CAPM Calculator (Capital Asset Pricing Model)
Calculate expected investment returns, cost of equity (Ke), and equity risk premiums using the Capital Asset Pricing Model (CAPM).
What is the CAPM Calculator (Capital Asset Pricing Model)?
The ToolboxDock CAPM Calculator (Capital Asset Pricing Model) is a free, 100% browser-based financial utility that calculates money metrics directly in client-side RAM with zero server transfers. It provides instant mathematical modeling for loans, investments, taxes, and amortization schedules while ensuring complete confidentiality of your sensitive financial data.
The Capital Asset Pricing Model (CAPM) establishes the foundational relationship between systematic risk (Beta) and expected financial return, serving as the industry standard for determining corporate cost of equity and investment discount hurdle rates.

How to Use the CAPM Calculator (Capital Asset Pricing Model)
Follow these 3 simple steps for instant, accurate calculations.
1. Enter Risk-Free Rate (Rf)
Input the benchmark yield on risk-free government bonds (e.g. 10-year US Treasury yield, such as 4.25%).
2. Specify Beta (β) & Market Return (Rm)
Enter the asset's systematic risk sensitivity (Beta) and expected market benchmark return (e.g. S&P 500 average 10.0%).
3. Analyze Expected Return & Risk Premium
Review the required rate of return on equity, market equity risk premium (ERP), and asset risk premium.

Capital Asset Pricing Model (CAPM) Formula
Calculates the expected required return on equity by adding the risk-free rate to the asset's beta multiplied by the market equity risk premium.
Core CAPM Calculator (Capital Asset Pricing Model) Inputs & Terminology
The minimum rate of return an investor requires to hold an asset given its systematic market risk.
The theoretical rate of return of an investment with zero default risk, typically represented by long-term government sovereign bonds.
A statistical measure of an asset's covariance and volatility relative to the overall market portfolio (Beta = 1.0 matches market volatility).
The excess return earned above the risk-free rate for bearing broad equity market risk (Rm - Rf).
