How to use it
"Am I actually saving anything?" is the most common question after turning on the BNB discount or binding a referral code. The logic here is simple: use trade size × standard rate to work out "what you'd pay with no discount at all," then compare it with the fee actually deducted on your statement. If your paid amount is clearly lower than the standard figure, a discount is probably working; if the two are almost identical, it's worth going back to check your discount switch and referral binding.
This is only a rough reconciliation to point you in a direction. The real check is done line by line in your Binance trade history / statement: how much each trade was charged, whether it was paid in BNB, and whether anything was rebated. How to export and read the detail is in the article below.
This tool is an estimate and a qualitative read; the result depends on whether the rate you entered is the correct standard tier. Fees, discount ratios and rebates are all whatever your Binance account shows and may change with policy (checked June 2026). FeeFlux is an independent third party, not Binance official, and none of this is investment advice.
