Current ratio

The Current ratio is a liquidity ratio that measures an entity's ability to meet its short-term liabilities using its current assets.

The ratio is calculated as:

$\text{Current Ratio}=\frac{\text{Current Assets}}{\text{Current Liabilities}}$

where:

• $\text{Current Assets}$ = assets expected to be realized, sold, or consumed within the applicable short-term period;
• $\text{Current Liabilities}$ = obligations expected to be settled within the applicable short-term period.

Interpretation

The current ratio indicates the amount of current assets available for each unit of current liabilities.

A simplified interpretation is:

$\text{Current Ratio}>1\to \text{Current Assets}>\text{Current Liabilities}$

Conversely:

$\text{Current Ratio}<1\to \text{Current Assets}<\text{Current Liabilities}$

A current ratio of 1 indicates:

$\text{Current Assets}=\text{Current Liabilities}$

A higher current ratio generally indicates a larger short-term asset buffer relative to current liabilities, although an excessively high ratio may also indicate inefficient use of working capital.

Example

Suppose a company has $120 million of current assets and $80 million of current liabilities.

The current ratio is:

$\text{Current Ratio}=\frac{\mathrm{\$}120\text{ million}}{\mathrm{\$}80\text{ million}}=1.5$

The company therefore has $1.50 of current assets for every $1 of current liabilities.

Components of current assets

Current assets can include:

• cash and cash equivalents;
• accounts receivable;
• inventory;
• short-term investments;
• other assets expected to be realized within the applicable short-term period.

The composition of current assets varies among businesses and accounting frameworks.

A simplified relationship is:

$\text{Current Assets}=\text{Cash}+\text{Receivables}+\text{Inventory}+\text{Other Current Assets}$

Components of current liabilities

Current liabilities can include:

• accounts payable;
• short-term borrowings;
• accrued expenses;
• current portions of long-term debt;
• other obligations due within the applicable short-term period.

A simplified relationship is:

$\text{Current Liabilities}=\text{Accounts Payable}+\text{Short-Term Debt}+\text{Accrued Obligations}+\text{Other Current Liabilities}$

Current ratio and quick ratio

The current ratio includes inventory and other current assets, whereas the Quick ratio generally excludes assets that may be less readily converted into cash.

The current ratio is:

$\text{Current Ratio}=\frac{\text{Current Assets}}{\text{Current Liabilities}}$

The quick ratio is:

$\text{Quick Ratio}=\frac{\text{Quick Assets}}{\text{Current Liabilities}}$

When quick assets are a subset of current assets:

$\text{Quick Assets}\subseteq \text{Current Assets}$

and, using the same denominator:

$\text{Quick Ratio}\le \text{Current Ratio}$

Current ratio and working capital

The current ratio is related to Working capital, which is calculated as:

$\text{Working Capital}=\text{Current Assets}-\text{Current Liabilities}$

The two measures provide different information.

$\text{Current Ratio}=\frac{\text{Current Assets}}{\text{Current Liabilities}}$

whereas:

$\text{Working Capital}=\text{Current Assets}-\text{Current Liabilities}$

The current ratio expresses liquidity as a relative measure, while working capital represents the absolute difference between current assets and current liabilities.

Current ratio and liquidity risk

The current ratio can provide an indication of an entity's short-term liquidity position but does not fully measure Liquidity risk.

A simplified relationship is:

$\text{Current Assets}\to \text{Potential Short-Term Liquidity}$

The ratio does not necessarily indicate:

• the timing of cash inflows and outflows;
• the quality or collectability of receivables;
• the liquidity of inventory;
• restrictions on cash;
• access to external financing;
• unexpected cash requirements;
• market liquidity conditions.

Consequently, the current ratio is generally considered alongside cash-flow analysis and other liquidity measures.

Limitations

The current ratio has several limitations.

A high current ratio does not necessarily indicate strong liquidity because a substantial proportion of current assets may consist of slow-moving inventory or receivables that are difficult to collect.

Similarly, a low current ratio does not necessarily indicate financial distress if an entity has predictable cash flows, rapid inventory turnover, or reliable access to financing.

The ratio is also generally calculated at a specific reporting date and may therefore be affected by seasonal or temporary changes in the entity's balance sheet.

A simplified distinction is:

$\text{Current Ratio}\to \text{Balance-Sheet Liquidity Measure}$

$\text{Cash-Flow Analysis}\to \text{Timing and Sustainability of Cash Availability}$

Industry differences

The appropriate current ratio can vary substantially among industries.

Businesses with rapid inventory turnover and predictable cash flows may operate with a lower current ratio, while businesses with longer operating cycles may require a larger current-asset buffer.

Consequently, current ratios are often more informative when compared with:

• historical ratios for the same entity;
• industry averages;
• comparable companies;
• changes in working-capital requirements.
