Quick Ratio (Acid Test)

Ratio of liquid assets (excluding inventory) to current liabilities, a stricter measure of short-term liquidity

What is Quick Ratio (Acid Test)?

Quick ratio, also called the acid test, compares a business's most liquid current assets with its current liabilities. It excludes inventory, which may be slow to convert into cash.

It is a stricter test of short-term financial health than the current ratio.

How to calculate it

Subtract inventory from current assets, and divide the result by current liabilities.

For example, with current assets of 3,000,000, inventory of 1,000,000 and current liabilities of 2,000,000, the quick ratio is (3,000,000 - 1,000,000) / 2,000,000 = 1.0.

A ratio of at least 1 suggests the business can meet short-term obligations without selling stock. Interpret with the industry in mind.

Where it is used

  • Testing liquidity strictly

    See the ability to pay without selling stock.

  • Lender assessments

    Support credit decisions.

  • Monitoring trends

    Watch for weakening liquidity.
