How to use this calculator

Enter opening cash, service revenue, accounts receivable percentage, and cash outflows. The calculator estimates collected cash, net cash flow, and ending cash.

Use it to detect cash problems even when reported revenue looks healthy.

What the result means

Service businesses can be profitable but cash-poor when customers pay late. Ending cash and cash gap show whether collections support operations.

Collected cash = revenue × (1 − receivable rate). Net cash flow = collected cash − cash outflows. Ending cash = opening cash + net cash flow.

Accounts receivable is not usable cash until collected. High receivables can create payroll or supplier payment pressure.

Example calculation

If opening cash is $20,000, revenue is $30,000, receivables are 20%, and outflows are $24,000, collected cash is $24,000 and ending cash remains $20,000.

Tips for better results

  • Shorten payment terms for new clients.
  • Collect deposits before delivery.
  • Keep cash reserves for payroll and contractor payments.

FAQ

How do I improve cash collection?

Use deposits, shorter payment terms, automated invoices, late payment reminders, and milestone billing.
