Interest Coverage Ratio — How Many Times Over Can It Cover Interest?
How do you know whether a heavily indebted company is risky? One simple yardstick is 'how many times over can it pay interest with the money it earns.'
The interest coverage ratio formula
The Interest Coverage Ratio (ICR) is a metric that shows how many times over a company can cover its interest with the profit it earns from operations.
The formula is simple.
Interest Coverage Ratio = Operating Profit (EBIT) ÷ Interest Expense
Here EBIT is earnings before interest and taxes — that is, the money the company earns from its core business. Interest expense is the interest owed on loans, corporate bonds, and the like.
How to interpret it
The larger the number, the more comfortably it can bear the interest burden.
· Interest coverage of 5x → operating profit is 5 times the interest. Quite stable. · 2x → operating profit is 2 times the interest. There is room, but if profit is halved it gets tight. · 1x → operating profit equals the interest. Even a small drop in profit means it cannot even cover interest. · Below 1x → operating profit alone cannot cover the interest. A financial risk signal.
Bond investors and credit rating agencies like to look at this metric when gauging default risk.
Points to watch
The interest coverage ratio is powerful but not all-purpose.
· EBIT is an accounting profit, so it can differ from actual cash flow. Some companies show profit while running dry on cash. · For cyclical industries, the ratio swings wildly between booms and busts. Looking at a single year's number can mislead you. · Interest expense omits other fixed costs such as lease payments, so it can understate the actual repayment burden.
The picture is complete only when you look at it together with other financial ratios and cash flow.
The interest coverage ratio is an educational metric for understanding a company's financial stability. This article does not recommend buying or selling any particular security, and making an investment decision on a single ratio alone is dangerous.
Frequently Asked Questions
Q. If the interest coverage ratio is below 1x, does that automatically mean default?
No. Below 1x is only a warning signal that 'operating profit alone cannot pay the interest.' The company may hold on through its cash reserves, asset sales, refinancing, and so on. That said, if it persists, financial risk is very high.
Q. Do people also use EBITDA instead of EBIT?
Yes. There is also an 'EBITDA interest coverage ratio' calculated with EBITDA, which adds back depreciation and amortization. It looks at cash-generating power more broadly, but it draws criticism for ignoring actual capital expenditures, so it is best to consult it alongside the other.
