Times Interest Earned Calculator
The times interest earned (TIE) ratio, also known as the interest coverage ratio, tells you how many times over a company can pay its interest costs from operating income. Lenders and bond investors use it to gauge default risk: the higher the ratio, the larger the cushion between earnings and the fixed interest the firm must pay. This calculator takes your earnings before interest and taxes (EBIT) and your annual interest expense and returns the TIE ratio, the surplus earnings remaining after interest, and an at-a-glance read on whether coverage is strong, adequate, or stretched.
Times interest earned formula
TIE ratio = EBIT / interest expense
Earnings after interest = EBIT - interest expense
EBIT is operating income before financing and tax. Dividing it by interest expense gives the number of times the firm could pay its interest from current operating earnings.
How to interpret the TIE ratio
- Above 3.0: strong coverage, low near-term default risk on interest.
- Between 1.5 and 3.0: adequate, but watch for earnings volatility.
- Below 1.5: thin cushion; a downturn could threaten interest payments.
- Below 1.0: operating income does not cover interest at all.
- Use a multi-year trend, not a single period, since one-off items distort EBIT.
Times interest earned: frequently asked questions
What is the times interest earned ratio?
The times interest earned (TIE) ratio, also called the interest coverage ratio, measures how many times a company's operating income (EBIT) can cover its interest expense. A TIE of 5.0 means EBIT is five times the interest the company owes, indicating a comfortable margin of safety.
How is the TIE ratio calculated?
TIE equals EBIT divided by interest expense, where EBIT is earnings before interest and taxes. For example, EBIT of US$500,000 and interest expense of US$100,000 gives a TIE of 5.0. Some analysts use EBITDA instead of EBIT for a cash-focused view.
What is a good times interest earned ratio?
A TIE above 2.5 to 3.0 is generally considered healthy, signalling the firm earns well above its interest obligations. A ratio below 1.5 raises concern, and below 1.0 means operating income cannot cover interest at all. Appropriate levels vary by industry and earnings stability.
What does a negative TIE ratio mean?
A negative TIE ratio occurs when EBIT is negative, meaning the company posted an operating loss. In that case it cannot cover any interest from operations and must rely on cash reserves, asset sales, or new financing to meet its obligations.
How does TIE differ from the debt service coverage ratio?
TIE covers only interest expense. The debt service coverage ratio (DSCR) covers both interest and principal repayments due in the period, giving a fuller view of a borrower's ability to meet total debt obligations. Lenders often look at both.
