Acid-test ratio
Quick ratio
The quick ratio, also known as the acid-test ratio, measures a company's ability to pay its short-term obligations using only its most liquid assets. It excludes inventory from current assets, providing a stricter liquidity test than the current ratio.

What is the quick ratio?
The quick ratio measures whether a company can cover its current liabilities using only its most liquid assets, those that can be converted to cash quickly without significant loss in value. By excluding inventory and prepaid expenses, it provides a more conservative view of liquidity than the current ratio.
This distinction matters because inventory can be slow to liquidate and may sell at a discount under pressure. A retailer sitting on months of unsold inventory may have a strong current ratio but a weak quick ratio, revealing the true liquidity position. For SaaS and service businesses with no physical inventory, the quick ratio and current ratio are typically very similar.
Note: the financial quick ratio should not be confused with the SaaS quick ratio, which measures revenue growth efficiency. They share a name but measure entirely different things.
Quick ratio in a metric tree
Benchmarks
| Range | Interpretation |
|---|---|
| Above 1.5 | Very strong liquidity. Can easily cover short-term obligations with liquid assets. |
| 1.0 to 1.5 | Healthy. Sufficient liquid assets to cover current obligations. |
| 0.5 to 1.0 | Tight liquidity. May need to rely on future revenue or credit facilities. |
| Below 0.5 | Liquidity risk. May struggle to meet short-term obligations without selling assets or raising capital. |
How to improve the quick ratio
- 1
Increase cash reserves
Retain earnings, collect receivables faster, or raise capital to build the cash component.
- 2
Reduce current liabilities
Refinance short-term debt to long-term, negotiate better payment terms, or pay down obligations.
- 3
Improve receivables quality
Tighten credit policies and collection processes to ensure receivables are collectible and timely.
Common mistakes
- 1
Confusing with the SaaS quick ratio
The SaaS quick ratio (new + expansion MRR) / (churned + contraction MRR) is a completely different metric. Context determines which is being referenced.
- 2
Including non-collectible receivables
Aged or disputed receivables inflate the quick ratio. Use net receivables after allowance for doubtful accounts.

Current Ratio
Liquidity measure
Financial MetricsMetric Definition
Current Ratio = Current Assets / Current Liabilities
The current ratio measures a company's ability to pay its short-term obligations using its short-term assets. It is one of the most widely used liquidity metrics for assessing whether a business has sufficient resources to meet its near-term financial commitments.
Working Capital
Short-term financial health
Financial MetricsMetric Definition
Working Capital = Current Assets - Current Liabilities
Working capital is the difference between a company's current assets and current liabilities. It measures the short-term liquidity available to fund day-to-day operations and is a fundamental indicator of financial health.
SaaS Quick Ratio
Revenue growth efficiency
SaaS MetricsMetric Definition
SaaS Quick Ratio = (New MRR + Expansion MRR) / (Churned MRR + Contraction MRR)
The SaaS quick ratio measures the efficiency of MRR growth by comparing revenue gained (new + expansion) to revenue lost (churned + contraction). A high quick ratio means the business is growing efficiently without relying on brute-force acquisition to outrun churn.
