Summary
Calculate the risk/reward ratio for any trade by entering your entry price, stop loss level, and take profit target. The tool shows risk per share, reward per share, the R:R ratio, the minimum win rate needed to break even, and the expected value of the trade — all client-side with no data sent to any server.
How it works
- Enter your trade entry price.
- Enter your stop loss price (the level where you exit if the trade moves against you).
- Enter your take profit price (the target level where you plan to exit with a gain).
- Optionally enter the number of shares or units to see dollar amounts.
- Results update instantly: risk amount, reward amount, R:R ratio, break-even win rate, and expected value.
Use cases
- Screen trades before entering — only take setups with a ratio of 2:1 or better.
- Calculate how often you need to win to be profitable at your current R:R.
- Size positions based on the dollar risk per share.
- Compare multiple trade setups side-by-side to choose the most favorable.
