CAPM & Beta

Riskier assets should pay more. The Capital Asset Pricing Model puts a number on it — see where any stock lands on the Security Market Line.

Presets

The Capital Asset Pricing Model says an asset's expected return equals the risk-free rate plus beta times the market risk premium. Beta measures how much a stock swings with the market — a beta of 2 is twice as volatile, and demands twice the premium. Educational tool, not financial advice.

Governing equation

Reading this result: Beta above 1 amplifies the market premium: this asset is expected to return 10.20%, above the 9% market, and to swing harder in both directions.

How it works

CAPM prices risk: expected return = risk-free rate + β·(market return − risk-free rate). Beta measures an asset's volatility relative to the market — a beta above 1 is more volatile and commands a higher expected return, plotted along the Security Market Line.

Frequently asked questions

Is this capm calculator beta tool really free?▾
Yes. CAPM & Beta runs entirely in your browser using your device's own compute, so local use is free forever. You only pay Compute Tokens if you scale a job to the cloud.
Do I need to install anything?▾
No. Everything runs client-side in a modern browser — no downloads, no license, no account required to start.
Can I save or share my simulation?▾
Create a free account to save projects, and use a shareable embed or minted DOI to publish a live, interactive version anywhere.
How accurate are the results?▾
The solver uses established numerical methods, but results are for research and educational purposes and should be validated against experiment or professional review before you rely on them.
