Formula
(Total Debt − Cash) / EBITDAHow to read this chart
Watch the trend more than the level. Declining ratio = deleveraging, growing financial flexibility. Rising ratio = increasing leverage, which constrains dividends, buybacks, and future investment.
Key caveats
- Sector context is essential: 3× is aggressive for a consumer brand but normal for a regulated utility. Always compare to sector peers.
- Large acquisitions spike the ratio temporarily — check whether the integration plan credibly drives paydown.
