What is working capital and how do you calculate it?

Working capital is the difference between a company's current assets and current liabilities. The formula is: Working Capital = Current Assets - Current Liabilities. Current assets include cash, accounts receivable, inventory, and prepaid expenses. Current liabilities include accounts payable, short-term debt, and accrued expenses. Positive working capital means the business can cover its short-term obligations.

What is a good current ratio?

A current ratio above 2.0 is considered strong, indicating the company has twice as many current assets as current liabilities. A ratio between 1.5 and 2.0 is healthy. Between 1.0 and 1.5 is tight but still positive. Below 1.0 signals danger — the business may not be able to meet its short-term obligations. The ideal ratio varies by industry; capital-intensive industries often operate with lower ratios.

What is the quick ratio and how is it different from the current ratio?

The quick ratio (also called the acid-test ratio) is calculated as (Current Assets - Inventory) / Current Liabilities. It excludes inventory from current assets because inventory may not be quickly convertible to cash. This makes the quick ratio a more conservative measure of liquidity than the current ratio. A quick ratio of 1.0 or higher means the company can cover its obligations without selling inventory.

How does taking on short-term debt affect working capital?

Taking on short-term debt increases both cash (an asset) and short-term debt (a liability) by the same amount, so net working capital stays the same. However, the current ratio decreases because liabilities grow proportionally more. For example, if you have $450K assets and $250K liabilities (ratio 1.80), borrowing $50K changes it to $500K/$300K (ratio 1.67). Use the What-If tab to model this scenario.

How to Use This Calculator

Tab "Working Capital"

Enter your current assets (cash, accounts receivable, inventory, prepaid expenses) and current liabilities (accounts payable, short-term debt, accrued expenses). The calculator shows your net working capital and current ratio with a health rating.

Tab "Current & Quick Ratios"

Uses the same balance sheet data to compute three liquidity ratios: current ratio, quick ratio (excludes inventory), and cash ratio (cash only). Each ratio gets a rating: Strong (> 2.0), Healthy (1.5–2.0), Tight (1.0–1.5), or Danger (< 1.0).

Tab "What-If"

Model three common scenarios: take on short-term debt (adds to both cash and liabilities), collect receivables faster (converts receivables to cash), and increase or decrease inventory. See a side-by-side comparison of current vs projected working capital and ratios.

The Formulas

Working capital:
Working Capital = Current Assets − Current Liabilities

Current ratio:
Current Ratio = Current Assets / Current Liabilities

Quick ratio (acid-test ratio):
Quick Ratio = (Current Assets − Inventory) / Current Liabilities

Cash ratio:
Cash Ratio = Cash / Current Liabilities

Rating scale:
> 2.0 = Strong | 1.5–2.0 = Healthy | 1.0–1.5 = Tight | < 1.0 = Danger

All calculations are universal. No country-specific accounting standards or tax rules are applied. Results are point-in-time estimates based on the figures you enter.

Worked Examples

Example 1 — Healthy small business: $450K assets, $250K liabilities

A small business has $120K cash, $180K receivables, $100K inventory, $50K prepaid expenses. Liabilities: $130K payables, $80K short-term debt, $40K accrued expenses.

Total current assets$120K + $180K + $100K + $50K = $450,000

Total current liabilities$130K + $80K + $40K = $250,000

Working capital$450,000 − $250,000 = $200,000

Current ratio$450,000 / $250,000 = 1.80 (Healthy)

Quick ratio($450,000 − $100,000) / $250,000 = 1.40 (Tight)

Cash ratio$120,000 / $250,000 = 0.48 (Danger)

The current ratio looks healthy at 1.80, but the quick ratio (1.40) and cash ratio (0.48) reveal that much of the liquidity is tied up in inventory. If inventory cannot be sold quickly, the business could struggle to meet obligations.

Example 2 — Tight liquidity: $280K assets, $280K liabilities

A business with $30K cash, $80K receivables, $150K inventory, $20K prepaid faces $120K payables, $100K short-term debt, $60K accrued expenses.

