Cash Runway Calculator

Move the sliders and see the answer change: how many months of cash your business has left at the current burn rate, and whether your revenue growth gets you to cash-positive before it runs out.

Adjust the sliders — your runway updates instantly.

Your numbers

Cash-positive by month

9

At this growth rate, monthly revenue overtakes monthly costs around month 9 — cash on hand is projected to keep building rather than run out.

Current monthly net burn $4,000
Projected balance in 12 months $28,310
Revenue growth assumption 4%/month

Estimates based on the assumptions above — real offers will differ.

How to Read Your Result

Four things worth understanding before you plan your next few months.

Runway is a clock, not a verdict It tells you how long you have to act at current trends — not that the business is failing. Short runway is a prompt to decide, not a diagnosis.
Growth can outrun the runway entirely If revenue growth is strong enough, monthly income overtakes monthly costs before cash runs out — the tool shows that as a cash-positive result, not an error.
Costs are held flat here This projection grows revenue at your assumed rate and holds costs steady. If you expect costs to rise too, treat the runway as an upper bound.
Small growth-rate changes compound fast Because growth applies every month, a couple of points either way can move the runway by months, not weeks — worth testing both directions.

What This Tool Does and Doesn't Do

The maths is a straightforward month-by-month cash projection, and it runs entirely in your browser. Nothing you type is sent anywhere unless you press "Explain my numbers", and even then only the figures go, never your name or contact details.

What it can't do is account for lumpy cash flow — a big invoice paid late, a seasonal spike, a one-time expense. It assumes smooth, compounding revenue growth and flat costs. Treat the result as a directional read, and revisit it as real numbers come in.

Important: This is educational information, not financial advice. Confirm the figures with a qualified adviser before you commit to anything.
