Understanding Risk/Reward in Trading

What is Risk/Reward Ratio?

The risk/reward ratio measures the potential profit of a trade against its potential loss. It helps traders decide whether a trade is worth taking before entering a position.

For example, if you buy a stock at , set a stop loss at and a target at , your risk is per share and your reward is per share. The risk/reward ratio is 2:1.

A higher ratio means you stand to gain more relative to what you risk. Most professional traders aim for a minimum of 2:1 on every trade.

How to Use This Calculator
  1. Enter your planned entry price.
  2. Set your stop loss — the price at which you will exit to limit losses.
  3. Set your take profit target — the price at which you will lock in gains.
  4. Enter the number of shares you plan to buy.
  5. Optionally enter your total portfolio value and estimated win probability to see position size % and expected value.
What is a Good Risk/Reward Ratio?

A good risk/reward ratio depends on your strategy and win rate, but general guidelines are:

≥ 2:1

Strong Trade

1 - 2:1

Acceptable

< 1:1

Poor / Avoid

Even with a lower win rate, a high risk/reward ratio can produce positive expected value over many trades.

Position Sizing Explained

Position sizing is the process of determining how many shares to buy so that a single losing trade does not damage your overall portfolio.

A common rule is the 1% rule: never risk more than 1% of your portfolio on any single trade. If your portfolio is ,000 and your stop loss is away from entry, you should buy no more than 200 shares (,000 total risk = 1% of portfolio).

Break-Even and Expected Value

Break-even price is the price at which a trade neither makes nor loses money. In this calculator it is shown as your entry price for simplicity (commissions and slippage can be added for precision).

Expected Value (EV) tells you the average profit or loss you can expect from a trade if you repeat it many times. It is calculated as:

EV = (Win% × Total Reward) − (Loss% × Total Risk)

A positive EV means the trade is statistically profitable over the long run, even if individual trades may win or lose.

Example Trade Walkthrough

Let's say you want to trade AAPL with the following setup:

  • Entry Price:
  • Stop Loss: (risk per share)
  • Take Profit: (reward per share)
  • Shares: 100
  • Portfolio: ,000

The risk/reward ratio is 2:1, total risk is , position size is 36% of portfolio, and with a 50% win probability the expected value is per trade.

This is a simplified example for educational purposes. Actual trading involves commissions, slippage, and market risk.
