In Binance trading, fees are a fixed expense that directly affects long-term returns
By binding the invitation code and applying cumulative discounts, the maximum fee reduction in the first month can reach 45% (invitation code discount + BNB deduction)
Spot trading
Spot trading fee rate

The default unilateral fee rate for spot trading is 0.1%
Basic rebate discount: fees can enjoy a permanent 20%
Cumulative discount: enabling BNB deduction allows for a 25% deduction in spot trading
The maximum fee reduction for spot trading can reach 45%
Example:
User purchases 10,000 USDT of Bitcoin spot
Fee is 10000×0.1%=10
After applying the discounts, the actual fee expenditure is 5.5
Contract trading

The default unilateral fee rate for contract trading is 0.02% (limit order) 0.05% (taking the order)
Example:
User trades 100,000 USDT of Bitcoin contracts with 10x leverage (taking the order)
Unilateral fee is 100000×0.05%=50, total opening and closing fee is 100
After applying the discounts, the actual fee expenditure is 55
Summary of Binance fee discount plans
Invitation code discount: bind the invitation ID during registration (different invitation IDs have different discounts)
BNB deduction: needs to be enabled in the personal center (for spot trading, place BNB in the spot account; for contract trading, transfer BNB to the contract account)
Trading pair discounts: spot FDUSD trading pair limit orders have a 0 fee rate; contract USDC trading pair limit orders have a 0 fee rate
Notes
The invitation code cannot be changed later; if not filled in or no discount applied, there are certain operational methods
Avoid frequently inviting oneself with multiple accounts to prevent risk control issues
Complete KYC and enable two-factor authentication to ensure account security

In practical tests of 1000U contract trading, the generated fees are nearly as high as the principal, with over 400U deductible. For users trading in the crypto circle, binding an invitation code to enjoy fee rebates is particularly important.
