Crypto exchange fees apply on both the buy and the sell side, and they quietly reduce your real profit compared to the raw price difference. This calculator shows what you actually keep, after fees.
How fees compound against you
A fee is charged both when you buy and when you sell — so a 0.5% fee actually costs you roughly 1% of your position across the full round trip, not 0.5%. On small price moves, fees can meaningfully eat into your gains.
Why this matters more for frequent trading
A single buy-and-hold trade absorbs fees just twice. Frequent trading pays the fee round-trip every time, which is why active trading strategies need a bigger edge just to overcome cumulative fee costs.
