The concept of liquidity

The concept of liquidity

  • Liquidity refers to the cash and other current assets businesses have available to quickly pay bills and meet short-term financial obligations

  • A business that cannot pay its debts is considered insolvent

    • If a business cannot pay its suppliers, raw materials or components may not be delivered, and production may be delayed

    • If it cannot repay an overdraft, banking facilities may be withdrawn, and its credit rating will suffer

    • Creditors may force it to stop trading and sell its assets so that the debts owed to them are repaid

  • The liquidity of a business can be measured using two ratios

    • Current ratio

    • Acid test ratio

Current ratio

Current ratio

  • The current ratio indicates how many £s (or other currency units) of current assets are available to cover each £1 (or other currency unit) of short-term debt

    • Its is a quick way to measure liquidity

      • The outcome is expressed as a ratio

      • All types of current asset are included in calculating this ratio

      • The result

  • It is calculated using the formula

Acid test ratio

Acid test ratio

  • The Acid Test Ratio (also called the Quick Ratio) is a measure of a business’s liquidity – how easily it can pay its short-term debts without relying on selling inventory (stock)

    • It is expressed as a ratio

    • It is also known as the liquid capital ratio

    • The least liquid form of current assets (inventory) is deducted so the acid test ratio provides a more realistic measure of the business'sability to meet short-term debts quickly

      • It often takes time to sell inventory so it is excluded

  • The acid test is calculated using the formula

Acid test ratio =  Current assets - InventoryCurrent liabilities=     ?      :     1{"fontFamily":"Times New Roman","fontSize":"18","autoformat":true,"toolbar":""}
