Key takeaways

• Working capital is your current assets minus current liabilities. It shows whether you have enough money to cover daily expenses and short-term debts over the next 12 months.
• A healthy working capital ratio sits between 1.2 and 2.0. Below 1.0 means you can't cover your debts, while a very high ratio suggests cash that could be put to better use.
• Shorten your working capital cycle by sending invoices promptly, negotiating longer supplier payment terms, and keeping inventory at optimal levels to avoid tying up cash.
• Track your working capital regularly with accounting software. Real-time data, automated invoicing, and cash flow forecasting help you spot shortfalls before they become problems.

What is working capital?

Working capital is the difference between your business's current assets and current liabilities, measured in dollars. It shows how much money you have available to cover day-to-day expenses and short-term debts over the next 12 months.

A positive figure means you can pay your bills and still have funds left over. A negative figure means your debts outweigh what you can quickly turn into cash.

Current assets and liabilities

Current assets are anything you can turn into cash within a year:

• Cash: Money in bank accounts and on hand
• Accounts receivable: Payments owed to you by customers
• Inventory: Stock you can sell
• Prepaid expenses: Costs paid in advance, such as insurance
• Short-term investments: Investments you can liquidate quickly
• Tax refunds: Money owed to you by the government

More about current assets

Current liabilities are amounts you must pay within a year:

• Accounts payable: Bills you owe to suppliers
• Loan payments: Principal and interest due within 12 months
• Accrued expenses: Wages, bank fees, and other costs you've incurred but not yet paid
• Deferred revenue: Payments received for goods or services you haven't delivered yet

How to calculate working capital

To calculate working capital, subtract your current liabilities from your current assets. You'll need to project both figures for the next 12 months.

If you use accounting software, you can pull this information directly from your balance sheets and financial statements. Learn about Xero financial reports.

The working capital formula

The formula is straightforward:

Working capital = current assets – current liabilities

A positive result means you have more assets than debts. A negative result means your liabilities exceed your assets.

A working capital formula example

Here's how a retail florist calculates their working capital:

1. Add up current assets: Cash, inventory, and accounts receivable total $100,000.
2. Add up current liabilities: Accounts payable, wages owed, and short-term loans total $75,000.
3. Apply the formula: $100,000 – $75,000 = $25,000 in positive working capital.

This florist has enough assets to cover their short-term debts with $25,000 left over.

Working capital examples in different businesses

A "good" working capital figure depends on your industry. In Canada, 98.2% of employer businesses are small businesses, and they employ 46.6% of the private labour force. Getting working capital right matters across virtually every sector. Here's how it works in different industries.

Working capital in construction and manufacturing

Construction and manufacturing businesses often have irregular cash flow due to long project timelines. You may need to pay for materials, subcontractors, and labour upfront. You won't recover those costs until the project is complete.

For example, a building materials manufacturer calculates their working capital:

• Current assets: Cash ($100,000) + accounts receivable ($200,000) + inventory ($300,000) = $600,000
• Current liabilities: Accounts payable ($150,000) + short-term loans ($100,000) + accrued expenses ($50,000) = $300,000
• Working capital: $600,000 – $300,000 = $300,000

With $300,000 in positive working capital, this business has enough assets to cover its liabilities and weather uncertain markets.

Working capital in service businesses

Service businesses such as consultancies and agencies don't hold inventory. They typically need less working capital than product-based industries.

However, they often have higher accounts receivable because they invoice clients after completing work. You'll still need enough working capital to cover:

• Payroll and contractor payments
• Office and operating expenses
• Project costs before client payment arrives

Working capital in retail

Retail, wholesale, and hospitality businesses often hold significant inventory and depend heavily on steady revenue. You'll need enough working capital to buy stock in advance, especially before peak seasons.

The key is to balance inventory levels with sales. Too much stock ties up cash. Too little means missed sales. Getting this balance right keeps your working capital healthy.

The importance of working capital in business

Working capital matters because it reveals whether your business can pay its bills and invest in growth. Here's what it tells you:

• Operational health: Can you cover day-to-day expenses without borrowing?
• Resilience: Can you handle slow seasons or unexpected costs?
• Growth potential: Do you have surplus funds to reinvest in the business?

Lenders and investors also use working capital to assess how financially stable you are before approving loans or funding. According to BDC's Q1 2025 Canadian Small Business Health Index, trade delinquencies of 30 days or longer continued to rise. This happened even as lower interest rates improved overall conditions. This trend underscores why lenders pay close attention to working capital.

Positive vs negative working capital

There are three working capital positions your business can be in:

• Positive working capital: Your current assets exceed your current liabilities. You can pay your bills, cover debts, and reinvest surplus funds into the business.
• Negative working capital: Your current liabilities exceed your current assets. You may struggle to meet debts without borrowing or raising funds. If this continues, your business could face financial trouble.
• Neutral working capital: Your assets and liabilities are roughly equal. This works if you're converting inventory into cash quickly, but leaves little buffer for unexpected expenses.

Very high working capital isn't always ideal either. Research from the Bank of Canada suggests that holding too many liquid assets can eventually diminish profitability.

Working capital vs working capital ratio

Working capital is a dollar amount: current assets minus current liabilities. The working capital ratio (also called the current ratio) is a proportion: current assets divided by current liabilities.

Innovation, Science and Economic Development Canada defines this ratio as a firm's ability to pay liabilities with current assets. It shows how many times over you can cover your short-term debts.

