Risk-to-Reward Ratio Explained: What the Numbers Actually Mean

A risk-to-reward ratio compares how much you are willing to lose on a trade with how much you hope to make.

If you are risking $100 to pursue a possible $200 gain, your potential reward is twice your risk.

That is commonly described as a:

1:2 risk-to-reward ratio

The calculation is simple.

Using it well takes more thought.

A good-looking ratio does not automatically make a trade attractive. You also need to consider how often the setup works, where your stop belongs, whether the target is realistic, and how much you are risking across the account.

What Is a Risk-to-Reward Ratio?

The risk-to-reward ratio compares:

Planned Loss ÷ Potential Profit

Suppose you enter a stock at:

$50

Your stop is:

$48

Your target is:

$54

Your planned risk is:

$50 − $48 = $2 per share

Your potential reward is:

$54 − $50 = $4 per share

You are risking $2 to potentially make $4.

That produces:

1:2 risk-to-reward

Another way to say it:

For every $1 of planned risk, you are targeting $2 of potential profit.

Risk-to-Reward vs Reward-to-Risk

You may see the numbers written in either direction.

A trade risking $1 to make $2 can be described as:

1:2 risk-to-reward

or

2:1 reward-to-risk

They describe the same relationship.

To avoid confusion, always check which number represents the loss and which represents the potential gain.

Throughout this article, we will use:

Risk : Reward

So:

1:2 means risking $1 to potentially make $2.

A Simple Example

Suppose your trading account is $20,000.

You decide to risk:

$200 on one trade

Your setup offers a possible:

$600 profit

Risk-to-reward:

$200 : $600

Divide both sides by $200:

1:3

You are risking $1 for a possible $3 return.

That sounds attractive.

But one important question remains:

How likely is the trade to reach the target before it reaches the stop?

The ratio alone cannot answer that.

Why Traders Use Risk-to-Reward Ratios

Risk-to-reward helps you think about the relationship between losses and winners.

Suppose two strategies both win half their trades.

Strategy A

Average loss: $100

Average win: $100

Risk-to-reward: 1:1

Strategy B

Average loss: $100

Average win: $200

Risk-to-reward: 1:2

Over 100 hypothetical trades with a 50 percent win rate:

Strategy A

50 wins × $100 = $5,000

50 losses × $100 = −$5,000

Result before costs:

$0

Strategy B

50 wins × $200 = $10,000

50 losses × $100 = −$5,000

Result before costs:

+$5,000

The larger average winner changes the economics of the strategy.

A Higher Ratio Can Support a Lower Win Rate

You do not necessarily need to win most of your trades.

Suppose you risk $100 to make $300.

That is:

1:3

Now imagine 10 trades:

3 winners × $300 = +$900

7 losers × $100 = −$700

Result:

+$200 before costs

You lost 70 percent of the trades.

The strategy still produced a positive hypothetical result because the winners were much larger than the losses.

This is why win rate and payoff size need to be studied together.

Break-Even Win Rate

You can estimate the minimum win rate needed to break even before trading costs.

A simple formula is:

Break-Even Win Rate = Risk ÷ (Risk + Reward)

1:1 Risk-to-Reward

1 ÷ (1 + 1) = 50%

You need to win about half your trades to break even before costs.

1:2 Risk-to-Reward

1 ÷ (1 + 2) = 33.3%

1:3 Risk-to-Reward

1 ÷ (1 + 3) = 25%

1:4 Risk-to-Reward

1 ÷ (1 + 4) = 20%

A larger potential reward lowers the theoretical break-even win rate.

Reality is less tidy because trading costs, slippage, partial exits, gaps, and inconsistent execution affect results.

Quick Break-Even Table

*Before commissions, spreads, slippage, taxes, and other trading costs.

This table shows why a high win rate is not the only path to profitability.

It also shows why a strategy with very small winners needs to be right more often.

Risk-to-Reward Does Not Tell You Probability

This is where many traders get caught.

Imagine two trades.

Trade A

Risk: $100
Potential reward: $500
Ratio: 1:5

But the target is extremely far away and historically gets reached only 10 percent of the time.

