See what a round trip really costs. Enter your position and fee rates to get total fees, net profit or loss, and the breakeven price after costs.
Shares, coins, or contracts - fees are computed on price × quantity per side.
For brokers charging a fixed commission per order on top of (or instead of) a percentage.
Breakeven is the exit price where net P/L equals zero: the market must move ≈ entry fee % + exit fee % in your favour (plus any flat fees) before a trade turns profitable. Funding, spread, and slippage aren't included.
Every trade costs money twice: once when you enter and once when you exit. Those costs come as percentage commissions (often split into maker and taker rates), flat per-order fees, or both - and because they're charged on each side, the real cost of a trade is the round trip, not a single fee line. A trading fee calculator adds both sides up for your exact position size and shows what the trade must earn before you keep anything.
Fees shift your breakeven point. If you pay 0.10% to enter and 0.10% to exit, price has to move roughly 0.20% in your favour before the trade is profitable at all - more once flat fees are added, and the effect is proportionally larger on small positions. The calculator above computes that exact breakeven price for longs and shorts, which is the honest baseline for judging whether a setup's target justifies its costs.
Buy 10 units at $100 (a $1,000 position) with 0.10% per side: entry costs $1.00, and selling at $105 costs $1.05 - $2.05 round trip. Your gross gain of $50 becomes $47.95 net, and your true breakeven wasn't $100 but $100.20.
Frequent traders should care most: costs scale with turnover, not with profit. Ten round trips at 0.20% each consume 2% of traded volume - which is why fee awareness separates a strategy that works on paper from one that works in an account.
Use it two ways: after a trade, to see what you actually kept - or before one, by entering your planned exit to check whether the target clears fees by enough to be worth taking. If the breakeven move looks large relative to your target, the position is too small or the fees too high for that setup.
