Calculate credit spread in basis points, implied default probability, DV01, and price sensitivity. Compare against rating benchmarks.
Credit spread is the difference between a bond's yield and the risk-free benchmark yield, expressed in basis points (bps). It represents the additional compensation investors demand for taking on credit risk — the risk that the issuer may default on interest or principal payments.
Credit spreads are the cornerstone of fixed-income analysis. They reflect the market's assessment of an issuer's creditworthiness and fluctuate with economic conditions, company fundamentals, and market sentiment. Wider spreads indicate higher perceived risk; tighter spreads indicate lower risk or stronger demand.
This calculator computes credit spreads, translates them into implied default probabilities using recovery rate assumptions, and provides a sensitivity analysis showing how spread changes affect bond prices. The rating benchmark table lets you compare any bond's spread against typical levels for each credit rating tier, from AAA to CCC. Check the example with realistic values before reporting. Use the steps shown to verify rounding and units. Cross-check this output using a known reference case.
Bond investors need credit spread analysis to evaluate whether the extra yield compensates for the default risk. This calculator instantly converts yield differentials into actionable metrics — implied default probability, dollar spread income, and price sensitivity — helping you make informed investment decisions. Keep these notes focused on your operational context.
Credit Spread = Bond Yield − Benchmark Yield. Spread (bps) = Spread × 10,000. Annual PD = Spread / (1 − Recovery Rate). Cumulative PD = 1 − (1 − Annual PD)^n.
Result: Spread: 250 bps — Annual PD: 4.17% — Cumulative PD: 34.5%
A bond yielding 6.5% vs a 4.0% benchmark produces a 250 basis point spread. With a 40% recovery rate, the market-implied annual default probability is 4.17%. Over 10 years, cumulative default probability reaches 34.5%. This spread is consistent with BB-rated credit.

A credit spread is the yield difference between a corporate (or risky) bond and a comparable risk-free government bond. It compensates investors for the additional risk of potential default, downgrade, or illiquidity.
Credit spreads widen during economic downturns, financial crises, or issuer-specific problems. They tighten during economic expansion and strong market demand. Key drivers include GDP growth, default rates, earnings, leverage ratios, and overall market risk appetite.
The implied default probability represents the annual likelihood of default that would make the spread "fair" given the recovery rate assumption. If actual default rates are lower, the bond offers excess return. If higher, you lose money on average.
AAA bonds typically trade at 30–60 bps, AA at 50–100 bps, A at 80–150 bps, and BBB at 130–250 bps. High-yield bonds: BB at 250–400 bps, B at 350–600 bps, and CCC at 600–1200+ bps. These ranges vary with market conditions.
Recovery rate is the percentage of face value investors recover if the issuer defaults. Historical averages: senior secured ~60%, senior unsecured ~40%, subordinated ~25%. Recovery rates vary by industry, economic conditions, and collateral quality.
Use credit spread for bullet bonds without embedded options. Use OAS (option-adjusted spread) for callable, putable, or convertible bonds where the embedded option affects cash flows. OAS removes the option value from the spread, isolating pure credit risk.
