What a $10,000 trade actually costs on each major exchange

The same $10,000 bitcoin buy cost about $10 on the cheapest venue we measured and about $62 on the most expensive. Neither number appears on either exchange's fee page, because the published taker fee is only one of the three things you actually pay.

We measured this rather than compiling it: for the exchange rating we walked each venue's live public order book and filled the same order, then added the venue's own published fee. The result is the effective cost — fee, plus spread, plus the slippage the order itself causes.

What you actually pay

Three costs stack on every market order, and only the first is advertised.

• The taker fee. Published, predictable, and usually the smallest of the three on a thin book.
• The spread. The gap between the best bid and the best ask. You cross it the moment you trade, and it is not a fee anyone charges you — it is simply the price you get.
• Slippage. Your own order eating through the book. On a deep venue a $10,000 order barely registers; on a thin one it moves the price against you before it fills.

This is why the comparison sites that rank exchanges on published fees are ranking one third of the answer.

The measured numbers

At the moment we measured, Binance and OKX were joint cheapest at about 0.10% — essentially the published taker fee, with slippage too small to register against books that deep. Kraken came in at 0.26%, and Coinbase at roughly 0.60%: more than six times the cheapest, for an identical trade.

On $10,000 that is a difference of about $52. On a portfolio that trades monthly, it is several hundred dollars a year for exactly the same asset arriving in exactly the same wallet.

Why the cheapest venue is not the answer

Our ranking does not put the cheapest exchange first, and the reason is deliberate. Custody carries 40% of the score because an exchange is a custodian before it is a marketplace: a 0.5% cost difference is worth $50 on a $10,000 trade, while a custody failure is worth $10,000.

There is also a practical problem with the cheapest number in the table. It belongs to the global order book, and Binance no longer serves EU residents, has never served US retail, and stopped taking new UK users in 2023. A fee advantage is worth nothing on a venue that cannot open an account for you.

The costs nobody puts in a comparison

Two more charges routinely exceed the trading fee, and neither appears in a fee comparison.

• The convert button. The one-click buy flow inside most exchange apps prices at a spread rather than a fee, and it is consistently worse than the same trade placed on the venue's own order book. Learning the trading interface is the highest-value ten minutes available to a new user.
• The withdrawal markup. Many venues charge a network fee well above what the network actually charged at that moment. It is a per-transaction cost, so it hits hardest for people moving small amounts often.

How to pay less without changing exchange

• Use the trading interface, not the simple buy button.
• Use limit orders where you can. A maker fee is lower than a taker fee almost everywhere, and you stop paying the spread.
• Batch withdrawals rather than moving small amounts repeatedly.
• Check the effective cost on your own trade — the fill price against the mid-market rate at the moment you traded. It is the only number that describes what you actually paid.

A fee schedule tells you what a venue charges. Only a filled order tells you what it costs.

The short version

Effective cost ranges from about 0.10% to 0.60% across the major venues for the same trade, and the published fee explains less than half of that spread. Pick the venue on custody evidence and availability first, then reduce what you pay on it using the order book rather than the buy button.
