Interest Coverage Ratio Calculator
From EBIT and interest expense, compute the interest coverage ratio to gauge a company's ability to pay interest.

At a glance:The interest coverage ratio (EBIT ÷ interest expense) measures how many times a company's operating profit covers its borrowing interest — one of the most important solvency indicators. Higher is safer (generally 2.5–3+ is sound); lower is riskier — below 1.5 means thin buffer, below 1 means operating profit cannot cover interest, a serious warning. Example: EBIT 300,000, interest 60,000 → ratio = 5×, ample buffer even if earnings fall. It is an income-statement flow indicator, more directly reflecting current interest-paying ability than balance-sheet stock indicators.
Formula
Interest coverage ratio = EBIT ÷ interest expense.
$$\text{Interest Coverage Ratio} = \dfrac{\text{EBIT}}{\text{Interest Expense}}$$How to Use
- Enter EBIT from the income statement.
- Enter the period's total interest expense.
- View the interest coverage ratio (how many times profit covers interest).
With interest expense fixed at HK$60,000, coverage as EBIT rises from 60k to 300k
| EBIT (HK$) | Interest (HK$) | Coverage | Safety read |
|---|---|---|---|
| 60,000 | 60,000 | 1.0× | Danger: profit just covers interest |
| 90,000 | 60,000 | 1.5× | Tight: thin buffer |
| 150,000 | 60,000 | 2.5× | Reasonably sound |
| 300,000 | 60,000 | 5.0× | Safe: ample buffer |
Case Studies
Case 1: Cyclical industries need a higher buffer
Mr Chan analyses a HK cyclical company (e.g. shipping/property development): in a boom EBIT is 300,000, interest 60,000, coverage 5×, seemingly very safe.
But at the cycle trough with earnings slashed, EBIT falls to 75,000 and coverage drops to 1.25× (75,000 ÷ 60,000), buffer nearly exhausted. This shows for volatile-earnings industries you must not look only at the boom-time high ratio, but use 'the ratio sustainable at the trough' as the margin; stable rent-collecting or utilities are relatively safe even at moderate ratios, while cyclical stocks need a higher coverage to be sound.
Case 2: EBIT vs EBITDA definitions
Another capital-intensive telecom has EBIT 150,000, interest 60,000, standard coverage 2.5×. But it has large non-cash depreciation/amortisation of 90,000 per year.
Using EBITDA (EBIT + D&A = 150,000 + 90,000 = 240,000) as numerator, coverage rises to 4× (240,000 ÷ 60,000). Since D&A involves no actual cash outflow, the EBITDA basis better reflects cash available for interest, more reasonable for asset-heavy industries. When reading research or comparing peers, first clarify whether they use EBIT or EBITDA, otherwise the ratios are not directly comparable. This calculator uses the standard EBIT basis.
FAQ
How high is a safe interest coverage ratio?
Generally higher is safer. Common thresholds: 2.5–3+ is sound (ample buffer even if earnings drop); 1.5–2.5 is moderately tight (watch earnings stability); below 1.5 means operating profit barely covers interest with thin buffer, and a downturn or rate rise could cause payment difficulty; below 1 is a clear danger — current operating profit cannot cover interest, requiring reserves, asset sales or new borrowing, i.e. high default risk. But these are rules of thumb; the real 'safety line' depends on earnings stability and industry. Stable, predictable earnings (utilities, rent-collecting property) are safe even at moderate ratios; volatile cyclical industries (commodities, shipping, development) need a higher ratio as margin for troughs. Judge with earnings volatility, industry cycle and historical trend, not a single number.
Why use EBIT rather than net profit?
Because the ratio measures 'can earnings pay interest', and the earnings used should logically be 'before interest' — that is EBIT. The income statement flows: revenue minus operating costs = EBIT, then minus interest = profit before tax, then minus tax = net profit. Using net profit as the numerator would measure 'ability to pay interest' with a number already after interest is deducted — logically backwards, since interest is the very object we assess. EBIT purely reflects 'core operating profit relative to interest burden'. Tax is also after interest (and interest is usually tax-deductible), so not deducted here either. Some analysts use EBITDA (EBIT plus back depreciation/amortisation, non-cash) as numerator since D&A involves no cash outflow, giving a cash-closer, higher ratio. Whether to use EBIT or EBITDA depends on purpose and industry. This calculator uses the standard EBIT ÷ interest expense.
When interest expense is zero, is the ratio meaningful?
Mathematically it becomes division by zero (tends to infinity); this calculator shows 0 to avoid error, but that does NOT mean 'zero solvency' — quite the opposite. Zero interest expense usually means the company has almost no borrowing, i.e. zero or very low leverage. Then there is no interest burden and no risk of failing to pay, so the indicator loses meaning for it. For a debt-free company, use other angles: cash-flow adequacy, profitability (net margin, ROE), or whether it is too conservative. Conversely, as long as there is real interest expense, the ratio is very useful. Enter the true interest expense if the company borrows; if zero, the indicator is not analytically meaningful for it.
How to combine interest coverage with the debt-to-equity ratio?
They are the most common pair for debt risk, answering 'how much borrowed' and 'can it cope' respectively. D/E = total liabilities ÷ equity is a balance-sheet stock/structure indicator of overall leverage; interest coverage = EBIT ÷ interest expense is an income-statement flow/ability indicator of current interest-paying ability. Looking at only one can mislead: a high D/E company may be fine if earnings are stable and coverage high (6–7×) — high leverage amplifies returns, not necessarily dangerous (e.g. stable rental property); conversely a moderate D/E company with thin earnings and coverage below 1.5 may still struggle. So view both: D/E for leverage scale, coverage for interest-paying ability, plus operating cash-flow stability, for a full picture. Pair with this site's debt-to-equity calculator.
How can HK SMEs improve their interest coverage ratio?
Since ratio = EBIT ÷ interest expense, improve by raising the numerator (EBIT) or lowering the denominator (interest). For HK SMEs: raise EBIT by reviewing gross and operating margins — optimise pricing, control material/labour costs, cut long-loss product lines or branches; improve operating efficiency and speed up inventory and receivables turnover. Lower interest by refinancing high-rate debt with lower-rate loans, using government/bank SME low-interest and guarantee schemes, negotiating better rates/terms with banks, or using operating cash flow to prepay high-rate debt. Also avoid over-borrowing and arrange debt maturities sensibly (reduce near-term refinancing pressure). The healthiest improvement is growing core earnings, not just cost-cutting or over-contracting. For specific financing and tax, consult an accountant, bank RM or professional adviser.
