The formula
Round-trip cost = trade size × fee rate × 2. Annual cost = round-trip cost × trades per year.
How crypto trading fees actually work
Every trade on a centralised exchange carries a small percentage fee, charged twice: once to open and once to close. The maker rate applies when you place a limit order that rests in the book and adds liquidity. The taker rate applies when you place a market order that fills immediately and removes it. Takers pay more, because patience is what the exchange is buying from makers.
That single habit is worth more than most people assume. On a venue charging 0.02% maker and 0.06% taker, impatience costs three times as much on every single trade, forever.
What a round trip actually costs
| Fee per side | $1,000 round trip | 20 trades / month | Per year |
|---|---|---|---|
| 0.05% | $1.00 | $20 | $240 |
| 0.08% | $1.60 | $32 | $384 |
| 0.10% | $2.00 | $40 | $480 |
| 0.60% | $12.00 | $240 | $2,880 |
| 2.50% | $50.00 | $1,000 | $12,000 |
The bottom two rows are not exotic. They are the instant-buy widget and the card purchase route, which is where a large share of first crypto purchases happen. A beginner who buys that way and trades actively can pay more in fees in a year than their entire starting balance.
Why MEXC comes out cheapest on paper
On standard published rates, MEXC charges 0% maker and 0.05% taker on spot, against 0.1% on the standard tier at Binance, OKX and Bybit. For an active trader that difference compounds: on the numbers above it is $240 a year versus $480, on a single $1,000 position.
The honest counterweight is regulation. MEXC holds no tier-one licence, restricts users in the US, UK and Canada, and routes fiat through third parties at 3-5%. Cheapest trading fees are worthless if the venue will not accept you, or will not pay you out. Read the full MEXC review including who it is wrong for before deciding on price alone.
The three costs no fee page shows you
- The spread. The gap between bid and ask is never published and is often larger than the fee on anything outside the majors. You pay it on entry and exit, exactly like a fee.
- The withdrawal fee. Set per network, flat per transaction. Moving $50 can cost proportionally more than moving $5,000, which quietly makes small withdrawals uneconomic.
- Conversion. Funding in a currency the venue does not quote adds a conversion step with its own margin, usually invisible inside the exchange rate.
This is why we time real withdrawals from funded accounts rather than reading fee pages. Published numbers are easy. Payout behaviour is the part nobody advertises.
The one edge you fully control
You cannot control where price goes. You can control the fee you pay to get in and out, and unlike direction it is knowable in advance and permanent. Over a year of active trading, the gap between 0.1% and 0.05% is real money moved from the exchange to you, with no additional risk taken.
Two habits capture most of it: use limit orders to qualify for the maker rate, and never use the instant-buy button for anything you could place on the order book.

Frequently asked
How do I calculate crypto trading fees?
Fee = trade size × fee rate, charged on the way in and again on the way out. A $1,000 trade at a 0.1% taker rate costs $1 to open and $1 to close, so the round trip is $2, or 0.2% of position value before price moves at all. Multiply by how often you trade: twenty round trips a month at that rate is $40 a month on a $1,000 position.
What is the difference between maker and taker fees?
A maker places a limit order that rests in the order book and adds liquidity, paying the lower rate. A taker hits an existing order with a market order and removes liquidity, paying the higher rate. The gap is routinely two to three times, so a trader who compares venues on the advertised maker fee and then places nothing but market orders pays far more than they planned.
Which crypto exchange has the lowest fees?
On published standard spot rates, MEXC is the cheapest of the venues we track at 0% maker and 0.05% taker, against 0.1% on the standard tier at Binance, OKX and Bybit. The honest trade-off is regulation: MEXC holds no tier-one licence and restricts users in the US, UK and Canada. Cheapest is only useful if the venue will actually accept you and pay you out.
Do fee tiers and exchange tokens really reduce the cost?
Yes, and that is how most headline claims are built. Venues cut rates by thirty-day volume and by holding their own token, which is how a "0.08%" figure appears for an account that would otherwise pay 0.1%. Check whether you will actually hit the volume tier, and remember that holding a venue token is itself a position with its own risk.
What costs does the fee schedule not show?
Three big ones. The spread between bid and ask, which is not published and can exceed the fee on thin pairs. The withdrawal fee, set per network and flat per transaction, which punishes small amounts hardest. And conversion costs if you fund in a currency the venue does not quote. None of these appear on a fee page.
Why is the instant buy button so expensive?
Simple or instant buy widgets, and card purchases in particular, are a different product from the spot order book. They commonly cost 0.6% to 2.5% per transaction - ten to fifty times the spot taker rate. It is the easiest button on the screen and it is where most beginners buy, which is why their returns look worse than their analysis.
Do fees matter if I only trade occasionally?
Less, but not never. On two trades a year the difference between 0.05% and 0.1% is irrelevant. On twenty trades a month it is often larger than the entire edge a strategy has. Fee sensitivity scales with frequency, so the right question is not "are fees low" but "are fees low for how I actually trade".
Are futures fees different from spot fees?
Yes, and usually lower per side, but perpetual futures add funding every eight hours, which is a running cost spot does not have. A perp held for a week in a crowded trade can pay more in funding than it would cost in spot fees to simply own the asset.
Is this fee calculator free?
Yes, no sign-up. It runs in your browser and the numbers never reach us.
