Times Interest Earned (TIE) Calculator

Compute the Times Interest Earned (TIE) ratio using EBIT and interest expense to assess how comfortably a company can cover its interest payments.

$

Operating profit before interest and income taxes for the period. Use the same period as your interest expense (typically the last fiscal year or trailing twelve months).

$

Total interest expense on debt for the same period as EBIT. Excludes principal repayments. Must be greater than 0 for a valid TIE ratio.

What is Times Interest Earned (TIE)?

Times Interest Earned (TIE)—also called the Interest Coverage Ratio—measures how many times a company’s EBIT (operating profit) can cover its interest expense in the same period.

It matters because it’s a core signal of credit risk: stronger coverage typically supports better credit ratings, a lower cost of debt, and more flexibility in capital structure decisions.

Weak coverage raises default risk, tightens covenants, and can increase WACC, reducing value creation and limiting reinvestment into growth.

Formula

TIE = EBIT / Interest Expense

Example

  • EBIT: $250,000
  • Interest Expense: $50,000

Calculations:

TIE = 250,000 / 50,000 = 5.0x
  • Earnings Buffer (EBIT − Interest Expense): $200,000

Interpretation:

  • TIE = 5.0x indicates strong interest coverage in many corporate finance contexts, implying meaningful headroom before interest becomes a constraint on operating decisions, free cash flow, and refinancing.

Frequently Asked Questions

What numbers should I use for EBIT and Interest Expense (annual, quarterly, or TTM)?

Use the same period for both—most people use annual or trailing-twelve-months (TTM) from the income statement. Mixing periods (e.g., quarterly EBIT with annual interest) makes the ratio meaningless.

Should I use EBIT or EBITDA for Times Interest Earned (TIE)?

Classic TIE uses EBIT because it reflects operating profit before financing costs. If your industry focuses on EBITDA/Interest, use that as a separate “EBITDA coverage” metric—don’t call it TIE.

What’s a “good” TIE ratio for lenders and covenants?

Higher is better, but “good” depends on business volatility and industry. As a practical rule: below ~1.5x is usually tight, ~2–3x is watchable, and 4x+ is often viewed as strong—unless the business is cyclical or earnings are unstable.

What if Interest Expense is zero or EBIT is negative?

If interest is zero, TIE is not meaningful (coverage is effectively “not applicable” because there’s nothing to cover). If EBIT is negative, TIE will be negative—treat it as a red flag and focus on cash runway, debt terms, and whether interest will be funded from cash rather than operations.
