Trading Fee Calculator

Estimate what a round trip costs, and how far price must move before you are back to flat.

When to use itWhen choosing an exchange, and before any strategy that trades small and often.

Copy the entry and exit fee rates from your exchange’s own fee page — market orders usually pay the higher (taker) rate.
Add the position value, plus funding or spread if you know them.
Read the break-even move. If it is a large share of the move you are aiming for, the trade mostly pays the exchange.

Result

Please correct the highlighted fields.

Formula

entry fee = notional × entry % ÷ 100
exit fee = notional × exit % ÷ 100
total = entry fee + exit fee + other costs
break-even move % = total ÷ notional × 100

Assumptions and limits

Assumes a single entry and a single exit. Scaling in or out multiplies the fee count.
Maker and taker rates usually differ; type the one that matches how you actually fill.
Funding on perpetuals accrues over time and is not a one-off — put an estimate in “other costs”.
Spread is a real cost even when it is not itemised on your statement.

Costs of a Round Trip

A complete trade charges you twice — spread and commission on entry and again on exit, plus whatever slippage the book hands you and any financing on a position held overnight. Price has to move a known distance before you are level.
