Break-even & cash
Cash Runway Calculator
If nothing changes, when do I run out of cash?
Profit and cash are different questions. This one is cash: what you have, what comes in, what goes out, and how long that lasts.

The answer
Cash runway
10.9 weeks
losing $3,500 per week
- Weekly shortfall$3,500.00
- Weekly sales needed to stop the bleed$34,500
- Extra sales needed per week$3,500.00
- Or weekly costs must fall to$31,000
- Days of runway76 days
- Cash available today$38,000
This assumes nothing changes. Payroll dates, rent timing, and tax deadlines are lumpy, so the real crunch usually arrives before the arithmetic says it will.

Net weekly cash = weekly sales − weekly cash out
When negative, runway in weeks = cash available ÷ weekly shortfall
04 What the answer leaves out
- This is a straight-line model. It does not know about a quarterly tax payment, a seasonal dip, or a supplier tightening terms.
- Set aside sales tax and payroll tax as cash out even though you have collected it. It is not yours to spend.
