Risk:Reward Calculator Guide

Let's figure out how to use this thing!



Read the disclaimer at the bottom of the webpage. Nothing on this page is trading advice. Please do your own research, risk:reward analysis, due-diligence, etc.

Based on your acceptable loss

All traders lose. How much you lose is based on your risk, and your risk may not be the same for every trade. This R:R Calculator is focused around how much you are willing to lose per trade. What is your acceptable loss when the trade goes against your plan?

Quickly Identify Trade Details

The idea behind this risk:reward calculator is to help you quickly identify three things.

It does all this just buy entering the price of your planned entry.

R:R Settings

$ Risk

This is the dollar amount you are willing to risk losing per trade. This is used to calculate how many shares to buy based on your entry and risk level. The default $ risk is $100.

Distance to risk = Entry * (% Risk)
# Shares = ($ Risk) / (distance to risk)


This is the default reward you would like to use to start the calculation. It is the ratio used to compute the reward stock price level based on your entry and % risk. A R:R of 1:3 (read one-for-three) means you are risking a $1 loss for a possible $3 gain. The default is "3", 1:3

Distance to risk = Entry * (% Risk)
Reward (long) = Entry + (distance to risk) * default_reward
Reward (short) = Entry - (distance to risk) * default_reward

% Risk

This is the default percent risk you would like to use to start the calculation. It is the percentage risk, from your entry, used to compute the stock price risk level.

Distance to risk = Entry * (% Risk)
Risk (long) = Entry - (distance to risk)
Risk (short) = Entry + (distance to risk)

A percent risk too low (tight risk) may cause you to be "chopped out". Whereas, too high, and you are just throwing away money.

Please Note

The above calculations are just starting points for you to do your own analysis. Don't just set your risk based on a fixed or percent distance from your entry. I usually tie my risk to a key level on the chart, but I use the R:R Calculator as a tool to quickly identify starting points for where I should be looking based on my own trading plan.
