What is the difference between simple and projected runway?

Simple runway divides cash by the current net burn and assumes nothing changes. Projected runway simulates every month with your growth rates for revenue and costs, so it can show a break-even point or an earlier zero-cash date.

What runway should I have before raising?

A common target is 12 to 18 months of runway when you start a raise, because fund raising itself takes 3 to 6 months. Use the simulation to pick the month when your balance crosses that comfort line.

Are my company's financial numbers uploaded anywhere?

No. The simulation runs entirely in your browser. Your cash, revenue, and cost figures never leave your device.

Can the model show profitability instead of running out of cash?

Yes. If revenue crosses costs before the balance empties, the tool marks the break-even month and reports the company as profitable rather than showing a zero-cash date.

What problem does this solve?

Founders know their bank balance but not the date it runs out, because revenue and costs both move each month. A simple cash-divided-by-burn number hides the trend. This tool simulates month by month with growth rates for both revenue and costs, and flags the break-even and zero-cash months.

Built for: Early-stage founders planning their next fundraise and operators deciding when to cut costs. Finance leads at seed-stage startups get the most direct value.

Worked example

Enter cash on hand of 600,000, monthly revenue of 50,000, and monthly costs of 120,000.
Set revenue growth to 10 percent per month and cost growth to 3 percent per month, a typical early shape.
The tool projects the balance month by month and shows a simple runway near 8 months.
With 10 percent revenue growth, it also shows a projected break-even month before cash hits zero.
Slow the growth rate to 5 percent and see the projected runway shorten, then decide what to change.
