Cheapest US Crypto Exchange: The Real Cost to Trade
The headline fee is not what you pay. We add the two costs exchanges do not advertise, half the live bid/ask spread and the slippage of actually filling your order, to the published taker fee, and rank the true cost of market-buying $10,000 of BTC on 5 US exchanges. Lower is cheaper.

Verdict: Binance.US: lowest real cost (~4.47 bps on $10,000)
Ranked by total one-way cost: base-tier taker fee + measured half-spread + measured slippage to fill $10,000. Binance.US was cheapest at about 4.47 bps (roughly $4 on a $10,000 trade), while Gemini ran about 120.19 bps ($120) — 27x more for the identical trade. The fee is one input; the spread and slippage are measured live off each order book.

How to read this
Taker fee is the published cost of a market order at the base (zero-volume) tier, what you pay before you have earned any volume discount. We use taker, not maker, because a market order is what a taker pays, and it is the honest worst case most people actually hit.Half-spread is half the live bid/ask gap, the cost of crossing from mid to the price you actually transact at. Slippage is the extra cost of size: filling$10,000 eats down the order book, so the average fill price is worse than the best quote. We measure it by walking the live book. Total is the sum, the real one-way cost of the trade in basis points.
Why the fee dominates on BTC: Bitcoin is deeply liquid, so on the majors the spread and slippage on $10,000 are a fraction of a basis point and the taker fee is almost the whole cost. That is itself a useful finding: for liquid pairs, the advertised fee really is the number to compare. The measured layer earns its keep on larger orders and on thinner, smaller-cap markets, where a low headline fee can hide a costly fill. See it in action in our real cost to trade Solana (SOL) benchmark.
Fees are one input
Cost is not the only thing that decides where to trade. API latency, available pairs, rate limits, and US eligibility matter too. We measure exchange API speed in ourlatency benchmark, and break down tools per venue across the rest of the site. For a bot, pairing a low-cost venue with deep liquidity and a nearby server is the combination that actually protects your edge.
Common questions
What is the cheapest US crypto exchange to trade on?
In our most recent run (2026-07-16), Binance.US had the lowest real cost to market-buy $10,000 of BTC: about 4.47 bps all-in (taker fee + measured spread + slippage), versus 120.19 bps at Gemini, roughly 27x more. Fees change and this re-measures, so the live table above is the current source of truth.
Why is your fee different from the exchange’s advertised rate?
We use the published TAKER fee for the base (zero-volume) tier, which is what a new trader actually pays on their first market order, not the discounted rate you only reach at high volume. On top of that we add the two costs exchanges do not advertise: half the live bid/ask spread, and the slippage of actually filling your order size against the current order book. That total is the real cost of the trade.
What is slippage, and how do you measure it?
Slippage is the extra cost of filling a larger order: you eat progressively worse prices as you consume the order book. We take a live public order-book snapshot from each exchange and walk the ask side to fill a $10,000 market buy, then compare the volume-weighted average fill price to the best ask. It is measured, not estimated, and the raw snapshot math is reproducible from the published JSON.
Does a low fee matter if the spread is wide?
No, and that is the whole point of measuring total cost. A venue can advertise a low fee but quote a wide spread or have a thin book, so your real cost is higher than a pricier-looking venue with deep liquidity. On very liquid pairs like BTC the spread is tiny and the fee dominates; on smaller coins or larger orders, spread and slippage can outweigh the fee entirely.
