Interest Coverage Ratio Calculator: EBIT Over Interest Expense
Work out a business's interest coverage ratio — the headline solvency metric that asks whether earnings can comfortably pay the interest bill, or whether one bad year sinks the company.

Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Coverage (times) |
|---|---|
| $200k EBIT · $40k interest | $5.00 |
| $1M EBIT · $250k interest | $4.00 |
| $50k EBIT · $45k interest (stress) | $1.11 |
| $5M EBIT · $400k interest | $12.50 |
How This Calculator Works
Enter EBIT (earnings before interest and tax) and annual interest expense over the same period. The calculator divides one by the other to give the coverage ratio — read it as 'times covered'. The output is formatted as currency; a $5 figure means 5× interest coverage.
The Formula
Cost per Unit
Total Amount is the full cost or price, Quantity is the number of units it covers
Worked Example
A business with $200,000 EBIT and $40,000 of interest expense has 5× interest coverage — earnings cover interest five times over. Lenders typically want at least 2× to 3× on senior debt; below 1.5× signals stress; below 1× means earnings are not covering interest and the business is borrowing to pay interest.
Key Insight
Interest coverage is the cleanest single solvency check. Strong businesses run 5×+; investment-grade companies typically clear 3×; high-yield issuers often sit at 1.5× to 3×. The ratio also explains why a small EBIT drop matters so much for over-levered companies — going from 2× to 1.5× coverage is mathematically modest but commercially severe, and lenders read it as risk.
Frequently Asked Questions
How is interest coverage calculated?
Divide EBIT (earnings before interest and tax) by annual interest expense. $200,000 of EBIT against $40,000 of interest is a 5× coverage ratio.
What is a healthy interest coverage ratio?
Investment-grade companies typically clear 3× to 5×. High-yield (junk) issuers often sit between 1.5× and 3×. Below 1.5× is stress; below 1× means earnings do not cover interest at all.
Why is interest coverage important?
It is the first solvency check creditors use. Earnings can fluctuate; interest expense is contractual. A business with thin interest coverage is one bad quarter away from missing payments.
Should I use EBIT or EBITDA?
EBITDA adds back depreciation and amortization, which gives a higher ratio. EBIT is more conservative because depreciation reflects real capital consumption. Lenders often use EBITDA coverage for cyclical industries with heavy non-cash charges.
Can it be artificially low?
Yes — temporarily low EBIT (one-time charges, restructuring) can sink the ratio in a given year. Read interest coverage as a trend across years, not just a snapshot.

Methodology & Review
Interest coverage is EBIT (earnings before interest and tax) divided by annual interest expense. The output is read as 'times covered' — a value of 5 means earnings cover interest 5 times over. The calculator formats it as currency; interpret $5 as 5× coverage.
