Risk Reward Calculator

What is a Risk Reward Calculator?

A risk reward calculator is an essential trade planning tool designed to compare the potential loss (risk) of a trade to its potential gain (reward). By defining your entry, target, and stop loss prices, the calculator solves for the Risk-to-Reward Ratio (e.g., 1:2.50) and provides the critical break-even win rate required for long-term survival.

Professional traders use risk-reward ratios to ensure that their winning trades are significantly larger than their losing trades, making profitability possible even with a win rate below 50%.

How to Use the Risk Reward Calculator

Our high-fidelity trading ratio solver maps your trade parameters:

1. Buy Entry Price (₹): Specify the price at which you intend to buy the stock.
2. Profit Target Price (₹): Set the technical price level where you plan to exit with a profit.
3. Stop Loss Exit Price (₹): Set the protective invalidation level where you will cut your loss.
4. Number of Shares: Input the size of your position to calculate absolute money values.
5. Analyze the Trade Profile: Check the risk-to-reward ratio, absolute profit potential vs. absolute risk, and the break-even win rate.
6. Trade Zone Map: The visual slider depicts your risk zone vs. reward zone relative to your entry price.

Mathematics & Win-Rate Probability Formulas

The calculator computes the ratio and required break-even win rate using:

Risk Per Share = Entry Price - Stop Loss Price

Reward Per Share = Target Price - Entry Price

Reward-to-Risk Ratio = Reward Per Share / Risk Per Share

Break-Even Win Rate = (1 / (1 + Reward-to-Risk Ratio)) * 100

For example, if your entry is at ₹100, Stop Loss is at ₹90 (Risk = ₹10), and Target is at ₹130 (Reward = ₹30):

• Ratio = ₹30 / ₹10 = 3.0 (written as 1 : 3.00)
• Break-Even Win Rate = (1 / (1 + 3)) * 100 = 25%
• This means you only need to win 25% of your trades to break even over time. If your strategy wins 40% of the time, this ratio ensures you are highly profitable.

Frequently Asked Questions (FAQs)

What is a good risk-reward ratio for day trading?

A minimum risk-reward ratio of 1:2 is widely considered standard. This means your potential profit is twice as large as your potential loss, allowing you to remain profitable even if you lose 60% of your trades.

How does the break-even win rate affect my psychology?

Knowing that a high risk-reward ratio (like 1:3) requires a very low win rate (only 25%) to break even takes massive pressure off your trading psychology. You no longer feel the need to be "right" on every single trade to make consistent income.
