Why times interest earned (TIE) matters to a first-time founder
The ratio shows how much operating profit cushions a company’s interest bill. A low or falling result can signal refinancing pressure before cash runs out, while lenders may require a minimum level. Founders can use it to test whether new borrowing remains affordable when profit or rates move.
Examples of times interest earned (TIE)
A company reports €240,000 of EBIT and €60,000 of interest expense, giving TIE of 4.0. If operating profit falls to €90,000 after losing a customer, coverage drops to 1.5. The founder models that downside before taking another loan whose interest would add €20,000 annually.
Common misunderstanding
TIE does not show whether cash is available on the payment date. EBIT includes non-cash accounting items and excludes principal repayments, tax and capital spending. It also differs from debt service coverage, which usually compares a cash-flow measure with both interest and scheduled principal, although lender definitions vary.
When to use it
Use TIE when reviewing debt capacity, lender covenants or changes in interest rates. Calculate it consistently across periods and inspect one-off profit or interest items. Read the loan agreement’s exact definition because it may adjust EBIT, capitalised interest or leases, and obtain advice before relying on covenant headroom.
