  11. Summary

The interest coverage ratio tells you how many times a company's operating profit could pay its annual interest bill. Divide earnings before interest and taxes (EBIT) by interest expense: a result of 5× means profit covers interest five times over; 1× means every dollar of operating profit goes to lenders; below 1× means the company cannot meet its interest from operations at all. It is also called times interest earned.

Coverage complements the Debt-to-equity ratio: formula, versions and when it misleads. D/E measures how much is owed against book equity; coverage measures whether the business earns enough to carry that debt each year. A company can have a frightening D/E and comfortable coverage (low interest rates, strong earnings), or a modest D/E and thin coverage (weak earnings, expensive debt). Lenders and credit-rating agencies lean heavily on coverage because interest is the first claim on operating profit and missing a payment is how most defaults begin.

This page computes Apple Inc.'s coverage for fiscal 2021 to 2023, explains why fiscal 2023 is the last year it can be computed directly from Apple's filings, shows the EBITDA and fixed-charge variants, and walks through what thin coverage looks like and how lenders write it into loan agreements.

The formula

Most analysts use operating income from the Income statement: how to read one line by line, with Apple as EBIT. A stricter version uses pretax income plus interest expense, which also counts non-operating gains and losses. For most companies the two are close.

Why fiscal 2023 is the last direct reading

Apple's filings through fiscal 2023 disclosed interest expense as a separate figure (it is tagged InterestExpense in the XBRL data). The fiscal 2024 and fiscal 2025 reports no longer break it out. Between operating income and pretax income, the income statement shows only "Other income/(expense), net", which was (321) million in fiscal 2025. So the textbook ratio can't be computed from Apple's latest statements without an estimate.

Two clues in the fiscal 2025 10-K give a sense of scale, but neither is interest expense:

  • Scheduled interest on the notes. Apple reports $37.0 billion of future interest payments on its notes, $2.6 billion of it due within 12 months. Using that as a rough stand-in, fiscal 2025 operating income of 133,050 ÷ 2,600 ≈ 51×. It excludes commercial paper and the effect of interest-rate swaps, so treat it only as an order of magnitude.
  • Rate sensitivity. Apple estimates that a 100-basis-point rise in rates across all tenors would increase annual interest expense on its term debt by $129 million, showing that part of its fixed-rate debt behaves like floating-rate debt through swaps.

When a company stops disclosing a number you need, you can estimate it, use a data provider's figure, or switch metrics, but always label the result as an estimate.

Coverage over time

Apple, fiscal year Operating income ($M) Interest expense ($M) Coverage
2021 108,949 2,645 41.2×
2022 119,437 2,931 40.7×
2023 114,301 3,933 29.1×

Between fiscal 2022 and 2023 Apple's operating income fell 4.3% and its interest expense rose 34.2%, so coverage dropped by more than a quarter. That rise came during a period of sharply higher US short-term interest rates, which raise the cost of commercial paper and swapped debt. The lesson is general: coverage depends on the price of debt as well as its amount, so a company with floating-rate or short-dated debt can see coverage fall without borrowing another dollar.

Variants

EBITDA coverage

Depreciation and amortization are non-cash charges, so some lenders measure coverage on EBITDA: what it means, how to calculate it and its limits, which gives a higher number.

EBITDA coverage flatters capital-intensive companies whose equipment must be replaced: the cash for new equipment is real even if depreciation isn't a cash cost. For an asset-light company like Apple, the gap between EBIT and EBITDA coverage is small.

Fixed-charge coverage

Leases are fixed obligations much like interest. Fixed-charge coverage adds lease payments (and sometimes other fixed charges) to both the numerator and the denominator:

For retailers and airlines, which lease stores and aircraft, the fixed-charge version can be far lower than plain interest coverage and is the one lenders watch.

How lenders use coverage

Bank loans and private credit agreements commonly include financial covenants: promises the borrower makes to keep certain ratios within limits, tested each quarter. A typical maintenance covenant might require interest coverage of at least a stated multiple, along with a maximum debt/EBITDA. The definitions are written into each agreement (what counts as EBITDA, which add-backs are allowed), so the "covenant coverage" can differ from the figure you compute from the income statement.

