Acid-Test Ratio (Quick Ratio)
The acid-test ratio, also called the quick ratio, measures a company's ability to pay its current liabilities using only its most liquid assets. It is calculated by adding cash, cash equivalents, marketable securities, and accounts receivable, then dividing by current liabilities. Inventory and prepaid expenses are deliberately excluded because they cannot always be converted to cash quickly.
Problem & Application
For owner-operated businesses with seasonal revenue, such as campgrounds or short-term rental operators, the acid-test ratio is a clearer liquidity signal than the broader current ratio because it ignores inventory that may sit unsold in the off-season. A ratio below 1.0 means a business cannot meet near-term obligations without selling inventory or raising new cash, which is a warning sign heading into a slow period. Lenders and investors often look at this number before extending credit.
In Short
Tracking the acid-test ratio gives operators an honest read on short-term solvency before a cash crunch forces a hard decision. It is a fast, repeatable health check that belongs in any monthly close.
