What is debt?

Debt is borrowed capital that the company is contractually obligated to repay — typically with interest — over a defined period. Debt sits on the balance sheet as a liability; interest flows through the income statement; principal and interest payments hit the financing and operating sections of the cash flow statement.

Common forms

  • Bank term loan: fixed schedule, fixed or floating rate, financial covenants.
  • Revolving credit facility: drawable up to a limit, useful for working-capital swings.
  • Bond / note issuance: tradable debt instruments, public or private placement.
  • Convertible note: debt that converts to equity at a triggering event — used heavily by early-stage startups before priced rounds.
  • Venture debt: hybrid loan + warrants extended to venture-backed companies; complements equity rather than replacing it.

Debt vs. equity financing

  • Cost: debt is generally cheaper after tax (interest is deductible) but rigid — fixed payments regardless of revenue.
  • Control: debt does not dilute ownership but typically imposes covenants and board observation rights.
  • Risk: excessive debt amplifies returns in growth and amplifies losses in downturn — the classic financial-leverage trade-off.

Metrics that matter

  • Debt-to-equity: capital-structure leverage.
  • Net debt: total debt minus cash.
  • Debt-to-EBITDA: how many years of operating cash flow needed to repay; lenders cap this in covenants.
  • Interest coverage: EBIT ÷ interest expense; below 2× signals stress.

Do: match the debt’s tenor and amortisation to the cash-flow profile of the asset it funds; build a covenant compliance dashboard.
Don’t: use debt as a substitute for equity in an unproven business model — debt service is the first cost to fail when growth stalls.
