A company can report healthy sales or profits and still struggle to meet payments due in the near term. The acid test ratio, also known as the quick ratio, helps assess this by comparing a company’s more liquid assets with its current liabilities, without relying on inventory.
For investors trying to understand how to calculate acid test ratio, the formula is only the starting point. The real value lies in what the number says about short-term liquidity and how it compares with the company’s past performance and industry peers. A ratio that looks comfortable at first glance may tell a different story once you look at what sits behind it.

What is the acid test ratio?
The acid test ratio meaning is straightforward: it measures a company’s ability to meet its current liabilities using assets that are readily available or can be converted into cash relatively quickly.
It is a stricter measure of liquidity than the current ratio because inventory is excluded. Inventory may form a sizeable part of current assets, but it generally needs to be sold before it becomes cash. The acid test ratio therefore focuses more closely on assets available to meet near-term obligations.
The terms acid test ratio and quick ratio are commonly used for the same liquidity measure.

Acid test ratio formula
The basic acid test ratio formula is:
Acid Test Ratio = Quick Assets / Current Liabilities
ICAI’s ratio-analysis material expresses quick assets as:
Quick Assets = Current Assets – Inventories – Prepaid Expenses
This gives the following form of the acid ratio formula:
Acid Test Ratio = (Current Assets – Inventories – Prepaid Expenses) / Current Liabilities
NISM presents a simplified quick-ratio formula as:
Quick Ratio = (Current Assets – Inventory) / Current Liabilities
The difference comes from how quick assets are defined in the calculation. The central idea remains the same: assets that cannot readily be used to meet current liabilities are left out.

What goes into the acid test ratio?
The exact presentation can depend on the financial statements and the definition of quick assets being used. The calculation generally focuses on assets such as:
- Cash and cash equivalents: Funds that are already available in cash or a closely equivalent form.
- Readily marketable investments: Short-term investments that can be converted into cash relatively quickly.
- Receivables: Amounts due from customers or other parties that are expected to be collected.
- Current liabilities: Obligations classified as current on the company’s balance sheet.
Inventory is excluded because it first needs to be sold. Prepaid expenses are also excluded under the ICAI formulation because they represent payments already made rather than assets that can be converted into cash to settle liabilities.

How to calculate acid test ratio
If you are wondering how to calculate acid test ratio, the required figures can usually be found in the company’s balance sheet.
- Identify the company’s quick assets or begin with current assets and remove items such as inventory and prepaid expenses where applicable.
- Find the company’s current liabilities.
- Divide quick assets by current liabilities.
- Compare the result with the company’s previous ratios and relevant peers rather than reading it in isolation.
The acid test ratio calculation itself is relatively straightforward. The more useful analysis begins after the number has been calculated.

Acid test ratio example
Consider a company with the following figures:
| Particular | Amount |
| Cash and cash equivalents | ₹50,000 |
| Readily marketable investments | ₹30,000 |
| Accounts receivable | ₹20,000 |
| Current liabilities | ₹80,000 |
For this acid test ratio example, the quick assets are:
₹50,000 + ₹30,000 + ₹20,000 = ₹1,00,000
Applying the formula:
Acid Test Ratio = ₹1,00,000 / ₹80,000 = 1.25
An acid test ratio of 1.25 means the company has ₹1.25 of quick assets included in the calculation for every ₹1 of current liabilities.
It does not, by itself, mean that the company is financially strong or that its shares are attractive. The ratio tells us specifically about short-term liquidity.
Figures are illustrative.
How to interpret the acid test ratio
Acid test ratio interpretation starts with understanding what the number represents.
- Ratio above 1: The quick assets included in the calculation are greater than current liabilities.
- Ratio equal to 1: Quick assets and current liabilities are equal.
- Ratio below 1: Quick assets are lower than current liabilities. This can warrant a closer look at cash flows, receivable collections and the timing of payments.
These are reference points, not automatic judgements on a company’s financial health. ICAI’s material specifically cautions against relying on a single ratio without understanding its components, while NISM highlights the usefulness of comparing financial ratios over time and against peers.
What is a good acid test ratio?
ICAI’s ratio-analysis material notes that an acid test ratio of 1:1 can be satisfactory. At this level, the value of quick assets is equal to the company’s current liabilities.
However, there is no universal ideal acid test ratio that applies to every company. A ratio should be assessed in the context of the company’s industry, business model, working-capital cycle and past financial position.
A higher ratio should not automatically be interpreted as evidence of a better business either. The acid test ratio measures short-term liquidity, not profitability, operational efficiency, long-term solvency or valuation.

