How it works

Break-even win rate = (gross average loss + cost) ÷ (gross average win + gross average loss). This assumes the same average cost on winners and losers. A cost greater than the gross win makes break-even impossible under these inputs.

Worked example

A 200 average win, 100 average loss and 10 per trade in costs require 110 ÷ 300 = 36.6667% wins. Without costs, the same payoff needs 33.3333%.

What the result assumes

If your averages already include all costs, enter zero in the cost field. This is a mathematical threshold for the input averages. Payoff distributions and costs can change.
