Key takeaways

• Calculate your working capital by subtracting current liabilities from current assets to determine if you have enough money to cover day-to-day expenses and fund growth opportunities.
• Maintain a working capital ratio between 1.2 and 2.0 for optimal financial health, as ratios below 1.0 signal potential cash flow problems while ratios above 2.0 may indicate you're not reinvesting enough in your business.
• Improve your working capital position by sending invoices immediately, negotiating longer payment terms with suppliers, and managing inventory levels to free up cash without leaving yourself understocked.
• Monitor both working capital and cash flow regularly, as working capital shows your overall financial health over 12 months while cash flow tracks daily money movement to ensure you can pay immediate bills.

What is working capital?

Working capital is the money your business has available to cover day-to-day expenses. You calculate it by subtracting current liabilities from current assets over a 12-month period, although if a company's operating cycle is more than 12 months, you use that longer period instead.

A positive result means you have surplus funds. A negative result signals a potential shortfall.

Current assets and liabilities

Current assets are resources you can convert to cash within 12 months:

• Cash and bank funds: money readily available in accounts
• Accounts receivable: payments customers owe you
• Inventory: stock you can sell
• Prepaid expenses: costs paid in advance, like insurance
• Short-term investments: assets you can liquidate quickly
• Tax refunds: money the government owes you

Current liabilities are obligations you must pay within 12 months:

• Accounts payable: money you owe suppliers
• Loan payments: principal and interest due within the year
• Deferred revenue: payments you've received for services you haven't yet delivered
• Accrued expenses: wages, bank fees, and other costs not yet paid

The importance of working capital in business

Working capital matters because it shows whether your business can pay its bills and fund growth. A healthy working capital position helps you handle unexpected expenses and seasonal slowdowns.

Working capital helps you:

• Operational stability: covers daily expenses like payroll and supplies
• Financial resilience: provides a buffer for market fluctuations
• Growth potential: funds expansion without taking on debt
• Lender confidence: banks and investors use it to assess your financial health

Positive vs negative working capital

Your working capital result tells you where your business stands financially:

• Positive working capital: Current assets exceed current liabilities. You can pay your bills and reinvest surplus funds into growth.
• Negative working capital: Current liabilities exceed current assets. You may need to borrow or raise funds to meet obligations. Ongoing negative working capital can signal financial trouble, as a ratio below 1.0 can lead to a potential liquidity problem.
• Neutral working capital: Assets and liabilities are roughly equal. This works if you convert inventory to cash quickly, but it leaves little room for unexpected costs.

Keep in mind that extremely high working capital isn't ideal either. It may suggest you're not reinvesting enough in the business.

How to calculate working capital

To calculate working capital:

1. Gather your current asset figures for the next 12 months.
2. Gather your current liability figures for the next 12 months.
3. Subtract current liabilities from current assets.

Accounting software makes this easier. You can pull the numbers directly from your balance sheet and financial reports. Learn how Xero financial reports can help.

The working capital formula

A working capital formula example

A retail florist calculates their working capital:

1. Add up current assets: Cash, inventory, and receivables total $100,000 over the next 12 months.
2. Add up current liabilities: Accounts payable, loan payments, and accrued expenses total $75,000.
3. Apply the formula: $100,000 − $75,000 = $25,000 in positive working capital.

This means the florist has $25,000 available after covering all short-term obligations.

Once you understand standard working capital, you may want to explore a related metric.

What is net working capital?

Net working capital measures how efficiently your business handles daily operations. Unlike standard working capital, it excludes cash and debt from the calculation.

Key differences:

• Standard working capital: includes all current assets and liabilities
• Net working capital: excludes cash (asset) and debt (liability) to focus on operational efficiency

Net working capital is useful for:

• Long-term planning: assessing operational health over time
• Expanding businesses: understanding efficiency as you grow
• Low-margin industries: retail, manufacturing, and distribution where efficiency drives profitability

The net working capital formula

Look again at the florist example. Suppose their current assets include a cash amount of $20,000, and their current liabilities include loan debts of $10,000. The new formula for their net working capital is $80,000 ($100,000 – $20,000) – $65,000 ($75,000 – $10,000) = $15,000.

