How to use it
- Fee rate: 0.1% is an editable calculation example, not a current-rate promise. Replace it with the figure shown on your account or the official fee page.
- BNB discount defaults to zero. Enter a percentage only if your account page currently shows one.
- Rebate/discount defaults to zero. Use what the sign-up or account page actually shows, not a percentage copied from an article.
To understand the logic behind these numbers, read how Binance fees are actually calculated; if you just want to know whether the BNB discount is worth it, read this one.
A worked example
For example, enter a 2000 USDT trade and a hypothetical 0.1% fee rate: the raw fee is 2 USDT. Leave both benefit inputs at their zero defaults and the net fee remains 2 USDT. Only enter a discount or rebate when your account or sign-up page explicitly shows that percentage. Results are estimates, not platform promises.
