Quick Ratio (Acid-Test Ratio)

Short answer

Quick Ratio (also called the Acid-Test) is cash + receivables + marketable securities divided by current liabilities. Unlike Current Ratio, it excludes inventory — so it answers a stricter question: could you pay every short-term obligation today without selling product?

Worth quotingBanks routinely covenant Quick Ratio ≥ 1.0× for commercial credit lines — falling below can trigger a technical default even if revenue is growing.

Formula

Quick Ratio = (Current Assets − Inventory) / Current Liabilities

Take current assets, subtract inventory, then divide by current liabilities. This shows whether you can pay short-term bills without selling product.

Why it matters

For inventory-heavy businesses (retail, e-commerce, manufacturing) the current ratio can look fine while the business is actually cash-poor. Quick ratio strips that out and shows the truth.

Common questions about Quick Ratio (Acid-Test Ratio)

What is the quick ratio?+

Quick Ratio = (Cash + Receivables + Marketable Securities) ÷ Current Liabilities. It measures whether a business can pay every short-term obligation immediately, without selling inventory.

What is a good quick ratio?+

1.0× or higher is the institutional benchmark — it means liquid assets fully cover current liabilities. Capital-intensive businesses (manufacturing, distribution) often run below 1.0 because inventory is the biggest current asset. Service businesses should clear 1.0× comfortably.

Quick ratio vs current ratio — what's the difference?+

Current Ratio includes inventory in current assets. Quick Ratio excludes it. Quick Ratio is the stricter test because inventory may not convert to cash quickly — especially in retail, restaurants, or seasonal businesses.

Why do lenders use the quick ratio?+

Quick Ratio strips out inventory and prepaid expenses, leaving only assets that are truly liquid within 90 days. For working-capital revolvers, banks want to see real cash + AR available — not inventory that might sit unsold for months.
