Crypto Trading Fees Explained: Spot vs Futures, Maker vs Taker (2026)

Trading fees are the money every crypto trader pays and almost nobody actually calculates. This guide settles it: the real difference between Maker and Taker is providing liquidity vs consuming it; the only formula is fee = notional value × rate; spot charges on the trade amount, futures charge on notional value (margin × leverage). The core takeaway: futures rates (0.02%–0.05%) look like half of spot (0.10%), but because futures charge on notional value, the same capital at 10× leverage costs 5× more in fees. Includes a Binance vs OKX rate table, an order-type decision table, worked examples, and 6 mistakes beginners make.
