What is Acid Test Ratio Formula?
The formula for acid test ratio is a measure of liquidity which is calculated by dividing the summation of the most liquid assets like cash, cash equivalents, marketable securities or shortterm investments and current accounts receivables by the total current liabilities. The ratio is also known as a Quick Ratio.
It can be calculated using two methods
Method 1 – Acid Test Ratio Formula
Mathematically it is represented as,
 Step 1: Firstly, all the liquid assets like cash, cash equivalents, shortterm investments or marketable securities and current accounts which can be liquidated within 90 days are identified from the balance sheet and then added up.
 Step 2: Now, the acid test ratio is computed by dividing the summation of the liquid assets in Step 1 by the total current liabilities from the balance sheet.
Method 2 – Acid Test Ratio Formula
Another formula which is more popularly used calculates acid test ratio first by deducting inventory from the total current assets and then diving the value by the total current liabilities. Inventory is excluded in this formula because it is not considered to be rapidly cash convertible. Mathematically it is represented as,
 Step 1: Firstly, identify the sum of all the current assets and the inventory from the balance sheet and then deduct the inventory from the total current assets.
 Step 2: Now, the acid test ratio computed by dividing the value in Step 1 by the total current liabilities from the balance sheet.
As can be seen from above, the acid test ratio formula assesses the liquidity position of an entity by computing how well the most liquid assets can cover the current liabilities.
Examples of Acid Test Ratio Formula
Below are some of the examples to understand Acid Test Ratio in a better manner.
Acid test Ratio Formula Example #1
The following are the current assets and current liabilities of ABC Limited:
Using the abovementioned formula the acid test ratio of ABC Limited can be calculated as:
 Acid test ratio = ($2,500 + $12,500) / ($12,500 + $1,500 + $500)
 Acid test ratio = 1.03
Acid Test Ratio Formula Example #2
The following are the current assets and current liabilities of Apple Inc. for the period ending 29 September 2018:
Using the abovementioned formula the acid test ratio of Apple Inc for the period ending 29 September 2018 can be calculated as:
 Acid test ratio = ($25,913 + $40,388 + $48,995 + $12,087) / ($55,888 + $20,748 + $40,230)
 Acid test ratio = 1.09

Relevance and Uses of Acid Test Ratio Formula
The understanding of the acid test ratio is very important as it shows an entity’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 longterm assets to meet its current obligations. This point is of paramount importance since most businesses rely on longterm assets to generate additional revenue.
 If the acid test ratio of an entity is greater than 1.0, then the entity is considered to be financially secure and sufficiently capable to meet their shortterm liabilities. The acid test ratio is more conservative measure than the popularly used current ratio as it excludes inventory which is considered to take longer to convert into cash.
 As a thumb rule, a low or decreasing trend witnessed in acid test ratio usually indicates that an entity may be having weak topline growth, struggling to manage working capital owing to lower creditor period or higher receivable period.
 On the other hand, a high or increasing trend in acid test ratio generally means that the entity is having strong topline growth, quickly able to convert receivables into cash and comfortable in its financial obligation coverage.
