About This Template
Calculate weighted average life (WAL) for project finance debt with this professional Excel template. Whether you're structuring a construction loan, analyzing refinancing options, or preparing lender presentations, this template gives you instant WAL calculations with full formula transparency.
What You Can Calculate
Enter your construction draws and principal repayments to instantly calculate:
- Weighted Average Life - The average time each dollar of principal is outstanding, using the industry-standard weighted outstanding method
- Peak Debt Outstanding - Maximum loan balance during the project lifecycle (typically at end of construction)
- Ending Balance - Remaining principal at maturity, highlighting any balloon payment
- Sum of Outstanding - Total period-end balances used in the WAL numerator
Required Inputs
Simply enter your loan schedule in the light blue cells:
- Construction Draws - Up to 5 periods of loan drawdowns during construction (in $ millions)
- Principal Repayments - Up to 15 periods of scheduled principal payments after construction
Leave unused periods as 0. The template automatically calculates the running outstanding balance in column D.
Methodology
This template uses the weighted outstanding method per Yescombe's "Principles of Project Finance" (Chapter 12):
WAL = Sum(Outstanding Balances) / Peak Outstanding
Each period where the loan balance is positive contributes to the WAL calculation. This method is standard in project finance and gives lenders a clear measure of their credit exposure duration.
Assumptions & Limitations
- Annual periods (scale inputs for semi-annual or quarterly schedules)
- Draws and repayments occur at end of each period
- Enter 0 for unused periods; only rows with values > 0 are included
- No revolving credit or re-borrowing during repayment phase
Frequently Asked Questions
Loan term is total time from first draw to final payment. WAL measures average time each dollar of principal is outstanding. A bullet loan has WAL near its term; an amortizing loan has WAL roughly half its term.
WAL measures credit exposure duration. Shorter WAL means faster principal recovery and lower risk. Lenders often set maximum WAL policies (7-10 years) and price loans partly based on WAL.
