The risk-free rate is also a required input in financial calculations, such as the Black–Scholes formula for pricing stock options and the Sharpe ratio. Note that some finance and economic theories assume that market participants can borrow at the risk-free rate; in practice, very few (if any) borrowers have access to finance at the risk free ...
The risk-free return is constant. Then the Sharpe ratio using the old definition is = = Example 2. An investor has a portfolio with an expected return of 12% and a standard deviation of 10%. The rate of interest is 5%, and is risk-free.
The "risk-free" rate on US dollar investments is the rate on U.S. Treasury bills, because this is the highest rate available without risking capital.

Cost of equity = Risk free rate of return + Beta × (market rate of return – risk free rate of return) where Beta = sensitivity to movements in the relevant market. Thus in symbols we have = + where: E s is the expected return for a security; R f is the expected risk-free return in that market (government bond yield);
The lowest of all is the risk-free rate of return. The risk-free rate has zero risk (most modern major governments will inflate and monetise their debts rather than default upon them), but the return is positive because there is still both the time-preference and inflation premium components of minimum expected rates of return that must be met ...
r f is the risk free rate (i.e. the interest rate on treasury bills) r mt is the return to the market portfolio in period t is the stock's alpha, or abnormal return is the stock's beta, or responsiveness to the market return
where r is the risk-free rate, (μ, σ) are the expected return and volatility of the stock market and dB t is the increment of the Wiener process, i.e. the stochastic term of the SDE. The utility function is of the constant relative risk aversion (CRRA) form: =.
