Cash flow is the net amount of cash moving into and out of a business or personal account during a period. Positive cash flow means more cash coming in than going out; negative cash flow means the opposite. Cash flow is distinct from profit — a profitable business can still fail if it runs out of cash.

💡

Tip: Build a 13-week cash flow forecast — look ahead 3 months in weekly buckets. This gives enough warning to arrange credit or cut costs before a cash crisis hits.

  1. 1List all cash inflows: revenue received, loans drawn, asset sales, investment proceeds
  2. 2List all cash outflows: expenses paid, loan repayments, capital expenditure, tax
  3. 3Net cash flow = Total inflows − Total outflows
  4. 4For personal finance: income − all expenses including savings contributions

Fun Fact

"Revenue is vanity, profit is sanity, cash is king" is a famous business maxim. More businesses fail due to cash flow problems than from lack of profitability.
