Cash Flow Forecast Example for a UK Limited Company

This fictional example shows why an invoice is not the same as money in the bank. Start with payment dates and use the forecast to spot a shortage before it arrives.

A three-month worked example

Northway Services Ltd starts with £6,000. The figures below are cash movements, not a profit-and-loss statement. They exclude VAT, payroll and tax solely to keep the arithmetic easy to follow. Add those items to a real forecast where they apply.

Illustrative cash forecast (£)
Cash movementMonth 1Month 2Month 3
Opening balance6,0004,0003,500
Customer receipts4,0006,0008,000
Operating payments5,0005,0005,500
Equipment payments1,0001,5000
Closing balance4,0003,5006,000

Check the arithmetic

Month 2 closes at £3,500: £4,000 opening cash plus £6,000 received, less £5,000 operating costs and £1,500 equipment. That becomes Month 3’s opening cash. Every month must join up this way.

Now test a late payment

If £3,000 expected in Month 2 arrives in Month 3 instead, Month 2 closes at £500. Month 3 still closes at £6,000 if everything else stays unchanged. The eventual total hides a period when the business has very little room for another bill.

That is why a forecast should show a minimum cash buffer and realistic collection dates. An apparently healthy sales month may still create a short-term payment problem.

Make the example fit your company

Replace the totals with customer-by-customer receipts and dated bills. Add VAT payments, payroll, tax, borrowing, director funding and dividends only where appropriate and supported. The bank balance is not automatically available for distribution.
