The "Liquid Ratio" is also known as the "Quick Ratio." Both terms are used interchangeably and refer to a financial ratio that measures a company's ability to meet its short-term financial obligations using its most liquid assets. The formula for the quick ratio is:

Quick Ratio = (Cash + Cash Equivalents + Marketable Securities + Accounts Receivable) / Current Liabilities

The quick ratio provides a more conservative measure of a company's liquidity than the current ratio because it excludes inventory from its calculation. This ratio focuses on the assets that can be quickly converted to cash to meet short-term liabilities, making it a useful indicator of a company's short-term financial health.
