Accounting Working Capital (Monthly) Calculator
Calculate monthly working capital, liquidity ratios, and the change from the previous month using your current asset and liability balances.
Overview
Use this monthly working capital calculator to compare your short-term assets with your short-term obligations at month-end. Enter cash, receivables, inventory, other current assets, payables, and other current liabilities to estimate net working capital and key liquidity ratios.
How it works
The calculator adds cash, accounts receivable, inventory, and other current assets to find total current assets. It then adds accounts payable and other current liabilities. Net working capital equals current assets minus current liabilities. The current ratio divides all current assets by current liabilities, while the quick ratio uses only cash and receivables. The monthly change compares this month's net working capital with the figure entered for the prior month.

Frequently asked questions
What is monthly working capital?
Monthly working capital is the difference between current assets and current liabilities measured at a particular month-end. It helps show the funds available for normal short-term operations.
How is net working capital calculated?
Net working capital equals total current assets minus total current liabilities. A positive result means current assets exceed current liabilities at the reporting date.
What is a current ratio?
The current ratio is total current assets divided by total current liabilities. It shows the amount of short-term assets available for each unit of short-term obligations.
What is the difference between the current ratio and quick ratio?
The current ratio includes all current assets. The quick ratio focuses on cash and accounts receivable, excluding inventory and other assets that may take longer to convert into cash.
Can working capital be negative?
Yes. Negative working capital occurs when current liabilities are greater than current assets. Whether this is a concern depends on cash timing, industry practices, financing arrangements, and the business model.
Why compare working capital month by month?
Monthly comparisons can reveal changes in collections, inventory levels, supplier payment timing, and short-term funding needs that may not be clear from a single month-end balance.

- A positive working capital balance does not by itself guarantee that all obligations can be paid when due.
- Review overdue receivables, restricted cash, debt terms, and unusual liabilities separately when assessing liquidity.
