What is working capital?

Working capital is the difference between your business's current assets and current liabilities. It shows how much cash and liquid resources you have available to cover short-term expenses and keep operations running.

A positive number means you have more assets than debts. A negative number signals potential cash flow problems.

Current assets and liabilities

Current assets are resources you can convert to cash within 12 months. This timeframe is based on a business's normal operating cycle. Accounting standards assume this to be one year if not otherwise identifiable:

• Cash and bank funds: money in your accounts
• Accounts receivable: payments customers owe you
• Inventory: stock you can sell
• Prepaid expenses: costs paid in advance
• Short-term investments: assets you can liquidate quickly
• Tax refunds: money owed to you by tax authorities

For more details, see current assets in the Xero glossary.

Current liabilities are debts you must pay within 12 months. According to international accounting standards, liabilities are classified as current when they are due to be settled within a 12-month period:

• Accounts payable: bills you owe to suppliers
• Loan payments: principal and interest due this year
• Deferred revenue: payments received for work not yet completed
• Accrued expenses: wages, bank fees, and other costs owed

For more details, see current liabilities in the Xero glossary.

How to calculate working capital

Calculating working capital takes one simple formula: subtract your current liabilities from your current assets.

To get accurate numbers, gather your projected assets and liabilities for the next 12 months. Accounting software like Xero makes this easy by pulling figures directly from your balance sheet and financial reports.

The working capital formula

A working capital formula example

Here's how a small business owner might calculate their working capital:

Example: Retail florist

1. Add up current assets for the next 12 months: $100,000
2. Add up current liabilities for the next 12 months: $75,000
3. Apply the formula: $100,000 − $75,000 = $25,000 working capital

This positive result means the florist has enough resources to cover short-term debts and invest in the business.

Working capital vs working capital ratio

Working capital and working capital ratio measure the same data differently:

• Working capital gives you a dollar amount (assets minus liabilities)
• Working capital ratio gives you a proportion (assets divided by liabilities)

The ratio helps you compare your financial position over time or against industry benchmarks. Small businesses generally consider a ratio between 1.2 and 2.0 healthy.

The importance of working capital in business

Working capital matters because it shows whether your business can pay its bills and invest in growth. It's one of the first things lenders and investors check when assessing your financial health. However, it's only one part of a company's total worth. Some experts estimate that up to 80% of enterprise value is hidden from balance sheet.

Strong working capital helps you:

• Cover day-to-day expenses: pay suppliers, staff, and overhead without borrowing
• Handle seasonal changes: manage slow periods without running out of cash
• Seize opportunities: invest in inventory, equipment, or marketing when the timing is right
• Build credibility: demonstrate financial stability to lenders, investors, and partners

Your working capital result indicates your financial flexibility.

Positive vs negative working capital

Your working capital result tells you how financially flexible your business is:

• Positive working capital: Your assets exceed your liabilities. You can pay your bills, cover unexpected costs, and reinvest in growth.
• Negative working capital: Your liabilities exceed your assets. You may struggle to pay debts without borrowing or raising funds. This signals potential financial trouble if it continues.
• Neutral working capital: Your assets and liabilities are roughly equal. This works if sales are steady, but leaves little room for unexpected expenses or investment.

Very high working capital isn't always ideal. It may mean you're not investing enough in growth or innovation.

Working capital examples in different businesses

Working capital needs vary by industry. A retail business with large inventory requirements needs more working capital than a service business with minimal stock. Understanding your industry's typical patterns helps you set realistic targets.

Working capital in construction and manufacturing

Construction and manufacturing businesses often face irregular cash flow due to long project timelines. You may need to pay for materials, subcontractors, and labour upfront but won't recover those costs until a project is complete. Accounting standards recognise these items as part of the working capital used in a normal operating cycle. They classify them as current liabilities even if settlement extends beyond 12 months.