Trade B

Risk: $100
Potential reward: $180
Ratio: 1:1.8

The target is realistic and the setup succeeds much more frequently.

Trade A has the better-looking ratio.

That does not automatically make it the better trade.

You need both:

payoff

and

probability

Expectancy Connects the Two

Expectancy estimates how much a strategy may make or lose on average across many trades.

A simplified formula is:

Expectancy = (Win Rate × Average Win) − (Loss Rate × Average Loss)

Suppose a strategy has:

Win rate: 45%

Average winner: 2R

Loss rate: 55%

Average loser: 1R

Expectancy:

(0.45 × 2R) − (0.55 × 1R)

0.90R − 0.55R = +0.35R

The theoretical expectancy is:

+0.35R per trade

That does not mean every trade produces 0.35R.

It means that across a sufficiently large sample, the average could move toward that figure if the underlying statistics remain stable.

What Is R?

R is a convenient way to express trading risk.

If your planned risk on a trade is:

$150

then:

1R = $150

If you lose $150:

−1R

If you make $300:

+2R

If you make $450:

+3R

This makes it easier to compare trades across different account sizes and position values.

A $500 profit sounds good.

A +0.5R profit tells you much more if the trade originally risked $1,000.

How to Calculate Risk-to-Reward Before a Trade

Suppose you want to buy at:

$80

Your logical stop is:

$76

Your target is:

$90

Step 1: Calculate Risk

$80 − $76 = $4

Step 2: Calculate Potential Reward

$90 − $80 = $10

Step 3: Compare Them

$4 : $10

Divide both by $4:

1 : 2.5

Your planned risk-to-reward ratio is:

1:2.5

If you risk $200 in total, the corresponding theoretical target profit would be:

$500

The Target Needs to Make Sense

A common mistake is choosing a target purely to create an attractive ratio.

Suppose a stock trades at $40.

Your stop is $39.

You want a 1:5 setup, so you put your target at $45.

But the stock has major resistance at $41.50 and rarely moves more than $1 in a typical session.

The spreadsheet says 1:5.

The market structure may say something else.

Targets should reflect realistic price behavior, not a ratio you want to see.

Start With the Trade Structure

A cleaner process is:

1. Identify your entry.
2. Decide where the setup becomes invalid.
3. Identify a realistic target or exit method.
4. Calculate the resulting ratio.
5. Decide whether the trade fits your strategy.

Do not start with:

“I only take 1:3 trades.”

Then manipulate the stop and target until every setup qualifies.

Let the market structure produce the ratio.

Stops Need to Be Logical Too

Suppose you buy at $100.

A meaningful technical level sits at $94.

You want a better ratio, so you place the stop at $99.

Now you are risking only $1.

Your target at $104 creates a beautiful:

1:4 ratio

But normal price noise may repeatedly stop you out before the setup has a chance to work.

The ratio improved.

The trade logic became weaker.

Your stop should reflect where your trade thesis fails.

Position size can then adjust to keep account risk under control.

Position Sizing and Risk-to-Reward Work Together

Suppose you have:

Account size: $25,000

Maximum risk per trade: 0.8%

Maximum dollar risk:

$25,000 × 0.8% = $200

Your trade has:

Entry: $60

Stop: $58

Target: $66

Risk per share:

$2

Position size:

$200 ÷ $2 = 100 shares

Potential reward per share:

$6

Potential profit at target:

100 × $6 = $600

You are risking approximately $200 for a theoretical $600 reward.

Risk-to-reward:

1:3

This ties the ratio back to actual account risk.

Your Planned Ratio May Not Be Your Actual Ratio

Suppose you plan:

−1R stop

and

+3R target

That gives you a theoretical 1:3 ratio.

Then you repeatedly:

• take profits early at +1R
• let losses slip to −1.3R
• move targets closer
• move stops farther away

Your actual trading statistics might end up looking like:

Average winner: +1.1R

Average loser: −1.25R

That is very different from the strategy you thought you were trading.

Track actual results.

Slippage Can Reduce Your Ratio

You enter at $50.

