What it means
The ratio, also called interest cover, answers a lender's most basic question: if trading gets worse, how far can it fall before this borrower cannot pay us? A result of 6.0 means operating profit could drop by more than 80% before interest became unaffordable, whereas a result of 1.5 means there is almost no margin for a bad quarter.
Interest cover matters more than the size of the debt itself, which is the point non-finance managers most often miss. A company with $50,000,000 of borrowings and strong profits may be far safer than one with $5,000,000 of borrowings and volatile earnings, because affordability rather than absolute debt determines whether payments get made.
The measure uses earnings before interest and tax rather than net profit, and the logic is deliberate. Interest is paid out of profit before tax and before the interest deduction itself, so using a post-interest figure would double-count the very cost you are testing.
Bank loan agreements typically require interest cover to stay above a stated level, often somewhere between 2.0 and 4.0, tested every quarter. Breaching that covenant is a technical default, which can allow the lender to demand repayment or reprice the facility even if every payment has been made on time.
The main limitation is that operating profit is not cash. A business can report healthy earnings while cash is trapped in inventory and unpaid invoices, which is why many lenders now use a cash-based variant such as EBITDA divided by interest, or a debt service ratio that includes capital repayments as well.
In practice
Real-world examples.
Example
A family owned hotel group with interest cover of 5.4 approaches its bank for expansion funding. The bank models the new debt, sees cover falling to 2.8 against a 2.5 covenant, and approves a smaller facility than requested.
Example
A manufacturer's interest cover falls from 4.1 to 1.9 after a customer insolvency wipes out a quarter of its operating profit. The finance director negotiates a covenant waiver before the quarterly test date rather than after it.
Example
A private equity backed retailer runs deliberately at interest cover of around 2.2 following a leveraged buyout. Management monitors it monthly, because a single weak trading month can push the rolling twelve month figure below the covenant.
Think of it
“Times interest earned is like counting how many months of expenses your savings could cover-more is always better.
Formula
Calculation
Times interest earned = Earnings before interest and tax / Interest expense
A regional logistics company reports operating profit, meaning earnings before interest and tax, of $4,500,000 for the year. Its interest expense on bank loans and finance leases totals $750,000.
Times interest earned = $4,500,000 / $750,000 = 6.0, so operating profit covers the interest bill six times over. Profit before tax is therefore $4,500,000 - $750,000 = $3,750,000, and at a 25% tax rate the charge is $3,750,000 x 0.25 = $937,500, leaving net profit of $3,750,000 - $937,500 = $2,812,500.
If the company borrowed a further $10,000,000 at 7.5%, interest would rise by $10,000,000 x 0.075 = $750,000 to $1,500,000. Assuming operating profit was unchanged, interest cover would halve to $4,500,000 / $1,500,000 = 3.0, which is where many bank covenants start to bite.Case study
Seen in the real world.
The following is an illustrative and entirely fictional example. Belfour Foods, an invented chilled ready meals producer, borrowed $18,000,000 to build a second production site, taking its annual interest bill to $1,440,000 against operating profit of $5,040,000. Interest cover of 3.5 sat comfortably above the 2.5 covenant in its facility agreement.
Two things then went wrong at once in this fictional scenario. A major supermarket customer moved a private label contract elsewhere, and energy costs rose sharply, together cutting operating profit to $3,200,000 and dropping interest cover to about 2.2.
Belfour's illustrative management team went to the bank three weeks before the quarterly test with a costed recovery plan, a temporary halt to capital spending and a shareholder commitment to inject $1,500,000. The bank reset the covenant to 2.0 for four quarters in exchange for a higher margin, and the company avoided a default it would almost certainly have suffered had it waited for the test to fail.
Watch out
Common mistakes.
- Using net profit instead of earnings before interest and tax, which understates cover because interest and tax have already been deducted.
- Treating a high ratio as proof of safety without checking whether the profit converts into cash within the year.
- Calculating cover only at the year end, when loan covenants are usually tested quarterly on a rolling twelve month basis.
Questions
People also ask.
What is a good times interest earned ratio?
It depends on the industry, but cover above 3.0 is generally comfortable, between 1.5 and 3.0 warrants attention, and below 1.5 signals genuine stress.
Should lease payments be included in the interest figure?
The interest element of finance leases normally is, and many lenders use a wider debt service cover ratio that captures capital repayments and lease rentals as well.
What happens if a company breaches its interest cover covenant?
It is a technical default, so the lender can demand repayment, raise the margin or impose conditions, which is why borrowers approach the bank early rather than waiting.
