Crypto Trading Fee Calculator
See how much you pay in exchange fees per trade and across many round trips. Useful for checking whether an active strategy's targets clear its fees.
Estimate based on a flat percentage fee per side. It assumes the same trade size each time and does not include slippage, funding, or withdrawal fees.
Why Fees Add Up
Every round trip is two taxable events for fees: the buy and the sell. At 0.1 percent per side, a $5,000 trade costs $10 to open and close. That looks small until a bot does it a hundred times, which is $1,000. If your average profit per trade is smaller than the round-trip fee, the strategy loses to fees even when it is right more often than not.
One subscription, no per-trade markup
TradeArmor charges a flat monthly price with no per-trade fee of its own, so the only trading cost you pay is your exchange's. Backtesting and paper trading let you check a strategy's net edge after fees before going live.
Frequently Asked Questions
How are crypto trading fees calculated?
Each trade is charged a percentage of its value. A round trip has two trades, a buy and a sell, so it is charged twice. Multiply your trade size by the fee rate to get one side, double it for a round trip, and multiply by the number of round trips for the total.
What is the difference between maker and taker fees?
A maker order adds liquidity to the order book and usually pays a lower fee. A taker order removes liquidity and usually pays a higher fee. Enter whichever rate applies to how your orders fill.
Do trading fees matter for a bot?
Yes. A bot that trades often pays fees often, so a strategy with small targets can give back much of its edge in fees. This calculator shows how fees scale with the number of round trips.
Does TradeArmor add its own per-trade fee?
No. TradeArmor charges a flat monthly subscription with no per-trade fee and no execution markup. You only pay your exchange's normal trading fees.
How can I reduce trading fees?
Use maker orders where possible, trade on exchanges or tiers with lower fees, and avoid strategies whose profit targets are smaller than the round-trip fee. The calculator helps you check that last point.
