Enter the investment return and the risk-free rate into the calculator to determine the excess return. This calculator helps to evaluate the performance of an investment relative to a risk-free asset.

Excess Return Formula

The following formula is used to calculate the excess return:

ER = IR - RFR

Variables:

  • ER is the excess return (%)
  • IR is the investment return (%)
  • RFR is the risk-free rate (%)

To calculate the excess return, subtract the risk-free rate from the investment return.

What is Excess Return?

Excess return is the difference between the return of an investment and the return of a risk-free benchmark, such as a government treasury bond. It represents the additional gain (or loss) that an investor receives (or incurs) from taking on the additional risk compared to a risk-free investment. Excess return is a common measure used in finance to assess the performance of investment portfolios and individual securities.

How to Calculate Excess Return?

The following steps outline how to calculate the Excess Return.


  1. First, determine the investment return (IR) as a percentage.
  2. Next, determine the risk-free rate (RFR) as a percentage.
  3. Use the formula from above = ER = IR – RFR.
  4. Finally, calculate the Excess Return (ER) as a percentage.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Investment return (IR) = 8%

Risk-free rate (RFR) = 2%
