interest expense
Interest expense is the cost a business pays for borrowed money, the naira it hands over to lenders for the privilege of using their funds.
In plain English
Why does a company that is clearly making sales still end up with less profit than you expected? Look at its interest expense before you look anywhere else.
Interest expense is simply the cost of borrowing. If a business takes a loan, an overdraft, or issues a bond, the lender wants something back for letting go of their money, and that something is interest. It sits on the income statement as a cost, calmly eating into profit before tax is even calculated.
Say a small manufacturing company in Aba takes a bank loan of ₦20,000,000 to buy new machines, at 18 percent per year. That means roughly ₦3,600,000 every year goes out as interest expense alone, before the company has covered salaries, rent, or raw materials. That machine had better be earning its keep.
In the United Kingdom, a small retailer might use a business loan or a revolving credit facility to manage stock through the year. The interest on that facility shows up the same way, as an expense that chips away at the bottom line regardless of how good sales were that month.
For someone in the diaspora sending money home to keep a family business afloat, this term matters more than it seems. If that business is servicing a loan, part of what looks like income is actually just covering interest, not growing the business at all. It helps to ask what the loan is for and how much interest it is calmly costing every month.
Lenders are not being unkind by charging interest, they are pricing the risk and the time value of their money. The real skill is in borrowing only for things that earn more than the interest costs, so the debt pays for itself and then some.
A company borrows ₦10,000,000 at 15 percent yearly interest. That is ₦1,500,000 in interest expense for the year, deducted from operating profit before tax is applied, even if the business had a strong year in sales.
Questions people ask
Is interest expense the same as loan repayment?
No. Loan repayment includes paying back the amount you borrowed, called the principal, plus the interest. Interest expense is only the cost portion, the extra amount charged for borrowing, not the return of the original sum.
Does interest expense reduce the tax a company pays?
Often yes. In many tax systems, including Nigeria's, interest expense is deductible before tax is calculated, which lowers the taxable profit. This is one reason some companies prefer debt financing over pure equity.
Where do I find interest expense in a company's accounts?
It appears on the income statement, usually below operating profit and above profit before tax, often listed separately so investors can see how much of the company's earnings are being used to service debt.
