Cash Flow Calculator (12-Month Forecast)

Will you have enough cash every month? Use this free 12-month cash flow calculator to find out, and learn how to improve your cash flow.

In short: cash flow is the money coming into and going out of your business each month. A cash flow forecast shows whether you will have enough cash every month — not just whether you make a profit over the year.

Why Cash Flow Matters

A business can be profitable on paper and still run out of cash — for example, when sales start slowly or big bills come early. A simple monthly forecast helps you see a cash shortage before it happens.

How to Read Your Forecast

  • Cash in is the money from sales that month.
  • Cash out is the cost of what you sell, plus fixed costs and loan repayments.
  • Lowest cash point is the month you are closest to running out. Plan your funding around it.

The starting example uses the illustrative bakery from our other guides. It keeps things simple: no taxes, and sales are paid right away. Adjust it if customers pay you later or you pay taxes monthly.

How to Improve Cash Flow

  • Get paid faster — ask for deposits or payment on delivery.
  • Pay big bills in parts where suppliers allow it.
  • Keep a cash cushion for slow months.
  • Hold less stock so cash is not stuck on shelves.

Where It Fits in Your Business Plan

Cash flow belongs in the Financial Plan and Projections section, next to your startup costs and financial projections.
