What win rate do I need to break even after commissions and slippage?

How this is calculated

• Breakeven win rate equals (average loss plus cost per trade) divided by (average win plus average loss), expressed as a percent.
• This is the standard risk/reward breakeven formula with your per-trade cost folded in on both sides, since a flat cost is paid whether the trade wins or loses.
• Without any costs, the formula reduces to average loss divided by (average win plus average loss), the plain reward-to-risk breakeven rate.
• The "cost drag" figure shows how many extra percentage points of win rate your commissions and slippage are forcing you to find, just to stay flat.
• This tool uses the average win and loss size you enter. If your actual trade sizes vary a lot, results are only as accurate as the averages you provide.
