Trading Fee Calculator

A fee is the service charge an exchange takes every time you buy or sell crypto. It looks tiny, usually about a tenth of a percent per trade, but it has two features that trip people up: it's charged as a percentage of the trade amount, so the bigger the amount the more it takes; and it's charged on every entry and exit, so for frequent traders the fees alone can eat a real chunk of principal over a year. So rather than chasing "zero fees," it's better to calculate them clearly and know where you stand.

What this calculator does

You enter the trade amount and fee rate, pick whether it's Maker or Taker, then decide whether to tick the BNB discount. When you hit calculate, it works out the fee locally in your browser as "trade amount × rate," and if the discount is ticked, multiplies the rate by 0.75 first. It also gives you the net amount (trade amount minus fee), the effective rate that applies, and how much the discount saved you. The whole thing runs offline and stores nothing.

Where Maker and Taker differ

In short: place a limit order that won't fill right away and wait for someone to trade against you, and you're the Maker, providing the market liquidity; eat into the existing orders on the book and fill immediately, and you're the Taker. Many exchanges charge Makers less, because they want to encourage resting orders. This tool doesn't split the two rates for you, since the numbers differ by account tier. You just enter the matching rate, and the Maker/Taker option is only there to label which kind this is.

How the BNB discount works

Binance lets you pay your spot fees with its platform token, BNB, and gives a discount in return, commonly 25% off, meaning the rate is multiplied by 0.75. To use it, you need a little BNB in your account and the toggle switched on in settings. This tool demonstrates it at ×0.75, but the actual discount and its scope can change at any time, so always go by what the exchange page shows at that moment. Don't treat the number here as a fixed rule.

What a beginner should remember most

• This calculates a one-way fee. Buying and selling are two trades, so the round-trip cost is counted twice.
• The more often you trade, the harder fees erode you. For a beginner, trading less and holding tighter often saves more than shaving the rate.
• Rates differ by trading pair and tier; the 0.1% here is just one common, public reference value.
• All rates and discount ratios change. This tool is an estimate, not a quote.