Total current assets$30K + $80K + $150K + $20K = $280,000

Total current liabilities$120K + $100K + $60K = $280,000

Working capital$280,000 − $280,000 = $0

Current ratio$280,000 / $280,000 = 1.00 (Tight)

Quick ratio($280,000 − $150,000) / $280,000 = 0.46 (Danger)

Zero working capital means assets exactly equal liabilities — any unexpected expense or slow-paying customer could cause a cash crunch. The quick ratio at 0.46 confirms the business is heavily dependent on selling inventory to stay solvent.

Example 3 — What-If: healthy business takes on $50K short-term debt

Starting from Example 1 ($450K assets, $250K liabilities), the business borrows $50K to fund expansion.

New cash$120,000 + $50,000 = $170,000

New total assets$500,000

New short-term debt$80,000 + $50,000 = $130,000

New total liabilities$300,000

New working capital$500,000 − $300,000 = $200,000 (unchanged)

New current ratio$500,000 / $300,000 = 1.67 (Healthy, down from 1.80)

New quick ratio($500,000 − $100,000) / $300,000 = 1.33 (Tight, down from 1.40)

Net working capital stays the same because debt adds equally to assets and liabilities. But the ratios drop because the denominator grows proportionally more. The current ratio went from 1.80 to 1.67 — still healthy, but worth monitoring.

Understanding Working Capital

What Is Working Capital?

Working capital is the money available to fund day-to-day operations. It measures the gap between what a business owns in the short term (current assets) and what it owes in the short term (current liabilities). Positive working capital means the business can pay its bills, invest in growth, and handle unexpected expenses.

Why Ratios Matter More Than the Number

A business with $200K working capital sounds healthy, but context matters. If that business has $10M in liabilities, $200K is a razor-thin margin. The current ratio normalises working capital relative to liabilities, making it easier to compare across businesses of different sizes and industries.

Quick Ratio: The Acid Test

The quick ratio strips out inventory because it may take weeks or months to sell. A manufacturing company with $5M in raw materials cannot pay next week's payroll with steel beams. The quick ratio answers: can the business meet its obligations without selling inventory? A quick ratio above 1.0 means yes.

Cash Ratio: The Most Conservative

The cash ratio uses only cash and cash equivalents — no receivables, no inventory. It shows whether the business can pay all current liabilities right now, with cash on hand. Most businesses have a cash ratio below 1.0, which is normal. It becomes a concern when combined with a low quick ratio.

Industry Benchmarks

Ideal ratios vary by industry. Retail businesses often have current ratios near 1.0 because they turn inventory quickly. Software companies may have ratios above 3.0 because they have minimal inventory and receivables convert fast. Compare your ratios to industry peers, not just the generic scale.

Frequently Asked Questions

What is a good working capital ratio?▼

A current ratio between 1.5 and 2.0 is generally considered healthy. Above 2.0 is strong but may indicate the business is not using its assets efficiently. Below 1.0 means current liabilities exceed current assets, which is a warning sign. The ideal ratio depends on your industry and business model.

What is the difference between working capital and cash flow?▼

Working capital is a balance sheet snapshot: current assets minus current liabilities at a point in time. Cash flow measures the actual movement of money in and out of the business over a period. A company can have strong working capital but poor cash flow if receivables are growing faster than collections. Both metrics are important for assessing financial health.

Can a business have too much working capital?▼

Yes. Excess working capital (very high current ratio, like 4.0+) may mean the business is holding too much cash or inventory that could be invested for growth. Shareholders may view this as inefficient capital allocation. The goal is to have enough liquidity to operate safely without hoarding idle assets.

How do I improve my working capital?▼

Common strategies include: collecting receivables faster (shorter payment terms, early payment discounts), reducing inventory levels (just-in-time ordering), negotiating longer payment terms with suppliers, and converting short-term debt to long-term debt. The What-If tab lets you model some of these scenarios.

Does this calculator include country-specific data?▼

No. This is a universal working capital calculator that works with any currency. It uses standard financial ratios (current ratio, quick ratio, cash ratio) that are consistent across international accounting standards. No country-specific accounting rules or tax data are applied.
