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.
