What is the Capital Asset Pricing Model (CAPM)?

The Capital Asset Pricing Model (CAPM) is a widely used financial formula designed to estimate the expected return on an investment, considering its level of risk relative to the overall market.

CAPM helps answer a fundamental investment question:

“Given the market's risk, how much return should I expect for this investment?”

CAPM Formula:

CAPM = 𝑅𝑓 + 𝛽 × (𝑅𝑚 − 𝑅𝑓)
Where:
  • Rf = Risk-free rate (e.g., U.S. Treasury bond yield)
  • β (Beta) = The asset's volatility relative to the market
  • Rm = Expected market return
  • (Rm − Rf) = Market risk premium

How to Use the CAPM Calculator

  1. Enter the Risk-Free Rate – Typically the yield on government securities
  2. Input the Beta (β) – The asset’s volatility relative to the market
  3. Add the Expected Market Return – Estimate based on market forecasts
  4. Click "Calculate" – Instantly get the expected return

CAPM Example: Basic Calculation

Let’s say:
  • Risk-Free Rate (Rf) = 3%
  • Beta (β) = 1.1
  • Market Return (Rm) = 8%
Calculation:

CAPM = 3% + 1.1 ×(8% − 3%)
= 3% + 5.5%
= 8.5%

Expected Return: 8.5%

Understanding CAPM: Key Components Explained

1. Expected Return (ER)

The return you expect to receive from an investment, accounting for its risk. If the actual return is lower than this, the investment may not be worth it.

2. Risk-Free Rate (Rf)

The guaranteed return on a zero-risk investment—usually a government bond like a U.S. Treasury.

3. Beta (β)

A measure of how much an asset moves in response to the market:
  • β = 1 → Moves with the market
  • β > 1 → More volatile than the market
  • β < 1 → Less volatile than the market
Example: A stock with β = 1.5 will likely rise or fall 1.5% for every 1% move in the market.

4. Market Risk Premium (Rm - Rf)

The additional return expected from investing in the market over a risk-free investment.

Example:
If market return = 8% and risk-free rate = 5%,

Market Risk Premium
=Market Risk Premium=8%−5%=3%

Real-Life CAPM Example: Investing in Tesla (TSLA)

Let’s say you’re analyzing Tesla’s potential return:
  • Risk-Free Rate (Rf) = 3%
  • Expected Market Return (Rm) = 10%
  • Tesla’s Beta (β) = 1.8

CAPM Calculation:

Expected Return
= 3% + 1.8 × (10% − 3%)
= 3% + 12.6%
= 15.6%
Expected Return = 15.6%

Interpretation:

According to CAPM, an investor should expect a 15.6% annual return to justify the risk of investing in Tesla. If you expect a higher return, it may be undervalued. If not, it could be overpriced.
