100% easy way to learn Interest Expense and its impacts.

What is Interest Expense?

Interest expense refers to the cost of borrowing funds or obtaining financial assistance from external sources, such as loans, bonds, or lines of credit. It represents the interest payments made by a business or individual to lenders or creditors for using their money.

Example: ABC Manufacturing Company and its need of Bank Loan.

ABC Manufacturing Company is a small business that specializes in producing custom-made furniture. To expand its operations and meet growing demand, ABC decides to invest in new machinery and technology. However, they lack sufficient funds to make the purchase outright.

To finance the machinery purchase, ABC decides to take out a term loan from a bank. The bank agrees to lend ABC $50,000 at an annual interest rate of 6% for a term of five years. The loan will be repaid in monthly installments.

Calculate Interest Expense (IE)

For the first year, the interest expense can be calculated as follows:

1. Principal Amount (P): $50,000 (the initial loan amount)
2. Interest Rate (R): 6% per annum
3. Time Period (T): 1 year (the first year of the loan term)

Interest Expense (IE) for Year 1:

IE = Principal Amount (P) x Interest Rate (R) x Time Period (T)
IE = $50,000 x 0.06 x 1
IE = $3,000

So, the IE for the first year is $3,000.

ABC Manufacturing Company will pay $3,000 in interest to the bank during the first year as part of its loan repayment. This IE represents the cost of borrowing the funds necessary to purchase the new machinery and technology. It is an essential financial consideration for ABC, as it directly affects the company’s profitability and cash flow management.

As the loan term progresses, the IE will vary each year based on the outstanding loan balance and the applicable interest rate. ABC must accurately account for this interest expense in its financial statements to have a clear understanding of its financial obligations and manage its cash flow effectively.

How to Calculate Interest Expense?

Calculate IE involves determining the cost of borrowing funds or obtaining financial assistance from external sources, such as loans, bonds, or lines of credit. This financial metric is crucial for businesses and individuals as it reflects the interest payments made over a specific period to lenders or creditors for using their money.

Some of these values are shown in Balance sheet or income statement or cash flow statement or other financial statements etc depending on the business model. Few adjustments are made to accounts by journal entry and passing needed values. Finding principal balance, outstanding principal amount, tax rate, non-operating expense etc are important for the business to arrive at the cost of the money.

Here’s a more detailed explanation of how to calculate IE:

1. Identify the Borrowed Amount (Principal): The first step in calculating interest is to identify the amount borrowed, also known as the principal. For example, if a company borrows $100,000 from a bank, the principal amount is $100,000.

2. Determine the Interest Rate: Next, you need to know the interest rate charged on the borrowed funds. The interest rate is expressed as a percentage of the principal amount and is typically specified in the loan agreement. For instance, if the bank charges an annual interest rate of 5%, the interest rate is 0.05 (5% divided by 100).

3. Define the Time Period: You must also determine the time period for which the funds are borrowed. The time period is usually expressed in years, but it can be adjusted for shorter or longer durations, depending on the loan terms. For example, if the loan is for six months, the time period is 0.5 years.

4. Apply the Interest Expense Formula: The interest can be calculated using the following formula:

IE = Principal Amount (P) x Interest Rate (R) x Time Period (T)

5. Calculate the Interest Expense: To calculate the interest, simply plug in the values of the principal amount, interest rate, and time period into the formula and perform the calculation. The result will give you the total interest expense for the specific time period.

Example: Let’s use an example to illustrate the calculation of IE:

Example: XYZ Company XYZ Company borrows $50,000 from a financial institution at an annual interest rate of 8% for a term of two years.

Calculation of Interest Expense:

Principal Amount (P) = $50,000
Interest Rate (R) = 8% = 0.08 (8% divided by 100)
Time Period (T) = 2 years

Interest = $50,000 x 0.08 x 2
Interest = $8,000

In this example, XYZ Company’s interest for the two-year term is $8,000. This means that over the two-year period, the company will pay $8,000 in interest to the financial institution as part of the loan repayment.

By calculating interest accurately, businesses can manage their borrowing costs effectively, plan for loan repayments, and assess the financial implications of borrowing funds. This information is essential for budgeting, cash flow management, and overall financial decision-making.

What is Interest Expense Coverage Ratio?

The Interest Expense Coverage Ratio measures a company’s ability to cover its interest expenses with its earnings before interest and taxes (EBIT). It is calculated as:

Interest Expense Coverage Ratio = Earnings Before Interest and Taxes (EBIT) / Interest Expense

         This ratio helps assess the company’s financial health and its ability to meet interest obligations.

Example 1: Car Loan Let’s consider a car loan taken by an individual from a bank. The individual borrows $20,000 at an annual interest rate of 5% for a term of five years. The bank charges interest on a monthly basis.

Interest Charged: For the first month, the interest charged can be calculated as follows:

Principal Amount (P) = $20,000
Monthly Interest Rate (R) = (5% / 12) = 0.4167% (5% divided by 12 months)
Time Period (T) = 1 month

Interest Charged for Month 1 = $20,000 x 0.4167% x 1
Interest Charged for Month 1 = $83.33

So, for the first month, the interest charged is $83.33.

IE: Over the entire accounting period, the interest expense will be the sum of interest charged for each month. Let’s calculate the interest expense for the entire year:

IE for Year 1 = Interest Charged for Month 1 + Interest Charged for Month 2 + … + Interest Charged for Month 12
IE for Year 1 = $83.33 + $82.88 + … + $1.85
IE for Year 1 ≈ $1,000 (rounded off for simplicity)

So, the IE for the first year of the car loan is approximately $1,000.

In this example, the interest charged for each month represents the actual amount of interest paid by the individual to the bank for using the borrowed funds during that specific month. On the other hand, the interest expense for the entire year includes the total interest charged over the year, considering the regular monthly payments made by the individual.
