Crypto Exchange Fees Decoded: Maker, Taker, Spreads and Funding

Every exchange advertises a fee, but what you pay on a trade has several layers: the trading commission, the spread between buying and selling prices, charges to move money in and out, and, for derivatives, recurring funding payments. Two platforms with the same headline rate can produce very different bills. Understanding the layers is the cheapest way to cut costs, and it requires no market view at all.

Maker and taker

• A maker places a limit order that waits in the order book, adding liquidity. A taker places an order that fills immediately against existing orders, removing liquidity. Takers usually pay more.
• Published base-tier spot rates as of October 2026: OKX 0.08% maker and 0.10% taker; Binance 0.10% for both; Mercado Bitcoin 0.30% and 0.70% for monthly volume up to R$10,000; Kraken Pro 0.40% and 0.80%; Coinbase Advanced 0.60% and 1.20%. Bitfinex charges zero.
• Rates fall with 30-day volume and sometimes with token holdings, such as 25% off at Binance when paying in BNB or 20% at KuCoin with KCS. Since July 2026, Kraken also counts assets held on the platform.
• Simple arithmetic shows the gap: a R$10,000 order costs R$70 at a 0.70% taker rate and R$30 at a 0.30% maker rate.

The cheapest trade is often the one you are willing to wait for.

The costs not on the fee page

The one-tap buy button in many apps does not use the order book. It quotes a price that includes a spread, the gap between what you pay and the market rate, and that cost rarely appears as a separate line. Converting between currencies can add another margin. Moving coins out costs a network fee that depends on the blockchain and the asset, and many platforms set minimum withdrawal amounts. Some costs are zero: Mercado Bitcoin, for example, does not charge to deposit or withdraw reais and charges no fee on crypto-to-crypto pairs, while Bitfinex, which charges no trading fees, keeps lending and withdrawal fees. Read the full fee schedule, not just the headline.

Derivatives: funding rates

• Perpetual futures have no expiry. To keep their price close to the spot market, long and short holders exchange periodic funding payments, often every eight hours, though some contracts settle more frequently.
• When the rate is positive, longs pay shorts; when negative, shorts pay longs. Rates move with market demand and can change sharply.
• Funding and trading fees are charged on the full leveraged position, not on your margin, so leverage multiplies costs as well as exposure.
• Liquidations can carry their own fees, and borrowing on margin accounts accrues interest.

Risk note: this is general information, not investment advice or a recommendation of any platform. Fees change frequently, so check each exchange's official schedule before trading. Lower costs do not reduce market risk: cryptoassets are highly volatile, and leveraged products can lose more quickly than spot holdings.
