How does this calculator work?
Credit spread = corporate bond yield − risk-free yield, in basis points (multiply by 100). It represents the extra return investors earn for bearing default risk. A 150 bps spread on a $1,000 bond earns roughly $15 extra per year — use this calculator to see the full income impact over any term.
Formula
How this is calculated
A credit spread measures the extra yield investors demand for lending to a corporation instead of a government. Because governments of developed nations can print money or levy taxes to repay debts, their bonds are treated as essentially risk-free; every additional basis point above that benchmark compensates the bond-holder for credit risk — the possibility the corporate issuer defaults or restructures.
The spread is expressed in basis points (bps) where 1 bps = 0.01 percentage point. A spread of 150 bps means the corporate bond yields 1.50% more than the equivalent-maturity Treasury. Wider spreads signal higher perceived risk — lower credit quality or stressed market conditions. Tighter spreads signal investor confidence and favourable credit conditions. Investment-grade bonds (BBB− and above) typically trade at spreads of 50–300 bps; high-yield ("junk") bonds often exceed 400–600 bps, especially in downturns.
This calculator also estimates the extra annual income per face value and the cumulative extra income over the bond's remaining term, giving a concrete dollar figure to weigh against the additional default risk. It assumes a flat yield curve and does not adjust for differences in liquidity, callability, or tax treatment between corporate and government bonds.
Frequently asked questions
One basis point (bps) equals 0.01 percentage point. A spread of 100 bps means the corporate bond yields exactly 1.00% more than the benchmark. Bond markets use basis points because yield differences are often small but economically meaningful — a 10 bps move on a $1,000 face value bond is worth $1 per year.
A widening spread means investors are demanding more compensation for credit risk — usually because the issuer's financial health has deteriorated, the broader economy is weakening, or market liquidity has fallen. Tightening spreads signal improving conditions or stronger investor confidence.
For USD bonds, the benchmark is typically the US Treasury of matching maturity. For EUR bonds, German Bunds are commonly used. The key is to compare bonds of the same currency and similar maturity, so only credit risk — not currency or duration risk — drives the spread.
