Trading fee calculator
What one trade costs, what a round trip costs, and the percentage the price has to move before you have covered both sides.

spotHow the fee is worked out, and how current these rates are
How is the fee worked out?
Fee = order value × fee rate, charged separately on the entry and the exit, so a round trip costs roughly twice one side.
There is no cleverness in it. The only things that vary are the rate you qualify for and whether you were the maker or the taker on each side. The calculator applies one rate to both sides, which is the common case; if you place a resting limit order to open and then close with a market order, your two sides carry different rates and you would need to run the numbers twice.
Which rate applies to me?
The taker rate if your order executed immediately against something already on the book, and the maker rate if it rested there and someone else traded against it.
The distinction is about what your order did to the book, not what type of order you selected. A limit order priced aggressively enough to cross the spread executes immediately and pays the taker rate, which surprises people who assume limit orders are always maker orders. The write-up on maker and taker goes through this properly.
Is the BNB discount worth taking?
Arithmetically yes, but the absolute saving on a small account is measured in cents, and holding BNB to obtain it is itself an open position.
Set the order value to something realistic for your account and look at the "saved by the BNB discount" line. On a few thousand dollars of turnover the figure will not be exciting. That is the point of showing it: the discount is real, and it is not the thing standing between you and a profitable account.
The part that gets left out of most explanations is that you have to hold BNB for the discount to apply, and the value of that holding moves with the market. If you would not otherwise choose to hold it, the discount has bought you exposure you did not want. That is a trade-off worth making consciously rather than by default.
What does the break-even line mean?
It estimates the price move needed to cover fees by adding the selected fee rate for each leg. It assumes the same order value on both legs; the actual exit value changes with the price, so this is an approximation, not an exact break-even price.
At a 0.1% taker rate on both sides the number is small, and that is genuinely reassuring for anyone worried that spot fees are eating them alive. The reason it is worth displaying anyway is frequency: the break-even move is per trade, so a strategy that trades twenty times a week pays it twenty times. Fees do not kill a position, they kill a habit.
Note that this line only accounts for fees. It does not include the spread you cross, which for a market order in a thin book is often the larger cost, or slippage on size. The piece on market orders covers what that adds.
Futures fees are quoted on notional, so leverage multiplies them against your margin — this calculator is set up for spot. It also excludes funding on perpetuals, the spread on instant-convert products, and withdrawal fees. Those are all covered separately, and for a small account the withdrawal and the on-ramp are usually where the money actually goes.
How current are the built-in rates?
They were read off Binance’s own public fee schedule on 2026-08-30 and are hard-coded here as convenience presets, not fetched live.
Nothing on this page calls an API or reads a price feed. The tier options are typed-in constants, and they will drift out of date as the exchange changes its schedule. The "type my own rate" option exists for exactly that reason. The fee write-up has the tier table with a screenshot of the source, dated.