For example, if you have $100,000 in assets and $50,000 in liabilities:

• Working capital: $100,000 – $50,000 = $50,000
• Working capital ratio: $100,000 ÷ $50,000 = 2.0

The working capital cycle

The working capital cycle measures how long it takes your business to turn working capital into usable cash. It is also called the cash conversion cycle or operating cycle. A shorter cycle means faster access to the money you need to operate and grow.

Four elements drive the cycle:

• Cash: The money you start with to purchase inventory or deliver services
• Inventory: The stock or materials you buy and hold until they're sold
• Receivables: The money customers owe you after a sale (accounts receivable)
• Payables: The bills you owe to suppliers for goods or services received (accounts payable)

The cycle begins when you pay for inventory or materials. It ends when you collect payment from your customer. The longer this takes, the more cash sits tied up in the process rather than in your bank account.

To shorten your working capital cycle, focus on collecting payments faster and extending supplier terms where possible. Send invoices as soon as work is complete. Negotiate longer payment windows with your suppliers.

Keep inventory lean so you're not paying for stock that sits on shelves. Even small improvements to cycle length can free up meaningful cash for your business.

What is net working capital?

Net working capital measures operational efficiency by excluding cash and debt from the standard formula. It is also called operating working capital. It focuses purely on how well your business converts resources into revenue.

Here's how it differs from regular working capital:

• What it excludes: Cash (from assets) and debt (from liabilities)
• What it measures: How efficiently you operate daily to convert resources into revenue
• When to use it: When assessing longer-term finances, planning expansion, or working in industries with tight margins such as retail, manufacturing, and distribution

The net working capital formula

The formula removes cash from current assets and debt from current liabilities:

Net working capital = (current assets – cash) – (current liabilities – debt)

Look again at the florist example. Suppose their current assets include $20,000 in cash, and their current liabilities include $10,000 in loan debts. Their net working capital is $80,000 ($100,000 – $20,000) – $65,000 ($75,000 – $10,000) = $15,000.

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

Working capital and cash flow measure different things, and understanding both gives you a clearer picture of your finances.

• Working capital: Shows how much money remains after covering your short-term debts. It includes all current assets and liabilities, giving you a snapshot of financial health at a point in time.
• Cash flow: Shows how money moves in and out of your business over a period. It tracks actual cash on hand but doesn't include non-cash assets such as inventory or accounts receivable.

You can have positive working capital but still run into cash flow problems. For example, if most of your assets are tied up in unpaid invoices, you may not have enough cash to pay next week's bills. Monitoring both metrics helps you spot potential issues early.

How to manage your working capital

Managing your working capital well keeps cash flowing, prevents shortfalls, and frees up funds for growth. It also helps shorten your working capital cycle so you can access your money faster. Here's how to stay on top of it.

Manage your inventory

Inventory is one of the biggest drains on working capital. Keeping it under control frees up cash for other needs.

• Keep optimal stock levels: Avoid tying up cash in unsold goods or being understocked when demand spikes.
• Turn over inventory faster: Offer promotions or discounts on slow-moving stock to free up cash.
• Use inventory software: Track stock in real time, forecast demand, and automate reordering with tools such as Xero's inventory management features.

Control your expenses

Reducing unnecessary spending is one of the fastest ways to improve your working capital position.

• Review your spending: Identify where you can reduce costs without affecting quality or operations.
• Cut non-essentials: Focus spending on activities that directly help your business grow.
• Streamline processes: Use lean practices to reduce waste and improve efficiency.

Monitor your cash flow

Regular cash flow monitoring helps you anticipate problems before they affect your working capital.

• Check regularly: Review cash inflows and outflows to anticipate shortages or surpluses before they happen.
• Build a buffer: Set aside some profits as a reserve fund for lean periods.

Invest in software tools

Accounting software helps you run your business smoothly, which directly benefits your working capital. Here's how:

• Automate invoicing: Generate and send invoices automatically, track payment status, and follow up on overdue accounts without manual effort.
• Speed up payments: Send automatic reminders and offer multiple payment options to get paid faster.
• Track expenses in real time: Monitor spending as it happens so you can control costs and spot issues early.
• Access finances anywhere: Cloud-based software lets you check your financial data and respond to cash flow issues from any device.

FAQs on working capital

Here are answers to frequently asked questions about working capital.

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 don't have enough assets to cover your debts. Service businesses can often operate with lower ratios than retailers, who need more working capital to manage inventory.

How can I improve my working capital ratio?

Send invoices as soon as work is complete to reduce payment turnaround time. This shortens the collection period for accounts receivable. You can also negotiate longer payment terms with suppliers, offer early payment discounts to customers, and cut non-essential spending to keep more cash in your business.

What happens if my working capital ratio is too low?

A low working capital ratio means your business may struggle to cover short-term debts. If this continues, your business could become insolvent. Address the issue quickly by speeding up receivables, reducing expenses, or securing short-term financing.

What is a working capital loan?

A working capital loan is short-term financing that covers day-to-day operating costs when your business is struggling with cash flow. It's typically a last resort after other efforts to improve your position haven't worked. Before taking on new debt, consult a financial advisor. Explore working capital financing at the Business Development Bank of Canada.

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 money remains after you've covered those costs. Both indicate financial health, but working capital gives you a clearer picture of your buffer for growth and unexpected expenses.

What is the working capital cycle?

The working capital cycle is the time it takes your business to convert its current assets into cash. It starts when you pay for inventory or materials and ends when you collect payment from your customer. A shorter cycle means better access to cash, which helps you cover expenses and invest in growth.
