Quick ratio

In finance, the Acid-test or quick ratio or liquid ratio measures the ability of a company to use its near cash or quick assets to extinguish or retire its current liabilities immediately. Quick assets include those current assets that presumably can be quickly converted to cash at close to their book values. A company with a quick ratio of less than 1 cannot currently fully pay back its current liabilities. Note that inventory is excluded from the sum of assets in the quick ratio, but included in the current ratio. Ratios are tests of viability for business entities but do not give a complete picture of the business' health. If a business has large amounts in accounts receivable which are due for payment after a long period, and essential business expenses and accounts payable due for immediate payment, the quick ratio may look healthy when the business is actually about to run out of cash. In contrast, if the business has negotiated fast payment or cash from customers, and long terms from suppliers, it may have a very low quick ratio and yet be very healthy. Generally, the acid test ratio should be 1:1 or higher, however this varies widely by industry.
