Risk-Reward Ratio in Forex: How to Calculate It

Why does a winning strategy still lose money?

You have a strategy that wins six trades out of ten. On paper, that looks like a good system. Yet after two months your account is smaller than when you started. The chart did not lie to you, and the strategy did not stop working. The problem is that the wins are small and the losses are large, and nobody checked how the two balance out.

This is the trap that the risk-reward ratio is designed to expose. A trader can be right more often than wrong and still lose money, if each losing trade costs far more than each winning trade earns. Most beginners never measure this. They look at the number of wins, feel encouraged, and miss the fact that the account is shrinking slowly.

What is the risk-reward ratio, in plain words?

The risk-reward ratio compares two numbers. The first is the risk, which is the distance from your entry price to your stop loss. The second is the reward, which is the distance from your entry to your take profit. You measure both in pips, and you divide the reward by the risk.

Suppose you buy EURUSD at 1.0850. Your stop loss sits at 1.0830, which is twenty pips below your entry. Your take profit sits at 1.0890, which is forty pips above. The risk is twenty pips, the reward is forty pips, and the ratio is 40 divided by 20, which is 2. People write this as 1:2. It means you accept one unit of risk to aim for two units of reward.

The ratio is a planning tool. It tells you how the trade is shaped before you enter. It does not tell you whether the trade will work, and it does not tell you how often the trade will win. Those answers come from your strategy and from your results over time.

Why does the ratio matter more than the number of wins?

Think about two traders over ten trades each. The first trader wins six trades, each for twenty pips, and loses four trades, each for twenty pips. The risk and reward are both twenty pips, so the ratio is 1:1. Their net result is six times twenty minus four times twenty, which is forty pips of profit.

The second trader wins six trades, each for ten pips, and loses four trades, each for forty pips. The ratio is 1:0.25, which is poor. Their net result is sixty minus one hundred and sixty, which is a loss of one hundred pips. The second trader won the same number of trades as the first, but lost money because the wins were small and the losses were large.

The lesson is clear. The win rate and the ratio work together. A strategy with a low win rate can still make money if the ratio is high enough, and a strategy with a high win rate can still lose money if the ratio is poor. You need both numbers to judge the system.

How do I calculate the ratio step by step?

Start with the entry price, which is the price where you plan to open the trade. Not the price you see a moment before you click, but the level your rules tell you to enter at. Write it down before you open the position.

Next, set the stop loss. The stop should sit where your idea is wrong, based on the chart structure, such as below a recent swing low for a buy. Do not set the stop based on how much money you want to risk. The dollar amount comes later, when you size the lot.

Then set the take profit. This is where your idea is right, based on a clear level such as a previous high, a resistance zone or a fixed multiple of the stop. Measure the distance to each level in pips, using the pip size for your pair. For most pairs that is the fourth decimal place, and for yen pairs it is the second decimal place.

Finally, divide the reward pips by the risk pips. If the stop is twenty-five pips and the target is seventy-five pips, the ratio is 75 divided by 25, which is 3. Write the ratio in your plan next to the entry, stop and target. If you cannot write a clear ratio, the trade is not ready.

How should I size the lot from the ratio?

The ratio does not set your lot size. Your risk limit does. Suppose your account is five thousand dollars and you risk one percent per trade. That is fifty dollars. If the stop is twenty-five pips and you trade EURUSD, the pip value you need is two dollars per pip (fifty dollars divided by twenty-five pips). A mini lot on EURUSD is about one dollar per pip, so you would use about two mini lots.

This order matters. Set the stop from the chart, set the target from the chart, calculate the ratio, and then size the lot from the dollar limit. Beginners who reverse this order, picking a lot size first and then drawing a stop to fit, usually end up with a stop that is too tight for normal movement or a risk that is larger than the plan.

The risk-reward calculator linked in this guide does the arithmetic for you. Enter the account balance, the risk percentage, the entry, the stop, the target and the pip value. It shows the money at risk, the stop and reward distances in pips, the ratio and the lot size that keeps the loss inside your limit.

What is the break-even win rate for each ratio?

A useful number to know is the break-even win rate. It is the share of trades you need to win, at a given ratio, for the strategy to break even before costs. For a 1:1 ratio, you need to win half your trades. For a 1:2 ratio, you need to win one trade in three. For a 1:3 ratio, you need to win one in four.

The formula is simple. The break-even win rate equals one divided by one plus the ratio. At 1:2, that is one divided by three, which is about thirty-three percent. At 1:1.5, it is one divided by two point five, which is forty percent.

This number lets you judge your strategy without guessing. If your tested win rate is forty-five percent and your ratio is 1:2, your strategy should be comfortably profitable before costs. If your win rate is thirty percent at the same ratio, it is losing money. The break-even figure turns a vague feeling into a clear test.

Remember that spread and commission raise the break-even point. A trade with a three-pip cost needs a little more movement to reach the same net result. Include the cost in your calculation, especially on short-term strategies where the target is only a few pips away.

Does a high ratio always mean a better trade?