If a borrower breaches a covenant, the agreement typically gives lenders the right to declare a default, demand faster repayment, or charge for a waiver. Investment-grade bonds of large companies often carry few or no financial maintenance covenants, while leveraged loans and smaller borrowers usually carry more. Companies describe material covenants and their compliance in the debt notes and the liquidity section of MD&A in their 10-K.

Credit-rating agencies also use coverage, alongside leverage and cash-flow measures, when assigning ratings. As a loose rule of thumb, coverage above about 8× to 10× is associated with strong credit, and coverage below about 2× with highly speculative credit. Those ranges vary by industry and agency and are not fixed thresholds.

What thin coverage looks like

Signs to watch alongside the ratio: coverage falling for several years in a row, interest paid in kind (added to the loan instead of paid in cash), large maturities approaching, and rising use of credit lines. The Current ratio and quick ratio: measuring short-term liquidity page covers the short-term liquidity side of the same risk.

Pitfalls

  • One-off items in EBIT. Restructuring charges or asset gains can swing EBIT in one year. Use a normalized figure, or average several years.
  • Capitalized interest. Companies building large projects may capitalize interest into the asset's cost, so reported interest expense understates the true interest burden.
  • Gross versus net interest. Cash-rich companies earn interest income too. Net interest coverage can be very high or even negative (net income from interest), which isn't meaningful.
  • Cash versus accrual. Interest expense includes amortization of discounts and hedging adjustments; cash interest paid can differ. Apple paid $3,803 million of interest in cash in fiscal 2023 against $3,933 million of expense.
  • Missing disclosure. As with Apple after fiscal 2023, a company may fold interest into a net line. Don't treat a data provider's estimate as a reported figure.

Comparison: coverage and leverage measures

Measure Formula Apple Strength
Interest coverage EBIT ÷ interest expense 29.1× (FY2023) Simple test of interest capacity
EBITDA coverage EBITDA ÷ interest expense 32.0× (FY2023) Closer to cash earnings
Fixed-charge coverage (EBIT + leases) ÷ (interest + leases) ≈26× (FY2025, rough) Captures lease burden
Debt/EBITDA Total debt ÷ EBITDA 0.68× (FY2025) Years of earnings to repay
Debt/equity Total debt ÷ equity 1.34 (FY2025) Capital-structure snapshot

How Finabase does it

The Valuation tab shows Interest Coverage in its Financial Health group as a ten-year annual chart from FMP data, next to Debt / Equity and Net Debt / EBITDA. For fiscal years after Apple stopped disclosing interest expense, the provider's figure rests on its own estimate or definition, so treat those years with care and compare them with the fiscal 2023 reading above.

The Financials tab includes EBIT, Operating Income and an Interest Expense row. A line appears only when the newest period has a non-zero value, so for a company like Apple that no longer reports interest separately the row may be missing. Click any row to chart its history. The screener doesn't filter on coverage.

Frequently asked questions

What is a good interest coverage ratio?

Higher is safer. As a rough guide, coverage above about 8× is seen as comfortable for most industries, and below about 2× signals a company with little room for an earnings decline. Lenders set their own minimums in covenants.

What does an interest coverage ratio below 1 mean?

It means operating profit doesn't cover interest expense. The company has to use cash reserves, borrow more or sell assets to pay its lenders, which can't last.

Why can't I find Apple's interest expense for fiscal 2024 or 2025?

Apple stopped disclosing interest expense as a separate figure after fiscal 2023. Between operating and pretax income its statements show only "Other income/(expense), net". Fiscal 2023's 29.1× is the last coverage you can compute directly from its filings.

Is EBITDA coverage better than EBIT coverage?

EBITDA coverage is closer to cash earnings, but it ignores the cost of replacing worn-out assets. EBIT coverage is the more conservative test. Look at both for capital-heavy companies.

Summary

Interest coverage divides EBIT by interest expense to show how many times operating profit covers the interest bill. Apple's 29.1× in fiscal 2023, the last year it reported interest expense separately, is very high; it was above 40× in fiscal 2021 and 2022 before rising rates lifted its interest costs. EBITDA and fixed-charge versions widen or tighten the test, and lenders write their own definitions into covenants. For any company, read coverage over several years, check how much of its debt reprices with rates, and pair it with debt/EBITDA and the maturity schedule before judging how safe the debt is.
