Quick Ratio Calculator
Calculates the quick ratio (acid-test ratio) by dividing liquid assets — cash, marketable securities, and accounts receivable — by current liabilities.

Formula
Cash is the amount of cash and cash equivalents on hand. Marketable Securities are short-term, liquid investments easily convertible to cash. Accounts Receivable are amounts owed by customers expected to be collected within 90 days. Current Liabilities are all financial obligations due within one year. Unlike the current ratio, inventory and prepaid expenses are intentionally excluded because they cannot be rapidly converted to cash.

How it works
The quick ratio is a stricter measure of short-term liquidity than the current ratio. While the current ratio includes all current assets — among them inventory and prepaid expenses — the quick ratio deliberately excludes these because they may take weeks or months to convert into usable cash. This makes the acid-test ratio a more conservative and often more meaningful signal of a firm's immediate financial resilience.
The formula sums three highly liquid asset categories: cash and cash equivalents (bank balances, money market funds), marketable securities (short-term bonds, Treasury bills, liquid equity positions), and accounts receivable (invoices owed by customers, typically collectible within 30–90 days). This total is then divided by current liabilities — all obligations the company must settle within 12 months, including accounts payable, short-term debt, accrued expenses, and the current portion of long-term debt.
A quick ratio of 1.0 means the company has exactly $1 of liquid assets for every $1 of current liabilities — a breakeven position. A ratio above 1.0 indicates a liquidity buffer; a ratio significantly above 2.0 may suggest idle cash that could be deployed more productively. Ratios below 1.0 are common in industries like retail (which carry large inventories) but can be a warning sign in service or tech sectors where inventories are minimal. Lenders and analysts typically look for a minimum quick ratio of 1.0 when assessing creditworthiness.
Worked example
Consider a mid-sized manufacturing company with the following balance sheet items at year-end:
Cash & Cash Equivalents: $120,000
Marketable Securities: $45,000
Accounts Receivable: $85,000
Current Liabilities: $200,000
Step 1 — Sum liquid assets:
$120,000 + $45,000 + $85,000 = $250,000
Step 2 — Divide by current liabilities:
$250,000 ÷ $200,000 = 1.25
The company has a quick ratio of 1.25, meaning it holds $1.25 in liquid assets for every $1 of short-term obligations. This represents a $50,000 liquidity surplus and suggests the company can comfortably cover near-term liabilities without relying on inventory liquidation. This would generally be viewed positively by creditors and bond rating agencies.
Limitations & notes
The quick ratio is a point-in-time snapshot and does not capture the timing mismatch between when receivables are actually collected and when liabilities fall due. A company with $500,000 in accounts receivable that are 90 days out but $400,000 in payables due next week could still face a cash crisis despite a healthy ratio. Additionally, the quality of accounts receivable matters enormously — receivables that are unlikely to be collected should not be included, but this requires judgment beyond what balance sheet figures reveal. The ratio also ignores credit facilities and revolving lines of credit that many companies use as genuine liquidity buffers. In capital-intensive industries such as retail, grocery, or automotive manufacturing, a sub-1.0 quick ratio is normal and sustainable due to rapid inventory turnover. Always interpret the quick ratio in the context of the industry benchmark, the trend over time, and supplementary cash flow data.
Frequently asked questions
What is a good quick ratio for a company?
A quick ratio of 1.0 or above is generally considered adequate, as it means liquid assets cover current liabilities dollar-for-dollar. Ratios between 1.0 and 2.0 are seen as healthy across most industries. However, norms vary — tech and service companies often exceed 1.5, while retail companies frequently operate below 1.0 due to heavy inventory reliance.
What is the difference between the quick ratio and the current ratio?
The current ratio includes all current assets — cash, securities, receivables, inventory, and prepaid expenses — divided by current liabilities. The quick ratio strips out inventory and prepaid expenses, focusing only on assets that can be converted to cash quickly. This makes the quick ratio a more conservative and stricter liquidity measure, particularly useful when inventory is slow-moving or illiquid.
Why is the quick ratio also called the acid-test ratio?
The term 'acid test' comes from 19th-century gold assaying, where nitric acid was used to test whether a metal was genuine gold — only real gold withstood the test. Applied to finance, the acid-test ratio similarly separates companies with genuine short-term financial strength from those that depend on inventory sales to meet obligations.
Should I include all accounts receivable in the quick ratio?
Best practice is to include only accounts receivable expected to be collected within 90 days. Long-term receivables, disputed invoices, or receivables from financially distressed customers should ideally be excluded or adjusted for. Some analysts use net receivables (after allowance for doubtful accounts) from the balance sheet for a more conservative calculation.
Can the quick ratio be too high?
Yes. A very high quick ratio — say above 3.0 or 4.0 — can suggest the company is holding excessive idle cash or not investing its liquid assets efficiently. While this is better than insolvency risk, it may indicate suboptimal capital allocation, and investors may prefer the company use surplus cash for dividends, share buybacks, or strategic investments.
