Interest cover and affordability: what lenders test

Lenders lend to companies that can comfortably pay. Before advancing funds they test affordability through interest cover and debt service cover — ratios that show how easily profit and cash service the debt. Knowing the thresholds and running them yourself first tells you whether to apply and for how much. Here is what they check.

Interest cover = operating profit / interest payable. Lenders watch it to check profit comfortably covers interest.

The two affordability ratios

Interest cover divides operating profit by the interest bill. Debt service cover divides free cash by total debt service (interest plus capital). Together they show how comfortably you can carry the loan.

The thresholds lenders look for

Many lenders want interest cover of at least 2–3× and debt service cover of at least 1.25×. Below those, the loan looks tight, and the lender either declines, lends less, or prices the extra risk into the margin.

Stress-tested cover

Lenders also test cover at a higher stress rate, not just today’s. A loan that only just passes at current rates may fail the stress test — so borrow with an interest rate buffer.

Frequently asked questions

What interest cover do lenders want?

Often at least 2 to 3 times, meaning profit covers the interest bill twice or three times over. Below that, expect a decline, a smaller loan, or a higher margin.

What is the difference between interest cover and DSCR?

Interest cover looks at profit against interest only. DSCR looks at cash against interest plus capital repayments, so it is a fuller affordability test.

Why stress-test the cover?

Because rates can rise. Lenders test cover at a higher rate so the loan stays affordable if borrowing costs climb. Borrow with a buffer to pass.
