How does the Cash Flow Calculator work?

Net cash flow equals cash inflows minus cash outflows. Ending cash equals starting cash plus net cash flow. This is a direct cash-movement model and does not attempt to convert accrual accounting profit into operating cash flow.

For accounting profit after expenses, use the Net Profit Calculator.

Check the records against actual statements rather than relying on an estimate alone. No purchase is required to use this calculator.

Why can cash flow differ from profit?

Cash timing can differ from revenue and expense recognition. Credit sales, accounts receivable, inventory purchases, loan proceeds, debt repayments, depreciation and capital expenditures can make cash movement different from accounting profit.

The Current Ratio Calculator provides another short-term liquidity perspective using current assets and current liabilities.

How should you interpret net cash flow?

Positive net cash flow means inflows exceeded outflows in the period; negative net cash flow means the opposite. Either result needs context. A growing business may intentionally spend cash, while a profitable business can still face a cash shortage if customer collections lag.

Use the Break-Even Calculator for sales-volume planning rather than cash timing.

How can this calculator support cash planning?

Run separate scenarios for different collection dates, expenses or investment plans. For return on a specific investment, use the ROI Calculator. Formal cash-flow statements contain additional classifications and reconciliation details beyond this simple calculator.

Worked example: Cash Flow

Enter the following values in the Cash Flow Calculator and calculate to reproduce this result.

  • Starting cash optional: 25000
  • Cash inflows: 80000
  • Cash outflows: 72000

Example result: $8,000.00. $80,000.00 of cash inflows minus $72,000.00 of cash outflows produces $8,000.00 net cash flow.

Calculation used: net cash flow = cash inflows − cash outflows

How to interpret this example

Cash inflows minus cash outflows measures movement of money during the chosen period. Positive cash flow is not the same as accounting profit: borrowing, asset purchases and unpaid invoices can affect the two measures differently.
