You risk $50. You make $150. You made +3R.
You risk $50. You lose $50. You lost -1R.
You risk $50. You make $25. You made +0.5R.
That's R. And once you start tracking trades this way, it becomes much easier to compare performance without account size, lot size, and dollar amounts muddying everything up.
The R-Multiple Calculator tells you how much you made or lost relative to the amount you originally risked.

What Does R Mean?
R represents your initial risk on the trade. If you risk $100, then 1R = $100. If you risk $25, then 1R = $25. If you risk $500, then 1R = $500.
The dollar amount changes. The unit doesn't. That's what makes R useful.
The Formula
For a winning trade:
Profit ÷ Initial Risk = R-Multiple
Suppose risk = $75, profit = $150:
150 ÷ 75 = +2R
For a losing trade, loss = $75, initial risk = $75, result = -1R.
If you exit before the full stop and lose $30:
30 ÷ 75 = -0.4R
Why Not Just Track Dollars?
You absolutely should know your dollar results. But dollars don't tell you much about the quality of the trade without knowing how much you risked.
Suppose Trade A makes $500, Trade B makes $200. Trade A looks better. Except:
Trade | Risk | Profit | Result |
A | $500 | $500 | +1R |
B | $50 | $200 | +4R |
Now we have a very different picture.
R Lets You Compare Trades Fairly
Trade | Risk | Profit | Result |
1 | $20 | $60 | +3R |
2 | $100 | $300 | +3R |
3 | $500 | $1,500 | +3R |
Different account sizes. Different dollar amounts. Same trade performance relative to risk. That's the whole point.
R Is Especially Useful When Your Account Grows
Suppose you begin trading with $1,000 and risk 1%. 1R = $10. Later your account reaches $5,000, 1R = $50. Eventually $10,000 account, 1R = $100.
If you only compare dollars, your later trades naturally look much larger. But +2R is still +2R. You can evaluate the method independently from the changing account balance.
R Is Not the Same as Risk Percentage
These are connected but different.
Suppose you risk 1% of your account. That 1% becomes 1R. If the trade makes 2R, you made approximately 2% of the account before considering compounding and trading costs.
If you risk 0.5%, then 1R = 0.5%. A +2R trade represents approximately +1%.
R describes the trade relative to its initial risk. Risk percentage describes what that initial risk represents relative to your account.
R Is Not the Same as Risk-to-Reward Either
Suppose before entering you plan stop = 20 pips, target = 60 pips — planned risk-to-reward 1:3. If price reaches the target: result = +3R.
But suppose you exit early at 30 pips. Actual result: +1.5R.
Your planned reward was 3R. Your realized result was 1.5R. That's an important distinction.
Planned R vs. Realized R
This is something worth tracking.
Suppose planned target = +3R, actual exit = +1.2R. Now ask why. Maybe you intentionally took partial profits. Price reversed. Your trailing stop was hit. You manually exited. Or you panicked because a candle looked at you funny.
The reason matters.
Try the R-Multiple Calculator
Enter your amount risked and profit or loss. The calculator will show your R-multiple. For example:
Risk $100 / Profit $200 = +2R
Risk $100 / Loss $100 = -1R
Risk $100 / Profit $50 = +0.5R
Risk $100 / Loss $50 = -0.5R
Simple. And ridiculously useful.
A Winning Trade Can Be Less Than +1R
Suppose you risk $100 and make $40. Result: +0.4R. That's still a winning trade. Your journal shouldn't automatically classify every winner as +1R or more. Use the actual result.
A Losing Trade Can Be Less Than -1R
Suppose you risk $100 but exit early for -$35. Result: -0.35R. Maybe your setup invalidated before reaching the original stop. Maybe you had a management rule. Whatever the reason, your actual result was -0.35R. Not -1R.
A Losing Trade Can Also Be Worse Than -1R
Suppose your planned risk was $100 but you lose $160. Result: -1.6R. That should get your attention.
Maybe you moved the stop. Slippage occurred. Price gapped. You added to the trade. Or your original risk calculation was wrong. A result below -1R isn't automatically misconduct. But it deserves explanation.
1R Should Be Defined Before the Trade
This is important. Suppose you enter a trade and initially risk $50. The trade loses. Afterward you say "well technically I was willing to lose $100." No. That's not how R works.
Your initial planned risk was $50. That is 1R. R is defined by the risk established when you enter the trade. Not by whatever number makes the journal look nicer afterward.
R Makes Journaling Much Cleaner
Imagine this trade history: +$120, -$40, +$75, -$55, +$300, -$90. What does that tell you? Not much without knowing the risk on each trade.
Now look at: +2R, -1R, +1.5R, -0.5R, +3R, -1R. Much easier. You can immediately see the relationship between wins and losses.
Add Them Together
Using +2R, -1R, +1.5R, -0.5R, +3R, -1R. Total: +4R. Six trades. Average: 4 ÷ 6 = +0.67R per trade.
