Acid Test Ratio or Quick Ratio
The Ratio of current liabilities to current assets excluding stocks is called acid test ratio. Also known as quick ratio or liquid ratio measures the ability of a company to use its near cash or quick assets to immediately extinguish or retire its current liabilities. Quick assets include those current assets that presumably can be quickly converted to cash at close to their book values.
Quick (Acid Test) Ratio= Cash + Markatable Securities + Accounts Receivables / Current Liabilities
Acid test ratio near to 1:1 is considered better for the company .