Understanding the working capital ratio

The working capital ratio (also called the current ratio) measures your ability to pay short-term debts. Unlike working capital, which gives you a dollar amount, the ratio shows the relationship between your assets and liabilities as a number.

Formula: current assets ÷ current liabilities = working capital ratio

How to interpret your ratio:

• Below 1.0: you need more assets to cover short-term debts
• 1.2 to 2.0: generally considered healthy for most small businesses, with some sources considering a ratio of 1.5 to 2.0 a normal and acceptable value.
• Above 2.0: you have strong liquidity, but may not be reinvesting enough

For example, if your current assets are $100,000 and current liabilities are $75,000, your ratio is 1.33 ($100,000 ÷ $75,000). This suggests you can comfortably cover your obligations.

Working capital examples in different businesses

Different industries have different operating cycles, cash flow patterns, and asset and liability structures. This means a 'good' working capital figure varies by industry. For instance, utilities tend to have higher current ratios than technology companies.

The following examples show how working capital works in different businesses.

Working capital in construction and manufacturing

Construction and manufacturing businesses often face irregular cash flow. Long project timelines mean you pay for materials, subcontractors, and labour upfront but don't get paid until the project finishes.

Example: A building materials manufacturer assesses their financial position:

Step 1: Calculate current assets

• Cash: $100,000
• Accounts receivable: $200,000
• Inventory: $300,000
• Total: $600,000

Step 2: Calculate current liabilities

• Accounts payable: $150,000
• Short-term loans: $100,000
• Accrued expenses: $50,000
• Total: $300,000

Step 3: Apply the formula

$600,000 − $300,000 = $300,000 in positive working capital

This manufacturer has enough assets to cover liabilities and weather market uncertainty.

Working capital in service businesses

Service businesses like consultancies and agencies typically need less working capital than product-based businesses. Without inventory to manage, their main costs are payroll, office expenses, and project delivery.

However, service businesses often have higher accounts receivable because they invoice clients after completing work. You'll need enough working capital to cover operating costs while waiting for payments.

Working capital in retail

Retail and hospitality businesses often need more working capital because they hold significant inventory. You must buy stock in advance to meet customer demand, especially during peak seasons.

Balancing inventory and sales is critical. Too much stock ties up cash. Too little means lost sales. Healthy working capital helps you maintain the right balance.

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

Working capital and cash flow measure different things:

• Working capital: shows how much money remains after covering upcoming costs over 12 months. It includes liquid assets like inventory and receivables.
• Cash flow: tracks money moving in and out of your business day to day. It shows the cash you have on hand right now.

Both metrics matter. Working capital reveals your overall financial health. Cash flow shows whether you can pay today's bills.

This example from Xero's short-term cash flow projection shows total money in and out for the next 90 days but doesn't include all liquid assets or the full picture of business health.

How to manage your working capital

Managing your working capital keeps your business financially stable and ready for growth. Here are practical strategies to improve your position.

FAQs on working capital

Find answers to common questions about working capital.

What is a good working capital ratio for small businesses?

A good working capital ratio for most small businesses is between 1.2 and 2.0. A ratio below 1.0 suggests you need more assets to cover short-term debts.

Industry matters too. Service businesses typically need lower ratios than retailers managing significant inventory.

How can I improve working capital ratio?

Improve your working capital ratio:

1. Send invoices immediately to reduce payment turnaround time. Research shows that shortening your collection period can increase your profitability.
2. Negotiate longer payment terms with suppliers to slow your cash outflows.
3. Offer early payment discounts to encourage customers to pay sooner.
4. Cut non-essential spending to boost your available assets.

What happens if my working capital ratio is too low?

A low working capital ratio means your business needs more resources to cover short-term debts. If this continues, it could lead to insolvency. Consider speeding up receivables, negotiating better supplier terms, or seeking advice from a financial professional.

What is a working capital loan?

A working capital loan is short-term financing that helps cover day-to-day operating costs when your business needs additional cash. Consider it after exploring other improvement strategies.

Before taking on new debt, seek advice from a financial professional to explore all your options.

Is working capital the same as liquidity?

They're related but measure different things. Liquidity measures how easily you can convert assets to cash to pay upcoming costs. Working capital shows how much money remains after you've covered those costs. Both relate to short-term financial health, but they measure different things.
