Growth has to be paid for before it pays you back. See how much cash your plan will eat, how fast you can grow from your own cash, and how much funding you'll need.

Who this is for

Owners who are planning to grow and want to know whether they can fund it from the business's own cash, or how much they'll need to borrow or raise. It's especially relevant if customers pay on credit terms, or if you hold stock or work in progress.

What it measures

Growth has to be paid for before it pays you back. Extra sales mean more money owed to you by customers and more stock or work in progress, and both have to be funded before the cash comes in. The calculator uses your sales, gross margin, payment terms and the profit you keep in the business to work out three things:

  • how much cash each year of your growth plan will tie up
  • your self-funded speed limit: how fast you can grow from your own cash
  • how much funding you'll need to grow faster than that

It also shows how much tighter payment terms could release before you borrow.

How to read your results

Start with the speed limit. If your plan grows faster than it, the gap has to be funded from somewhere, or the growth will drain your bank balance. Next, look at the "fund it from inside first" levers. Collecting cash a few days faster or holding less stock often closes much of the gap without borrowing. Whatever gap is left is what you take to a lender, and you'll go with a number and a plan rather than a request.

Worked example: Brightwater Fabrications

Brightwater Fabrications is a fictional manufacturer with £4m of sales, a 40% gross margin, 60 debtor days, 45 stock days and 40 creditor days. It keeps £150,000 of profit in the business each year. On those terms, roughly 17p of every extra £1 of sales is tied up in customers and stock. That puts its self-funded speed limit at 22% growth a year. Its plan is to grow 25% a year for three years, from £4m to £7.8m. That's faster than its own cash can carry: it needs about £86,000 of funding at the peak. But every day off its debtor days releases about £11,000, so collecting just three days sooner would cover year one's gap on its own.

Frequently asked questions

Why would a profitable business need funding to grow?
Because the profit arrives after the costs. You pay staff and suppliers to deliver the extra work now, and your customers pay you later. The faster you grow, the bigger that gap becomes.
What figures do I need?
Last year's sales and gross margin, roughly how long customers take to pay you, how much stock you hold and how long you take to pay suppliers, and the profit you keep in the business after tax and dividends.
Can I reduce the funding I need?
Usually, yes. Faster invoicing, deposits, tighter credit control and holding less stock all release cash. The calculator shows how much each would be worth before you approach a lender.
