What is a Debt-to-EBITDA Multiple?

The debt-to-EBITDA multiple divides a company's total debt by its yearly earnings before interest, taxes, depreciation and amortization. The result is a time measure: roughly how many years of earnings it would take to pay off every loan. 2x reads as comfortable and 6x reads as risky.

The two ingredients are total debt and EBITDA, a rough stand-in for the cash a business generates in a year before financing costs: $90M of debt on $30M of EBITDA is 3x, meaning three years of everything the company earns just to clear its loans. The number rules lending — banks write it into loan contracts as a covenant, "debt shall not exceed 4.5x EBITDA," a tripwire that can trip from either side: borrow more, or earn less. A company whose EBITDA drops from $30M to $20M jumps from 3x to 4.5x without borrowing a cent. Crossing the line hands the lender power: faster repayment, a higher rate, forced renegotiation, and more detailed and frequent reporting requirements. Rough scale: under 3x most lenders relax, 4–5x is leveraged territory where private equity operates on purpose, above 6x lenders want a very convincing story. One caution: EBITDA ignores real bills — interest itself, taxes, worn-out equipment — so true repayment capacity is thinner than the multiple suggests.

Mortgage math at the bank: some countries cap a mortgage at about 4.5 times yearly salary — the same formula, your debt measured in years of your earnings, so an $80,000 salary borrows up to $360,000. Notice what else it means: get your hours cut to $60,000 and your multiple worsens with no new borrowing at all. That's exactly how a company breaches its covenant in a bad year — not by borrowing, by earning less.
