Check cash reserves, expected payments and upcoming expenses to estimate any shortfall. Start with time sheets, engagement scopes and invoice ageing. Each example below uses hypothetical values you can replace.
Which calculator should you use?
| Tool | What it answers | What to check |
|---|---|---|
| Days of Operating Cash | Translate cash on hand into days of average operating payments. | This excludes future receipts and uses historical average payments, so it differs from net-burn runway. |
| Cash Runway | Estimate the time until cash is exhausted under constant net burn. | Profit recognition and payment dates differ. Use cash receipts and payments here, not invoice revenue alone. |
These tools answer different questions and may use different units. Choose the tool that measures what you need; a larger result does not necessarily mean a better outcome.
