How to Calculate Risk Free Rate of Return

Risk-Free Rate of Return Calculator

The risk-free rate of return is the theoretical rate of return of an investment with zero risk. It represents the minimum return an investor expects for taking on any investment risk. In practice, it's often approximated by the yield on government bonds of a specific maturity.