Example: Building materials manufacturer

1. Current assets: cash ($100,000) + accounts receivable ($200,000) + inventory ($300,000) = $600,000
2. Current liabilities: accounts payable ($150,000) + short-term loans ($100,000) + accrued expenses ($50,000) = $300,000
3. Working capital: $600,000 − $300,000 = $300,000

This positive working capital means the manufacturer can cover its short-term obligations even in uncertain market conditions.

Working capital in service businesses

Service businesses like consultancies and agencies typically need less working capital than product-based businesses because they don't hold inventory.

However, service businesses still need working capital to:

• Cover payroll: pay staff while waiting for client payments
• Manage accounts receivable: bridge the gap between invoicing and receiving payment
• Fund project costs: pay for expenses before billing clients

Working capital in retail

Retail, wholesale, and hospitality businesses typically need higher working capital because they hold significant inventory. You need cash to buy stock in advance, especially before peak seasons.

To keep working capital healthy:

• Match inventory to demand: avoid tying up cash in slow-moving stock
• Monitor stock turnover: faster sales mean faster cash recovery
• Plan for seasonality: build reserves before busy periods

What is net working capital?

Net working capital (also called operating working capital) measures your operational efficiency by excluding cash and debt from the standard working capital formula.

The difference:

• Working capital: current assets minus current liabilities (includes all cash and debt)
• Net working capital: current assets (minus cash) minus current liabilities (minus debt)

When to use net working capital:

• Long-term planning: assess operational efficiency over time
• Business expansion: understand how efficiently you're using resources
• Low-margin industries: retail, manufacturing, and distribution businesses where operational efficiency drives profitability

The net working capital formula

Using the florist example from earlier, here's how to calculate net working capital:

Original figures:

• Current assets: $100,000 (includes $20,000 cash)
• Current liabilities: $75,000 (includes $10,000 loan debt)

Net working capital calculation:

1. Adjusted assets: $100,000 − $20,000 (cash) = $80,000
2. Adjusted liabilities: $75,000 − $10,000 (debt) = $65,000
3. Net working capital: $80,000 − $65,000 = $15,000

Working capital vs cash flow: what's the difference?

Working capital and cash flow both measure financial health, but they answer different questions:

• Working capital: How much is left after covering upcoming costs? (a snapshot of assets minus liabilities)
• Cash flow: How is money moving in and out? (tracks the timing of payments and receipts)

Cash flow shows your day-to-day cash position. Working capital shows your overall short-term financial flexibility.

FAQs on working capital

Common questions about working capital and how it affects your business.

What is a good working capital ratio for small businesses?

A good working capital ratio for small businesses is typically between 1.2 and 2.0. A ratio below 1.0 means you may not have enough assets to cover short-term debts. Service businesses generally need lower ratios than retailers with significant inventory.

How can I improve working capital ratio?

You can improve your working capital ratio by:

• Invoicing faster: send invoices immediately to reduce payment turnaround time
• Negotiating longer payment terms: ask suppliers for extended deadlines to slow cash outflows
• Offering early payment discounts: encourage customers to pay sooner
• Cutting non-essential spending: reduce overheads to increase your available assets

What happens if my working capital ratio is too low?

A low working capital ratio means your business may struggle to pay short-term debts. This is because liabilities are classified based on whether the business has the right to defer settlement for at least 12 months. This is a key factor impacting the ratio. If this continues, you risk insolvency. Consider speeding up receivables, reducing expenses, or seeking short-term financing to improve your position.

What is a working capital loan?

A working capital loan is short-term financing used to cover day-to-day operating expenses when your business faces a cash shortfall. It's typically a last resort after other improvement efforts haven't worked. Consult a financial adviser before taking on new debt.

Is working capital the same as liquidity?

Not quite. Liquidity measures how easily you can convert assets to cash to cover upcoming costs. Working capital measures how much remains after covering those costs. Both indicate financial health, but working capital gives you a dollar amount while liquidity focuses on accessibility.
