Risk/Reward Ratio Explained: Is This Trade Worth Taking?

Most traders evaluate a trade by asking: "Do I think this stock is going up?"

The right question is: "Even if I'm only right half the time, does taking this trade make me money over 100 repetitions?"

That's what risk/reward ratio answers. It's not about predicting the future — it's about making sure the math is on your side before you enter.

What Is Risk/Reward Ratio?

Risk/reward ratio compares how much you stand to lose if you're wrong versus how much you stand to gain if you're right.

A 1:2 risk/reward means: for every $1 you risk, you're targeting $2 in profit.

A 1:3 risk/reward means: for every $1 you risk, you're targeting $3 in profit.

A 1:0.5 risk/reward means: you're risking $2 to make $1. This is a losing game regardless of how good you think the setup is.

The Formula

Example: Entry at $50.00, stop at $47.50, target at $57.50

Upside: $57.50 − $50.00 = $7.50

Downside: $50.00 − $47.50 = $2.50

R:R = $7.50 ÷ $2.50 = 3:1

For every $1 you risk, you're targeting $3 in return. That's a strong setup.

Why 1:1 Is a Losing Game

At 1:1 risk/reward, your wins equal your losses. To be profitable, you'd need to win more than 50% of your trades — after accounting for commissions, slippage, and the psychological reality that most traders cut winners early and let losers run.

In practice, consistently winning 55%+ of your trades is very hard. Most experienced traders win 40-50% of their trades. At 1:1 R:R with a 45% win rate:

45 winners × $100 = $4,500 gains
55 losers × $100 = $5,500 losses
Net: −$1,000 over 100 trades

You're doing everything right except the ratio. And you're still losing money.

The Sweet Spot for Swing Traders

For swing trading specifically, I aim for a minimum of 1.5:1 and prefer 2:1 or better. Here's why:

At 2:1 R:R with a 40% win rate:

40 winners × $200 = $8,000 gains
60 losers × $100 = $6,000 losses
Net: +$2,000 over 100 trades ✓

At 2:1 R:R with a 45% win rate:

45 winners × $200 = $9,000 gains
55 losers × $100 = $5,500 losses
Net: +$3,500 over 100 trades ✓

Better R:R gives you room to be wrong more often and still make money.

Win Rate Needed at Different R:R Ratios

Here's the table every trader should have memorized. This shows the minimum win rate you need just to break even at each R:R ratio:

At 3:1 R:R, you can be wrong on 75% of your trades and still break even. Win just 35% of the time and you're growing your account.

Why a 35% Win Rate Beats 60% Win Rate

Let's compare two traders over 100 trades:

Trader A: 60% win rate, 1:1 R:R, $100 per win/loss
60 × $100 − 40 × $100 = +$2,000

Trader B: 35% win rate, 3:1 R:R, $300 win / $100 loss
35 × $300 − 65 × $100 = +$4,000

Trader B wins only 35% of their trades. They lose almost twice as often as Trader A. But they make twice as much money. This is not a coincidence — it's math.

How R:R Interacts With Your Trading Style

Tight stops mean higher R:R potential, but more frequent stop-outs. Wide stops mean fewer stop-outs, but weaker R:R.

Day traders typically use tighter stops — which is fine if they're targeting quick moves. Swing traders usually hold 2-10 days, which means wider stops but the potential for bigger moves.

For swing trading, I look for setups where:

• Natural support (prior lows, moving averages) is close enough to set a tight stop
• The next resistance level (prior highs, chart targets) is far enough to give 2:1 or better
• The ratio of distance-to-resistance versus distance-to-support is at least 2:1

If you can't find a logical target that gives you at least 1.5:1 R:R, the setup isn't worth taking. Pass and wait for a better entry.

This is also where position sizing comes in: even with a great R:R, the wrong position size can blow up your account on a single bad trade. R:R tells you whether to take the trade; position size tells you how big to take it.

Common R:R Mistakes

Setting Arbitrary Targets

Picking a target at a round number ($50.00) or "until I'm up 5%" without regard for actual chart levels is backwards. Your target should be set at a logical resistance level first — then you check if the R:R is acceptable. If the natural resistance is at 1:1.2 R:R, the setup is borderline. If natural resistance is at 2.5:1, it's a strong setup.

Moving Your Stop to Improve R:R

If the R:R looks bad, don't solve it by tightening your stop. A tight stop below logical support is a stop that will get hit by normal noise. Set your stop at the level where the trade thesis is invalidated — then check if the R:R is acceptable.

Ignoring Commissions and Slippage

On 166 shares, even $0.01 per share commission each way costs $3.32. On a small account, these add up. Factor commissions into your R:R calculation, especially on smaller positions.

The Bottom Line

Every trade you consider, check the R:R before anything else. If it's below 1.5:1, I need exceptional conviction to take it. If it's below 1:1, I don't take it — period.

Better to wait for the right setup than to grind your account down on marginal ones.
