How the acid test ratio is calculated

The acid test ratio, also called the quick ratio, compares liquid assets to current liabilities. Inventory and prepaid expenses are excluded.

  1. Quick assets

    Quick assets=Cash+Marketable securities+Accounts receivable\text{Quick assets} = \text{Cash} + \text{Marketable securities} + \text{Accounts receivable}

    Cash of $50,000.00, marketable securities of $10,000.00, and accounts receivable of $35,000.00 total $95,000.00 in quick assets.

  2. Acid test ratio

    Acid test ratio=Quick assetsCurrent liabilities\text{Acid test ratio} = \frac{\text{Quick assets}}{\text{Current liabilities}}

    Dividing quick assets of $95,000.00 by current liabilities of $60,000.00 gives an acid test ratio of 1.58.

A ratio of 1.0 or higher generally means quick assets can cover current liabilities. Industry norms vary, and receivables may not convert to cash as quickly as the formula assumes. Use the same balance sheet date for every line item.

What is the acid test ratio?

The acid test ratio, also called the quick ratio, measures whether a company can pay its short-term debts with its most liquid assets. It is stricter than the current ratio because inventory and prepaid expenses are left out. Analysts, lenders, and business owners use it as a quick liquidity screen. All math runs in your browser.

Liquidity ratios sit alongside profitability analysis. After you know net income from the accounting profit calculator, the accrual ratio calculator checks how much of those earnings are backed by cash rather than accounting adjustments. To evaluate whether tight liquidity threatens broader enterprise solvency, check the multi-year bankruptcy risk with the Altman Z-Score calculator. If the business is expanding assets faster than internal funding, the additional funds needed calculator estimates how much new debt or equity is required.

Acid test ratio formula

Quick assets are cash, marketable securities, and accounts receivable. Current liabilities include accounts payable, accrued expenses, wages payable, taxes payable, and short-term debt due within one year.

Acid test ratio=Cash+Marketable securities+Accounts receivableCurrent liabilities\text{Acid test ratio} = \frac{\text{Cash} + \text{Marketable securities} + \text{Accounts receivable}}{\text{Current liabilities}}

Some analysts compute the same ratio by subtracting inventory and prepaid expenses from total current assets. Both methods answer the same question when the balance sheet is consistent.

Acid test ratio=Current assetsInventoryPrepaid expensesCurrent liabilities\text{Acid test ratio} = \frac{\text{Current assets} - \text{Inventory} - \text{Prepaid expenses}}{\text{Current liabilities}}

Worked example

Suppose a business reports $31,500 in cash and cash equivalents, $15,700 in marketable securities, $10,300 in accounts receivable, and $44,100 in current liabilities. Quick assets total $57,500. Dividing by current liabilities gives an acid test ratio of about 1.30, meaning liquid assets cover short-term obligations 1.3 times over.

$31,500+$15,700+$10,300$44,100=1.30\frac{\$31{,}500 + \$15{,}700 + \$10{,}300}{\$44{,}100} = 1.30

How to interpret the result

A ratio of 1.0 or higher usually signals that quick assets can meet near-term obligations without selling inventory. Ratios well above 1.0 can mean strong liquidity, but they may also mean cash is sitting idle instead of being reinvested. Ratios below 1.0 suggest the company may need inventory sales, new financing, or faster collections to pay bills on time.

Context matters. A retailer with fast inventory turnover may run a lower quick ratio than a software firm with little inventory. Seasonal businesses should compare the same point in the cycle year over year. Stale receivables over 90 days may not convert to cash quickly, so some analysts trim doubtful accounts before calculating the ratio.

Acid test ratio vs current ratio

The current ratio divides all current assets by current liabilities. Because inventory and prepaid items are included, the current ratio is usually higher and less conservative. The acid test ratio focuses only on assets that can be turned into cash quickly, which makes it a better stress test when collections slow or inventory is hard to sell.

Frequently asked questions

What is a good acid test ratio?
Many analysts treat 1.0 as a baseline: quick assets at least equal current liabilities. Ratios between 1.0 and 2.0 are common for healthy businesses. Higher is not always better if excess cash could earn a return elsewhere. Compare your result to industry peers and your own history.
Why is inventory excluded?
Inventory can take weeks or months to sell and may need to be discounted in a rush. The acid test ratio assumes you need to pay creditors soon, so only assets that convert to cash quickly count in the numerator.
Are cash equivalents the same as cash?
Cash equivalents are short-term, highly liquid investments that mature within three months, such as Treasury bills or money market funds. This calculator combines them with cash in one field. Add both balances before entering the amount.
What counts as marketable securities?
Marketable securities are stocks, bonds, and other investments that can be sold quickly in an active market with little price impact. They are separate from long-term investments that a company intends to hold for years.
Can the ratio be too high?
Yes. A very high ratio may mean the company is hoarding cash instead of investing in growth, paying down expensive debt, or returning capital to owners. Liquidity is important, but idle cash has an opportunity cost.
Does this calculator store my data?
No. Every calculation runs locally in your browser. Changing inputs updates the page URL so you can bookmark or share a scenario, but nothing is sent to a server.
