 ## Blog The cash interest payment is still the stated rate times the principal. The interest on carrying value is still the market rate times the carrying value. The difference in the two interest amounts is used to amortize the discount, but now the amortization of discount amount is added to the carrying value. On a period-by-period basis, accountants regard the effective interest method as far more accurate for calculating the impact of an investment on a company’s bottom line. To obtain this increased accuracy, however, the interest rate must be recalculated every month of the accounting period; these extra calculations are a disadvantage of the effective interest rate. If an investor uses the simpler straight-line method to calculate interest, then the amount charged off each month does not vary; it is the same amount each month.

• It’s the number that the lender typically advertises as the interest rate.
• The effective interest rate method is commonly used for bond premiums amortization.
• (Figure)When a bond sells at a discount, the carrying value ________ after each amortization entry.
• The Premium must be amortized or written off by the company in its books of accounts over the bond’s life systematically.
• The bond’s carrying value in Column 6 is thus increased by \$508, from \$92,976 to \$93,484.

The amortization amount is calculated by dividing the value of the amortization premium by its life. Typically companies make an amortization table for the amortization of bond premiums each year. The company also issued \$100,000 of 5% bonds when the market rate was 7%. It received \$91,800 cash and recorded a Discount on Bonds Payable of \$8,200. This amount will need to be amortized over the 5-year life of the bonds. Using the same format for an amortization table, but having received \$91,800, interest payments are being made on \$100,000.

Note that the only static figure is the amount of cash interest — interest expense and amortization are different in every single year. Over time, the carrying amount of the bonds is slowly reduced to \$100,000 due to the amortization of the premium each year. Solve for present value to get \$93,855.43, or the amount investors will pay for these bonds if they want a 10% annual return, also known as a yield to maturity. Here’s how to account for bonds under the straight line and effective interest methods. As stated above, the EIR is built on forecasted cash flows, assuming that the cash flows and the expected lifespan of a financial instrument (or a group of similar financial instruments) can be reliably estimated. However, in rare instances where reliable estimation of cash flows or the expected lifespan of a financial instrument is impossible, the entity uses the contractual cash flows over the entire contractual term of the financial instrument. For example, Valenzuela bonds issued at a discount had a carrying value of \$92,976 at the date of their issue. An interest-bearing asset also has a higher effective interest rate as more compounding occurs. For example, an asset that compounds interest yearly has a lower effective rate than an asset that compounds monthly. Volatility profiles based on trailing-three-year calculations of the standard deviation of service investment returns. While the phrasing of the cited paragraphs may not clearly indicate whether this rule also applies to financial liabilities, the IASB confirmed this in the basis for conclusions to IFRS 9 (BC4.252-3). Thus, when a financial liability measured at amortised cost is modified without this modification causing derecognition, a gain or loss should be recognised in P/L.

## Amortizing Bond Discount with the Effective Interest Rate Method

Note that under the effective interest rate method the interest expense for each year is increasing as the book value of the bond increases. Under the straight-line method the interest expense remains at a constant amount even though the book value of the bond is increasing. The accounting profession prefers the effective interest rate method, but allows the straight-line method when the amount of bond discount is not significant. The difference between the required cash interest payment of \$6,000 in Column 3 (\$100,000 x 6%) and the effective interest expense of \$6,508 is the required discount amortization of \$508 in Column 4. Under the effective interest method, a constant interest rate—equal to the market rate at the time of issue—is used to calculate the periodic interest expense.

### How many methods of amortization are there?

For accounting purposes, there are six amortization methods—straight line, declining balance, annuity, bullet, balloon, and negative amortization.

The amount paid is found by multiplying the interest rate on the bond certificate by the face value. (Figure)The cash interest payment a corporation makes to its bondholders is based on ________. (Figure)The effective-interest method of bond amortization finds the difference between the ________ https://www.bookstime.com/ times the ________ and the ________ times the ________. (Figure) illustrates the relationship between rates whenever a premium or discount is created at bond issuance. Figure 13.10 illustrates the relationship between rates whenever a premium or discount is created at bond issuance.

## How to Amortize Bond Premium?

The formulas used for amortization calculation can be kind of confusing. So, let’s first start by describing amortization, in simple terms, as the process of reducing the value of an asset or the balance of a loan by a periodic amount . To calculate interest expense for the first period, we multiply the carrying value of the bonds (\$106,710.08) by investors’ required return (8%) to get interest expense of \$8,536.81. First, let’s enter the particular to create the amortization table format for the effective interest method in Excel. In the following example, assume that the borrower acquired a five-year, \$10,000 loan from a bank. She will repay the loan with five equal payments at the end of the year for the next five years. In its simplest form, discount amortization is a process used to allocate the discount on bonds, or other long-term debt, evenly over the life of the instrument. As with the discount example, the total interest expense over its lifetime under the straight-line and the effective interest methods is the same. When you use the effective interest method, the carrying value of the bonds is always equal to the present value of the future cash outflow at each amortization date.

## Formula for Calculating the Effective Interest Rate

Once the bond premium is calculated, you need to decide how the bond premium shall be amortized. Based on your chosen method, you can amortize the bond premium in the books of accounts. One needs to calculate the number of bond premiums to amortize bond premiums. The same can be calculated by reducing the face value of the bond from its issue price. The table below shows how this example bond would be accounted for over the full 10-year period.

Unlike the real interest rate, the effective interest rate does not take inflation into account. If inflation is 1.8%, a Treasury bond (T-bond) with a 2% effective interest rate has a real interest rate of 0.2% or the effective rate minus the inflation rate. Therefore, the effective interest rate https://www.bookstime.com/articles/amortizing-bond-premium-with-the-effective-interest-rate-method for the quoted investment is 10.25%. The compounding periods will generally be monthly, quarterly, annually, or continuously. It’s the number that the lender typically advertises as the interest rate.
