Calculate credit spread in basis points, implied default probability, DV01, and price sensitivity. Compare against rating benchmarks.
Credit spread is the yield difference between a risky bond and a reference benchmark, usually expressed in basis points. It is one of the standard ways to summarize how much extra return investors are demanding for credit risk and related uncertainty.
This calculator translates that yield gap into basis points, implied default assumptions, and simple price-sensitivity measures. It also compares the result against broad rating-tier ranges so you can see whether the bond is trading more like investment-grade or high-yield credit.
That makes the page useful for fixed-income screening, credit-risk discussions, and quick checks on whether a quoted yield premium is small, typical, or unusually wide.
A spread number alone is easy to quote but harder to interpret. Converting it into basis points, recovery-based default assumptions, and rough price sensitivity makes it easier to compare one bond with another or to explain why a spread move matters.
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 not a pure default forecast. It can also reflect liquidity, market stress, maturity effects, and the structure of the bond itself. Even so, spreads remain one of the fastest ways to compare how the market is pricing credit risk across issuers and sectors.
The implied default probability shown by simple spread models depends heavily on the recovery assumption. A lower recovery rate means investors can tolerate a lower default probability for the same spread, while a higher recovery assumption implies that more defaults can be absorbed before the spread looks insufficient. The result is useful as a rough interpretation aid, not as a literal forecast.
Spread comparisons work best when the bonds are similar in maturity, seniority, and optionality. A long-dated subordinate bond will normally trade wider than a short-dated senior unsecured one even from the same issuer. The benchmark table is most useful as a starting point for context, not as a final valuation model.

This page subtracts the benchmark yield from the bond yield to express the spread in percentage points and basis points, then applies a simple loss-given-default heuristic to convert that spread into an implied annual default assumption. It also projects a cumulative default probability across the selected maturity as a rough interpretation aid.
The implied default output is intentionally simplified. Actual market spreads also reflect liquidity, optionality, maturity structure, tax differences, and changing recovery expectations, so the probability estimate should be treated as a rough credit-risk translation rather than a literal forecast.
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.
