The risk-reward ratio compares how far a trade could move against you with how far it could move in your favour, based on the exit levels you plan. It is a simple planning tool, and it is often misunderstood. This guide explains the risk reward ratio in forex, shows how to calculate it, and explains why the ratio alone says nothing about whether a trade is a good idea.

What the risk reward ratio in forex measures
Every planned trade has three levels: an entry, a stop where you would exit if wrong, and a target where you would exit if right. The distance from entry to stop is the planned risk. The distance from entry to target is the planned reward. The ratio compares the two.
The ratio is a description of your plan, not of the market. It tells you how your chosen exit levels relate to each other. It does not tell you how likely either level is to be reached, and it does not account for what happens if prices move past a level before your order is filled.
Why traders use it
Writing the ratio down forces you to decide both exits before entering. That makes it harder to move a stop after the fact or to close a position early without a reason. Used this way, the ratio supports discipline rather than prediction.
How to calculate the ratio
The calculation uses distances, so you can measure in pips or in price. The units cancel out as long as you use the same unit for both.
Risk-reward ratio = distance from entry to target ÷ distance from entry to stop
Some people write the ratio the other way round, as risk to reward. Neither convention is wrong, but mixing them causes confusion. Pick one, label it clearly in your notes, and use it consistently.
Measuring distances correctly
Measure both distances from the same entry level, and count pips from the correct decimal for the pair. Remember that you buy at the ask and sell at the bid, as OANDA’s bid-and-ask help page explains. So the spread affects where your entry actually sits and therefore both distances.
Adding costs
A ratio based on price alone ignores spreads, commissions and financing charges. To get a more realistic picture, add expected costs to the risk side and subtract them from the reward side. Our fees and accounts guides explain where to find these costs for your account.
Why the ratio alone is not enough
A high ratio can look attractive, but it is only half of the picture. A distant target with a close stop produces a large ratio, yet a distant target may be reached less often. A close target with a distant stop produces a small ratio, yet it may be reached more often. The ratio does not tell you which situation you are in.
Understanding that trade-off requires a second number: how often your planned targets are reached compared with your stops. That number can only come from your own records over many trades, and even then it describes the past rather than the future. A forex trading journal is the natural place to collect it.
Ratio and win rate together
Ratio and win rate interact. A plan with a high ratio can still lose money overall if targets are rarely reached. A plan with a low ratio can still lose money if the occasional loss is larger than the many small gains. Looking at either number on its own gives an incomplete picture.
Using the risk reward ratio in forex trade plans
The ratio fits naturally into a written plan alongside position size. A practical sequence looks like this:
- Decide the reason for the trade in one or two sentences.
- Choose the stop level based on where the idea would be wrong.
- Choose the target level based on where you would take the result.
- Measure both distances from the same entry.
- Calculate the ratio and write it down with its convention.
- Calculate position size from your planned maximum loss and the stop distance.
- Note expected costs and how they change the ratio.
Our guide on how to calculate position size in forex explains step six in more detail. The key point is that the stop is chosen for a reason first, and the size follows from it. The ratio is then a check on the plan, not the starting point.
Do not move levels to fit a ratio
It is tempting to push a target further away or pull a stop closer just to reach a preferred ratio. Doing so changes the idea behind the trade without a new reason. If the levels that make sense do not produce a ratio you are comfortable with, that is a reason to reconsider the trade rather than adjust the numbers.
What the ratio cannot protect you from
A planned stop is an instruction, not a guarantee. Prices can move past a level quickly, especially around news or after a weekend close, and the executed price may differ from the planned one. Read your provider’s execution terms and any information about guaranteed stop options before relying on a planned loss figure.
The CFTC’s advisory on eight things to know before trading forex reminds customers that a dealer controls its trading platform, including the prices you see. Keeping your own records of planned and executed levels lets you compare them over time.
Leverage adds another layer. ASIC’s Moneysmart forex guide explains the risks of leveraged currency trading for retail investors. A tidy ratio does not change those risks.
Reviewing ratios in your records
After a series of trades, compare the ratios you planned with what actually happened. Did exits occur at your planned levels, or did execution differ? Did you follow the plan, or did you close early or move a stop? These questions are about process, and they are often more useful than the ratio itself.
Avoid drawing firm conclusions from a short record. A handful of trades can look very different from a longer series. Treat any pattern you see as a question to keep watching rather than a rule.
Common risk-reward mistakes
- Treating a high ratio as a good trade. The ratio says nothing about likelihood.
- Mixing conventions. Label whether you write reward to risk or risk to reward.
- Ignoring the spread. Entry depends on bid or ask, which shifts both distances.
- Leaving out costs. Costs reduce reward and add to risk.
- Moving levels to hit a number. Change levels only for a new reason.
- Assuming stops are guaranteed. Execution can differ from the planned level.

Planning tools only matter if the provider is legitimate. In the US, the NFA’s BASIC database holds registration information for retail forex firms. Our broker safety guides explain how to match a provider to an official record before you open an account.
FAQ
How do I calculate a risk reward ratio in forex?
Divide the distance from entry to target by the distance from entry to stop, using the same unit for both.
Is a higher ratio always better?
No. A higher ratio may come with targets that are reached less often. The ratio alone does not show likelihood.
Does a good ratio make a trade safe?
No. It describes your planned exits only. Forex trading still carries substantial risk.
