A “safe” interest coverage ratio isn’t one number — it depends entirely on how the sector makes its money.
Capital-intensive businesses like utilities and real estate carry heavy debt, but can comfortably run on a lower interest coverage ratio of 1.5x–2.5x. Their revenues, often backed by long-term leases or regulated rates, rarely dry up — so debt service stays manageable even on slim margins.
Cyclical industries like commodities and retail face far more unpredictable swings. A sudden drop in demand or a dip in prices can crush profits fast. To survive those dry spells without defaulting, these companies need a much bigger safety margin — ideally an ICR of 3.5x or higher.
Financial takeaway
Don’t judge interest coverage against a single target number. A healthy ICR depends entirely on how reliable a company’s cash flow is when times get tough.
