Working Capital Calculator: Liquidity and Current Ratio

Working capital is the cash cushion that keeps a business running day to day: current assets minus current liabilities. It tells you whether you can cover the bills due in the next year with the assets you can turn into cash in that same window. The calculator above runs the math instantly and translates the result into a plain read on your liquidity.

How to calculate working capital

The formula is short: working capital equals current assets minus current liabilities. Current assets are cash and anything you expect to convert to cash within twelve months, such as accounts receivable, inventory, and prepaid expenses. Current liabilities are obligations due within twelve months, such as accounts payable, accrued expenses, and the current portion of any loans.

Take a simple example. A business holds $150,000 in current assets and owes $90,000 in current liabilities. Working capital is $150,000 minus $90,000, or $60,000. That $60,000 is the buffer available to fund operations, absorb a slow month, or invest in growth without reaching for new financing.

What is a good working capital ratio?

The working capital ratio is the same idea expressed as a number rather than a dollar amount: current assets divided by current liabilities. It is identical to the current ratio. In the example above, $150,000 divided by $90,000 gives a ratio of about 1.67.

For most businesses, a ratio between 1.5 and 2 is generally healthy. It means you hold $1.50 to $2 of current assets for every $1 of current liabilities, which is enough to cover short-term obligations without leaving cash idle. A ratio below 1 signals you may not be able to pay near-term bills, while a ratio well above 2 can mean capital is sitting unused when it could be funding growth or earning a return elsewhere.

How to improve working capital

Improving working capital usually comes down to three levers. First, collect receivables faster: tighten payment terms, invoice promptly, and follow up on overdue accounts so cash arrives sooner. Second, manage inventory so you are not parking cash in stock that sells slowly; right-size order quantities and clear dead stock. Third, manage payables sensibly by using the full terms your suppliers allow without straining the relationship, which keeps cash in the business a little longer. Done together, these moves widen the gap between what you own short term and what you owe short term, which is exactly what working capital measures.
