Why risk:reward decides everything

The risk-reward ratio compares what you stand to lose (entry to stop) with what you plan to make (entry to target). It matters because it sets the win rate you need just to break even:

Break-even win rate = 1 ÷ (1 + RR)

At 1:1 you must win 50% of trades to stay flat. At 1:2 only 33.4%. At 1:3, a mere 25% win rate breaks even — you can be wrong three times out of four and still not lose money. This is why many profitable traders lose more often than they win.

Use the ratio as a filter: if a setup can't offer at least 1:1.5 to a realistic target, most traders are better off skipping it.

Frequently asked questions

What is a good risk-reward ratio?

1:2 or better is the common benchmark for swing trades — it breaks even at just a 33% win rate. Scalpers may accept 1:1 with high win rates. Below 1:1 you need to win more than half your trades just to stay flat, which is hard to sustain.

Should I ever take a trade with less than 1:1?

Only if your verified win rate genuinely exceeds the break-even rate this calculator shows — for 1:0.5 that means winning more than 67% of the time. Most traders overestimate their win rate; a journal tells you the truth.

Is planned RR the same as realised RR?

No. Planned RR uses your target; realised RR (the R-multiple) uses your actual exit. Comparing the two across many trades shows whether you cut winners early — one of the most common leaks.
