What Is the Debt-to-EBITDA Ratio?
The debt-to-EBITDA ratio divides a company's total debt by its earnings before interest, taxes, depreciation, and amortization. A company with 600 million dollars of debt and 150 million of EBITDA carries leverage of 4.0x, meaning it would take roughly four years of current earnings to retire the debt if every dollar of EBITDA went to repayment.
A widely used variant is net debt-to-EBITDA, which subtracts cash and equivalents from debt on the theory that cash on hand could immediately pay down borrowings. Credit agreements often define further versions, including senior leverage, first lien leverage, secured leverage, and total leverage, each measuring debt at a different layer of the capital structure.
How to Interpret It
Context sets the benchmarks. Investment grade industrial companies generally operate below about 3.0x, while leveraged buyouts have historically been financed at 5.0x to 6.0x total debt-to-EBITDA. Stable software and infrastructure businesses can sustain more leverage than cyclical manufacturers because their earnings hold up better in downturns, which is exactly what lenders underwrite to.
The ratio's popularity invites manipulation. Sponsors and borrowers market deals on adjusted EBITDA, layering in add-backs for one-time costs and projected synergies that can flatter leverage by a full turn or more. EBITDA also ignores capital expenditures and working capital needs, so two companies at identical leverage can face very different real repayment burdens.
Why It Matters
Debt-to-EBITDA is embedded throughout the credit markets. Rating agencies anchor their thresholds to it, and covenants in both loans and bonds key off it. US bank regulators have also used 6.0x as a screening level in leveraged lending guidance, which shaped how much debt banks were willing to underwrite and pushed the most aggressive deals toward private credit.
For candidates, the ratio is unavoidable. Paper LBO exercises typically start by applying a leverage multiple to entry EBITDA, and credit interviews ask what leverage a given business can support. Pairing the ratio with interest coverage gives a fuller picture, since debt-to-EBITDA measures the size of the debt burden while coverage measures the ability to service it.