Now your individual trade results are becoming strategy statistics.
R Makes Expectancy Easier to Calculate
Suppose win rate = 45%, average winner = +2R, average loser = -1R.
Expectancy = (0.45 × 2) − (0.55 × 1) = +0.35R
Now your expectancy isn't tied to a specific account balance. That's why R is so useful for backtesting.
R Makes Profit Factor Easier Too
Suppose your winning trades total +60R, your losing trades total -40R.
Profit factor = 60 ÷ 40 = 1.5
Again, account size doesn't matter. You're evaluating the method relative to its own risk.
R Makes Different Account Sizes Comparable
Trader | Account | Risk | Profit | Result |
Trader A | $500 | $5 | $15 | +3R |
Trader B | $50,000 | $500 | $1,500 | +3R |
One made $15. One made $1,500. But both executed a trade that produced 3 times the amount initially risked. That makes R particularly useful when teaching or comparing strategy results.
R Makes Backtesting More Useful
Suppose you're backtesting historical charts. You don't necessarily need to ask "how much money would I have made?" That requires assumptions about account balance, lot size, compounding, and risk percentage.
Instead, record: Trade 1: +2R, Trade 2: -1R, Trade 3: +3R, Trade 4: -1R, Trade 5: +0.5R. Now you can evaluate the underlying strategy first. Account sizing can come later.
R Helps Separate Strategy From Money Management
Suppose your strategy produces +30R across 100 trades. That's the method. Now decide: what is 1R worth?
If you risk 0.5%, then those R results translate differently than if you risk 1%, or 2%. The strategy generated the same sequence of R. Your risk model determines how aggressively that sequence affects your account.
This Is Important When Compounding
Suppose your account is $1,000, risk 1%, so 1R = $10. You win +2R. Account becomes approximately $1,020. Now 1% risk becomes $10.20. Your next +2R would be worth approximately $20.40.
R remains 2R. The dollar amount changes as the account changes. This lets you separate trade performance from compounding.
R Helps Compare Different Setups
Setup | Avg Winner | Avg Loser |
Setup A | +2.2R | -0.8R |
Setup B | +1.1R | -0.6R |
Which is better? We still need win rate, expectancy, profit factor. But now both setups are expressed in the same unit. That makes the comparison much easier.
Track R by Setup
Maybe your journal eventually shows Setup A: +42R, Setup B: +18R, Setup C: -6R. Interesting. But don't stop there. Calculate average R per trade and expectancy for each. Total R is useful. Context makes it useful-er. Yes, I'm declaring that a word.
Track R by Pair
Maybe EUR/USD: +35R, GBP/USD: +18R, USD/JPY: -4R. Now compare number of trades, average R, expectancy, profit factor. You may begin seeing where your method historically performs best.
Track R by Session
Maybe London: +40R, New York: +15R, Asia: -7R. Again: interesting. But don't immediately conclude Asia is evil. Check the sample. Maybe you only have 12 Asian trades. Data first. Drama later.
Track R by Direction
Maybe long trades: +32R, short trades: +14R. Now calculate average R per trade. Maybe you simply took twice as many longs. Raw totals alone don't tell you everything.
Track R by Rule Adherence
This is one of my favorites.
Trades | Total R | |
Followed the Rules | 100 | +38R |
Broke the Rules | 35 | -14R |
Well. That's irritatingly clear. Sometimes your journal discovers that the strategy isn't your biggest problem.
Use R to Analyze Exits
Suppose your planned target is 3R. Your actual average winner is 1.1R. That's worth investigating.
Maybe your partial-profit strategy intentionally creates that average. Fine. But maybe you're constantly closing trades early. If so, your realized strategy is very different from your planned strategy.
Compare Planned R With MFE
Suppose planned target = 3R, actual result = +1R, maximum favorable excursion = +3.5R. That means price eventually traveled 3.5 times your initial risk in your favor while the trade was open. But you captured 1R.
If this happens repeatedly, your exit strategy deserves investigation.
Compare MAE in R Too
Suppose initial risk = 20 pips = 1R. Price moves 10 pips against you before eventually reaching target. Maximum adverse excursion: -0.5R.
Now collect that across winning trades. Maybe most winners never exceed -0.4R before working. Interesting. That may help you study entry quality or stop placement. Not automatically change it. Study it.
R Can Make Different Stop Sizes Comparable
Trade | Stop | Winner | Result |
A | 10-pip stop | 30-pip winner | +3R |
B | 40-pip stop | 120-pip winner | +3R |
The pip totals are completely different. The performance relative to risk is identical. That's why "I made 120 pips!" isn't enough information to evaluate the trade. How much did you risk to make them?
Same With Losing Trades
Trade | Stop | Loss | Result |
A | 10-pip stop | 10 pips | -1R |
B | 50-pip stop | 50 pips | -1R |
One lost five times as many pips. Both lost the amount they originally planned to risk. From a strategy-performance perspective: -1R and -1R.
