Before doing the math, remember one key rule: referral commission and BNB discount are two separate tracks. Referral commission is calculated first, and then the BNB discount is applied. They are not added together before applying a discount.

Let's start with referral commission. In the Binance wallet referral program, the inviter earns commission from the trading fees generated by invited users. The commission rate is based on the invited user's 30-day trading volume tier, ranging from 30% to 80%. This means if you are the invited user, you do not receive commission yourself — the commission goes to the inviter. The only benefit you receive as an invited user is a trading fee discount: a default 10% plus an extra 0%–20% allocated by the inviter, so your actual fee discount is between 10% and 30%.
Next, let's look at the BNB discount. When you use BNB to pay trading fees, spot and margin trading get a 25% discount, and futures trading gets a 10% discount. The calculation works like this: first calculate your original fee, then use BNB at market price to offset the discounted amount. It is not that BNB is deducted first and then referral commission is calculated, nor is referral commission calculated first and then BNB is deducted.
When these two benefits are stacked, the calculation order is "referral commission first, then BNB discount." Take spot trading as an example. Assume your original fee is 0.1%. As an invited user, you receive a 20% referral discount allocated by the inviter. On top of that, you still have the default 10% discount, so your actual discount may be even larger. First, the 0.1% becomes 0.08%. Then, if you also enable BNB payment, you pay 75% of that 0.08% (a 25% discount), giving a final effective fee rate of about 0.06%. The higher the referral rate and the bigger the BNB deduction, the more you save.

There is also an important change in 2026: starting from April 29, 2026, referral commission will change from being calculated on total fees to being calculated on net fees. This means only the amount after deducting market maker rebates will count toward the commission base. This change does not affect the calculation order described above, but it will make the final referral commission amount slightly smaller.
