Quick ratio in plain English

The current ratio counts everything the business expects to turn into cash within a year. The quick ratio is tougher: it ignores inventory, because selling stock takes time and may mean discounting it. It asks, “Could we pay our bills quickly if we had to?”

Worked example

Current assets are 60,000, including inventory of 20,000. Current liabilities are 40,000.

Quick ratio = (60,000 − 20,000) ÷ 40,000 = 1.0. The business has 1.00 of quick assets for every 1.00 owed in the short term.

Common mistakes
  • Forgetting to deduct inventory. Some versions also exclude prepaid expenses, so check your syllabus.
  • Treating one ratio as proof of health. Compare with similar businesses and past results.

Frequently asked questions

What is a good quick ratio?

A ratio of around 1 or above is often seen as comfortable, but it varies by industry.

Why is inventory excluded?

Inventory is the least liquid current asset. It may be slow to sell or sell below cost.

What is the difference between the quick ratio and the current ratio?

The current ratio uses all current assets. The quick ratio excludes inventory, so it is a stricter test.
