CAPM Calculator – Capital Asset Pricing Model

Sharpe-Lintner Capital Asset Pricing Model (CAPM) Standards

The Capital Asset Pricing Model (CAPM) describes the relationship between systematic risk and expected return for assets, particularly equities:

• Fundamental Equation: $E(R_i) = R_f + \beta_i \times [E(R_m) - R_f] + \alpha$

• Risk-Free Rate ($R_f$): Yield on benchmark government sovereign debt (typically the 10-Year US Treasury yield).

• Beta ($\beta$): Sensitivity of an asset's returns relative to market portfolio swings.

• Market Risk Premium (MRP): The excess return demanded by investors over the risk-free rate for holding risky equities: $[E(R_m) - R_f]$.

• Cost of Equity ($K_e$) in WACC: Serves as the equity discount rate in corporate valuation: $\text{WACC} = \left(\frac{E}{V} \times K_e\right) + \left(\frac{D}{V} \times K_d \times (1 - t)\right)$.

Asset Beta Benchmarks Table

• Defensive Healthcare / Pharma: $E(R_i) = 4.25\% + (0.55 \times 5.75\%) = 7.41\%$

• Regulated Utility: $E(R_i) = 4.25\% + (0.65 \times 5.75\%) = 7.99\%$

• Broad Market Index / S&P 500: $E(R_i) = 4.25\% + (1.00 \times 5.75\%) = 10.00\%$

• Large-Cap Tech / Apple: $E(R_i) = 4.25\% + (1.20 \times 5.75\%) = 11.15\%$

• High-Beta Growth / Tesla: $E(R_i) = 4.25\% + (1.85 \times 5.75\%) = 14.89\%$

How to Use This Calculator

Enter Risk-Free Rate Rf (%), Asset Systematic Beta (β), Expected Market Return E(Rm) (%), Size / Specific Risk Premium (%) into the input fields and the calculator will instantly compute Expected Return E(Ri), Market Risk Premium (MRP). All calculations happen in real time — no submission or page reload required. You can adjust any input value and see the result update immediately.

Understanding Your Result

The CAPM – Capital Asset Pricing Model result gives you a precise, calculated value based on the inputs you provide. Compare your result against published benchmarks from CDC, USDA, and DOE to assess where you stand. A single calculation is a useful starting point, but tracking this metric over time — as inputs change — gives you a much more complete picture.

Practical Application

The CAPM – Capital Asset Pricing Model is most useful when you have specific, real-world data to enter. For example: enter your actual Risk-Free Rate Rf (%) to calculate your expected return e(ri). The result helps general public, households, and individuals make informed decisions about everyday calculations for health, home, nutrition, time, and personal planning. This calculator is trusted by professionals and individuals alike because it follows the exact formulas validated by CDC, USDA, and DOE.

Accuracy Notes and Limitations

Results are general estimates. Your specific conditions (climate, lifestyle, physical state) may require adjustments. The accuracy of any calculator is limited by the quality of the inputs provided. Double-check your units before entering values — unit errors are the most common source of incorrect results. For critical decisions, cross-reference with at least one additional source or professional consultation.

Frequently Used With

This calculator is often used alongside other daily life tools to build a complete analytical picture. Combining multiple related calculations provides stronger evidence for decisions than relying on any single metric.
