How AffMiss scores crypto exchange fees.

The AffMiss fee index is a number out of ten calculated from three fees that each exchange publishes for its base tier: futures taker, futures maker and spot. It uses fixed formulas, and the fees come from the exchanges’ own pages, with a source and a date. It is not a rating of safety or quality, and no funded test stands behind it.

The formulas and their weights

Each fee, in percent, is mapped onto a score from 0 to 10, limited to that range and rounded to one decimal. A lower fee gives a higher score.

AreaWeightFormulaExamplesWhy it is included
Futures taker fee4010 − (fee − 0.02) × 1000.05% → 7.0 · 0.035% → 8.5Market, stop and take-profit orders all pay the taker rate, and it is where venues differ most.
Futures maker fee3010 − fee × 2000.02% → 6.0 · 0.01% → 8.0The rate for limit orders that rest in the book. Most large venues publish the same 0.02%.
Spot fees3010 − (maker + taker) ÷ 2 × 400.10% / 0.10% → 6.0 · 0% / 0.05% → 9.0The average of both sides at the base tier, for the venue’s main pair group.
Options fees—10 − (maker + taker) ÷ 2 × 1000.02% / 0.03% → 7.5 · 0.03% / 0.03% → 7.0Scored only for venues with an options schedule on record. Not part of the fee index; used in the options ranking.

A worked example: MEXC

MEXC publishes 0.01% maker and 0.04% taker on perpetual futures and 0% / 0.05% on spot.

Futures taker fee: 8.0 × 40

Futures maker fee: 8.0 × 30

Spot fees: 9.0 × 30

(8.0 × 40 + 8.0 × 30 + 9.0 × 30) ÷ 100 = 8.3

The same arithmetic is printed on every review, so any score on the site can be recomputed.

How a fee is read

Step 01

Read the venue’s own fee page

Rates are taken from the exchange’s fee schedule or help centre, never from another comparison site.

Step 02

Use the base tier

The rate a new account pays with no volume, no token holdings and no promotion. Tier names differ: VIP 0, LV0, Regular, Standard.

Step 03

Record the source and the date

Every review links the page the rate was read from and prints the day it was read.

Step 04

Resolve conflicts upward

If a venue’s own pages state different rates, the higher one is used and the conflict is described in the review.

Step 05

Apply the formulas

Each fee is mapped onto 0–10, clamped to that range and rounded to one decimal. The index is the weighted sum, rounded once.

Step 06

Mark what is missing

Anything not read, including every funded test, is listed as pending on the review.

What the fee index does not measure

These limits matter more than the score. A venue can have the lowest published fees and still be the wrong place for your money.

Funded testing

AffMiss has not deposited, traded or withdrawn on any venue. No fill quality, slippage, withdrawal time or support response is claimed anywhere on the site.

Safety and solvency

The fee index says nothing about custody, reserves, regulation or security history.

Spread, slippage and funding

These are real costs and can exceed the trading fee. They depend on the market and your order, and are not measured.

Withdrawal fees

Set per coin and network and changed often. No dated reading has been recorded yet.

Availability

Whether a venue accepts customers in your country, and which products it offers there, is not scored.

How the rankings by need re-weight it

The pages under Best use the same fee scores with different weights: futures (taker 60, maker 40), low fees (maker 50, taker 30, spot 20) and options (options 60, taker 25, maker 15). A venue is ranked only if it lists the product and its schedule is on record.

Methodology questions

Three published base-tier fees are each mapped onto a 0–10 scale with a fixed formula: futures taker (weight 40), futures maker (weight 30) and spot fees (weight 30). The index is the weighted sum divided by 100, rounded to one decimal.
