Risk/Reward Ratio Calculator
Set the entry price, stop price and target price to see the reward to risk ratio for the combination of those prices. Then you'll also get how high your win percentage needs to be to break even with the given strategy (the missing piece from the majority of calculators) as well as what your expectation per trade is if your win percent is your actual win percent. The ratio is a simple calculation. The breakeven win rate is the important number that shows whether or not a specific trade is worth putting on.

What the risk/reward ratio actually tells you
Risk/Reward is a measure of the distance from where you enter into the trade to the potential Stop and also to the potential Target. What distance is there in relation to the stop, and what distance in relation to the target? To risk two points to win four (which I've previously called a 2:1) you're giving up a 2:1 setup on whatever the market is. That single number tells you how many times you can lose and still be ahead, that's why this is important.
Traders quote ratios like 1:2 or 1:3 as if the bigger number is automatically better, but a ratio on its own says nothing about profit. A gorgeous 5:1 target the market reaches once in a blue moon loses money; a plain 1:1 you hit six times out of ten prints it. The ratio only means something sitting next to a win rate, and that pairing is what this page is built around.
The formula
reward : risk = |target − entry| ÷ |entry − stop|
breakeven win rate = 1 ÷ (1 + reward:risk)
expectancy (R) = win% × reward:risk − (1 − win%)
The ratio of entry to stop to target in terms of risk/reward is the same as your entry to your stop, which has no relation to your target. So if you enter at 100 with a stop at 98 and a target at 104 then you are risking 2 to make 4 - or a 2:1 reward-to-risk. Next comes the number that really matters, the break even win rate: 1 ÷ (1+2)= 33.3%. As long as you have this number and the set up for profit prior to expenses, then it will be profitable prior to costs; if not then it will bleed regardless of how good each individual trade appears on the chart.
Your true win rate matches up with your expectancy. Since your real win rate at this 2:1 setup is 45%, then the expectancy can be calculated as follows: .45(2) -.55 = +0.35R per trade; i.e., if you are risking one unit, you will take in about one-third of that on average over many trades. The compound interest like factor of that number (not just individual wins), is what causes accounts to grow. A great ratio may look good on paper, but if the win rate is below the break-even point, there will be negative expectancy and mathematically lose money over time.
What counts as a good ratio
There is no single good ratio, only a ratio that fits how often your strategy actually wins. Every ratio comes with a win rate you have to beat:
| Reward : risk | Break-even win rate |
|---|---|
| 1 : 1 | 50% |
| 1.5 : 1 | 40% |
| 2 : 1 | 33.3% |
| 3 : 1 | 25% |
| 4 : 1 | 20% |
Read it as a trade-off, not a target. A higher ratio buys you a lower required win rate, which is why trend and breakout traders happily take a run of small losses waiting for the occasional 3:1 or 4:1 winner. Mean-reversion and scalping strategies win far more often but at 1:1 or worse, and they clear their higher breakeven because the hit rate is there to back it up. The honest question is never "what is the best risk/reward ratio" in the abstract; it is whether your own record beats the breakeven your ratio implies.
The same maths on any market
The arithmetic does not change with the asset, only what a point of distance is worth. On a stock, entry $50.00, stop $49.00, target $53.00 is risking $1 to make $3, a 3:1 with a 25% breakeven. In forex, entry 1.1000, stop 1.0970, target 1.1060 is 30 pips of risk against 60 of reward, a clean 2:1. On a crypto perp or a futures contract the ratio reads the same way; leverage changes the cash at stake and the liquidation maths, not the reward-to-risk itself. Work the ratio from price levels first, then hand the risk in points to the position size calculator to turn it into a position size.
You do not need TradingView or a spreadsheet for this
You may create the ratio of this trading view chart using the long position tool or by building the formula for excel in just one min; Both are good ways. The most commonly overlooked part of creating a ratio (and also the most important) is finding the breakeven win rate and expectancy. Therefore, after you have created a 3:1 ratio box, you will find it difficult to determine if your strategy has met the required 25% threshold. This application works solely within your web browser, creates a link that allows you to easily share your setups, and provides the three essential pieces of information to make a decision about using a ratio, including the ratio itself, the breakeven point, and the per trade expectancy.
