Working Capital Ratio Calculator

What it is and when to use it

The working capital ratio, also called the current ratio, compares a company's current assets (cash, receivables, inventory and other items expected to convert to cash within a year) with its current liabilities (bills, short-term debt and other obligations due within a year). It is a quick test of whether a business can cover its near-term obligations from resources it already holds.

Use this calculator to review your own balance sheet, to compare a company with its peers or its own history, or to check a lender's or supplier's view of your liquidity. It also reports working capital in dollars and a quick ratio, which strips out inventory because stock can be slow to turn into cash. It is a snapshot of one date, not a forecast, and it is not financial advice.

The formulas

Working capital ratio = current assets ÷ current liabilitiesWorking capital = current assets − current liabilitiesQuick ratio = (current assets − inventory) ÷ current liabilities

Current assets and liabilities come from the balance sheet, and inventory is optional. The reading line uses a widely quoted rule of thumb: below 1.0 means liabilities exceed current assets, roughly 1.0 to 2.0 is often regarded as comfortable, and above 2.0 can suggest cash or stock that is not being used efficiently. Suitable levels differ a lot between industries.

Worked example: a small distributor

Current assets are $250,000, current liabilities are $160,000 and inventory is $70,000.

Working capital ratio = 250,000 / 160,000 = 1.5625, shown as 1.56. Working capital = 250,000 − 160,000 = $90,000.

Quick ratio = (250,000 − 70,000) / 160,000 = 1.125, displayed as 1.13. The business covers its short-term liabilities 1.56 times overall, but only about 1.13 times if inventory cannot be sold quickly.

Common mistakes and how to interpret the result

Reading the ratio in isolation. A retailer with fast-moving stock can operate safely at a lower ratio than a manufacturer with slow inventory, so compare like with like.
Assuming higher is always better. Very high figures can mean idle cash, uncollected receivables or excess inventory rather than strength.
Ignoring the quality of current assets. Receivables that will not be paid and obsolete stock count in current assets but may never turn into cash.
Using stale numbers. Balance sheet values change with the season and with payment timing, so recalculate with current figures, and consider average values for seasonal businesses.

Frequently Asked Questions

What is a good working capital ratio?

Many analysts treat 1.2 to 2.0 as a healthy range, and below 1.0 as a warning that current liabilities exceed current assets. The right level depends on the industry, business model and how fast assets convert to cash.

What is the difference between working capital and the working capital ratio?

Working capital is a dollar amount (assets minus liabilities). The ratio divides assets by liabilities, so it lets you compare businesses of different sizes.

Why is the quick ratio also shown?

Inventory can be slow to sell or sold at a discount, so the quick ratio removes it and shows how well the most liquid assets cover current liabilities. A large gap between the two ratios means the business relies heavily on inventory.

Can working capital be negative?

Yes. If current liabilities exceed current assets, working capital is negative. It can be normal for businesses that collect cash before paying suppliers, such as some subscription or grocery models, but for many businesses it signals liquidity strain.
