Understanding Interest Expense: A Deep Dive
An interest expense is the cost incurred by an entity for borrowed funds. It’s a non-operating expense shown on the income statement, indicating interest payable on any borrowings—be it bonds, loans, convertible debt, or lines of credit. The expense is essentially calculated by multiplying the interest rate with the outstanding principal amount of the debt. Note that interest expense in the financial statements encompasses interest accrued during the reporting period and not necessarily the amount paid over that period. While it’s tax-deductible for companies, individuals need to consider their jurisdiction and loan purposes to determine tax-deductibility.
For many individuals, mortgage interest stands as the largest category of interest expense throughout their lives, which could amount to tens of thousands of dollars over the term of a mortgage.
Mechanics of Interest Expenses
Interest expense often surfaces as a line item on a company’s balance sheet due to differences between interest accrued and paid. If interest has accrued but remains unpaid, it lands in the ‘current liabilities’ section of the balance sheet. Conversely, prepaid interest appears in the ‘current assets’ section as a prepaid item.
Geographical regions and the purpose of a loan play crucial roles in determining the tax-deductibility of interest expense. For instance, mortgage interest is tax-deductible in the U.S. but not in Canada. Loans meant for genuine investment purposes often allow for tax-deductibility of the interest. However, restrictions apply. In Canada, loans for investments held in registered accounts like RRSP or RESP are non-deductible.
The amount a company incurs as interest expense heavily depends on the broad interest rates in the economy. During periods of high inflation or elevated interest rates, companies with significant debt will face higher interest expenses. Conversely, these expenses decline during lower inflation periods. Subsequently, the level of interest expense directly impacts profitability, especially for companies heavily laden with debt. Investors and analysts closely watch solvency ratios like debt to equity and interest coverage during economic downturns for heavily indebted firms.

Interest Expense Facts: Incurred while servicing debt, often receive favorable tax treatment.

Impact on Profitability: As interest expense grows, it increasingly affects profitability. Analysts use coverage ratios to evaluate deeper implications.
Delving into Interest Coverage Ratio
The interest coverage ratio is calculated by dividing a company’s operating income (EBIT—Earnings Before Interest and Taxes) by its interest expense. This ratio gauging a company’s ability to cover interest expenses with its operating income. A stronger ratio signals better capacity to meet interest obligations.
For instance, a company with $100 million in debt at an 8% interest rate faces $8 million in annual interest charges. If the firm’s annual EBIT is $80 million, the interest coverage ratio would stand at 10, comfortably covering the interest payments. Yet, falling EBIT below $24 million results in an interest coverage ratio dropping below 3, marking potential solvency issues as a ratio under 3 often raises ‘red flags.’
