A company can be profitable on paper and still go bankrupt if it cannot pay the interest on its debt. The interest coverage ratio (ICR), also called times interest earned, measures exactly that: how many times over a company's operating profit can cover the interest charges it owes in a given year. Lenders, bond investors, and credit analysts use this single number to decide whether a business is safe, stretched, or in danger of default.
This calculator computes both the Interest Coverage Ratio (ICR) and the more conservative Debt Service Coverage Ratio (DSCR) from your EBIT, annual interest expense, and scheduled principal repayments. Enter the figures from a recent income statement and balance sheet, and the result card tells you instantly how healthy your debt position is.
How to Use
- Enter EBIT — Earnings Before Interest and Taxes. This is operating profit (revenue minus COGS and operating expenses) plus any non-operating income, taken before interest and tax are subtracted. Use the most recent full fiscal year.
- Enter Annual Interest Expense — the total interest paid on all loans, bonds, and credit facilities during the year. This comes directly off the income statement.
- Enter Annual Principal Repayments — the scheduled paydown of loan principal during the year. This is not on the income statement; find it on the cash flow statement under financing activities. Leave it at zero if your debt is interest-only.
- Optionally add Cash & Equivalents for context. It is not used in the ratio itself, but a large cash buffer can offset a thin coverage ratio in practice.
- Read the result card: the ICR is highlighted, the DSCR below it is more conservative because it also counts principal repayment, and the assessment labels the ratio as Strong, Adequate, Weak, Distressed, or Insolvent.
The interest coverage ratio is expressed in "times." An ICR of 3.0 means the company's operating profit covers its interest bill three times over. Lenders generally want to see at least 2.0, and many credit agreements require a minimum ICR of 1.2 or 1.5 as a financial covenant.
The Formulas
The interest coverage ratio is the classic solvency metric taught in every corporate finance course:
ICR = EBIT / Interest Expense
Where EBIT is earnings before interest and taxes. A higher ratio is safer: 4.0 or above is considered strong, 2.0–4.0 is adequate, 1.5–2.0 is weak, and below 1.0 means the company cannot generate enough operating profit to cover its interest bill at all.
The debt service coverage ratio broadens the denominator to include principal repayments, which is what lenders actually care about because they expect both interest and principal to be paid:
DSCR = EBIT / (Interest Expense + Principal Repayments)
DSCR is always equal to or lower than ICR when principal repayment is positive. A DSCR above 1.25 is the typical threshold banks use for commercial loans; below 1.0 means operating cash flow is not enough to service the debt at all.
If interest expense is zero (no debt), the ICR is mathematically undefined — but practically that means the company has no interest burden, so coverage is effectively infinite. The calculator shows "N/A — no debt" in that case rather than dividing by zero. If EBIT is zero or negative, the engine raises an error: you cannot meaningfully compute coverage when the business is losing money.
Why the Ratio Matters
Credit analysts look at ICR because it strips out the noise of capital structure, tax policy, and one-off items. A company with $10 million of EBIT and $2 million of interest expense has an ICR of 5.0 — comfortably able to service its debt even if earnings dip by 80%. A company with the same EBIT but $6 million of interest has an ICR of 1.67: a 40% decline in earnings would leave it unable to pay interest from operations, forcing it to draw cash, sell assets, or refinance.
This is why highly leveraged companies get downgraded by rating agencies the moment their ICR falls below 2.0. Falling ICR predicts default long before net income turns negative.
Examples
Example 1 — A healthy industrial company. EBIT of $1,200,000, interest expense of $400,000, and principal repayments of $100,000. ICR = 1,200,000 / 400,000 = 3.00×, DSCR = 1,200,000 / 500,000 = 2.40×. The assessment reads "Adequate to Strong" — comfortable cushion, room for a downturn.
Example 2 — A leveraged buyout in distress. EBIT of $600,000, interest expense of $500,000, principal of $200,000. ICR = 1.20×, DSCR = 0.86×. The DSCR below 1.0 means the business does not generate enough operating profit to make the full debt payment; it must cover the shortfall from cash reserves or refinancing. Lenders would view this as a high-risk credit.
Example 3 — A large public company. EBIT of $15,000,000, interest of $2,500,000, principal of $1,500,000. ICR = 6.00×, DSCR = 3.75×. This is a strong investment-grade profile: earnings would have to fall by more than 80% before interest became a problem.
Example 4 — No debt at all. EBIT of $500,000, interest expense of $0, principal of $0. Both ratios show "N/A — no debt." The company is entirely equity-financed and has no coverage risk, though it may be leaving cheap tax-deductible leverage on the table.
FAQ
What is a good interest coverage ratio?
A ratio of 2.0 or higher is generally considered safe, 4.0 or above is strong, and anything below 1.5 signals that the business is thinly cushioned against a downturn. A ratio below 1.0 means operating profit does not even cover the interest bill, which is a default warning sign.
What is the difference between ICR and DSCR?
ICR divides EBIT by interest expense only. DSCR divides EBIT by interest expense plus scheduled principal repayments. ICR is the classic accounting metric; DSCR is what banks actually underwrite against, because loans require both interest and principal to be paid. DSCR is always equal to or lower than ICR when principal is positive.
Should I use EBIT or EBITDA in the numerator?
The textbook ICR uses EBIT. Some lenders prefer EBITDA (adding back depreciation and amortization) because D&A is a non-cash charge and the business needs cash, not accounting profit, to pay interest. The difference matters most for capital-intensive industries like airlines or manufacturing. This calculator uses EBIT, the standard definition; if your lender uses EBITDA, simply add D&A to your EBIT input.
What does it mean if my interest coverage ratio is below 1.0?
An ICR below 1.0 means operating profit is not sufficient to cover the annual interest expense. The company must cover the gap from cash reserves, asset sales, or new borrowing. If this persists, it is a leading indicator of default, restructuring, or bankruptcy.
How does the interest coverage ratio affect my credit rating?
Rating agencies treat ICR as a primary input. S&P and Moody's assign investment-grade ratings (BBB- or higher) to companies sustaining ICR above roughly 4.0–5.0 for industrial firms. Ratios between 2.0 and 4.0 usually map to the BBB/BB range, and below 2.0 is speculative-grade or "junk" territory.
Can I have too high an interest coverage ratio?
A very high ICR (say above 10×) usually means the company is under-leveraged. It is safe, but it may be passing up the tax shield from deductible interest and the higher returns to shareholders that moderate leverage can provide. Too much safety can itself be a sign of conservative, perhaps suboptimal, capital structure.
