Reward to Risk Ratio Example

How to calculate reward to risk ratio?

  1. First, determine the potential or expected return.

    This can either be the maximum expected monetary gain, or the most likely expected return.

  2. Next, determine the potential maximum loss.

    For example, if you had a 50$ investment, the maximum loss is likely 50$.

  3. Finally, calculate the reward to risk ratio.

    Calculate the RRR using the equation above.
