantee the classification: a limit order that fills immediately may be charged as taker. Binance explains both the notional-times-rate commission calculation and the maker/taker distinction in its futures fee explanation. Bybit also publishes maker and taker rates by product and account tier on its futures fee schedule.
Those pages describe venue-specific schedules and classifications. Your applicable rate can depend on contract, fee tier, region, promotions, discounts, and other conditions. Confirm the rate shown for your account and contract rather than treating an example rate as a promise.
Worked example: maker entry, taker exit
Assume a $10,000 entry notional, a $10,000 exit notional, a 0.02% maker entry rate, and a 0.05% taker exit rate. These are illustrative rates matching the calculator's current example table for selected regular-user perpetual products; they are not a universal or guaranteed schedule.
Entry:
$10,000 × 0.02 ÷ 100 = $2.00
Exit:
$10,000 × 0.05 ÷ 100 = $5.00
The estimated commission for both executions is $2.00 + $5.00 = $7.00. If both sides were charged at the maker rate, the estimate would instead be $4.00. If both sides were taker, it would be $10.00. With these assumed rates, applying the maker rate to both sides understates this mixed round trip by $3, while applying the taker rate to both sides overstates it by $3.
The fee total is not the same thing as the price movement required for break-even. For a one-unit linear position with equal entry and exit notional near $10,000, $7 in fees is roughly 0.07% of $10,000. The price move needed to cover that amount depends on quantity and the actual exit notional. If entry and exit notional differ, calculate each commission from its own execution rather than multiplying one notional by the rate sum.
Use the calculator to compare same-rate maker or taker scenarios across the exchanges it lists. Select the order type and round trip option, but remember that its inputs do not permit a maker rate for one side and a taker rate for the other. It also uses a fixed set of sample rates in its code; the exchange schedule can change. Treat its outputs as a quick comparison, then replace the sample rates with your applicable rates for a trade plan.
What the calculator includes and leaves out
The calculator computes notional × selected rate / 100. If round trip is selected, it doubles that single-side estimate. It then multiplies the per-trade estimate by trades per month and by twelve for its annual figure. For instance, a $10,000 notional at 0.05% is $5 per execution, or $10 for the calculator's same-rate round trip. Twenty such round trips are estimated at $200 per month and $2,400 per year, assuming the notional, rate, and number of trades remain constant.
It does not assign different entry and exit rates, estimate notional changes caused by price movement, determine whether a limit order actually added liquidity, or include funding, spread, slippage, taxes, or liquidation charges. It is a fee comparison for the rates encoded in the tool, not an account-connected fee audit. When your entry and exit executions differ, calculate them individually or use an average rate only if the approximation is acceptable for your purpose.
The commission is only one component of a perpetual trade's result. A favorable price move can be offset by entry and exit fees; funding may add or subtract another amount while the position is open. Use the futures PnL calculator to estimate a combined trade result from explicit assumptions, and the risk-reward calculator to examine a planned stop and target after costs. Keep the inputs consistent: the risk-reward result is only as useful as the fee assumptions supplied to it.
Common mistakes
- Doubling the maker fee when the exit is taker. Add the actual entry and exit fees rather than applying one rate twice.
- Assuming a limit order is always maker. A limit order that immediately matches may be taker. Classification depends on how it executes under the venue's rules.
- Using entry notional for every later fill. Closing notional can be different after a price move or a partial close.
- Entering a percentage as a decimal. A fee rate of 0.05% is entered in the formula as
0.05 ÷ 100, not as0.05(five percent). - Treating a sample fee table as your personal rate. Check the active contract and account fee schedule, including tier and discounts.
- Calling commissions the entire break-even cost. Funding, slippage, spread, and other charges may also affect the realized result.
- Multiplying by the leverage number. The commission calculation uses executed notional and fee rate. Leverage affects margin relative to notional, not this formula directly.
FAQ
Can the crypto fee calculator model maker entry and taker exit directly?
No. It applies the selected maker or taker rate to both sides when round trip is enabled. Calculate each side separately for a mixed-rate trade.
Is a market order always taker?
An order that executes immediately against resting orders is taker under the common order-book definition. Confirm the relevant exchange's treatment for the exact product and execution type.
Does the fee use leverage or margin?
The simplified calculation uses execution notional. A larger notional produces a larger fee at the same rate; leverage by itself is not multiplied into the fee.
Are funding payments included in the round-trip estimate?
No. Funding is a separate payment associated with holding a perpetual position through a funding event. Estimate it with the funding fee calculator and add it to your overall scenario if applicable.
How can I convert fees into a break-even move?
Divide total modeled fees by the position quantity to get the required price movement per unit for a linear contract, then account for both the entry and exit notionals and any other costs. It is an estimate, especially when fills are partial or prices move materially.
