Current Ratio
Current ratio tells you whether a company has enough short-term assets to cover its short-term debts. Above 1.0 is generally safe; below 1.0 is a red flag.
Definition
The current ratio is a liquidity metric that compares a company's current assets to its current liabilities. It answers the question: for every $1 of short-term obligations, how many dollars of short-term assets does the company have? A ratio above 1.0 indicates the company can cover its near-term liabilities.
Formula
Current Ratio = Current Assets / Current Liabilities

Above 1.0x — company can cover short-term debts
Quick (Acid-Test) Ratio
Like current ratio but excludes inventory — a stricter test
Current Assets Breakdown
Inventory is excluded because it may not be quickly convertible to cash. A retailer sitting on unsold goods has a weaker liquidity position than the current ratio suggests.

Liquidity by Industry
The gap between current and quick ratio reveals inventory dependence
Technology
Retail
Large gap (0.9x) — heavy inventory reliance
Manufacturing
Large gap (0.8x) — heavy inventory reliance
How to Interpret the Current Ratio
A current ratio of 1.5x means the company has $1.50 of current assets for every $1.00 of current liabilities. Generally, 1.5x–2.0x is considered healthy, but the ideal range varies by industry. Retailers often operate below 1.0x because they collect cash quickly, while manufacturers need higher ratios due to large inventory balances and slower collections.
Current Ratio vs. Quick Ratio
The current ratio includes all current assets, while the quick ratio excludes inventory and prepaid expenses. The quick ratio is more conservative because inventory may not be easily converted to cash. If a company's current ratio is strong but its quick ratio is weak, it suggests the company is heavily reliant on inventory to cover obligations.
Limitations and Context
A very high current ratio (above 3.0x) is not necessarily good — it may indicate the company is hoarding cash or has excess inventory it cannot sell. The current ratio is also a point-in-time snapshot and can be manipulated by timing payments. Always look at trends over multiple quarters and compare against industry peers.
Worked Example — With Real Numbers
A company has $800M in current assets (cash $200M, receivables $300M, inventory $250M, prepaid $50M) and $500M in current liabilities. Current Ratio = $800M / $500M = 1.6x. This means the company has $1.60 of liquid assets for every $1 of near-term obligations.
Key Takeaways
Current ratio measures short-term liquidity — current assets divided by current liabilities
A ratio above 1.0x means the company can cover short-term obligations; 1.5x–2.0x is typical
Compare across industry peers — ideal ratios vary significantly by sector
A very high ratio may signal inefficient use of assets, not just financial strength
Common Mistakes in Interviews
Saying a higher current ratio is always better — too high may mean inefficient capital allocation
Ignoring industry context — retail and tech companies often run below 1.0x by design
Confusing the current ratio with the quick ratio — the quick ratio excludes inventory
How Interviewers Test This
If asked about liquidity ratios, start with the current ratio formula, then mention the quick ratio as a more conservative alternative. Be ready to discuss what constitutes a 'good' ratio and why it varies by industry.
