What is the cash flow calculator — operating, investing & financing?

In short

Net cash flow = operating + investing + financing cash flow. Example: $50,000 operating inflow minus $35,000 in operating costs nets +$15,000; a $10,000 equipment purchase gives −$10,000 investing; a $5,000 loan minus $2,000 repayment nets +$3,000 financing — for a total net cash flow of +$8,000 for the period.

Calculates operating, investing, and financing cash flows and net cash position from your business's inflows and outflows in each category.

How to use this calculator

  1. 1Enter operating inflows (sales receipts, collections).
  2. 2Enter operating outflows (payroll, rent, COGS payments).
  3. 3Enter investing inflows (asset sales, investments sold).
  4. 4Enter investing outflows (equipment purchases, capital expenditures).
  5. 5Enter financing inflows (loans received, equity raised).
  6. 6Enter financing outflows (loan repayments, dividends paid).

The formula

OCF=op. inflows−op. outflows
Net CF=OCF+ICF+FCF
OCF = Operating Inflows − Operating Outflows; ICF = Investing Inflows − Investing Outflows; FCF = Financing Inflows − Financing Outflows; Net = OCF + ICF + FCF
OCF
— Operating cash flow
ICF
— Investing cash flow
FCF
— Financing cash flow

Worked example

The scenario

Operating: $50K in, $35K out. Investing: $0 in, $10K out. Financing: $5K in (loan), $2K out (repayment).

gives

The result

OCF: +$15,000. ICF: −$10,000. FCF: +$3,000. Net cash flow: +$8,000.

Common use cases

  • Analyze quarterly or annual cash flow statement.
  • Identify cash flow problems even when profit looks fine.
  • Present cash position to investors or lenders.
  • Model the impact of a capital expenditure on cash.

Limitations & assumptions

  • This is a simplified model — a formal cash flow statement under GAAP has many adjustments from net income (depreciation, working capital changes).
  • Indirect method (starting from net income) is most common; this uses the direct method.
  • Operating lease payments now appear in financing under ASC 842.
  • Does not handle foreign currency translation or intercompany transactions.

Frequently asked questions

Profit is accrual-based (revenue when earned, expenses when incurred). Cash flow is actual money in/out — a business can book $50,000 of profit while $80,000 sits uncollected in receivables. High receivables, heavy inventory, or rapid growth can leave a profitable business cash-poor, and many business failures happen to profitable but cash-flow-negative companies.
