Current Ratio & Acid Test Ratio
Business: Cambridge International GCSE (2027 Exams), topic 5.5.9
Current Ratio
The current ratio measures the current assets against the current liabilities of a business.

Current ratio
- Current ratio = Current assets ÷ Current liabilities

Purpose of current ratio
- This is an indicator of liquidity. It measures whether a business has enough cash (or other current assets) to pay for any debts.
Acid Test Ratio
The acid test ratio is an adjustment of the current ratio. It removes inventories from the equation.

Acid test ratio
- Acid test ratio = (Current assets − inventory) ÷ Current liabilities

Purpose of the acid test ratio
- As the acid test ratio excludes inventories, it is particularly useful for businesses with a large number of stocks in the business' working capital. The inventories are typically the most illiquid element of current assets.
