Formulas
Trade size × fee rate2 × one-side feeRound-trip cost × number of round tripsExample
1,000 USDT per trade, 0.1% fee, 10 round-trips a day for 365 days: daily cost = 2 USDT, yearly ≈ 730 USDT — about 73% of a single-trade size.
Why frequency matters
The higher your trading frequency, the more fees typically affect final returns. Always confirm a strategy is net-positive after fees before going high frequency.
FAQ
How are crypto trading fees calculated?
Fee = trade size × fee rate. Spot trading typically charges on both sides, so a round trip costs roughly 2× the one-side fee.
How big is the fee impact for high-frequency trading?
At 0.1% with 10 round-trips a day, annual fees can exceed 70% of your per-trade capital — grid and market-making strategies must include fees in their math.
