Definition
The current ratio answers whether a business can cover obligations due within one year using assets expected to convert to cash within the same horizon.
It is widely cited in credit memos and internal dashboards alongside working capital and cash flow metrics.
Formula
Current ratio = Current assets ÷ Current liabilities.
Working capital = Current assets − Current liabilities. Working capital is an absolute dollar cushion; the current ratio is a proportional measure.
Interpretation
Below 1.0 (poor): current liabilities exceed current assets — potential liquidity stress without other funding sources.
Roughly 1.0–2.0 (adequate to strong): common operational range for many industrial businesses, with context by industry.
Well above 2.5 (potential excess idle assets): may indicate excess cash or slow-moving inventory not deployed productively.
Common mistakes
Treating a high ratio as always good — idle cash and bloated inventory inflate the numerator without improving operations.
Excluding short-term debt or misclassifying long-term portions of obligations.
Comparing ratios across industries without adjustment — retailers and software firms operate on different liquidity profiles.
Relying on the ratio alone without reviewing cash flow timing and covenant definitions.
Examples
Current assets $450,000 and current liabilities $200,000 yield a current ratio of 2.25 and working capital of $250,000 — generally strong for planning purposes.
If receivables grow while payables shrink, the ratio may improve temporarily even when cash collections weaken — pair with AR aging review.
Key takeaways
- Current ratio = current assets ÷ current liabilities.
- Interpret with industry norms and trend analysis.
- Combine with working capital, cash flow, and quick ratio when available.

FAQ
- What is a healthy current ratio?
- Many analysts cite 1.5–2.5 for capital-intensive businesses, but appropriate levels vary. Trend and peer comparison matter more than a single rule.
- How is this different from the quick ratio?
- The quick ratio excludes inventory and other less liquid current assets. It is stricter and better for near-cash stress testing.
