Current Ratio
A liquidity ratio measuring a company's ability to pay short-term obligations using current assets, calculated as current assets divided by current liabilities.
The current ratio is a liquidity metric that measures a company's ability to meet its short-term obligations (due within one year) using its short-term assets (also convertible to cash within one year). It is the most widely used liquidity ratio and provides a quick snapshot of near-term financial health.
Current Ratio = Current Assets ÷ Current Liabilities
Current assets typically include cash, short-term investments, accounts receivable, inventory, and prepaid expenses. Current liabilities include accounts payable, accrued expenses, short-term debt, current portion of long-term debt, and deferred revenue (if current).
For a company with $5M in current assets and $3M in current liabilities: Current Ratio = $5M ÷ $3M = 1.67, meaning the company has $1.67 in current assets for every $1.00 of current liabilities.
Interpreting current ratios: Below 1.0 means current liabilities exceed current assets — the company may struggle to meet obligations due within the next year without additional financing. A ratio of 1.0–1.5 provides some buffer but may be tight in stress scenarios. A ratio of 1.5–3.0 is generally considered healthy for most industries. Above 3.0 may indicate excess cash or slow inventory turnover — potentially inefficient capital deployment.
Context matters significantly: Retail businesses with fast inventory turnover (Walmart operates below 1.0x) can function efficiently with low current ratios. Manufacturers with slow-moving inventory need higher ratios as cushion. Service and subscription businesses with deferred revenue as a current liability may show low current ratios while being fundamentally healthy.
A sharp decline in current ratio is a warning signal — investigate whether it's driven by operational issues (slower receivables collection, excess payables), strategic cash deployment (acquisitions, buybacks), or financial distress (burning through reserves).
FAQs
What is the difference between current ratio and quick ratio?
The quick ratio (acid-test ratio) excludes inventory from current assets, calculated as (Cash + Short-term Investments + Accounts Receivable) ÷ Current Liabilities. Inventory may not be quickly convertible to cash in an emergency, so the quick ratio provides a more stringent liquidity test. For service businesses with no inventory, current and quick ratios are identical. For manufacturers with large inventory, the quick ratio may be significantly lower.
Can a company with a current ratio below 1.0 be financially healthy?
Yes — many fundamentally healthy businesses operate with current ratios below 1.0. Businesses with predictable recurring revenue, strong credit facilities, or business models that collect cash before paying obligations (subscription SaaS, retail that collects before paying suppliers) can maintain low current ratios sustainably. Amazon has historically operated with current ratios below 1.0 due to its efficient working capital management.
Should current ratio include deferred revenue?
Yes — current deferred revenue (expected to be earned within the next year) is correctly included as a current liability. However, it's a non-cash liability — there's no cash outflow associated with it; the obligation is to deliver service. Some analysts adjust the current ratio by excluding deferred revenue, arguing that it's not a 'cash-demanding' liability. Both versions provide useful perspective; consistency in methodology matters.
