What are liquidity ratios?

  • Liquidity ratios are ways to measure how quickly a business can convert assets into cash

    • They compare the current assets to the current liabilities

  • The liquidity ratios are:

    • Current ratio

    • Liquid (acid test) ratio

Current ratio

Current ratio

What is the current ratio?

  • The current ratio is also known as the working capital ratio

    • Working capital is current assets minus current liabilities

What is the formula?

Current assetsCurrent liabilities{"fontFamily":"Times New Roman","fontSize":"18","autoformat":true,"toolbar":""}

How should the value be written?

Write as a ratio (X : 1)

How should the value be rounded?

Round to two decimal places

What does the value mean?

The value represents the amount of current assets available to cover each $1 of current liability

How can the ratio be increased?

  • Increase current assets by introducing capital or selling non-current assets

  • Reduce current liabilities, such as overdrafts and trade payables

  • A ratio close to 2:1 is generally good

    • If it is less than 1:1 then the business does not have enough current assets to cover its current liabilities

    • If it is too high then the business could have too much inventory or trade receivables

      • They need to improve their inventory control

      • They need to encourage credit customers to pay faster

Liquid (acid test) ratio

Liquid (acid test) ratio

What is the liquid (acid test) ratio?

  • The liquid ratio is also known as the acid test or the quick ratio

  • It measures how well current liabilities are covered by the more liquid forms of current assets—cash and trade receivables

What is the formula?

Current assets - InventoryCurrent liabilities{"fontFamily":"Times New Roman","fontSize":"18","autoformat":true,"toolbar":""}

How should the value be written?

Write as a ratio (X : 1)

How should the value be rounded?

Round to two decimal places

What does the value mean?

The value represents the amount of cash and receivables available to cover each $1 of current liability

How can the ratio be increased?

  • Increase current assets, especially cash, by introducing capital or selling non-current assets

  • Reduce current liabilities, such as overdrafts and trade payables

  • A ratio close to 1:1 is generally good

    • If it is above 1:1 then the business has enough liquid assets to cover its short-term debts even if the inventory cannot be sold

    • If it is too high then the business could be owed too much by trade receivables

      • They need to encourage credit customers to pay faster

Evaluating liquidity

Evaluating liquidity

How do I evaluate the liquidity of a business?

  • The liquid ratio is the best indicator of the liquidity of a business

  • However, it is helpful to look at both ratios together

  • The difference between the two ratios tells you about the proportion of the current assets that are made up of inventory

    • The current ratio might be good but the liquid ratio might be too low

      • This suggests the business has a lot of money tied up in inventory

    • The ratios might be very similar

      • This suggests the business does not have a lot of inventory

      • This means they might not have sufficient supplies to meet demand

  • If both ratios are too low then:

    • The business might not be able to repay short-term debts on time

    • The business might not have the resources to pay credit suppliers quickly and therefore miss out on cash discounts

    • The owner(s) might not be able to take drawings

  • Pay attention to whether the goods are purchased and sold on credit or cash

    • If goods are purchased using cash then there will be no trade payables

    • If goods are sold for cash then there will be no trade receivables

      • This might not affect the current assets as the bank increases instead of the trade receivables

How do I compare the liquidity of a business between years?

  • Compare the ratios to the same ratios from previous years

  • For each ratio

    • Make a general comment

      • State whether it has improved or gotten worse

      • State the ratios

    • Give possible reasons for the change

  • Possible reasons for a decrease in the ratios

    • Less cash or a higher bank overdraft due to

      • Purchase of a non-current asset

      • Increase in drawings

      • Repayment of long-term loans

    • Decrease in other current assets

      • Trade receivables

    • Increase in current liabilities

      • Trade payables

      • Short-term loans

  • Possible reasons for an increase in the ratios

    • More cash or a lower bank overdraft due to

      • Sale of a non-current asset

      • Decrease in drawings

      • New long-term loans

    • Increase in other current assets

      • Trade receivables

    • Decrease in current liabilities

      • Trade payables

      • Short-term loans
