Definition

Cash break-even is when cash inflows cover cash outflows (net burn is ~0). It can differ from accounting break-even due to timing.

Example

If monthly inflows are $500k and outflows are $500k, cash break-even is reached.

How to use it

  • Cash break-even focuses on cash timing (collections, payables, prepay), not accounting profit.
  • A company can be accounting-profitable but still cash-negative if working capital is consuming cash.
  • Track cash break-even alongside runway to gauge survival risk.

Common mistakes

  • Confusing cash break-even with profitability in financial statements.
  • Ignoring collections timing (AR) and deferred revenue effects.
  • Treating one-time cash events as sustainable break-even.

Measured as

Measure Cash Break-even with the same date, unit basis, and accounting or policy definitions used in the rest of your model.

Misused when

  • Confusing cash break-even with profitability in financial statements.
  • Ignoring collections timing (AR) and deferred revenue effects.
  • Treating one-time cash events as sustainable break-even.

Operator takeaway

  • Cash break-even focuses on cash timing (collections, payables, prepay), not accounting profit.
  • A company can be accounting-profitable but still cash-negative if working capital is consuming cash.
  • Track cash break-even alongside runway to gauge survival risk.
  • Tie Cash Break-even to the same balance-sheet date, scenario, and decision memo you are using elsewhere in the model.
  • Document which claims, costs, or adjustments your team includes before comparing numbers across forecasts, covenants, or valuation work.

Next decision

  • Quantify the impact with Cash Runway Calculator if you need to turn the definition into an operating assumption.
  • Read Runway and burn: gross vs net burn, working capital, and cash levers if the decision depends on interpretation, policy, or trade-offs beyond the raw formula.
