ABC must then reduce the $100,000 premium on its bonds payable during each accounting period that the bonds are outstanding, until the balance in the Premium on Bonds Payable account is zero when the company has to pay back the investors. The bonds have a term of five years, so that is the period over which ABC must amortize the premium. Notice that under both methods of amortization, the book value at the time the bonds were issued ($104,100) moves toward the bond’s maturity value of $100,000. The reason is that the bond premium of $4,100 is being amortized to interest expense over the life of the bond.

One big caveat about the straight-line method As simple as the straight-line method is, the main problem with it is that the IRS generally doesn’t allow you to use it anymore. As IRS Publication 550 states, for bonds issued after Sept. 27, 1985, taxpayers must amortize bond premium using the constant-yield method, which differs from the straight-line method. For older bonds issued before Sept. 27, 1985, the straight-line method is still an option.

When an investor buys a bond at a price higher than its face value, they are effectively paying a premium for that bond. This premium often arises because the bond’s coupon rate (interest rate) is higher than the current market rate, making it more attractive to investors. Reducing the balance in the account Premium on Bonds Payable by the same amount each period is known as the straight-line method of amortization. A more precise method, the effective interest rate method of amortization, is preferred when the amount of the premium is a large amount. The amount of the premium is recorded in a separate bond-related liability account. Over the life of the bonds the premium amount will be systematically moved to the income statement as a reduction of Bond Interest Expense.

  1. In order to calculate the premium amortization, you must determine the yield to maturity (YTM) of a bond.
  2. Amortizable bond premiums refer to the portion of the premium paid by an investor for purchasing a bond that is deductible over the life of the bond.
  3. 11 Financial may only transact business in those states in which it is registered, or qualifies for an exemption or exclusion from registration requirements.
  4. Companies do not always issue bonds on the date they start to bear interest.

In the context of wealth management and bond investing, understanding and managing amortizable bond premiums is essential, as they can impact the bond’s yield, tax implications, and overall investment strategy. Investors can incorporate amortizable bond premium management into their wealth management strategies by diversifying their bond portfolios, considering the tax implications of their investments, and managing interest rate risk. This can help optimize bond portfolios, minimize tax liabilities, and achieve better overall returns. When a bond has an interest rate that’s higher than prevailing rates in the bond market, it will typically trade at a price higher than its face value. Such a bond is said to trade at a premium, and the tax laws allow you to amortize the bond’s premium between the time you purchase it and its maturity date in order to offset your income. Below, you’ll learn more about bond premium amortization and one method of calculating it known as the straight-line method.

To calculate the amortizable bond premium using the constant yield method, multiply the bond’s adjusted cost basis by its effective interest rate and subtract the annual interest payment. A diversified bond portfolio is essential to managing risk and maximizing returns. Including bonds with varying coupon rates, maturities, and credit ratings can help investors achieve a balanced portfolio that takes advantage of amortizable bond premiums while managing interest rate risk.

What are the tax implications of an amortizable bond premium?

For a bond investor, the premium paid for a bond represents part of the cost basis of the bond, which is important for tax purposes. If the bond pays taxable interest, the bondholder can choose to amortize the premium—that is, use a part of the premium to reduce the amount of interest income included for taxes. The preferred method for amortizing the bond premium is the effective interest rate method or the effective interest method. Under the effective interest rate method the amount of interest expense in a given year will correlate with the amount of the bond’s book value. This means that when a bond’s book value decreases, the amount of interest expense will decrease.

How to use the straight-line method Calculating bond premium amortization using the straight-line method couldn’t be simpler. First, calculate the bond premium by subtracting the face value of the bond from what you paid for it. Then, figure out how many months are left before the bond matures and divide the bond premium by the number of months remaining. Below is a comparison of the amount of interest expense reported under the effective interest rate method and the straight-line method. Note that under the effective interest rate method the interest expense for each year is decreasing as the book value of the bond decreases. Under the straight-line method the interest expense remains at a constant annual amount even though the book value of the bond is decreasing.


The updated bond cost basis is calculated by subtracting the annual bond premium amortization from the initial cost basis. This updated cost basis is then used to calculate the amortization for the following year. The yield to maturity is the total return an investor can expect if they hold the bond until it matures.

A bond premium occurs when the price of the bond has increased in the secondary market due to a drop in market interest rates. A bond sold at a premium to par has a market price that is above the face value amount.

In order to calculate the premium amortization, you must determine the yield to maturity (YTM) of a bond. The yield to maturity is the discount rate that equates the present value of all coupons and principal payments to be made on the bond to its initial purchase price. When market interest rates decrease, for any given bond, the fixed coupon rate is higher relative to other bonds in the market. It makes the bond more attractive, and it is why the bond is priced at a premium. For the remaining eight periods (there are 10 accrual or payment periods for a semi-annual bond with a maturity of five years), use the same structure presented above to calculate the amortizable bond premium.

The constant yield method provides a more accurate reflection of the bond’s yield, while the straight-line method is simpler and easier to understand. Investors should consider their specific investment objectives and tax situation when choosing the appropriate method. Amortizable bond premiums refer to the portion of the premium paid by an investor for purchasing a bond that is deductible over the life of the bond. The format of the journal entry for amortization of the bond premium is the same under either method of amortization – only the amounts change. The constant-yield method will give you a smaller amortization amount than the straight-line method in early years, with the constant-yield amortization figure growing in later years.