No. A very high ratio can come from a stop that is too tight or a target that is too far. If the stop is only five pips below the entry on a volatile pair, normal price movement will probably hit it before the idea has a chance to work. The ratio looks excellent on the screen, but the trade fails for reasons unrelated to the market direction.

A very high target can also be unrealistic. If the nearest real level is twenty pips away and you place the target at one hundred pips, the trade will rarely reach it. The ratio is high, but the trade will almost always close at the stop or at a smaller exit. Plan the target from the market structure, then calculate the ratio, rather than the other way round.

Watch for trades where the ratio drops to fit a picture you like. If you want the setup to look better, you may move the stop closer and call the ratio improved. That is backwards. The stop should sit where the idea is wrong, and the ratio is the result of that decision, not the goal of it.

How do I test a ratio before I trust it?

Testing a ratio means collecting real results over enough trades to see a pattern. Thirty trades is a practical minimum for a first look, and a hundred trades gives a clearer picture. Log each trade with the planned entry, stop, target, planned ratio and the result. Use the journal layout in the demo trading journal linked in this guide if you want a ready-made sheet.

After the sample, calculate your actual win rate and your average win and average loss in pips. Compare the result with the break-even win rate for your planned ratio. If the actual win rate is above the break-even point, the strategy has an edge before costs. If it is below, the strategy is losing money even if individual wins feel exciting.

Test on a demo account first. The purpose is to learn how your strategy behaves, not to chase profit. Once the demo results match your expectations over a reasonable sample, consider a small live position. Keep the risk per trade at the same level you tested, and do not increase size because of a short winning run.

The MT4 and MT5 strategy testers can also help. Both platforms include a testing environment, and the MetaTrader help pages linked in the sources explain how to run a test. Use the tester to check historical ratios, but remember that a backtest is only a guide. Real spreads, slippage and execution can differ from the test.

What does the risk-reward ratio not tell you?

The ratio does not tell you the probability of a win. Two strategies can have the same ratio and very different win rates, and the difference decides whether either of them makes money. The ratio also does not tell you how long a trade will last. A 1:2 trade that takes three days ties up margin for much longer than a 1:2 trade that closes in an hour.

It does not tell you the risk of a losing streak either. Even a good strategy with a positive expectancy can lose five or six trades in a row. If your risk per trade is too large, that streak can damage the account badly. The lot size and risk limit protect you from streaks, not the ratio.

Finally, the ratio does not replace your rules. A trade that fits the ratio but breaks your entry criteria is still a bad trade. Write the rules first, and use the ratio as one of the checks, not as the reason to enter.

How do spread and commission change the real ratio?

The ratio you calculate from chart prices is the gross ratio. Your account pays a cost on every trade, and that cost reduces the net ratio. On a typical account the cost shows up as the spread, which is the gap between the buy and sell prices, and sometimes as a separate commission per lot. Both come out of your result, and both change the break-even point you need to beat.

Take a trade planned at 1:2. The stop is twenty pips and the target is forty pips. Suppose the spread on the pair is two pips and you pay no commission. When the target is hit, you keep forty pips minus the two-pip spread, which is thirty-eight pips. When the stop is hit, you lose twenty pips plus the two-pip spread, which is twenty-two pips. The net ratio is 38 divided by 22, which is about 1:1.73, not 1:2.

Now add a commission equal to three pips per trade. The winning trade keeps thirty-five pips, and the losing trade costs twenty-five pips. The net ratio falls to about 1:1.4. A trade that looked like a comfortable 1:2 on the chart is now below the 1:1.5 minimum many traders set. The cost did not change the chart. It changed the arithmetic of the plan.

This is why you should measure costs before you judge a strategy. Add the spread, and any commission converted into pips, to the risk side and subtract it from the reward side. Then calculate the break-even win rate using the net ratio, not the gross one. The result is a more honest picture of whether the strategy can make money.

Costs also matter more on short-term trades. A scalp with a five-pip target and a two-pip spread gives up forty percent of its reward before the trade starts. A swing trade with a hundred-pip target loses only two percent of its reward to the same spread. Strategies built on small targets need a wide enough target to absorb the cost, or they need a broker with much tighter spreads.

Check the cost directly on your account. Open the market watch window in MT4 or MT5, read the spread for the pair at the time you normally trade, and note whether it widens at rollover or during news. Compare brokers on the spread you actually pay during your trading hours, not on the advertised minimum.

What does a real week of ratios look like?

Numbers in the abstract are easy to agree with. Real trades are messier. Imagine a trader who uses one simple rule: enter on a pullback to a moving average in the direction of the trend, place the stop below the last swing low, and take profit at the next swing high. The trader is testing this on GBPUSD on the one-hour chart, with a five thousand dollar account and a one percent risk limit.

On Monday, the trader sees a pullback that enters at 1.2700. The swing low is at 1.2675, so the stop is twenty-five pips away. The next swing high is at 1.2775, which is seventy-five pips from entry. The ratio is 75 divided by 25, which is 1:3. The risk is fifty dollars, so the lot size works out to about two mini lots. The trade closes at the target, and the result is a win of about one hundred and fifty dollars before costs.

