Risk/Reward Ratio — The Complete Guide

How the R:R ratio determines whether your trading strategy can be profitable long-term.

What Is the Risk/Reward Ratio?

The risk-to-reward ratio (R:R) compares how much you stand to lose on a trade versus how much you stand to gain. A ratio of 1:3 means you're risking 1 unit to potentially gain 3 units.

R:R = Potential Reward / Potential Risk = |TP − Entry| / |Entry − SL|

Why R:R Is the Most Important Metric

Here's the key insight: you don't need to win most of your trades to be profitable. The R:R ratio determines the minimum win rate you need:

R:R RatioBreakeven Win RateImplication
1:150%Need to win half your trades
1:233.3%Only need 1 in 3 trades to win
1:325%Only need 1 in 4 trades to win
1:516.7%Only need 1 in 6 trades to win

This is why professional traders focus on R:R rather than win rate. A strategy with a 30% win rate and 1:3 R:R is highly profitable.

How to Calculate R:R for Any Trade

  1. Identify your entry price — Based on your analysis
  2. Set your stop loss — At a logical support/resistance level
  3. Set your take profit — At the next significant level
  4. Calculate — R:R = distance to TP / distance to SL

Example

  • Entry: 1.0800
  • Stop Loss: 1.0770 (30 pips risk)
  • Take Profit: 1.0890 (90 pips reward)
  • R:R = 90/30 = 1:3

Minimum R:R for Different Trading Styles

  • Scalping: 1:1 to 1:1.5 (high win rate needed)
  • Day Trading: 1:2 minimum (standard approach)
  • Swing Trading: 1:2 to 1:4 (bigger targets with wider stops)
  • Position Trading: 1:3 to 1:10 (trend following with large targets)

Common Mistakes

  • Forcing R:R by using unrealistic take profits — A 1:5 R:R is meaningless if the take profit is above major resistance. Use realistic levels.
  • Using tight stops for better R:R — This worsens your win rate. Place stops at logical levels, not arbitrary ones.
  • Ignoring R:R completely — Trading without considering R:R is essentially gambling.
  • Moving your take profit closer — This reduces your R:R and kills your edge over time.

FAQ

Is a 1:1 risk/reward ratio bad?

Not necessarily. Scalpers often use 1:1 successfully because they achieve high win rates (60-70%). However, for most trading styles, 1:2 or higher gives you a much bigger edge.

Should I skip trades that don't meet my minimum R:R?

Yes. Discipline is key. If a setup only offers 1:0.5 and your minimum is 1:2, skip it. There will always be more opportunities. This is one of the hardest but most impactful habits to develop.