Pips and R Answer Different Questions
Pips ask: how far did price move? R asks: how much did I make or lose relative to what I risked?
Suppose Trade A makes 20 pips with a 5-pip stop — result +4R. Trade B makes 50 pips with a 50-pip stop — result +1R.
Trade B caught more pips. Trade A produced more reward relative to its risk. Both measurements are useful. They're just measuring different things.
Dollars, Pips, and R All Belong in the Journal
You don't have to choose one. Record pips, R, and dollars. Each answers something different.
Pips — what did price do?
R — how did the trade perform relative to risk?
Dollars — what happened to the actual account?
Together, you get the full picture.
R Can Help Stop You From Chasing Huge Pip Numbers
A 100-pip trade isn't automatically better than 30 pips. If the first required 100 pips of risk and the second required 10, then Trade 1: +1R, Trade 2: +3R.
The giant pip count isn't nearly as exciting anymore. Which is useful. Because pip bragging is a terrible performance metric.
R Can Also Stop Dollar Amounts From Messing With Your Head
Suppose your account grows. Early trade: +3R = +$30. Later: +1R = +$500. The second trade made much more money. But the first trade produced three times its initial risk.
Separating execution quality from dollar outcome can make reviewing your trading much cleaner.
Use R to Build Your Equity Curve
Instead of plotting dollars, create a cumulative R curve.
Trade 1: +2R (cumulative 2R) → Trade 2: -1R (cumulative 1R) → Trade 3: +3R (cumulative 4R) → Trade 4: -0.5R (cumulative 3.5R)...
Continue across your entire backtest. Now you can see the strategy's performance without position sizing obscuring it.
Drawdown Can Be Measured in R Too
Suppose your cumulative R reaches +30R, then falls to +22R. Drawdown: 8R. Later it reaches +50R, then falls to +39R. Drawdown: 11R. Maximum drawdown: 11R.
Now you have a strategy-level drawdown measure independent of account size.
Losing Streaks Become Easier to Understand
Suppose your standard loss is -1R. Six consecutive full losses: -6R.
If you risk 1% per trade, that sequence has one account-level effect. At 2%, it has another. But the strategy-level event remains: six losses totaling approximately -6R.
Again: strategy behavior, account sizing — separate them.
R Makes Strategy Changes Easier to Evaluate
Suppose Method Version 1: 200 trades, expectancy +0.20R. Method Version 2: 200 trades, expectancy +0.38R.
That's much easier to compare than "Version 1 made $2,840, Version 2 made $6,125." Maybe the account size or risk changed between tests. R removes that noise.

R Is Also Useful for Challenges
Suppose you're tracking account growth. Instead of focusing only on "we made $X," you can report this week: +2R, -1R, +3R, +1.5R. Total: +5.5R.
Now someone with $500 and someone with $10,000 can understand the exact same method results relative to their own risk.
Don't Rewrite R After the Trade
Suppose you originally risked $100. Trade makes $200. That's +2R. You cannot afterward say "well, technically I would have been comfortable risking $200" and call it +1R.
No. Initial risk defines R. This keeps your statistics honest.
What About Moving the Stop to Break Even?
Suppose initial risk = $100 = 1R. Later you move the stop to break even. Your initial R remains $100. If you then make $200, the trade result is +2R.
You don't redefine 1R as zero because you later removed the remaining risk. R is based on the initial risk at entry.
What About Scaling Out?
Suppose 1R = $100. Half the position exits at +1R — that portion contributes $50. The other half exits at +3R — that portion contributes $150.
Total profit: $200. Original risk: $100. Final result: +2R.
This is why your realized R may be very different from the farthest target reached.
What About Scaling In?
This gets more complicated. If you add positions, your total trade risk can change.
Suppose initial risk = $50. Then you add another position with $30 additional risk. Total planned risk becomes $80.
You need to define whether you're treating these as separate trades or one combined trade. Whatever you choose, stay consistent. For a combined position, calculate R from the total defined risk of the combined trade.
Consistency Is More Important Than Fancy Math
Your journal doesn't need a doctoral thesis on R. It needs a clear definition, applied the same way, every time.
If 1R = initial planned loss, then use that definition across backtests, demo trades, live trades, and reviews. Now your statistics actually mean something.

If there's one habit that makes trade analysis dramatically cleaner, it's this: stop judging trades only by dollars or pips. Ask: how much did I make or lose compared with what I was willing to lose?
That's R. And suddenly +$300 doesn't automatically look amazing. -50 pips doesn't automatically look terrible. And a tiny little +20-pip trade might turn out to have been +4R.
Context ruins all the fun. It also makes you a much better analyst.
Educational purposes only. Forex trading involves substantial risk. R-multiple calculations measure trade results relative to defined initial risk and do not predict future performance. Actual account results can differ because of position sizing, trading costs, slippage, execution, scaling, and changing market conditions.
