How Cash Flow Forecasting Works

A cash flow forecast projects your business's future cash position by mapping out expected income and expenses month by month. It answers the most critical question for any business: will I have enough cash to keep operating?

Runway is how many months your business can survive before cash runs out. If your monthly expenses exceed revenue, runway tells you exactly when you'll hit zero — giving you time to cut costs, raise prices, or find additional funding.

Break-even month is when your cumulative cash inflows finally exceed cumulative outflows. After this point, the business has generated more cash than it has consumed since the start of the projection.

The growth rate compounds monthly on your base revenue. Even modest growth (3-5% monthly) can dramatically change your cash picture over 12-24 months. But be conservative — overestimating growth is the most common mistake in cash flow planning.