Your stop is $48.

Your target is $54.

Planned ratio:

Risk: $2

Reward: $4

1:2

Then the stop triggers during a fast decline and your actual execution occurs at $47.50.

Your loss becomes:

$2.50 per share

Your planned $2 risk was not your actual risk.

FINRA notes that once a stop order is triggered, execution may occur significantly away from the stop price during volatile markets.

Investor.gov also explains that a standard stop order becomes a market order after the stop price is reached, so the execution price is not guaranteed.

Price Gaps Can Distort the Ratio Further

Suppose you hold a stock overnight.

Entry:

$100

Stop:

$95

Target:

$110

Planned ratio:

1:2

Unexpected company news arrives after the market closes.

The stock opens the next morning at:

$85

Your planned $5-per-share loss could become roughly $15 per share if you exit near the opening price.

The original ratio no longer describes what happened.

This is one reason event risk matters.

Leverage Changes the Dollar Impact

Leverage does not improve the quality of your risk-to-reward ratio.

It simply increases exposure.

A 1:2 setup remains a 1:2 setup whether you risk:

$100 to make $200

or

$5,000 to make $10,000

The consequences to your account are very different.

Investor.gov warns that margin can magnify losses and can even result in losses exceeding the amount initially invested.

Do not use an attractive ratio as justification for excessive leverage.

High Win Rate, Poor Risk-to-Reward

Consider a hypothetical trader with:

Win rate: 80%

Average winner: +$50

Average loser: −$300

Over 10 trades:

8 winners:

8 × $50 = +$400

2 losers:

2 × $300 = −$600

Result:

−$200

The trader was right 80 percent of the time.

The strategy still lost money.

Being right often can feel good.

It is not the same as having positive expectancy.

Low Win Rate, Stronger Payoff

Now consider:

Win rate: 35%

Average winner: +$400

Average loser: −$100

Over 20 trades:

7 winners:

7 × $400 = +$2,800

13 losses:

13 × $100 = −$1,300

Hypothetical result:

+$1,500 before costs

The trader loses more frequently than they win.

The winners compensate.

Different strategies can succeed with very different win rates.

Why 1:2 Is Not a Magic Number

You will often hear traders say they only take trades offering at least 1:2.

That can be a useful personal rule.

It is not a universal requirement.

A strategy with a very high win rate may work with a smaller average reward.

Another strategy may require 1:3, 1:4, or more because its win rate is much lower.

The relevant question is:

Does the combination of win rate, average win, average loss, and trading costs produce positive expectancy over a meaningful sample?

The ratio is one part of the answer.

Trailing Stops Change the Final Ratio

You do not always need a fixed profit target.

Some traders use trailing exits.

Suppose you initially risk 1R.

Instead of closing automatically at +2R, you trail the stop as the trade develops.

One winner might produce:

+0.8R

Another:

+2.4R

Another:

+6R

In this type of strategy, your average realized reward matters more than a fixed target printed before the trade.

Keep good records.

Scaling Out Changes the Math Too

Suppose you buy 200 shares.

At +1R, you sell half.

At +3R, you sell the remaining half.

Your average reward is not +3R.

Ignoring costs:

First half:

100 shares × +1R

Second half:

100 shares × +3R

Average across the full original position:

+2R

Partial exits change the realized risk-to-reward.

Account for them when reviewing the strategy.

Moving to Break-Even Is Not Free

Some traders move their stop to the entry price as soon as a trade moves slightly in their favor.

This can reduce certain losses.

It can also turn trades that needed normal room to fluctuate into premature exits.

Suppose many trades move +0.7R, pull back to the entry, then eventually reach +3R.

A break-even rule could remove you before the larger move.

Test the rule rather than assuming it improves risk management.

Risk-to-Reward Should Reflect Trading Costs

Suppose you trade very short-term setups targeting tiny movements.

Potential profit:

$50

Potential loss:

$40

That looks slightly favorable.

But now include:

• spreads
• commissions where applicable
• slippage
• exchange or regulatory fees
• borrowing costs where relevant

Your effective reward may shrink while the loss remains similar.

