The quick ratio is cash and cash equivalents plus marketable securities plus net current receivables, divided by total current liabilities, with every figure read off one balance sheet at one date. It measures whether a business could settle its current liabilities out of assets that are already cash or close to it, without selling inventory first. The numerator is called quick assets, and the ratio’s other name is the acid-test ratio.
A ratio of this kind is calculated from information on financial statements rather than presented on them (SEC, Beginners’ Guide to Financial Statements), so no accounting standard fixes its wording and more than one formula travels under the name.
The Formula
Both halves come off the same statement.
quick ratio = (cash and cash equivalents + marketable securities + net current receivables)
/ total current liabilities
Every term in it is a classification question, and classification is what the answer turns on. The term current assets is used to designate cash and other assets or resources commonly identified as those which are reasonably expected to be realized in cash or sold or consumed during the normal operating cycle of the business (ARB No. 43, Chapter 3A, paragraph 4). Quick assets are the part of that group already in cash or one step from it.
What Counts as a Quick Asset
The numerator is assembled from three captions and one contra account rather than lifted off a single line.
Cash is caption 1, cash and cash items, and cash restricted as to withdrawal or usage is disclosed separately (17 CFR 210.5-02). A restriction can push cash out of current assets altogether, because cash and claims to cash restricted as to withdrawal or use for other than current operations, designated for expenditure in the acquisition or construction of noncurrent assets, or segregated for the liquidation of long-term debts are excluded from the classification (ARB No. 43, Chapter 3A, paragraph 6).
Marketable securities is caption 2, and that caption does not itself say which securities qualify, leaving the accounting and disclosure requirements for current marketable equity securities to generally accepted accounting principles (17 CFR 210.5-02). Marketability is not the test. What belongs here is marketable securities representing the investment of cash available for current operations, while investments in securities, whether marketable or not, made for the purposes of control, affiliation, or other continuing business advantage are excluded (ARB No. 43, Chapter 3A, paragraphs 4 and 6). A stake held to keep a supplier close is not a quick asset however liquid its market is.
Receivables enter net rather than gross. Accounts and notes receivable is caption 3 (17 CFR 210.5-02), and the allowance against it is reported on its own rather than folded into the balance, the presentation accounts receivable works through, so what the ratio can use is the two lines read together. Not every receivable qualifies even then. Receivables arising from unusual transactions, such as the sale of capital assets or loans to affiliates, officers or employees, which are not expected to be collected within twelve months are not current assets at all (ARB No. 43, Chapter 3A, paragraph 6).
Why Inventory and Prepaid Expenses Are Left Out
These two exclusions are the whole point of the measure, and they are where it parts company with the current ratio, though they are not the only current assets it leaves out.
Inventory sits at caption 6 (17 CFR 210.5-02) and stands two steps from cash rather than one. Inventory costs, upon sale of the products to which such costs attach, are converted into trade receivables and ultimately into cash again (ARB No. 43, Chapter 3A, paragraph 5). A business under pressure has to find a buyer before that balance pays anyone.
Prepaid expenses, caption 7 (17 CFR 210.5-02), never become cash at all. Prepaid expenses are not current assets in the sense that they will be converted into cash but in the sense that, if not paid in advance, they would require the use of current assets during the operating cycle (ARB No. 43, Chapter 3A, paragraph 4). A year of insurance bought in advance settles no invoice.
The Denominator
Total current liabilities is caption 21 (17 CFR 210.5-02), so the ratio inherits whatever the current split decided. Debt crosses into that total a slice at a time as it comes due, a reclassification redrawn at every close and worked through in long-term liabilities. A denominator carrying a stale current portion moves the answer with nothing else on the page changing.
A Worked Example
Say a client balance sheet at year end carries the current lines below.
Cash and cash items 120,000
Marketable securities 40,000
Accounts receivable, gross 310,000
Allowance for doubtful accounts (25,000)
Inventories 180,000
Prepaid expenses 30,000
Other current assets 20,000
Total current assets 675,000
Total current liabilities 500,000
quick assets 120,000 + 40,000 + (310,000 - 25,000) = 445,000
quick ratio 445,000 / 500,000 = 0.89
current ratio 675,000 / 500,000 = 1.35
Two readings of one balance sheet, and only one of them says current liabilities are covered.
