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

Current ratio = Current assetsCurrent liabilities

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

   = £15,545 £5,060=    3.07 : 1

  • 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

Acid test = Current assets  StockCurrent liabilities

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

=£15,545  £8,250=£7,295 

Acid test

=£7,295£5,060 = 1.44 : 1 

  • 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

Method

Explanation

Reduce the credit period offered to customers

  • Collecting money owed from customers more quickly will increase the level of current assets in the business

  • Customers may move to competing businesses that offer better credit terms

Ask suppliers for an extended repayment period, e.g. an extension from 60 to 90 days

  • Current liabilities will not be reduced

  • The business can use the cash it would have paid to suppliers for other purposes

  • Suppliers may be unwilling to extend credit terms

Make use of overdraft facilities or short-term loans

  • Current liabilities will increase

  • The business can spend more money than it has in its bank account

  • Banks may be reluctant to lend to businesses with cash-flow problems

Sell off excess stock

  • Less liquid current assets will be reduced and converted into more liquid forms of current assets (e.g. cash)

  • Storage and security costs may also be reduced

  • Stock may need to be sold at a low price to attract sales

Sell assets and lease fixed assets instead (e.g. sale and leaseback)

  • Both current assets and current liabilities will increase

  • The business will continue to have the use of the assets but must make regular payments to the leasing company

Introduce new capital and reduce drawings from the business

  • New capital may be introduced by the owner or from additional investors

  • This may result in the dilution of control of the business
