R:R Ratios Explained: Why 1:2 Beats 1:1 Over Time

Imagine two traders with identical 50% win rates. Trader A risks $100 to make $100 on every trade (a 1:1 ratio). Trader B risks $100 to make $200 (a 1:2 ratio). Over 100 trades with the same win rate, Trader A breaks roughly even before costs. Trader B is up significantly. Same accuracy, completely different outcome — the ratio did all the work.

What risk:reward actually measures

A risk:reward (R:R) ratio compares how much you stand to lose if your stop is hit against how much you stand to gain if your target is hit. A 1:2 ratio means your potential reward is twice your risk. It says nothing about how likely the trade is to work — that's a separate question entirely.

This is why R:R and win rate have to be considered together, never in isolation. A strategy needs a win rate high enough to be profitable at its given R:R. The lower your R:R, the higher your win rate needs to be just to break even.

The break-even math

At a 1:1 ratio, you need to win more than 50% of trades just to profit (after costs, realistically closer to 52–55%). At 1:2, your break-even win rate drops to roughly 33%. At 1:3, it drops to about 25%. This is why traders who consistently take 1:2 or better setups can be wrong most of the time and still build an account — the math is doing the heavy lifting, not their prediction accuracy.

Why 1:1 is the hardest ratio to trade profitably

1:1 setups feel comfortable because the numbers are symmetric, but they leave zero margin for error. Slippage, spread, and commissions all eat into that theoretical 1:1, quietly pushing the real break-even win rate above 50%. A 1:2 setup gives you room to be wrong more often than you're right and still come out ahead — which, for almost every trader, is the more realistic long-run scenario.

None of this means chase huge ratios blindly — a 1:10 target that price almost never reaches is just as unhelpful as a weak 1:1. The goal is a ratio your actual win rate can support, checked with real numbers rather than a gut feeling.
