Debt-to-EBITDA Ratio

Debt-to-EBITDA ratio is a leverage metric that compares a company's total funded debt to its earnings before interest, taxes, depreciation, and amortization (EBITDA). It expresses the number of years it would theoretically take for a business to repay all debt using current operating earnings, assuming no changes in revenue, expenses, or capital structure.

The formula is:

Debt-to-EBITDA Ratio = Total Funded Debt / EBITDA

Total funded debt typically includes term loans, revolving credit balances, capital leases, and other interest-bearing obligations. It generally excludes trade payables and accrued liabilities. EBITDA is calculated from the income statement by adding back interest expense, income tax provision, depreciation, and amortization to net income. Lenders may use trailing twelve-month (TTM) EBITDA, annualized partial-year figures, or pro forma EBITDA that incorporates projected changes from acquisitions or cost reductions.

A lower ratio indicates stronger debt capacity and lower leverage risk. A higher ratio signals that the business carries more debt relative to its cash-generating ability, which increases refinancing risk, limits access to additional capital, and may trigger financial covenant violations in existing credit agreements.

The debt-to-EBITDA ratio is one of the most widely used credit metrics in commercial lending. Banks, SBA lenders, mezzanine funds, and private credit providers all rely on it to assess borrower leverage and set loan terms. For most commercial borrowers, lenders require a maximum debt-to-EBITDA ratio between 3.0x and 4.0x at underwriting, though the acceptable threshold varies by industry, loan type, and deal structure. Highly leveraged transactions such as business acquisitions may be structured at 4.0x to 6.0x with tighter covenant packages to compensate for the additional risk.

Beyond initial underwriting, the ratio is frequently embedded as an ongoing covenant in loan agreements. Borrowers must maintain their debt-to-EBITDA ratio below a specified threshold throughout the life of the loan, typically tested quarterly. Breaching the covenant can trigger a covenant default, which may result in increased pricing, accelerated repayment, or loss of borrowing availability under a credit facility.

Business owners should understand that the ratio is dynamic. Taking on additional debt (including equipment leases or lines of credit) increases the numerator, while declining earnings reduce the denominator. Both movements push the ratio higher. Monitoring debt-to-EBITDA on a rolling basis, rather than only at the time of borrowing, helps businesses anticipate covenant pressure and avoid surprises during lender reporting periods.

• Excluding all debt obligations: Borrowers sometimes calculate the ratio using only their primary term loan while omitting revolving credit balances, capital leases, and subordinated debt. Lenders include all funded interest-bearing obligations in the numerator, which can produce a materially higher ratio than the borrower expected.
• Using unadjusted EBITDA without lender add-backs: Lenders often allow legitimate adjustments to EBITDA, such as owner compensation normalization, one-time legal costs, or non-recurring expenses. Failing to present adjusted EBITDA with documented add-backs can result in a ratio that understates the business's true earning power and leads to unfavorable terms.
• Confusing debt-to-EBITDA with DSCR: The debt service coverage ratio measures the ability to cover annual debt payments from cash flow, while debt-to-EBITDA measures total leverage relative to earnings. A business can have an acceptable DSCR (sufficient cash flow to cover current payments) but an elevated debt-to-EBITDA ratio (too much total debt relative to earnings). Lenders evaluate both metrics independently.
• Ignoring the impact of new debt on the ratio: When seeking additional financing, borrowers often fail to calculate the pro forma debt-to-EBITDA ratio that includes the proposed new debt. If the new obligation pushes the ratio above existing covenant thresholds, the borrower may be in technical default on their current loans before the new facility even closes.
