Stock Risk–Reward Calculator
Plan entries, stops, targets and size your trade from account risk. Animated R:R gauge, breakeven win-rate, fees/slippage, and expectancy — in one view.

Direction flips how stop/target deltas are interpreted.
Many traders use ~1–2%.
e.g., 1, 25, 100…

Tip: Use 1R / 2R / 3R to quickly set a target that’s a clean multiple of your stop distance. Fees update the breakeven price so you can see where costs start to matter.
How to use this calculator
- Pick Long/Short, then set Entry, Stop, Target. You’ll see risk/share, reward/share and the R:R ratio.
- Size by shares or toggle size from risk % to use account-based risk. Round to a lot size if needed.
- Add fees/slippage to update breakeven price and net P/L.
- Use Win-rate % to estimate expectancy (average P/L per trade over time).
Notes & limitations
- Gaps, borrow costs and fills can differ from assumptions — stress test wider stops and higher slippage.
- R:R doesn’t predict any one outcome; it helps compare setups. Pair with process & risk rules.
- Education only — not financial advice.

Expectancy ≈ Win% × NetReward − (1 − Win%) × NetRisk. This is an average over a series of trades (variance can be large).
