This cash flow calculator shows how your cash balance moves month by month. Enter your opening cash, then for each month the money you expect to come in and go out. It works out net cash for each month, the running balance, total inflows and outflows, and warns you about the lowest point so you can plan ahead.

What is a Cash Flow Calculator?
Cash flow is the movement of money into and out of a business or household. Profit and cash are different: a business can be profitable on paper but run out of cash if customers pay late or big bills fall due in the same month.
A cash flow forecast lists expected cash in and cash out for each month and tracks the running balance. This cash flow calculator makes that quick: enter your opening balance and monthly figures, and it highlights the lowest point so you can act before it arrives.
How does the Cash Flow Calculator work?
For each month, the calculator subtracts cash out from cash in to get the net flow, adds it to the running balance and records the lowest balance and when it happens.
How to use the Cash Flow Calculator step by step
- Enter your opening cash balance.
- For each month, enter a name, cash in and cash out.
- Use Add month for more months.
- Read the closing balance and the lowest point.
- Check the monthly table.
- Download the CSV to share with your accountant or bank.

| Status | Balance stays positive |
The cash flow calculator shows the balance dipping to ₹1,00,000 (Dec) before recovering to ₹4,70,000 by March. Knowing the low point in advance lets you arrange a short overdraft or chase receivables early.