Where it fits with your other tools
A ratio is a per-trade number; what a positive edge does over hundreds of trades, and how badly variance can bite before it pays off, is what the risk of ruin simulator shows, since the same edge sized too aggressively can still blow up first. Once the risk is set in price terms, the position size calculator turns your stop distance into the exact size for a fixed percentage of account, and the profit & loss calculator shows what the target and stop are each worth in cash.
The honest limits
The ratio and the breakeven win rate are exact; they are fixed by where you put your stop and target. Everything downstream leans on inputs only you can judge. The win rate is your estimate, and it is only as honest as your trade record, a hopeful number in makes an encouraging number out. The maths also assumes every loss is a clean −1R and every win a clean +R, when real fills slip, stops gap, and you sometimes take partial profit, all of which blur the edges. And it ignores spread and commission, which lift the true breakeven a little above the figure shown, so leave yourself a margin rather than trading a setup that only just clears it.
Frequently asked questions
- What does a 1:2 or 1:3 risk/reward ratio mean?
- It is the same number written the other way round. 1:2 means one unit of risk for two of reward, which this page calls 2:1, and it carries a 33.3% breakeven win rate. 1:3 is one to three (3:1 here), breakeven 25%. The order and the punctuation vary between platforms and traders; the arithmetic does not. Enter your actual entry, stop and target and the calculator reads the ratio for you either way, so you never have to worry which convention a chart is using.
- What reward-to-risk ratio should I aim for?
- There isn't a single answer, since the ratio itself has to be compared to your winning percentage. A 3:1 or a 1:1 will likely have the same expectation, as long as you are winning at 25% or 60%, respectively. The most important thing you can learn about ratios is what is called "breakeven" - that's how often you need to win in order to make money from an investment using that ratio. After that, you should be honest with yourself on if your system is better than your breakeven. The higher ratio gives you a lower required win rate. That is why many Trend Traders are happy to lose frequently small amounts in exchange for occasionally larger wins.
- How is breakeven win rate calculated?
- The breakeven win rate is equal to 1 divided by (1 plus reward to risk). This means if your reward to risk ratio is 1:1 you will have to win more than half of all trades, in order for the strategy to make money. If you are trading 2:1 (reward:risk) then you would have to win more than one third of all trades. If you are using 3:1 then more than a quarter. Less than these numbers, you lose money with each trade. More than these number you gain money with each trade, until there is cost involved. The spread or commission from your broker pushes this "breakeven" just a bit higher, therefore always try to include some room.
- What is expectancy?
- The average profit or loss per trade, measured in units of your risk (R). Expectancy = (win rate × reward) - (loss rate × 1). A positive number means a profitable edge over many trades; +0.3R means you net about 0.3 times your per-trade risk on average. Expectancy, not win rate, is what actually grows an account, a 40% win rate at 2:1 (expectancy +0.2R) beats a 60% win rate at 0.5:1 (expectancy -0.1R).
- Does a good ratio guarantee profit?
- No. The ratio is set by where you place your stop and target, but the market decides how often price reaches the target before the stop. A tempting 5:1 setup is worthless if price almost never travels that far in your favour first. Ratio and realistic win rate have to be judged together, which is exactly what expectancy does, and why this tool asks for both.
- Can I use it for options or crypto trades?
- For everything that has an obvious entry point, exit & target price-wise (stocks, forex, futures, crypto spot or perps) you can take your ratios directly from those price points. The math to determine how much money you will make for each dollar of risk taken is identical. It's the leverage that changes how much of your account is put at risk with every dollar you get back. Options are different. A defined risk trade can be thought of as maximum loss vs. potential profit. But the pay-off curve for options changes over time and with changes in volatility. So model it using your options profit calculator instead of trying to find a single ratio based off a price.
Method and limitations
All of your calculations using input from you will be performed solely by pure arithmetic on your inputs and in your browser. There will be no data retrieved or transmitted out of this page with anything that you have typed. The ratio and breakeven win rate are always calculated exactly. Expectancy is determined based upon the win rate entered (which should reflect your actual historical trade records) and does NOT take into account spreads/commissions etc., which would increase a trader's actual breakeven point somewhat.
