What is Acid Test Ratio?

The acid test ratio is a measure of a company’s short-term liquidity, indicating its capacity to pay off current commitments using just its most liquid assets. It is calculated by dividing the sum of cash, cash equivalents, marketable securities or short-term investments, and current accounts receivables by the total current liabilities.

The understanding of the acid test ratio is very important as it shows the company’s potential to convert its assets into cash very quickly in order to satisfy its current liabilities. If an entity has an adequate level of liquid assets to cover its current liabilities, then it doesn’t need to liquidate any of its long-term assets to meet its current obligations. This point is of paramount importance since most businesses rely on long-term assets to generate additional revenue.
