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

Signing up with a referral code usually gets you a certain percentage off trading fees. Enter roughly how much you trade and estimate the savings. A local estimate only; no data is uploaded.

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, so always go by whatever the Binance sign-up / fee page shows at the time.
