Crypto Fee Rebate vs Trading Fee Discount: The Math

A discount lowers the fee charged at execution; a rebate returns part of an eligible fee later. Do not add the headline percentages without checking the calculation base.

The cash-flow formula

Let the undiscounted fee be F, the immediate discount be d, and a rebate on the charged eligible fee be r. Then fee charged = F × (1-d), rebate = fee charged × r, and net fee = F × (1-d) × (1-r). A venue may use a different base or exclude products, so the ledger remains authoritative.

Worked example

If the base fee is 10 USDT, the immediate discount is 20%, and the later rebate is 25% of the discounted fee, the exchange charges 8 USDT and returns 2 USDT. Net cost is 6 USDT. Adding 20% and 25% and calling it a 45% reduction would incorrectly imply 5.5 USDT.

VIP, token payment, and maker/taker

A common order is product and account tier, token-payment or campaign discount, execution charge, then rebate settlement. Maker and taker rates can have different bases. Compare published fees with the fee comparison tool, estimate with the rebate calculator, and verify with fills.

Why an “up to” rate is not your rate

Product eligibility, campaign dates, region, minimum settlement, VIP interactions, and the definition of eligible fee can reduce the realized benefit. The strongest evidence is executed notional, fee charged, and rebate received.

Convert the result to basis points

One basis point is 0.01%. A net round-trip cost of 12 bps is about 12 USDT per 10,000 USDT notional. Basis points let fees, spread, slippage, and funding share one comparison unit.

FAQ

Does a referral make the base fee higher?

It should not simply raise the published base fee; verify the account tier and actual order ledger.

Is a discount always better than a rebate?

A discount improves immediate cash flow; a rebate lowers final cost if it settles reliably.

Why can a calculator differ?

The assumed fee base, maker/taker mix, exclusions, and settlement rules may differ from the real account.

Bottom line

Compare cash flows rather than labels. The fee charged minus the rebate actually received is the effective fee.
