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.