The subtraction shortcut that circulates as the formula, current assets less inventory less prepaid expenses, does not reproduce that answer here.
675,000 - 180,000 - 30,000 = 465,000
465,000 / 500,000 = 0.93
The gap is the other current assets line, which is neither inventory nor a prepaid and is not a quick asset either. The shortcut matches the ratio only when nothing else is sitting in current assets, so build the numerator by adding the quick lines up rather than by subtracting the two everyone remembers.
Where the Quick Ratio Gets Written Into a Rule
Lending agreements are one place, though the covenant the standard describes there is written on working capital rather than on this ratio by name. Bond indentures, credit agreements, and preferred stock agreements commonly contain provisions restricting corporate actions which would effect a reduction or impairment of working capital, and many such contracts forego precise or uniform definitions and merely provide that current assets and current liabilities shall be determined in accordance with generally accepted accounting principles (ARB No. 43, Chapter 3A, paragraph 1). Working capital, sometimes called net working capital, is represented by the excess of current assets over current liabilities (ARB No. 43, Chapter 3A, paragraph 3), so it turns on the same classification lines this ratio does. Where the agreement is silent, the classification decides the covenant.
Federal programs that use the ratio write their own version of it, and the versions do not agree. On a change in ownership, an institution’s same-day balance sheet must demonstrate an acid test ratio of at least 1:1, calculated by adding cash and cash equivalents to current accounts receivable and dividing the sum by total current liabilities, with all related party receivables and other assets and all assets classified as intangibles excluded (34 CFR 668.176(d)(1)(i)(D)). That numerator carries no marketable securities at all, and it removes the related-party balances a filed balance sheet reports on their own line.
Public housing runs a third version. The quick ratio compares quick assets to current liabilities, quick assets are cash and assets that are easily convertible to cash and do not include inventory, current liabilities are those liabilities that are due within the next 12 months, and a quick ratio of less than one indicates that the project’s ability to make payments on a timely basis may be at risk (24 CFR 902.35).
Whichever version applies, the inputs come out of the close, so a reading taken before the receivable allowance is set and the bank reconciliation is cleared is measuring the close rather than the client.
Common Questions
There is no universal figure. A desirable ratio depends on the industry, which is the qualification net profit margin sets out and sources. A federal loan-guarantee rule that leans on this measure points at an industry benchmark rather than at a number, asking whether pro forma statements indicate the business meets or exceeds the median quartile, as identified in the Risk Management Association’s Annual Statement Studies or similar publication, for the current ratio, quick ratio, debt-to-worth ratio, and debt service coverage ratio (7 CFR 5001.105). A ratio of one is the level where quick assets exactly cover current liabilities, and it is the level federal rules reach for when they fix one at all.
It means quick assets cover three quarters of what falls due, so the remaining quarter has to come from outside quick assets: selling inventory, cash the business earns after the balance sheet date, or new borrowing. Collecting a receivable faster does not close the gap, because a collected receivable was already counted in the numerator and only changes which quick asset it sits in.
quick assets 75 / current liabilities 100 = 0.75
shortfall 100 - 75 = 25
Whether that is a problem depends on the industry and on the agreements the business has signed. Below one is treated as a warning where a federal program scores it, since a quick ratio of less than one indicates that the project’s ability to make payments on a timely basis may be at risk (24 CFR 902.35).
Quick assets are half again the size of current liabilities, so the business could settle every current liability out of cash, marketable securities and collectible receivables and still hold quick assets equal to half its current liabilities.
quick assets 150 / current liabilities 100 = 1.5
surplus 150 - 100 = 50, half of current liabilities
It says nothing about timing. A receivable collectible in ninety days and a payable due next week both sit in the ratio at face value.
The denominator is the same and the numerator is not. The current ratio uses total current assets; the quick ratio drops inventory and prepaid expenses, and drops anything else in current assets that will not turn into cash on its own. A balance sheet heavy in inventory therefore produces a comfortable current ratio and a thin quick ratio at the same time, off the same page.
Accountably places trained offshore accountants and tax preparers inside US CPA and EA firms, and a firm can put a block of its own balance sheet classification work through a trial task before anything client facing depends on it.
