Risk/Reward Ratio and Break-Even Win Rate
Calculate gross and net risk/reward, account for costs, and connect payoff size to break-even win rate and scenario expectancy.
In this lesson
- Calculate a simple two-outcome break-even win rate.
- Explain why a favourable target ratio does not establish positive expectancy.

The short answer
If a trade models USD 100 of price loss and USD 200 of price gain, risk:reward is 1:2. The reward-to-risk multiple is 2. Some resources reverse the order when naming the ratio, so identify the numerator and denominator rather than relying on the label.

Write the ratio in a clear direction
Those numbers describe outcomes under assumptions. An attractive ratio does not establish how often the target will be reached, whether a stop will execute as expected, or whether the trade is suitable. Our risk/reward calculator uses cash amounts in a single currency, so prices and contract units must be converted before entry.
Include costs on both outcomes
Suppose the same trade has USD 10 of additional round-trip costs whether it wins or loses. The net winning outcome is 200 − 10 = USD 190. The losing outcome is a USD 100 price loss plus USD 10 costs, or USD 110 lost.
Net reward = gross price gain − additional costs
Net loss magnitude = gross price loss + additional costs
Net reward-to-risk multiple = net reward ÷ net loss magnitude
The net multiple is 190 ÷ 110 ≈ 1.7273, giving risk:reward of about 1:1.73. Do not enter a net result and subtract the same costs a second time. The tool assumes equal extra costs on winning and losing trades; real cost schedules may differ.
Derive the break-even win rate
Let W be the positive net gain on a winning trade and L the positive amount lost on a losing trade. With only those two fixed outcomes, break-even occurs when the winnings equal the losses.
Break-even win rate = L ÷ (W + L) × 100
With no costs, the USD 100/200 example needs 100 ÷ 300 = 33.3333%. With the costs above, it needs 110 ÷ 300 = 36.6667%. This is a threshold under the model, not an estimate of the win rate a strategy will achieve.
If costs equal the gross gain, winning trades return zero after those costs: only a 100% win rate breaks even in this two-outcome model. If costs exceed the gross gain, even the winning outcome loses money and no possible win rate can break even.
Compare break-even rates across targets and costs
Fix gross price risk at USD 100 and compare four gross targets. The additional cash cost below is the same on a win and a loss. It is separate from any spread already captured in the executable-price difference.
| Gross risk:reward | No costs | USD 5 costs | USD 10 costs |
|---|---|---|---|
| 1:1 | 50.00% | 52.50% | 55.00% |
| 1:1.5 | 40.00% | 42.00% | 44.00% |
| 1:2 | 33.33% | 35.00% | 36.67% |
| 1:3 | 25.00% | 26.25% | 27.50% |
For 1:1.5 with USD 5 costs, a win nets USD 145 and a loss costs USD 105. The break-even rate is 105 ÷ (145 + 105) × 100 = 42%. Equal costs cancel from the denominator, but increase the loss in the numerator.
The thresholds describe long-run averages under these assumptions, not guaranteed results in a small sample. A larger target lowers the mathematical threshold while its probability of execution may also change. This table cannot identify an optimal ratio or prove that a 1:3 setup is better than a 1:1 setup.
Check the assumed average outcome
At an assumed 40% win rate, the cost-adjusted example has an average outcome of 0.40 × 190 − 0.60 × 110 = USD 10 per trade. At 30%, it is 0.30 × 190 − 0.70 × 110 = −USD 20. These are independently calculated scenarios, not observed trading results.
Actual trades may have partial exits, variable losses, breakeven outcomes, changing costs and correlated results. A target-based payoff is not necessarily the realised average winner. A small historical sample is also an uncertain estimate of future win rate.
Use the result to question assumptions, not to infer a proven edge. See drawdown and recovery for a separate explanation of losses over an account path, and position sizing with costs before translating a scenario into lots.

Lesson 12 checkpoint
Put the reading into practice
Work it through
For a simplified model with USD 100 lost per loser and USD 200 gained per winner, calculate the gross break-even win rate. Then explain how costs and non-target exits change the model.
