CashRunway 13

See the week your cash runs short — 13 weeks before it happens.

CashRunway 13 is an Excel workbook that builds a 13-week rolling cash flow forecast from two simple lists: recurring items (payroll every two weeks, rent on the 1st, quarterly taxes) and dated one-off items (expected invoice payments, purchases). It flags low-cash weeks, runs scenarios, tracks actuals against forecast and prints a one-page lender summary.

FAQ

Do I need to type numbers into 13 columns?

No. You enter each recurring item once with its frequency and start date, and list one-off items with their dates. The workbook places them in the right weeks.

How do I roll the forecast forward?

Move the start date on by 7 days and enter your current bank balance. Recurring items reschedule automatically.

Does it contain macros?

No — only standard Excel formulas, so it opens without security prompts.
