Cash flow in plain English

A business can show a profit and still run out of cash, for example if customers are slow to pay. Cash flow tracks the actual money moving in and out, which is why lenders and managers watch it closely.

Worked example

ActivityCash flow
Operating: cash from customers less cash paid for costs+30,000
Investing: bought equipment−12,000
Financing: new bank loan+5,000
Net increase in cash+23,000

If cash at the start was 10,000, cash at the end is 10,000 + 23,000 = 33,000.

Common mistakes
  • Assuming profit equals cash flow.
  • Putting a loan receipt in operating activities. Borrowing is a financing activity.
