> The credit spread calculator works out the difference between a corporate bond's yield and a government bond of the same maturity – the extra return investors demand for credit risk – in percent and basis points.

## Inputs

- Corporate bond yield (%)
- Government bond yield (%)

## Results

- Credit spread
- Credit spread in basis points

## Formula

```
Credit spread = corporate bond yield − government bond yield
In basis points = spread × 100
```

## Explanation

Credit spreads widen when investors worry about defaults (for example in recessions) and narrow when confidence is high. Investment-grade spreads are often around 1–2 percentage points; high-yield spreads 3–6 or more.

### How to use the Credit Spread Calculator

- **Corporate bond yield**
- **Government bond yield**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the corporate bond yield and the government bond yield of the same maturity.

### Tips

- Check whether rates are quoted annually, semi-annually or per period.
- Bond prices and yields move in opposite directions – a higher yield means a lower price.
- Use the bond's clean price (without accrued interest) for yield calculations.
- Credit ratios are most useful when tracked over several years.

### Common mistakes to avoid

- Confusing the coupon rate with the yield.
- Using the face value instead of the market price.
- Forgetting that callable bonds may be redeemed before maturity.
