See what your exchange's trading fees and the spread cost per round trip and per year, the price move you need just to break even, and how much maker orders would save. Enter your own exchange's rates from its fee page: this page has no built-in exchange fees. Everything is calculated in your browser, and the numbers you type are never sent anywhere. Educational only, not financial advice.
Load example fills in made-up rates (0.2% maker, 0.4% taker, 0.2% spread on $1,000, 5 round trips a week), the same as in the fee guide. They are not any exchange's real fees; replace them with yours.
Enter your trade size and your exchange's maker and taker fees, then press Calculate.
Trading fees are a percentage of the position's value, charged on the entry and again on the exit. With leverage the position is your trade size × leverage, so fees take a bigger share of your margin. Your blended fee per side is maker share × maker fee + taker share × taker fee, and one round trip pays it twice. A taker order crosses half the spread on the way in and half on the way out, so an all-taker round trip pays the whole spread; resting maker fills are assumed not to pay it.
Break-even move is how far price has to move in your favour before the trade is ahead after costs: (2 × fee per side + spread paid) ÷ (1 − fee per side), for a long, with the exit fee charged on the exit value. Yearly cost is the cost per round trip × round trips a week × 52. Costs in R divide the round-trip cost by your risk per trade.
Two assumptions. 1) Maker fills are assumed not to pay the spread: only taker fills cross it. 2) The break-even move is for a long position (buy, then sell higher). A short's break-even is slightly different because the exit fee is charged on a lower exit value.
Not included: slippage on large or fast orders, funding on perpetual futures, fee discounts and withdrawal fees. Maker orders can go unfilled, so the savings assume they fill. For the full explanation and worked examples, read crypto trading fees explained.
