About This Template
Calculate your bond portfolio's interest rate sensitivity with this Portfolio Duration Calculator Excel template. Essential for fixed-income portfolio managers, institutional investors, and finance students studying duration-based risk management strategies.
What You Can Calculate
This template computes three key portfolio metrics:
- Portfolio Modified Duration — The weighted average duration of your bond holdings, measuring how much your portfolio value will change for a 1% move in interest rates
- Portfolio DV01 — Dollar Value of 01, showing the dollar change in portfolio value for a 1 basis point (0.01%) yield shift
- Total Market Value — Aggregate value of all bond positions in your portfolio
Required Inputs
For each bond position (up to 10), enter:
- Market Value — Current market value of the position (not face value)
- Modified Duration — The bond's modified duration in years (typically 0-30 for vanilla bonds)
Leave unused bond rows as zero — they are automatically excluded from calculations.
Methodology
Portfolio duration is calculated as the market-value-weighted average of individual bond durations:
D_portfolio = SUM(MV_i x D_i) / SUM(MV_i)
DV01 converts this to dollar terms: DV01 = Portfolio Duration x Total MV / 10,000
Assumptions & Limitations
- Weights based on market value (not face value)
- Modified duration assumes option-free bonds
- Parallel yield curve shifts assumed
- First-order approximation only (convexity not included)
