How to calculate trading fee savings from a rebate
To estimate what a rebate saves you, multiply your trading volume by the fee you actually pay, then by the rebate share. Use the volume on the market the rebate covers and your real mix of maker and taker trades after discounts, then check the period and the cap. The result is an estimate, not a promise.

The arithmetic behind a fee rebate is short. Getting an honest number out of it takes a little more care: the volume has to be the right volume, the fee has to be the fee you really pay, and the rebate has to be the one that applies to your account for as long as you will trade. This guide goes through each input, then puts them together in one worked example.
The formula
Three lines are enough:
- Fees paid = trading volume × fee rate.
- Rebate = fees paid × rebate share.
- Effective fee rate = fee rate × (1 − rebate share).
Everything else is about choosing the right inputs. The result is always an estimate: the exchange calculates the real rebate by its own rules, and only your account history shows what actually came back.
Step 1: find the volume that counts
Volume is the value of every fill, on both sides of the trade. Buying a coin and selling it later counts twice — once for the buy and once for the sell. Many people underestimate their volume by half because they count the money they put in rather than the round trips they make with it.
Only volume on the market the rebate covers counts. If the rebate applies to spot and you also trade futures, split the two. A month is a practical unit: most exchanges show recent monthly volume in the account, and VIP tiers are usually based on it too.
Step 2: use the fee you actually pay
The base-tier fee in the schedule is a starting point, not necessarily your fee. Three things change it:
- Your maker and taker mix. Limit orders that wait in the book pay the maker fee; market orders pay the taker fee. Your trade history shows the role of every fill, and the share of each gives you a weighted average fee. See maker vs taker fees for how each order type is classified.
- Discounts. Paying fees with the exchange's own token or reaching a VIP tier lowers the fee, and with it the rebate.
- The market. Futures fees differ from spot, and on futures the fee is charged on the full position value.
Base-tier spot fees for every exchange we cover, with the rebate already applied, are in this table:

Step 3: apply the share, the period and the cap
Multiply your fees by the rebate share, then check two limits. If the rebate lasts a fixed period after sign-up, count only the months inside it. If it has a cap, it stops once the cap is reached, however much you trade afterwards. A rebate that looks large per month can be modest over a year if the period is short, and the other way round.
Each exchange page shows the share, the period and the cap with the date they were checked. For KuCoin, for example: rebate share 60%verified Oct 2, period to be confirmed, cap to be confirmed.
A worked example
The example uses the weighted fee, not the taker fee alone. Using the taker fee for every trade would overstate both the fees and the rebate, and make one exchange look better or worse than it is for you.
How do futures change the calculation?
On futures the fee is charged on the notional value of the position: its full size including leverage, not the margin you deposit. Opening and closing a leveraged position therefore produces volume many times larger than your margin, and fees grow with it. Two consequences follow. The rebate matters more in absolute terms, and so does the risk. And many new-account rebates do not cover futures at all, so check the market before counting on one. Funding payments are separate from trading fees and are not reduced by a rebate.
Using the calculator
The calculator below does the arithmetic with each exchange's current fee and rebate share. Enter your monthly volume and it shows the estimated fees and the part returned. Values marked as an example rate are there only to show how the calculation works; they are not confirmed terms.

The comparison page runs the same estimate across all exchanges side by side.
What the estimate leaves out
- Spread and slippage. Taker orders cross the spread, and large orders can move through several price levels. Neither shows up as a fee.
- Fees charged in the coin you receive. On some exchanges a buy is charged in the asset bought, so the value of the fee — and of the rebate — moves with that asset's price.
- Withdrawal and network fees, which no trading rebate reduces.
- Timing and rounding. Rebates are credited on the exchange's schedule, so one month's trading can be split across two payouts.
- Rule changes. Exchanges change fees and partner terms. We show the date each number was checked, and the calculator uses only the current values.
Common mistakes
- Counting only the buys instead of the full round trip.
- Using the taker fee for every trade — or the maker fee for every trade.
- Ignoring the period and the cap and simply multiplying one month by twelve.
- Comparing headline fees instead of the effective fee after the rebate.
- Forgetting that a rebate applies only to accounts opened through a partner link or code. The guide on what a fee rebate is explains why.
Frequently asked questions
Do both the buy and the sell count as volume?
Yes. Every fill is volume, so a round trip counts twice. That is also how exchanges measure volume for VIP tiers.
Which fee should I use: maker or taker?
Your real mix. Check your trade history for the share of maker and taker fills and use the weighted average.
Why is my real rebate different from the calculator?
Discounts, the maker and taker mix, the period, the cap and the payout schedule all move the result. The calculator gives an estimate; the exchange's rebate history shows what was paid.