Difference between current ratio and acid test ratio
Both ratios assess short-term liquidity, but they use different measures of current assets.
| Factor | Current ratio | Acid test ratio |
| Formula | Current assets / current liabilities | Quick assets / current liabilities |
| Inventory | Included | Excluded |
| Prepaid expenses | Included within current assets | Excluded under the ICAI quick-assets formulation |
| What it measures | Broader view of short-term liquidity | More conservative test of short-term liquidity |
The difference between current ratio and acid test ratio becomes particularly relevant for businesses that carry substantial inventory. A company may have a relatively high current ratio while recording a much lower quick ratio if inventory makes up a large proportion of its current assets.

Why does the acid test ratio matter to investors?
The acid test ratio can help an investor understand one part of a company’s financial position: its ability to meet short-term obligations using relatively liquid assets.
It becomes more useful when viewed as a trend. If the ratio changes materially from one period to another, an investor can examine what has changed in cash, receivables or current liabilities. Comparing the company with relevant peers can provide further context.
The ratio should still be considered alongside other information such as cash flows, profitability, debt, working-capital trends, business quality and valuation.

How Bajaj AMC looks beyond a single financial ratio
The acid test ratio can indicate a company’s short-term liquidity, but investment analysis usually looks at several factors together.
Bajaj AMC’s INQUBE investment approach considers areas such as business fundamentals, management quality and valuation. For the Bajaj Finserv Small Cap Fund, the investment process also considers factors such as industry structure, financial strength, sensitivity to economic conditions and key earnings drivers.
This broader view helps put liquidity ratios in context. Two companies may have the same acid test ratio but differ significantly in cash flows, management quality or earnings strength.

Limitations of the acid test ratio
The acid test ratio provides a snapshot of short-term liquidity, but it has several limitations.
- It reflects a particular point in time: Balance-sheet figures can change after the reporting date, so one ratio may not show how liquidity behaves throughout the year.
- Receivables are not the same as cash: Amounts due from customers may be included among quick assets, but the time taken to collect them and the likelihood of collection can differ.
- Industry and business models differ: Companies can have very different working-capital requirements, so comparing unrelated businesses using the same threshold may produce a misleading picture.
- Accounting and seasonal factors can affect ratios: Differences in accounting policies, reporting periods and seasonal conditions can influence comparisons between companies or periods.
- It measures only one part of financial health: The ratio does not tell you whether a business is profitable, appropriately valued or financially sound over the long term.
For these reasons, financial ratios are more useful when read together rather than treated as independent measures.

Conclusion
The acid test ratio, or quick ratio, helps assess whether a company has sufficient quick assets relative to its current liabilities without relying on inventory. The formula is easy to calculate, but its usefulness comes from interpreting the result in context.
Rather than treating any single figure as automatically good or bad, compare the ratio with the company’s past numbers, relevant peers and other financial indicators.
FAQs
What is an acid test ratio in accounting?
The acid test ratio is a liquidity ratio that compares a company’s quick assets with its current liabilities. It provides a more conservative measure of short-term liquidity than the current ratio because inventory is excluded.
Is the acid test ratio the same as the quick ratio?
Yes. Acid test ratio and quick ratio are commonly used for the same liquidity measure.
How do you calculate the acid test ratio?
The basic formula is:
Acid Test Ratio = Quick Assets / Current Liabilities
Under the ICAI formulation, quick assets are calculated by subtracting inventories and prepaid expenses from current assets.
Is an acid test ratio of 1.5 good?
An acid test ratio of 1.5 means the company has ₹1.50 of quick assets for every ₹1 of current liabilities included in the calculation. It may indicate a liquidity cushion, but whether the ratio is favourable depends on the company’s business, industry and financial position.
What is a good acid test ratio?
ICAI notes that a ratio of 1:1 can be satisfactory, meaning quick assets equal current liabilities. However, there is no universal benchmark that should be applied to every business.
What does the acid ratio indicate?
The acid ratio indicates how a company’s quick assets compare with its current liabilities. It provides a stricter view of short-term liquidity than the current ratio because it does not rely on inventory.
Why is inventory excluded from the acid test ratio?
Inventory needs to be sold before it can generate cash. Excluding it therefore focuses the ratio on assets that are more readily available to meet current liabilities.
Can the acid test ratio be negative?
Under the conventional formula, the ratio compares quick assets with current liabilities and would ordinarily be zero or positive. If a negative result appears, the underlying figures and their classification should be checked before interpreting it.
Can the acid test ratio be used alone to evaluate a company?
No. It measures short-term liquidity only. Other factors such as cash flows, profitability, debt, business quality, valuation and industry conditions can help provide a broader view.
