CAPM calculator ?

Enter the risk-free rate, the asset's beta, and the expected market return. The calculator works out the expected return under CAPM.

Usually the yield on government bonds — an asset considered essentially risk-free
A measure of volatility relative to the market: 1 means the asset moves with the market, above 1 means more than the market, below 1 means less

How it is calculated

Expected return = risk-free rate + beta × (market return − risk-free rate). The second part of the formula is the market risk premium multiplied by beta: the more an asset swings relative to the market, the more premium an investor demands for taking on that extra risk.

A beta above 1 means the asset moves more than the market on average (rises faster in an upswing, falls faster in a downturn) — such assets require a higher expected return to compensate for the added risk. A beta below 1 means the asset is more stable than the market as a whole.

The CAPM result is often used as the cost of equity estimate in a WACC calculation — that's exactly what's meant when the WACC calculator notes that required return on equity is often estimated via CAPM.

CAPM is a simplified model with known limitations: it assumes all risk boils down to a single factor (the market) and ignores things like an asset's liquidity or company-specific risks. It's a standard starting estimate, not a guaranteed forecast of actual returns.
