Read Cash Runway Month by Month on One Strip — Free
Paste monthly cash in and out, and read the month the balance turns — with the burn printed on every segment of the strip.
The proof surface
Annualised burn hides the month that matters. The strip shows the crossing month with the arithmetic on every segment, which is what a lender or a co-director needs to see.
Why the flat version breaks
Averaging the burn
An average monthly burn of $8,000 hides a $15,000 January that includes VAT and insurance, which is the month that actually breaks the plan.
Facility covenants
Overdraft limits and covenants behave like a floor, and a strip drawn against the operating floor looks comfortable right up to the breach.
Counting invoiced as cash
Revenue invoiced in month two often lands in month four, which is why the strip asks for cash in, not sales.
How to work the runway strip
Cash in and out per month, from the bank statement rather than the sales ledger.
The number that decides the turning month: payroll, VAT, or a covenant.
Segments cross the floor rule and turn hot, with the monthly burn printed alongside.
Cut or defer the largest variable cost in the month before the crossing, not in it.
What the strip replaces
| Question | Before | On the strip |
|---|---|---|
| When does cash run out | annualised burn estimate | closing balance per month with the floor rule |
| Which month to act in | the month it looks bad | the month before the floor is crossed |
| What to tell the board | a spreadsheet tab | the strip with the turning month named |
Numbers come from your own figures; the strip is arithmetic, not a forecast, and it does not model new revenue that has not been invoiced.

Data note: Everything runs in this browser tab on the runway strip: your monthly cash figures stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Go deeper: the companion app files the same reading as a paper ticker strip
The article demo above runs without limits. The companion app keeps a local history, exports the rows as CSV, prints the ready-to-mail packet, and holds your drafts on this device — one free run, then $ 12 one-time for the layer that keeps filing.
The strip and the turning month are free. The paid layer keeps the strip across quarters and prints the cash memo for a lender.
Open the runway strip companionBoundary
This runway strip works only on the monthly cash figures you paste you paste. It does not produce statutory accounts, does not forecast revenue you have not invoiced, and does not advise on insolvency. The figures describe what you supplied, not what is true in the world. Confirm anything you plan to act on with your accountant before changing payment terms or drawing on a facility before you rely on it.
What this is built on
- Every figure comes from the monthly cash figures you paste you paste; nothing is looked up, scraped or asserted as verified.
- Method: closing balance = previous balance + in − out, with the floor rule drawn across and the crossing month marked
- Sample values are labelled samples — illustrative by design, not your data and not a quotation of any organisation's policy.
Before: the reader knew things were tight. After: they can see the floor crossed in month four, with the burn rate printed beside it.
