About This Template
The Breakeven Spread Calculator Excel Template provides a ready-to-use financial model for analyzing credit spread risk. Whether you're a credit analyst evaluating corporate bond positions, a portfolio manager assessing spread cushion, or a fixed income student learning duration-based metrics, this spreadsheet delivers professional-grade calculations with full formula transparency.
What You Can Calculate
This template computes 5 key outputs:
- Spread Income — Total spread income earned over the holding period (Spread x HP)
- Breakeven Spread (Duration-Only) — Maximum spread widening before underperforming a Treasury
- Breakeven Spread (Convexity-Adjusted) — More accurate estimate accounting for second-order effects
- Breakeven as % of Spread — Cushion expressed as a percentage of current spread
- Spread Cushion Rating — Strong (>50%), Moderate (25-50%), or Thin (<25%)
Required Inputs
To use this calculator, you'll need:
- Yield Spread — Current spread over benchmark Treasury in basis points (OAS or G-spread)
- Modified Duration — Price sensitivity to yield changes (available from Bloomberg or bond pricing services)
- Holding Period — Your investment horizon in years
- Convexity — Second-order price sensitivity (optional, set to 0 for simple analysis)
Methodology
The simple breakeven formula is (Spread x Holding Period) / Duration. The convexity-adjusted version solves the quadratic: 0.5 x C x ds² - D x ds + S x HP = 0. This tells you how much the spread can widen before your excess return over Treasury turns negative. A higher breakeven percentage means a larger cushion against spread widening.
Assumptions
- Spread changes are instantaneous parallel shifts
- Treasury yield is unchanged (isolating spread risk only)
- No coupon reinvestment risk modeled
- Duration and convexity are constant over the holding period
- Does not account for roll-down return or carry
- For educational purposes only — not financial advice
Frequently Asked Questions
Copy the Calculator sheet to create additional tabs for each bond. Rename each tab (e.g., Bond A, Bond B) and enter the spread, duration, and convexity for each position. This lets you compare breakeven cushions across your portfolio in a single workbook.
Yes. The formulas are fully visible and editable. To add custom spread widening scenarios, copy the output row structure and modify the formula to reference your desired widening amount. Right-click the sheet tab and select Unprotect Sheet to edit any cell.
You need four values: current yield spread over Treasury (in basis points), modified duration, your intended holding period, and optionally convexity. Bloomberg terminals show these as OAS or G-spread, Mod Dur, and Convexity. Most bond pricing services provide these metrics.
