See how comfortably a company can pay the interest on its debt. Enter operating income (EBIT) and interest expense for the interest coverage ratio — add EBITDA for a second, cash-based coverage figure.
Answer first: the interest coverage ratio — also called times interest earned — shows how many times a company's operating profit could cover its annual interest bill. This interest coverage ratio calculator divides EBIT by interest expense, and if you add EBITDA it also gives a cash-based coverage figure that many lenders prefer.
Interest coverage = EBIT ÷ Interest expense
Example: $120M of operating income against a $20M interest bill gives 120 ÷ 20 = 6.0×. The company earns six dollars of operating profit for every dollar of interest it owes — a comfortable cushion. Using $160M of EBITDA instead, coverage rises to 8.0×.
This is one of the most important solvency checks in all of finance, because interest is a non-negotiable, contractual expense. A company can cut its dividend, delay a project or pause hiring, but it must pay its lenders on time or risk default. The interest coverage ratio measures the margin of safety between the profit the business generates and the fixed cost of its debt — the bigger the multiple, the more room to absorb a downturn before those payments become a problem.
As a broad guide, coverage above 3× is generally considered safe, and many strong companies run well into double digits. A ratio between 1.5× and 3× is a yellow flag — the company can pay, but a bad year could erase the cushion. Below 1.5× is a serious warning, and a ratio under 1.0× means operating profit does not even cover the interest, forcing the company to dip into cash reserves, sell assets or borrow more just to service existing debt — a classic distress spiral.
Lenders and analysts often look at both versions. EBIT-based coverage is the stricter measure because EBIT is after depreciation, reflecting the real wearing-out of assets. EBITDA-based coverage is more generous because it adds depreciation back, arguing that non-cash charges do not consume the cash available to pay interest this year. The truth sits between them: EBITDA overstates sustainable cash for capital-hungry businesses that must keep reinvesting, while EBIT can be overly harsh for asset-light firms. Watching both, and their trend, gives the fullest picture of debt safety.
A single year's coverage ratio can be flattered by a one-off gain or depressed by a temporary cost, so the direction of travel is what really counts. Coverage that is steadily falling — whether because profits are shrinking or debt is growing — is a warning long before the ratio hits a dangerous level. It is especially important for cyclical companies, whose profits swing hard with the economy: a comfortable 6× at the top of a cycle can collapse toward 1× in a recession. Pair this ratio with debt-to-equity to see both the size of the debt and the ability to service it.
Reality check: interest coverage uses one period's profit, which can be volatile, and it ignores looming debt maturities. This tool is educational, not investment advice. For company-reporting basics, see the U.S. SEC at investor.gov.
Size up the debt itself with the debt-to-equity calculator, check liquidity with the quick ratio and current ratio calculators, and judge whether borrowing earns its keep with the ROIC calculator.

Broadly, coverage above 3x is considered safe and strong companies often run into double digits. Between 1.5x and 3x is a caution zone, and below 1.5x is a serious warning. Under 1.0x, operating profit cannot even cover the interest.
Times interest earned is another name for the interest coverage ratio: EBIT divided by interest expense. It shows how many times over a company's operating profit could pay its annual interest bill.
EBIT-based coverage is stricter because it is after depreciation. EBITDA-based coverage is more generous because it adds depreciation back. Lenders often look at both; EBITDA can overstate safety for capital-intensive businesses.
A single year can be distorted by one-off items, and cyclical companies' profits swing with the economy. Steadily falling coverage is a warning well before it reaches a dangerous level, so the direction of travel matters more than one reading.
