Trading Fee Discount CalculatorHow much a referral code's fee discount could save you each month and each year

If, on top of sending money across borders, you also buy, sell, or swap on an exchange, fees add up to a real expense over time.

How to read this

Monthly fee before discount = monthly volume × fee rate. The more often and the larger you trade, the bigger this gets.
Saved after discount = original fee × discount rate. The discount usually applies to the fee itself; it is not cash handed to you.
The discount rate is not fixed, and it is not "forever"; it changes with exchange promotions and your tier, and the rate that applies to you shows on the fee page in your account once you have signed up.

For how to enter a referral code, how the discount works, and where to check your own rate after signing up, see the piece on opening an exchange account.

This is an estimate based on the assumptions you enter and is not a promise of returns. Trading itself carries risk, and fee rates, discount percentages, and promotion rules can all change, and everything is subject to the exchange's official page.

Where the number comes from

The arithmetic is deliberately plain: monthly volume × fee rate gives the monthly fee, and multiplying that by the discount rate gives what you would theoretically stop paying. No hidden parameters, nothing weighted; you can check it on a pocket calculator.

Of the two inputs, monthly volume is the one people inflate. Most enter what they intend to trade rather than what they actually traded. If you want a figure that means something, export a month of statements from the exchange and use the real total.

When the discount doesn't apply

A fee discount isn't universal across everything you might do on an exchange. Different product lines carry different fee rules; platform promotions can run their own separate arithmetic; and your account tier affects the base rate before any discount touches it. Those rules differ by platform and get revised, so nothing here is written as a fixed condition; the rate on the fee page in your own account is the one you actually pay.

Where to check your own rate after signing up is set out in the referral code guide.

This is not a return

What the tool calculates is fees you don't pay, which is a different thing from money you make. A fee saving changes nothing about whether a trade wins or loses, and crypto-asset prices move enough that what you lose there can dwarf anything saved here.

Worth stating plainly: trading more in order to save more on fees is a losing bargain. However good the discount, it only ever refunds part of a fee, while every additional trade carries the full market risk.

This calculator runs in your browser, and the numbers you enter are never uploaded. The fee rate you type in is most accurate when copied from the exchange's fee page. Updated 2026-09-08: added where the number comes from, when the discount doesn't apply, and why it is not a return.
