How to calculate cash flow

To use our cash flow calculator, you would input the following information:

  1. Income: Include all sources of income, such as sales revenue, rental income, interest earned, etc.

  2. Expenses: List all expenses, including operating expenses (such as rent, utilities, salaries), taxes, loan payments, etc.

  3. Investments: If applicable, include any investments or capital expenditures made during the period.

  4. Loans and Financing: Enter any loan payments or financing activities, including both principal and interest payments.

Once you’ve entered this information, the cash flow calculator will calculate the net cash flow for the period, showing whether there’s a surplus or deficit of cash. This can help businesses and individuals plan for future expenses, manage liquidity, and make informed financial decisions.
