# Working Capital Calculator

Calculate working capital, current ratio, and quick ratio to assess short-term liquidity. Analyze a company's ability to pay its obligations. Free tool.

## What this calculates

Evaluate a company's short-term financial health with our working capital calculator. Enter current assets, current liabilities, and inventory to calculate working capital, the current ratio, and the quick ratio (acid test).

## Inputs

- **Current Assets** ($) — min 0 — Total current assets (cash, receivables, inventory, etc.).
- **Current Liabilities** ($) — min 0 — Total current liabilities (payables, short-term debt, etc.).
- **Inventory** ($) — min 0 — Total inventory value (used for quick ratio calculation).

## Outputs

- **Working Capital** — formatted as currency — Current assets minus current liabilities. Positive means the company can cover short-term obligations.
- **Current Ratio** — Current assets divided by current liabilities. Above 1.0 indicates adequate liquidity.
- **Quick Ratio (Acid Test)** — Current assets minus inventory, divided by current liabilities. A stricter liquidity measure.
- **Working Capital Ratio** — formatted as percentage — Working capital as a percentage of current assets.

## Details

Working capital is the difference between a company's current assets and current liabilities. It represents the funds available for day-to-day operations and is a fundamental measure of short-term financial health. The formula is simply: Working Capital = Current Assets - Current Liabilities. Positive working capital means the company can pay its short-term obligations; negative working capital signals potential liquidity problems.

The current ratio (Current Assets / Current Liabilities) expresses this relationship as a ratio. A current ratio above 1.0 means the company has more current assets than current liabilities. Most analysts consider a ratio between 1.5 and 3.0 to be healthy, though this varies by industry. Very high ratios may indicate inefficient use of assets.

The quick ratio (also called the acid test) is a stricter measure that excludes inventory from current assets: (Current Assets - Inventory) / Current Liabilities. Inventory is excluded because it may not be easily convertible to cash. A quick ratio above 1.0 suggests the company can meet its short-term obligations without relying on inventory sales. This metric is especially important for businesses with slow-moving inventory.

## Frequently Asked Questions

**Q: What is a good current ratio?**

A: A current ratio between 1.5 and 3.0 is generally considered healthy. Below 1.0 means the company cannot cover its short-term liabilities with current assets, which is a red flag. Above 3.0 may indicate the company is not efficiently using its assets. However, acceptable ratios vary significantly by industry.

**Q: What is the quick ratio?**

A: The quick ratio (acid test) measures a company's ability to pay short-term liabilities using only its most liquid assets, excluding inventory. The formula is (Current Assets - Inventory) / Current Liabilities. A ratio above 1.0 means the company can meet obligations without selling inventory. It is considered a more conservative test of liquidity than the current ratio.

**Q: Can negative working capital be acceptable?**

A: In certain business models, yes. Companies like Amazon and Walmart sometimes operate with negative working capital because they collect from customers before paying suppliers. This is actually a sign of operating efficiency when it reflects strong supplier negotiations and fast inventory turnover. However, for most companies, persistent negative working capital is a warning sign.
