Debt-to-EBITDA
Debt-to-EBITDA states leverage in years: how many years of pre-interest, pre-tax, pre-depreciation earnings it would take to pay off the debt load. Lenders live on this ratio — most credit agreements carry a covenant that trips if it crosses a set line, commonly somewhere in the 3.0-4.5x range.
The version that matters is usually net: total debt minus cash, divided by trailing EBITDA. Rough map for non-financial companies: under 1x is a fortress, 2-3x is normal for stable cash generators, above 4-5x is private-equity territory where a mild recession forces hard choices. Rating agencies key large parts of the investment-grade boundary off this number.
Its weakness is inherited from EBITDA itself: depreciation is ignored, so a trucking company at 3x is far more stretched than a software company at 3x — the trucker must keep spending real cash on trucks before any debt gets repaid.
A company carries $1.2B of total debt and $300M of cash, with trailing EBITDA of $500M. Net debt = 1,200 - 300 = $900M, so net debt-to-EBITDA = 900 / 500 = 1.8x. If a downturn cut EBITDA to $250M, the same balance sheet would sit at 3.6x — potentially through its covenant without borrowing another dollar.
