To calculate the dirty price, you need to know the clean price along with the amount of interest that accrued. The dirty price is calculated by adding the clean price of the bond to the accrued interest.
However, the bond seller may price a bond to include any accrued interest up to the sell date – it is known as the dirty price. The interest a bond will pay out builds every day until the payment date. You can figure the amount of accrued interest on a bond by multiplying the number of days since the last payment by the daily interest rate and the bond face value.
The clean price is the bond’s market price without accrued interest. The interest increases at a steady rate on a bond and calculation of the earned amount happen each day. As a result, the dirty price will change daily until the payout, or coupon payment, date. Once the payout is complete, and the accrued interest resets to zero, the dirty and clean prices are the same. Accrued interest is earned when a coupon bond is currently in between coupon payment dates.
Making informed investment decisions requires an understanding of yield to maturity and dirty price. Investors should compare investment options based on both yield to maturity and dirty price, as well as other factors such as credit rating, maturity date, and liquidity. By doing so, investors can make informed decisions that maximize their returns while minimizing their risk. Yield to maturity is the total return an investor can expect to receive on a bond if they hold it until maturity. It takes into account the coupon rate, the bond price, and the time to maturity.

- Calculating the dirty price of a bond is an essential step in determining the yield to maturity of a bond.
- This means no interest is accumulated because the interest payment was just made.
- Once a coupon payment has been made, there will be no further payments until the next payment date.
For example, if two bonds have the same maturity, but one has a 5% coupon rate, and the other has a 3% coupon rate, the first bond will have a higher yield to maturity. As a result, the seller will pocket the interest, which would be a dirty price, and the buyer will miss out on one coupon payment. A clean price, in contrast, does not include any accumulated interest. Let’s start with calculating the clean price of the bond using the formula. However, r is replaced with 3% instead of 6% as coupons are paid semiannually. Likewise, n is replaced with 20 instead of 10, and C (the periodic coupon payment) is replaced with 26.5 instead of 53 for the same reason.
Introduction to Yield to Maturity and Dirty Price
Bonds that have equal periodic coupon payments are known as level coupon bonds. When discussing bonds, the amount of interest accumulated since dirty price the last coupon payment is called accrued interest. Therefore, a dirty-priced bond includes this interest in calculating bond prices.
What is Dirty Price?
As the next coupon payment date approaches, the accrued interest increases each day until the payment of the coupon. On the day of the coupon payment, the clean price and dirty price are equal since there is no accrued interest until the next market day. When we buy a bond, we are essentially lending money to the issuer for a fixed period of time. However, the interest is paid periodically, and if we buy the bond in the middle of an interest period, we are entitled to a portion of the interest payment. This is called accrued interest, and it is added to the bond price to arrive at the dirty price. Ignoring accrued interest means we are not getting the full return on our investment, and we are essentially leaving money on the table.
Overview on bonds
To calculate yield to maturity, investors can use a financial calculator or an Excel spreadsheet. Yield to Maturity (YTM) is an important concept in fixed income investments, specifically bonds. It is the total return anticipated on a bond if the bond is held until it matures. The YTM takes into account the bond’s current market price, par value, coupon interest rate, and time to maturity. It is an essential metric for investors to evaluate their potential returns from a bond investment.

If you were to graph the bond’s dirty price minus clean price each day, you’d see it rise during the accrual period from zero to the period’s coupon amount. For example, a $1,000 bond might have an annual coupon rate of 6 percent, for a coupon amount of $60. Bonds, as well as a variety of other fixed income securities, provide for coupon payments to be made to bond holders on a fixed schedule. The dirty price of a bond will decrease on the days coupons are paid, resulting in a saw-tooth pattern for the bond value. This is because there will be one fewer future cash flow (i.e., the coupon payment just received) at that point.
The choice between Clean Price and Dirty Price depends on the specific needs of the investor. If an investor plans to hold a bond until maturity, Dirty Price is more relevant because it reflects the actual price paid for the bond, including the accrued interest. However, if an investor plans to sell the bond before maturity, Clean Price is more relevant because it reflects the current market price of the bond without the accrued interest. Investors who purchase fixed-income instruments, such as bonds, anticipate receiving coupon payments on a predetermined timetable.
Therefore, investors should factor in both prices when making investment decisions, ensuring a holistic understanding of their potential investment. Remember, while the clean price is useful for comparing bonds, the dirty price is what you actually pay when purchasing a bond. However, both methods provide the necessary information for investors to make informed decisions. The key is understanding which price—dirty or clean—is being quoted and adjust your calculations accordingly. The clean price of a bond is the quoted price of the bond without considering any accrued interest. It is basically the price that excludes any interest that has accumulated since the last payment period.
The time to maturity of a bond is the number of years till the par value of the bond is paid back. For example, when a corporate bond is initially issued, its maturity is usually 30 years. As time passes after the bond has been issued, fewer years remain until it matures.
