Equity Risk Premium Calculator
The Equity Risk Premium (ERP) is a measure used in finance to understand the expected return of the stock market over a risk-free rate. This concept is essential for investors looking to gauge potential returns compared to safer investments like government bonds. By using the ERP, investors can assess if the additional risk of investing in the stock market is justified by the potential reward.
Formula
The formula to calculate the Equity Risk Premium is:
ERP = Rm – Rf
where:
- ERP is the Equity Risk Premium
- Rm is the Market Return
- Rf is the Risk-Free Rate
How to Use
- Enter the expected market return percentage (Rm).
- Input the current risk-free rate (Rf), usually based on government bond yields.
- Click “Calculate” to view the Equity Risk Premium, indicating the premium investors expect over a risk-free investment.
Example
Suppose the market return is 8%, and the risk-free rate is 3%. To calculate the Equity Risk Premium:
ERP = 8% – 3%
ERP = 5%
In this example, the equity risk premium is 5%, indicating the expected return above a risk-free rate.
