The interest coverage ratio (also called the Times Interest Earned ratio) is calculated as EBIT or EBITDA divided by interest expense. It answers: how many times over can the company cover its annual interest payments from operating earnings? A ratio of 3.0x means the company generates three times more operating income than required to pay its interest bill. Lower ratios signal credit stress; ratios above 5x indicate strong debt service capacity and characterize investment-grade borrowers. EBIT-based interest coverage is the more conservative measure used by bond rating agencies, as it reflects interest coverage after accounting for non-cash expenses like D&A. EBITDA-based coverage is more generous and is the basis for most leveraged loan covenants in PE transactions, where the interest coverage minimum is typically set at 1.5–2.5x at transaction close. The difference matters most for capital-intensive businesses where D&A represents a real economic cost of asset utilization. Rising interest rates significantly compress interest coverage ratios for companies with floating-rate debt. A business with $20M EBITDA, $150M of floating-rate debt at SOFR+400 bps saw its interest expense rise by approximately $3M as SOFR increased from 0% to 5% in 2022-2023, compressing EBITDA interest coverage from 4.0x to roughly 2.5x with no change in operating performance. This dynamic drove widespread covenant amendment activity in PE portfolios during the rate-tightening cycle and underscores the importance of modeling interest coverage at stressed interest rates when structuring leveraged transactions.
FAQs
What is a minimum acceptable interest coverage ratio for a leveraged company?
Covenant minimums in leveraged credit facilities typically require 1.5–2.0x EBITDA/Interest coverage. Breaching below 1.0x means the company cannot pay interest from operations alone—a serious distress indicator. Most PE sponsors underwrite to at least 2.0x coverage at the entry point and stress-test to 1.3–1.5x in downside scenarios to ensure no covenant breach even in adverse conditions.
How does PIK (payment-in-kind) interest affect coverage ratios?
PIK interest is not paid in cash—it accretes to the principal balance. As a result, cash interest coverage ratios exclude PIK interest from the denominator, appearing better than total interest coverage. Lenders and analysts must track total interest coverage (including PIK) separately because PIK creates a growing debt obligation that will eventually require cash repayment or refinancing, and companies that rely heavily on PIK may have inadequate cash interest coverage to refinance at market rates.
