Quick Ratio
A strict liquidity measure comparing the most liquid assets — cash, investments, and receivables — to current liabilities, excluding inventory.
The quick ratio (also called the acid-test ratio) is a more stringent liquidity measure than the current ratio, assessing whether a company can meet its short-term obligations using only its most liquid assets — cash, short-term marketable securities, and accounts receivable — explicitly excluding inventory (which may not be rapidly convertible to cash) and other less-liquid current assets like prepaid expenses.
Quick Ratio = (Cash + Short-term Investments + Accounts Receivable) ÷ Current Liabilities
Alternatively: Quick Ratio = (Current Assets − Inventory − Prepaid Expenses) ÷ Current Liabilities
For a company with $2M cash, $1M in short-term investments, $3M in accounts receivable, and $4M in current liabilities: Quick Ratio = ($2M + $1M + $3M) ÷ $4M = 1.5.
A quick ratio above 1.0 indicates the company can cover all current liabilities with liquid assets alone. Below 1.0 suggests it may need to sell inventory, secure additional financing, or liquidate other assets to meet near-term obligations — a potential warning sign, particularly for companies with slow-moving or illiquid inventory.
The quick ratio is most meaningful for industries where inventory conversion time is significant: manufacturers, retailers, and distributors with slow-moving inventory. For service businesses and SaaS companies with no inventory, quick ratio equals current ratio and is simply another term for the same metric.
Historically, a quick ratio of 1.0 was considered the minimum for comfortable liquidity. However, companies with strong credit lines, predictable cash flows, or business models that collect cash quickly can operate with quick ratios below 1.0 without distress. As with all ratios, trend analysis and peer comparison are more useful than absolute thresholds.
FAQs
Should receivables always be included in the quick ratio?
Standard quick ratio includes all accounts receivable. But in practice, not all AR is equally liquid — highly aged receivables (90+ days) may be uncollectible. Some analysts use only current receivables (under 30 days) for a conservative quick ratio. The quality of AR matters: a quick ratio of 1.5 with 60% of AR over 60 days past due is materially weaker than the same ratio with fresh receivables.
Which is more important — current ratio or quick ratio?
For asset-light businesses (tech, services): quick ratio = current ratio since there's no inventory, making both equivalent. For inventory-heavy businesses: quick ratio is more conservative and meaningful for assessing true cash-in-crisis liquidity. Use current ratio for general working capital assessment and quick ratio to stress-test whether the business can survive a demand shock that prevents inventory liquidation.
What is the cash ratio and when is it used?
The cash ratio (Cash + Short-term Investments) ÷ Current Liabilities is the most stringent liquidity test — it excludes even receivables, assessing whether a company can meet obligations with only immediately available cash. Used in extreme distress scenarios or by lenders assessing worst-case collateral coverage. Most healthy businesses have cash ratios below 1.0 — cash ratios above 1.0 may indicate excessive cash hoarding.
