Risk Reward Ratio Calculator Guide (2026): Formula, Examples & Strategy

Every trade you place has two numbers that matter more than the ticker: how much you can lose, and how much you can win. A risk reward ratio calculator gives you those numbers instantly — and if you know how to read them, you already have an edge over 90% of retail traders.

What Is the Risk Reward Ratio?

The risk reward ratio (often written R:R) compares the money you can lose on a trade against the money you can make. A 1:3 R:R means you risk one dollar to potentially make three. The higher the reward per unit of risk, the lower the win rate you need to remain profitable.

Think of the calculator as the sanity check that runs before every trade. Enter your entry, stop loss and target, and it tells you whether the maths supports the setup.

The Formula (and Why It Works)

Risk = Entry − Stop loss (for long trades).
Reward = Target − Entry.
R:R = Reward ÷ Risk.

The Bizzlytics Risk Reward Ratio Calculator also gives you the break-even win rate — the minimum percentage of trades you need to win at that R:R just to break even before fees.

The R:R Cheat Sheet

Beginner-Friendly Walk-Through

Imagine buying a stock at $100 with a stop at $95 and a target at $115. That is $5 of risk for $15 of reward — a 1:3 ratio. Now suppose your historical win rate is 40%. Expected value per trade = (0.4 × $15) − (0.6 × $5) = $6 − $3 = +$3 per trade before costs. Take 100 trades and, all else equal, expect $300 of profit.

Contrast that with a 1:1 setup where you also win 40%. Expected value = (0.4 × $5) − (0.6 × $5) = −$1 per trade. Same win rate, opposite outcome. That is why R:R is the most important number on your screen.

Three Real Trading Examples

1. Stock swing trade

AAPL entry $180, stop $174, target $198. Risk = $6, Reward = $18. R:R = 1:3. Break-even win rate 25%. You only need to be right 1 in 4 to make money.

2. Forex intraday

EURUSD entry 1.0850, stop 1.0820 (30 pips), target 1.0925 (75 pips). R:R = 1:2.5. Break-even win rate 28.6%.

3. Crypto scalp

BTC entry $60,000, stop $59,700 (0.5%), target $60,300 (0.5%). R:R = 1:1. Break-even 50%. After 0.1% fees round-trip, you actually need ~52% just to break even. Marginal at best.

How Professional Traders Use the Calculator

1. Set the stop before the target. Base your stop on structure (below support, above the swing high), not on a dollar figure. The target is what has to justify the risk — not the other way round.
2. Reject trades below your minimum R:R. Most pros pass on anything under 1:2. If the market is not offering enough reward for the risk, do nothing — the best trade is often no trade.
3. Combine with expectancy. Pair the R:R calculator with the Expectancy Calculator to translate R:R + win rate into dollars per trade.
4. Size the position last. Once R:R is validated, use the Position Size Calculator to determine how many shares/contracts fit your fixed % of account risk.

Common Mistakes to Avoid

• Moving the stop mid-trade — instantly worsens R:R and turns a good trade into a bad one.
• Cutting winners early — a 1:3 planned trade taken at 1:1 destroys the maths of your entire system.
• Ignoring fees on tight R:R — a 1:1 setup with 0.1% round-trip fee needs 55%+ win rate, not 50%.
• Treating R:R as an entry signal — R:R is a filter, not a reason to enter. You still need a trigger.
• Curve-fitting the target — inventing a bigger target after entry to make the R:R look pretty is self-deception.

FAQs

What is a good risk reward ratio?

Most professionals require at least 1:2. Trend-following systems often target 1:3 to 1:5. Scalpers may accept 1:1 but need high win rates and low fees.

How do I calculate risk reward on a short trade?

Flip the sign. Risk = Stop − Entry. Reward = Entry − Target. The Bizzlytics calculator handles both automatically.

Does R:R include commissions?

The base calculation is gross. Subtract round-trip fees from reward (or add to risk) for a net R:R. For active traders this matters more than they think.

Can I be profitable with a low win rate?

Yes — a 30% win rate at 1:3 R:R has positive expectancy. The sequence of losses will feel brutal, so you also need psychological discipline to keep sizing consistently.

How is R:R different from the Sharpe ratio?

R:R is trade-level. Sharpe is portfolio-level and measures risk-adjusted return volatility. Both matter, but R:R is where you start.

Key Takeaways

• R:R + win rate = expectancy. Neither number alone tells you if a system is profitable.
• A minimum 1:2 R:R is the industry-standard filter for discretionary trading.
• Set the stop from structure, not from a dollar amount. Set the target from real resistance/support levels.
• Never move the stop against you. Move it only to lock profit.
• Log R:R for every trade in a journal so you can prove your system has an edge — or that it does not.
