Trading fees are what an exchange charges to execute your order, usually between 0.1% and 0.5% of the trade for retail volumes. That percentage is the part everyone compares, and on thin markets it is frequently the smallest of the three costs you pay. The other two, spread and slippage, appear in no fee schedule and can exceed the advertised rate many times over.
The three costs of a trade
Only one gets advertised. The other two you pay anyway.
The fee. A percentage the exchange charges, typically between 0.1% and 0.5% for retail volumes. Published. The one everyone quotes.
The spread. The gap between the highest price a buyer will pay and the lowest a seller will accept. Buy at market, and you pay the higher side; sell at market, and you receive the lower one. Nobody invoices you for it, and you pay it on every single trade.
Slippage. The extra cost when your order exceeds the volume available at the best price, climbing through worse levels until filled.
On a deep Bitcoin market, the second and third are negligible. On a small-cap token they can dwarf the fee entirely. Among the ways people misjudge what trading costs them, comparing exchanges on the headline percentage alone is the most common.
Maker and taker fees
Two different rates get charged by most exchanges, and the difference is not arbitrary.
A maker places an order that rests in the book, adding liquidity. A taker executes immediately against those resting orders, removing it.
Takers get charged more, and some platforms pay makers a small rebate. The logic is straightforward: a book with no resting orders is untradeable, so the platform pays for the orders that make trading possible and charges the traders who consume them.
In practice, a limit order that waits usually pays the maker rate. A market order always pays the taker rate. Trade often and that gap compounds.
Fee tiers
Almost every exchange discounts by volume.
Calculated on trailing 30-day trading volume, tiers step down as volume rises. Some platforms also discount for holding their native token, which is how $MBG works on mb.io.
Two things are worth checking on any tier table. Whether the qualifying volume is measured across all pairs or only some, and whether the tier resets monthly in a way that could move you back up a bracket unexpectedly.
Deposit, withdrawal, and conversion costs
Trading fees are not the only line item on an exchange, and the ones that catch people out tend to be the ones attached to getting money in and out rather than to trading itself.
| Fee type | What it covers | Typical range |
|---|---|---|
| Trading fee | Executing a buy or sell | 0.1% to 0.5% for retail volumes |
| Deposit fee | Funding the account | Often free by bank transfer, higher by card |
| Withdrawal fee | Moving crypto off the platform | Varies by network, cents to dollars |
| Fiat withdrawal fee | Sending money back to a bank | Flat fee or small percentage |
| Conversion spread | Simplified buy and swap interfaces | Embedded in the rate, often wider than the order book |
That last row deserves attention. Convenient as a one-click buy button is, it frequently quotes a wider spread than the same trade placed on the order book. The cost is real and does not appear as a fee.
Card versus bank transfer
Here is the single largest avoidable cost for most people entering crypto, and it has nothing to do with the trading fee itself.
Settling in minutes, card purchases carry the highest charges, and some issuers additionally treat them as a cash advance with its own fee and interest terms. Bank transfers take hours to days and cost a fraction as much.
For a small first purchase the difference is trivial. For anything larger, the transfer route usually costs materially less, and speed is the only thing you give up.
How to calculate what you actually paid
One calculation cuts through it all.
Divide the crypto you received by the money you spent, which gives your effective price. Compare that to the market price at the moment you traded. In the gap sits your total cost: fee, spread, slippage, and any embedded conversion margin combined.
Anyone trading frequently should run this occasionally rather than trusting the advertised rate. What matters is the round trip, since entering and exiting a position means paying twice.
How traders reduce costs
- Use limit orders where execution speed is not critical, to capture the maker rate and avoid crossing the spread.
- Check book depth against your order size before trading anything substantial.
- Trade the deepest pair. The same asset can be liquid against USDT and expensive against a less common quote currency.
- Fund by bank transfer rather than card. Beyond a small purchase, the gap is large.
- Compare withdrawal networks, since the same asset can cost cents on one network and dollars on another.
- Watch total round-trip cost, not the fee on a single leg.

Frequently asked questions
What is a typical crypto trading fee?
Between roughly 0.1% and 0.5% per trade for retail volumes on most centralized exchanges, with discounts as trading volume rises. Alongside the spread and slippage, the fee is only one of three costs.
What is the difference between a maker and a taker fee?
Resting in the book and adding liquidity, a maker's order pays the lower rate. Executing immediately against existing orders and removing liquidity, a taker's pays the higher rate.
Why is the spread not listed as a fee?
Because no exchange charges it directly. Sitting between the best buy and sell price, it gets paid when you cross from one side to the other. On thin markets it frequently exceeds the advertised fee.
Is it cheaper to buy crypto with a card or a bank transfer?
Bank transfer. Almost always. Settling faster, cards cost considerably more, and some issuers treat crypto purchases as a cash advance with additional charges.
How do I calculate what a trade really cost me?
Divide the crypto received by the money spent to get your effective price, then compare it to the market price at that moment. Covered by the gap are fee, spread, slippage, and any embedded conversion margin.
Do exchanges charge for deposits and withdrawals?
Often free by bank transfer, deposits usually are not by card. Withdrawals carry a network fee that varies enormously by blockchain, from cents on some networks to dollars on others.
Can I reduce my trading fees?
As trading activity rises, volume tiers lower the rate. Limit orders capture the cheaper maker rate, and some platforms discount for holding their native token, as $MBG does on mb.io.
Why is the one-click buy price worse than the order book price?
Embedded in the quoted rate of simplified buy interfaces is a spread. It does not appear as a fee, and it is frequently wider than what the same trade would cost placed directly on the order book.
