First teaching 2026
First exams 2028
Exam code: 7132
The current ratio
The current ratio is a quick way to measure liquidity that considers all forms of current asset a business holds
It is an especially effective liquidity measure for businesses that hold little inventory
The result indicates how many £s of current assets it has available to cover each £1 of short-term debt
It is expressed as a ratio, or as a number, and is calculated using the formula
Worked Example
Packer Sports Ltd has current assets of £15,545, current liabilities of £5,060 and an inventory figure of £8,250.
Calculate Packer Sports Ltd’s current ratio.
Current ratio
In this example, Packer Sports Ltd has £3.07 of current assets to cover each £1 of short-term debt
The acid test
This is a more precise way to measure liquidity
The least liquid form of current assets (stock) is deducted as it may take some time to sell and receive payment for it
The acid test ratio provides a more realistic measure of the business's ability to meet short-term debts quickly
It is a particularly important measure of liquidity for businesses that hold a large amount of stock
It is expressed as a ratio, or as a number, and is calculated using the formula
Worked Example
Packer Sports Ltd has current assets of £15,545, current liabilities of £5,060 and an inventory figure of £8,250.
Calculate Packer Sports Ltd’s acid test ratio.
Calculate liquid assets
Acid test
In this example, Packer Sports Ltd has £1.44 of its most liquid current assets to cover each £1 of short-term debt.
Comparing the two ratios
The gap between the current ratio and the acid test ratio reveals how dependent a business is on its stock to maintain liquidity
Case Study
Thornbury Electronics
Thornbury Electronics' finance director has gathered the following data from the company's balance sheet.
Current ratio | 1.73 : 1 |
Acid test ratio | 0.91 : 1 |
Explain why Thornbury Electronics may struggle to pay its current liabilities.
Explanation
The large gap between the two ratios —0.82 — tells us that Thornbury holds a significant amount of its current assets in the form of stock
If that stock is slow-moving or difficult to sell quickly, the business's true liquidity position is weaker than the current ratio alone suggests
With only £0.91 to pay each £1 of debt, the business may struggle to cover its current liabilities
Examiner Tips and Tricks
When interpreting liquidity ratios, always consider the type of business and the time of year. A ratio below the benchmark is not automatically a crisis - a seasonal business may routinely dip below 1:1 at certain points in the year. Equally, a ratio well above 2:1 is not always ideal - it may indicate idle cash that could be invested more productively. Context is everything
How to improve liquidity ratios
The best way to improve liquidity is to manage the business better
Use cash flow forecasts to identify potential cash flow issues before they arise — and take appropriate action
Budget effectively and consider adopting zero budgeting to carefully control spending
Set clear financial objectives and look for ways to reduce costs and increase income wherever possible