On Tuesday, the trader sees a similar setup. The entry is at 1.2730, the stop is at 1.2710, and the target is at 1.2760. The stop is twenty pips away and the target is thirty pips away, so the ratio is 1:1.5. The trader calculates the lot size from the same fifty dollar limit and places the trade. Price moves against the position, and the stop is hit. The loss is fifty dollars, as planned.

On Wednesday, the trader sees a setup with a stop of forty pips and a target of forty pips. The ratio is 1:1, which is below the trader’s preferred minimum of 1:1.5. The trader skips the trade. Nothing about the chart looked bad, but the rule said no, and the rule is what protects the account over time.

By Friday, the week has three trades taken and one skipped. Two wins and one loss, with the skipped trade left alone. The trader’s written log shows the planned ratio for each trade, the planned dollar risk, and the actual result. That log is what makes the next review useful, because it shows whether the ratio rules were followed and whether they paid off.

The example is simple on purpose. A real week may have more trades, more losses and less clean structure. What matters is the habit: write the ratio before entry, follow the rule, and record the result. The ratio then becomes a check on each decision rather than a number you decide after the trade.

How do news events change the ratio?

Scheduled news such as central bank decisions and employment reports can move a pair many pips in seconds. A stop that looks sensible on a quiet chart can be hit in one candle when news lands. The ratio you planned before the release may no longer match the price you can actually get after it.

This affects two things. First, the spread often widens around news, so your entry and stop may fill further away than planned. Second, the price can gap past your stop, so the loss can be larger than the planned dollar risk. The ratio on paper assumes clean fills, and news rarely gives clean fills.

A simple rule helps. Check the economic calendar before you trade, and either avoid entries close to high-impact releases or reduce the lot size so that a wider stop still keeps the loss inside your limit. The blog index on this site has beginner articles on timing and market movement, and it is a good place to learn how to read the calendar alongside your chart.

Do not widen a stop after a news release to protect a position you already hold. That turns a planned loss into an unplanned one and breaks the ratio you wrote before the trade. If you want to change a plan around news, make the change before the release, while your head is clear, and write it down.

How do I stop chasing a perfect ratio?

Some traders spend more time looking for a perfect ratio than they spend on the chart itself. They move the stop a few pips, change the target, and recalculate until the numbers look good. This is a form of overfitting, where the plan is shaped to fit the past rather than to predict the future.

The fix is to set a rule and keep it. Choose a minimum ratio, such as 1:1.5, and a method for placing stops and targets. Use that method on every trade for a fixed period, then review the results. Only change the method after you have enough trades to judge it, and change one thing at a time.

Remember that a ratio is a measure, not a target. You are not trying to reach a specific number on every trade. You are trying to avoid trades where the reward is too small for the risk. Skipping a trade with a poor ratio is a legitimate decision, and often the most profitable one.

What is the offer in this guide?

The offer is a free Excel calculator. It takes your account balance, risk percentage, entry, stop loss, take profit, pip size and pip value, and works out the rest. You do not need to write formulas yourself, because the calculations are already in place. Only the yellow cells need your input.

Here is what the calculator gives you:

Feature	What it does	Limit
Money at risk	Turns your risk percentage into a dollar figure	Uses the balance you type, so update it after each period
Stop and reward in pips	Measures both distances from your entry	You must enter the pip size for your pair
Risk-reward ratio	Divides reward pips by risk pips	Does not include spread or commission
Lot size	Sizes the position to your dollar limit	Assumes the pip value you enter is correct
Mini-lot count	Shows the same size in mini lots	Rounds nothing, so round down at the broker
Profit if target hit	Estimates the gain before costs	An estimate, not a guarantee of the outcome

The calculator does not choose entries, stops or targets for you. It does not predict whether a trade will win. It does not account for swaps, commission or slippage. If your account is not in dollars, convert the results yourself at the current rate.

It is a planning tool for trades you have already designed. Use it to check the shape of each trade before you enter, and keep your strategy rules in your own written plan.

How do I start using the ratio this week?

Pick one strategy you already know. Write down its entry rule, its stop rule and its target rule. Use the calculator to work out the ratio for the next ten signals you see, and write the number down before each trade. Do not trade them yet if you are still testing.

After ten signals, compare the ratio with your plan. Did the stops sit where the idea was wrong? Did the targets sit at real levels? If the ratio looked good on paper but the targets were unrealistic, adjust the target rule and test again. Keep notes on each change.

Once you have thirty logged demo trades, calculate your win rate and compare it with the break-even rate for your ratio. If the strategy is profitable on paper and the account can handle the risk, you can consider a small live position. Use the smallest lot your broker allows and keep the risk per trade at the level you tested.

Before you test any ratio, make sure you understand pip size and pip value, because both feed the calculation. The pip guide on this site walks through the maths step by step. Brokers also differ in spread and commission, which change the real ratio, so compare them on the best forex brokers page before you choose where to trade. If you plan to automate the stop and target with an expert advisor, the expert advisor directory lists the tools reviewed on this site, and the blog index has more beginner articles on risk.

The risk-reward ratio is one of the simplest tools in trading, and one of the most useful. It turns a vague idea of a good trade into a number you can check. Use it to shape each trade, to size each position and to judge each strategy over time.
