A good acid-test ratio is 1.0 or higher, which means a business holds at least one dollar of liquid assets for every dollar it owes in the next 12 months. That threshold is the general benchmark, but the “good” number for any specific company depends on its industry. A discount retailer can run healthy at 0.35; a software company at the same level would be in trouble.1Business Development Bank of Canada – BDC. Acid-Test Ratio
How the Ratio Is Calculated
The acid-test ratio, also called the quick ratio, uses this formula:
Acid-Test Ratio = (Cash + Cash Equivalents + Short-Term Investments + Accounts Receivable) รท Current Liabilities
The numerator captures only assets a company can turn into cash quickly, typically within 90 days. The denominator includes every obligation due within one year: accounts payable, accrued wages, and the portion of any long-term debt maturing in the next 12 months. Inventory and prepaid expenses are deliberately left out. Selling inventory under time pressure usually means accepting steep discounts, and prepaid items like insurance premiums cannot be reclaimed to pay other bills.
The result tells you how many dollars of liquid assets stand behind each dollar of near-term debt. A company with $150,000 in cash, short-term investments, and receivables against $120,000 in current liabilities has a ratio of 1.25.
Reading the Number
At or Above 1.0
A ratio of 1.0 or higher is the standard benchmark for financial health. At this level, a company can pay off every current liability using only its most liquid assets, without selling inventory or taking on new debt. That cushion gives management breathing room when revenue dips or a major customer pays late.
Below 1.0
A ratio under 1.0 means liquid assets do not cover short-term debts. The company would have to rely on inventory sales, new borrowing, or other outside financing to stay current. This is not automatically a crisis. Many retailers and grocery chains operate below 1.0 because cash registers bring in money daily. It does, however, flag higher risk for lenders reviewing creditworthiness, and the further below 1.0 the ratio drops, the more the business depends on uninterrupted sales.
Well Above 1.0
A ratio of 2.0, 3.0, or higher signals extreme short-term safety, but it can raise a different concern. A company sitting on idle cash may be missing opportunities to reinvest in growth, pay down long-term debt, fund acquisitions, or return money to shareholders through dividends or buybacks. Balancing safety against productive use of capital is a core management judgment.
Industry Benchmarks
Because a “good” ratio depends so heavily on the sector, comparing a company to its direct peers gives a more useful picture than measuring it against a blanket 1.0 target. Businesses with fast-turning inventory and daily cash receipts thrive at lower ratios. Capital-intensive or project-based companies typically need higher liquidity buffers. As of early 2026, average quick ratios across selected sectors show how wide the range runs:
- Brick-and-mortar retail: Ratios often fall between 0.3 and 0.5. Discount stores average around 0.29, home improvement retailers around 0.39, and specialty retailers around 0.52. These businesses collect payment at the register and turn inventory rapidly, so low liquid reserves are normal.
- Technology: Ratios typically range from about 1.2 to 2.0. Semiconductor companies average near 1.97, and software companies cluster around 1.5. High recurring revenue and low physical inventory drive these elevated numbers.
- Manufacturing: Ratios generally sit between 0.8 and 1.4, depending on the subsector. Chemical manufacturers average around 1.13, steel producers around 1.43, and packaging companies around 0.79.
- Healthcare and biotech: Some of the widest variation appears here. Biotechnology firms average roughly 4.85, reflecting large cash reserves raised through equity funding, while general drug manufacturers average closer to 0.89.
A discount retailer at 0.35 can be perfectly healthy. A software company at the same level would be a red flag. Peer comparison is what turns the raw number into useful information.
What the Ratio Signals to Creditors and Investors
Lenders and investors look at the acid-test ratio to gauge how likely a company is to meet its financial commitments. A strong ratio tells a creditor the business can handle debt payments without being forced to liquidate equipment or property at fire-sale prices. Companies that maintain healthy quick ratios tend to secure more favorable borrowing terms and lower interest rates because they represent less default risk.
A low ratio can prompt lenders to tighten credit terms, require collateral, or charge higher interest. For investors, the ratio is one piece of a broader liquidity picture, and a declining acid-test ratio over several consecutive quarters can be an early warning sign of cash flow problems even when the company remains profitable on paper. Interest rates matter here too. With the federal funds rate at 3.5 to 3.75 percent as of early 2026, borrowing to cover short-term gaps is more expensive, and strong internal liquidity is worth more.2Federal Reserve Board.

Where the Ratio Can Mislead
The acid-test ratio is a snapshot taken at one moment, the date on the balance sheet. It does not show whether liabilities come due tomorrow or ten months from now, and it does not reveal how steadily cash is flowing in. A company could post 1.2 on December 31 and face a large vendor payment on January 5 that drains its liquidity.
Receivables quality is another blind spot. The ratio treats every dollar of accounts receivable as equally collectible, but some of that money may be 90 or more days overdue and unlikely to arrive. An aging report that breaks receivables into categories by how long they have been outstanding gives a clearer view of how much cash will actually materialize.
The ratio also says nothing about a company’s access to credit lines, its future revenue, or its cash conversion cycle. Two companies with identical acid-test ratios can have very different liquidity risks if one collects receivables in 15 days and the other takes 90. Pairing the ratio with cash flow statements, aging reports, and trend analysis over multiple periods fills in what the single number leaves out.3Harvard Business School Online. How to Calculate and Use Liquidity Ratios
Moving a Low Ratio Up
If a company’s acid-test ratio falls below a comfortable level for its industry, several practical steps can raise it. They work by either increasing liquid assets in the numerator or reducing current liabilities in the denominator.
- Speed up receivables collection. Invoice as soon as goods or services are delivered rather than batching invoices at month’s end. Shortening payment terms from “net 30” to “due upon receipt” and offering a small early-payment discount of 1 to 2 percent can accelerate cash inflow. Reminders a week before and on the day an invoice is due also shorten the average collection period.
- Sell underutilized or obsolete assets. Equipment, vehicles, or obsolete inventory sitting idle can be converted into cash. Even selling at a discount increases the cash side of quick assets.
- Pay down current liabilities. Using available cash to reduce accounts payable or short-term debt lowers the denominator. This helps only when the ratio is already near or above 1.0; below that, spending cash to pay off cheaper liabilities can make the ratio worse.
- Refinance short-term debt into long-term debt. Moving a loan’s maturity from under one year to over one year shifts it out of current liabilities entirely, improving the ratio without requiring additional cash.
- Delay non-essential purchases. Postponing capital expenditures or large inventory orders that would drain cash preserves liquid assets in the short term.
These tactics work best in combination. A company that tightens collections while refinancing a short-term note into a longer facility improves both sides of the ratio at once.
