When Debt Helps and When It Kills

intermediate7 min read

Leverage amplifies both ways. The difference between borrowing to grow and borrowing to survive.

Debt is a tool, not a sin. The same loan can be brilliant or fatal depending on what it funds and whether the business can service it. The key distinction:

Good debt — borrowed cheaply to fund projects that earn MORE than the interest cost, expanding a proven, profitable business. It amplifies returns to owners.
Bad debt — borrowed to plug losses, fund vanity acquisitions, or simply survive. It amplifies the path to ruin.

Leverage is a magnifying glass: it makes a good business better and a bad business deadly. In good times debt flatters returns and everyone looks smart; it’s the downturn that separates prudent borrowers from reckless ones. Most spectacular corporate collapses share one ingredient — too much debt meeting a bad year.

Practical lens: is debt funding growth that out-earns its cost (good), and can the company comfortably cover interest even in a downturn (safe)? If yes to both, leverage is working for owners. If debt is rising while profits aren’t, run.

Key takeawayDebt that funds high-return growth and is easily serviced amplifies owner returns; debt that funds losses or can’t be comfortably covered amplifies ruin. Leverage magnifies both directions.

FAQs

Should I avoid all indebted companies?

No — sensible debt is normal and can boost returns. Avoid companies whose debt is high AND rising AND poorly covered by profits, or whose debt funds losses rather than productive growth. Context (industry, coverage, what the debt funds) is everything.