Small-edge strategies are particularly sensitive to trading friction.

Use net results when evaluating performance.

Keep a Record of Planned and Realized Ratios

Your trading journal should track both.

For example:

After 50 or 100 trades, you can compare what you planned with what you actually achieved.

You may find that your supposed 1:3 strategy produces average winners of only 1.4R.

That is useful information.

Look at Average Win and Average Loss

Instead of obsessing over each individual ratio, calculate:

Average winning trade

and

Average losing trade

Suppose your journal shows:

Average winner: +1.9R

Average loser: −0.9R

Your realized reward relative to risk is a little better than 2:1.

Now combine that with your actual win rate.

That gives you a much clearer view of whether the strategy has worked historically.

One Large Loss Can Distort Everything

Imagine 20 trades.

You carefully keep every loss near −1R.

Then on trade 21, you refuse to exit and lose:

−8R

That one trade can erase several good winners.

This is why discipline around losses matters so much.

A strategy designed around small losses stops behaving as designed when you allow occasional huge losses.

The risk-to-reward model assumes you respect the risk side.

Do Not Change the Target Because You Are Greedy

Your target is $105.

The price reaches $104.80.

You decide $105 is no longer enough.

You move the target to $110.

The market reverses.

You eventually exit at $101.

Changing exits can be valid if your strategy specifically allows it.

Doing it because the trade is making money can quietly damage consistency.

Write the rules first.

Do Not Move the Stop Because You Are Afraid to Lose

The opposite problem happens when a trade moves against you.

Entry:

$50

Stop:

$48

Price reaches:

$48.20

You move the stop to:

$46

Your original risk was $2.

It is now $4.

A planned 1:2 setup may instantly become something closer to 1:1.

You changed the trade’s economics because you did not want to take the planned loss.

Evaluate Risk Across All Open Trades

Suppose you have four positions.

Each risks:

1% of your account

Each offers:

1:3

Individually, the setups look reasonable.

But if all four are technology stocks, a broad sector decline could hit them at the same time.

Your practical risk may be closer to one large concentrated position.

Risk-to-reward calculations should sit inside a broader portfolio risk plan.

A Practical Trade Example

Suppose your account is:

$40,000

You risk:

0.5% per trade

Dollar risk:

$200

You identify:

Entry: $72

Stop: $70

Target: $77

Risk per share:

$2

Potential reward per share:

$5

Risk-to-reward:

1:2.5

Position size:

$200 ÷ $2 = 100 shares

Potential planned loss:

100 × $2 = $200

Potential target profit:

100 × $5 = $500

Now the important questions begin.

Does $70 represent a logical invalidation level?

Is $77 a realistic target based on market structure?

What percentage of similar setups historically reaches that target?

How much slippage do you normally experience?

What other positions are open?

Those questions determine whether the 1:2.5 ratio means anything useful.

A Simple Risk-to-Reward Checklist

Before entering a trade, ask:

1. Where is my entry?
2. Where does the setup become invalid?
3. What is my planned loss per share or unit?
4. Where is the realistic profit target?
5. What is the resulting risk-to-reward ratio?
6. What win rate has this type of setup produced historically?
7. What is the strategy’s expectancy?
8. Could slippage or a price gap make my loss larger?
9. Does the position size fit my account risk limit?
10. Am I choosing the target because the market supports it or because I want a prettier ratio?

If the ratio only looks good because you forced the numbers, it is not useful.

The Bottom Line

Risk-to-reward compares the amount you plan to lose with the amount you could potentially make.

A 1:2 trade risks $1 for a possible $2.

A 1:3 trade risks $1 for a possible $3.

Larger potential rewards can allow a strategy to remain profitable with a lower win rate.

But the ratio never tells you the probability of success.

That is the part many traders miss.

Combine risk-to-reward with your actual win rate, average win, average loss, position size, trading costs, and historical expectancy.

Keep your stop logical.

Keep your target realistic.

Then track what actually happens.

A beautiful ratio on paper means very little if your trading behavior produces something completely different.
