Bond Dirty Price Calculator
Investing in bonds requires understanding different price metrics. One important measure is the Dirty Price of a bond. Unlike the clean price, the dirty price includes accrued interest, representing the actual price a buyer pays.
The Bond Dirty Price Calculator simplifies this calculation by adding the clean price to accrued interest, helping investors make informed decisions and accurately assess their investments.
Formula
The dirty price of a bond is calculated as:
Dirty Price = Clean Price + Accrued Interest
Where:
- Clean Price is the quoted price of the bond excluding interest.
- Accrued Interest is the interest earned on the bond since the last coupon payment, which the buyer compensates the seller for.

Example
