3 Risk Reward Ratio Calculator Tools, Compared Honestly
Heshan Fernando
Co-founder & COO
You’ve spotted a trade setup and want to check whether the risk-reward ratio actually justifies entering — comparing your entry, stop loss, and take profit levels before committing capital, not after.
Every calculator here computes the core R:R ratio correctly; the differences are in whether it also tells you the minimum win rate needed to be profitable, supports scaling out with multiple take-profit targets, and handles both long and short setups.
How to judge a risk reward ratio calculator tool
Shows the breakeven win rate, not just the ratio. A 1:2 ratio needing only a 33% win rate to break even is a more actionable number than the ratio alone — it tells you whether your actual trading track record supports the setup.
Supports both long and short trades. A calculator that only handles long positions is half as useful if you trade both directions.
Handles scaling out with multiple targets, if that’s your strategy. Professional traders often take partial profits at multiple levels rather than one single take-profit point.
No signup for a quick pre-trade check. Checking a setup before entering is typically a fast, in-the-moment decision.
The comparison
| Tool | Best for | Free tier | Watch out |
|---|---|---|---|
| TradeZella | Long/short support with minimum win rate calculation | Free, no signup for the calculator | Signup promoted for automated trade tracking features |
| Share Predictions | Multiple take-profit targets for scaling out, expected value calculation | Free, no signup | More setup steps than a single-target quick check |
| Capital Companion | Clear R-multiple explanation alongside breakeven win rate | Free, no signup for the calculator | Account creation promoted to save trade plans |
| Risk Reward Ratio Calculator | Long or short trade risk-reward ratio from entry, stop loss, take profit | Free, no signup | No breakeven win rate or minimum win rate output |

TradeZella
TradeZella calculates your risk-to-reward ratio, potential dollar profit and loss, and the minimum win rate needed to be profitable at that ratio, with a position type selector supporting both long and short trades — free to use with no signup required for the calculator itself.
It isn’t for someone who wants to avoid any account prompts at all — the tool encourages registering with TradeZella’s broader platform for automated trade tracking.
Share Predictions
Share Predictions calculates risk-reward ratio and break-even win rate, and specifically supports scaling out with up to three separate take-profit targets each with its own allocation percentage — a strategy used by professional traders to lock in partial profits while letting winners run — plus an expected value calculation per trade based on assumed win rate.
It isn’t for someone who wants the fastest possible single-number check — the multiple-target setup takes more input than a basic one-target calculation.
Capital Companion
Capital Companion calculates your R-multiple (reward per share divided by risk per share) and breakeven win rate using the formula risk ÷ (risk + reward), clearly explaining that a 1:2 setup only needs a 33.3% win rate to break even — free to use without registration.
It isn’t for someone who wants to save trade plans without an account — creating a free account is offered specifically to save your calculation as a trade plan.
Risk Reward Ratio Calculator
Our tool calculates the risk-reward ratio for a long or short trade from your entry, stop loss, and take profit levels — entirely in your browser.
A real limitation: it doesn’t calculate the breakeven or minimum win rate needed for profitability — for that additional context, TradeZella or Capital Companion’s calculators cover more ground.
Which one to pick
If you just need the risk-reward ratio for a long or short setup quickly, use our Risk Reward Ratio Calculator.
If you want to know the minimum win rate your strategy needs to be profitable, use TradeZella or Capital Companion.
If your strategy involves scaling out at multiple take-profit levels, use Share Predictions.
If you want a clear explanation of the R-multiple concept alongside the number, use Capital Companion.

Frequently asked questions
Is there a free risk reward ratio calculator that doesn’t need an account?
Yes. Our Risk Reward Ratio Calculator and all three alternatives here calculate ratios without requiring signup for the core calculator.
What counts as a “good” risk-reward ratio?
A ratio of 1:2 or higher (risking $1 to potentially make $2 or more) is commonly cited as a reasonable baseline for many trading strategies, since it means you can be profitable even with a win rate below 50% — but the “right” ratio genuinely depends on your strategy’s actual historical win rate, not a fixed rule that applies to every setup.
Why does the breakeven win rate matter more than the ratio alone?
The ratio alone doesn’t tell you whether a setup is actually favorable — a 1:1 ratio needs a win rate above 50% to be profitable, while a 1:3 ratio only needs a win rate above 25%. Calculating breakeven win rate (risk ÷ (risk + reward)) tells you the threshold your actual trading performance needs to clear, which is the number that actually determines whether the setup makes sense for your track record, a concept covered in most trading risk management resources like Investopedia’s risk-reward ratio explainer.
Final thought
Don’t stop at the ratio alone — checking the breakeven win rate against your actual historical performance is what tells you whether a setup is genuinely worth taking, not just whether the math looks favorable on paper.
