How Commission-Free Crypto Trading Platforms Make Money

Commission-free crypto trading is not free. The cost moved from a visible commission line into the price you are quoted, and most retail investors never see the difference. Understanding how a platform charges is now the difference between paying a few dollars per trade and paying ten times that.

Two ways platforms charge for the same trade

Crypto venues use two pricing models. Exchanges such as Coinbase and Kraken publish a maker-taker schedule: a percentage of each trade that falls as your 30-day volume rises. Makers add liquidity by posting an order that waits; takers remove it by trading against an existing order. Takers almost always pay more.

Brokerages that advertise zero commission use the second model. They quote you a price that is slightly worse than the market price and keep the difference, known as the spread. Nothing appears on the receipt, so the trade looks free, and the cost is still real.

What that means in practice

Robinhood is the clearest worked example, because it discloses the arrangement. Under the fee schedule that took effect in June 2026, orders routed to a market maker earn Robinhood 95 cents for every $100 of order volume, and that amount is included in the spread you are quoted. Its smart exchange routing is charged openly instead, on a volume-based scale running from 0.95% down to 0.03% for the highest-volume traders. A detailed breakdown of both routes is set out in Cryptsy’s Robinhood crypto fees breakdown.

Put a number on it. On a $1,000 buy, a 0.95% cost is about $9.50. Doing that twice a week for a year is roughly $990, on an account that was marketed as commission-free. The same trade on a published maker-taker schedule at 0.4% costs about $4.

Why the spread model persists

Spread pricing is not inherently dishonest, and it has a defence: the platform takes on the risk of filling your order immediately at the quoted price, and beginners get a simple, single number rather than a fee table. The problem is comparability. A published percentage can be compared across venues in seconds. A spread has to be measured trade by trade against the mid-market price, which almost nobody does.

That asymmetry shows up in behaviour. Investors who cannot see a fee trade more often, and frequent small trades are exactly where percentage costs compound fastest.

How to work out what you are actually paying

  • Compare the price you are quoted against the mid-market price on a public exchange at the same moment. The gap is the spread, in cash.
  • Check whether your platform publishes a maker-taker schedule, a spread, or both, and which one applies to the order type you use.
  • Look up where your volume sits in the tier table. The headline low rate is usually reserved for traders far above retail size.
  • Count withdrawal and network fees separately. Moving coins off a platform is priced on its own, and it is where a cheap trade can become an expensive one.
  • Multiply the percentage by how often you actually trade, not by a single transaction.

The takeaway

“Zero commission” describes one line of the bill, not the bill. Ask any platform a single question before funding an account: on a $1,000 order, in dollars, what do you keep? A venue that publishes a schedule can answer immediately. One that cannot is telling you something useful too.
