About This Template
Decompose your portfolio's Value at Risk into component contributions with this Risk Budgeting Calculator Excel template. Essential for portfolio managers, risk analysts, and finance students who need to understand how each asset contributes to total portfolio risk using the Euler decomposition method.
What You Can Calculate
This template calculates comprehensive risk metrics for a 3-asset portfolio:
- Portfolio VaR - Total Value at Risk at 95% or 99% confidence
- Component VaR - Each asset's contribution to portfolio risk (sum equals total VaR)
- Risk Betas - Marginal contribution of each asset to portfolio variance
- Diversification Benefit - Risk reduction from combining correlated assets
- Budget Utilization - Track actual risk vs. allocated risk budgets
Required Inputs
Enter the following for your 3-asset portfolio:
- Portfolio Value - Total market value in dollars
- Asset Weights - Allocation percentages (must sum to 100%)
- Annual Volatilities - Standard deviation of returns for each asset
- Correlations - Pairwise correlation coefficients between assets
- Risk Budgets - Allocated risk limits for each asset class
Methodology
The template uses the Euler decomposition (beta approach) for VaR attribution:
- Component VaR = Weight × Beta × Portfolio VaR
- Beta = (Cov × w)_i / Portfolio Variance
This method guarantees that component VaRs sum exactly to total portfolio VaR - a mathematically rigorous decomposition based on Euler's theorem for homogeneous functions.
Assumptions & Limitations
- Returns are assumed to follow a normal distribution
- Volatilities and correlations are constant over the measurement period
- Single-period analysis with annual VaR horizon
- Weights must sum to exactly 100% (no automatic normalization)
Frequently Asked Questions
To add assets, unprotect the Calculator sheet and add rows for additional weights, volatilities, budgets, and correlations. You'll need to expand the portfolio variance formula to include all pairwise covariance terms, then update the (Cov x w) products and beta calculations. For portfolios with many assets, consider using matrix functions like MMULT.
Yes. Enter daily volatilities (annual vol / sqrt(252)) and daily risk budgets. The z-scores remain the same for the chosen confidence level. Alternatively, you can divide the annual Portfolio VaR output by sqrt(252) to approximate daily VaR under the square-root-of-time rule.
The intermediate section reveals the methodology: portfolio variance (sigma2_p) combines all asset variances and covariances; Cov-Weight products show how each asset's risk interacts with the portfolio; Risk Betas measure each asset's marginal contribution to portfolio variance. These help you understand why certain assets contribute more risk than their weight alone would suggest.
