Leverage and Coverage Ratios Bankers Use

Introduction

At the end of 2025, Charter Communications, then the second-largest US cable operator, owed $94.6 billion in principal. Its net debt was 4.15 times its last twelve months of adjusted earnings before interest, taxes, depreciation and amortization (EBITDA), inside the 4.0 to 4.5 times range it had targeted for years, a level that would alarm investors in most industries but that cable companies sustain because their subscription revenue is steady. Its adjusted EBITDA of $22.7 billion covered its net interest expense about 4.5 times. But Charter also spent $11.7 billion on capital expenditure that year, and after that spending, its earnings covered interest only about 2.2 times, as its 2025 annual report shows.

Leverage and coverage ratios are the core of credit analysis and of debt financing work. They decide how much a company can borrow, what it pays, which covenants it accepts and how rating agencies classify it. They are also built on definitions, of debt, of EBITDA and of interest, that vary between companies, lenders and agencies, which is why reading them well means reading the definition first.

The most common leverage measure is debt to EBITDA: total debt divided by last twelve months EBITDA. It approximates how many years of operating cash flow, before capital spending, taxes and interest, it would take to repay the debt. Net leverage subtracts cash from debt first, on the logic that cash could repay part of the debt immediately.

Net leverage

Total debt less cash and cash equivalents, divided by EBITDA for the last twelve months, usually adjusted for one-off items and, after acquisitions, presented pro forma for the full year. It is the most widely used measure of a company's indebtedness in leveraged finance, rating analysis and corporate leverage targets.

Other leverage measures use the balance sheet. Debt to capitalization divides debt by debt plus equity, and debt to equity compares the two directly. Both use book values, which buybacks, losses and acquisition accounting can distort, so bankers usually prefer earnings-based measures for companies with meaningful EBITDA and market-value measures, such as debt to enterprise value, when assessing how much of a company's value belongs to its lenders.

What Level Is High

There is no single safe level of leverage; it depends on how stable the cash flows are. Cable, tower and utility companies, whose revenue comes from contracts or subscriptions, routinely run at four times EBITDA or more, while cyclical businesses whose earnings can halve in a downturn usually stay far lower. Home Depot's net leverage, about 2.2 times at the end of its 2025 fiscal year on the figures in its fiscal 2025 annual report, is moderate for a retailer after two debt-funded acquisitions, and Costco's fiscal 2026 annual report shows more cash than debt. Comparing a company's leverage with that of peers with similar earnings stability, and with the thresholds the rating agencies apply to its sector, says more than any general rule.

What Counts as Debt

The numerator needs as much care as the denominator. Bonds, loans, commercial paper and finance leases are debt. Operating lease liabilities, unfunded pension obligations, preferred stock and certain guarantees may or may not be included, depending on who is calculating the ratio. Rating agencies typically add leases and pension deficits to reported debt; credit agreements usually do not; and companies' own targets follow their own definitions. The components and their treatment are described in debt on the balance sheet.

Secured and Senior Leverage

Lenders also measure leverage through each layer of the capital structure. First-lien leverage counts only the debt secured on a first-priority basis; senior leverage counts debt ranking ahead of subordinated notes. Charter manages its first-lien debt at the level of its operating subsidiary to stay at or below 3.5 times adjusted EBITDA, alongside its total leverage target. The layers matter because recoveries in a default depend on them, and because many credit agreements limit borrowing at each level separately.

Coverage ratios turn the comparison around: they divide earnings by the fixed charges the earnings must cover. Interest coverage, EBITDA or earnings before interest and taxes (EBIT) divided by interest expense, is the simplest. EBITDA coverage shows the cash earnings available before capital spending; EBIT coverage charges depreciation as a proxy for the investment needed to keep the business running. For capital-intensive businesses, the difference is large, and a measure that deducts actual capital expenditure is more telling. Charter's figures show the range:

Charter's adjusted EBITDA excludes $673 million of stock-based compensation, among other items; deducting that cost would raise its net leverage to about 4.3 times. The last line, free cash flow to debt, is the measure closest to the question lenders ultimately ask: how much of the debt the business could repay each year from the cash it actually generates.

Fixed Charge Coverage

The fixed charge coverage ratio widens the denominator to include other unavoidable payments. In asset-based lending, the usual definition is EBITDA less unfinanced capital expenditure and cash taxes, divided by cash interest plus scheduled principal repayments, and sometimes dividends and lease payments. Asset-based revolving facilities commonly contain a springing covenant requiring a ratio of at least 1.0 times, tested only when the borrower's availability under the facility falls below a set threshold. Retailers and other companies with large leases often use a variant that adds rent to both earnings and charges, the logic behind EBITDAR (EBITDA before rent).

Fixed charge coverage ratio

A measure of whether a borrower's earnings cover its unavoidable cash obligations, commonly EBITDA less unfinanced capital expenditure and cash taxes, divided by cash interest and scheduled principal repayments, with lease payments and dividends sometimes included. Definitions are set in each credit agreement and differ from deal to deal.

The EBITDA in a credit agreement is rarely the EBITDA in the financial statements. Credit agreements define consolidated EBITDA with add-backs for restructuring costs, transaction expenses, non-cash charges and, frequently, expected cost savings and synergies from acquisitions, usually capped as a share of EBITDA and limited to a period after the action is taken. Many also cap how much cash can be netted against debt. The result can be a covenant leverage ratio well below the one an analyst would calculate from reported figures, a gap examined in non-GAAP measures and in the covenant section of quality of earnings.

Covenants themselves come in two forms. Maintenance covenants, common in bank loans and private credit, must be met every quarter. Incurrence covenants, standard in high-yield bonds and most broadly syndicated loans, apply only when the company takes an action such as borrowing more, paying a dividend or making an acquisition. Many loans also tie the interest margin to leverage through a pricing grid, so that the cost of debt falls as leverage does.

Rating agencies take the opposite approach to adjustments, adding debt-like obligations that companies leave out. Their adjusted debt typically includes lease liabilities and pension deficits, and their EBITDA is adjusted to match: operating lease costs are reclassified as depreciation and interest, so they no longer reduce EBITDA. A company's leverage on the agencies' definitions can therefore be noticeably higher than on its own.

In leveraged finance, debt capacity is set as a multiple of EBITDA: the amount lenders will provide for a buyout or recapitalization depends on the leverage and coverage the business can support, and those multiples move with credit markets. In acquisition financing, bankers calculate leverage pro forma for the deal, combining both companies' EBITDA and the new debt, as part of the sources and uses of funds. Charter completed its combination with Cox Communications in August 2026 and had said it would lower its target range to 3.5 to 3.75 times afterwards, the kind of commitment rating agencies weigh when a deal adds debt.

Coverage completes the picture. A company with modest leverage but thin coverage, because its debt carries high interest rates, can be under more strain than one with higher leverage at low rates. Short-term obligations and access to cash, the subject of liquidity ratios, decide whether that strain becomes a crisis. Together, leverage, coverage and liquidity answer the three questions every lender asks: how much is owed, can it be serviced, and can it be refinanced.
