What is working capital
Working capital is the money available for daily operations, showing the difference between short-term assets and liabilities. Think of it as your operational buffer, keeping the lights on between sales and payments.
Every business needs this buffer, whether a startup, manufacturer, or services firm. Without it, even profitable businesses can face cash flow problems.
Working capital vs cash flow: What is the difference
These two terms often get confused, but they measure different things. Cash flow tracks the actual movement of money in and out of your business over time.
Working capital, on the other hand, is a snapshot. It tells you where you stand right now, not over time.
A business can have strong cash flow but low short-term resources, or vice versa. Both situations require separate attention.
How to calculate working capital
The formula is straightforward and involves understanding the difference between current assets and liabilities.
What counts as current assets?
Assets convertible to cash within 12 months include:
- Cash and cash equivalents
- Accounts receivable
- Inventory
- Prepaid expenses
What counts as current liabilities?
Debts or obligations due within 12 months include:
- Accounts payable
- Short-term loans
- Accrued expenses
- Tax liabilities
Working capital formula
Once you have those figures, applying the calculation is simple:
Current assets − Current liabilities = Operational cushion
Example: AUD $500,000 − AUD $300,000 = AUD $200,000. Positive numbers mean you have enough short-term resources to cover obligations.
How to calculate the working capital ratio
The ratio gives you a more comparable metric. It's also called the current ratio:
Current assets ÷ Current liabilities = Ratio
Using the same example above: AUD $500,000 ÷ AUD $300,000 = 1.67.
A ratio above 1.0 shows you can meet obligations and compare liquidity with other businesses or track your own.
What is net working capital?
Net working capital (NWC) is often used interchangeably. Technically, it refers to the same calculation: current assets minus current liabilities.
Some finance teams use "net" to emphasise that it's a net figure after obligations. Either way, the formula and the meaning are the same. It gives a clear dollar figure for your operational cushion at any given point.
What does positive vs negative working capital mean
Positive numbers indicate assets exceed liabilities; you can meet obligations and invest in growth. Negative numbers indicate that liabilities exceed assets, signalling a potential cash crisis. Some large retailers operate with negative numbers by design, but for most, it's a warning.
What is a good working capital ratio
A ratio between 1.5 and 2.0 is generally considered healthy. It means you have enough buffer without tying up too much cash unnecessarily.
A ratio below 1.0 suggests liquidity risk. A ratio above 2.0 might indicate that cash is sitting idle instead of being deployed productively.
The right range depends on your industry. Businesses with fast inventory turnover often operate on lower ratios than those with slower sales cycles.
The cash conversion cycle explained
The cash conversion cycle (CCC) measures how long it takes to turn investments in inventory and operations into cash. It links directly to managing short-term resources.
A shorter cycle means cash comes back to you faster. A longer cycle means your money is tied up longer, which strains liquidity.
The formula is: CCC = Days Inventory Outstanding + Days Sales Outstanding − Days Payable Outstanding. Tracking your CCC helps you identify cash-flow bottlenecks.
How to improve your working capital
If your short-term resources are tighter than you'd like, there are practical ways to improve them. Small changes in how you manage receivables, payables, and inventory can make a meaningful difference. These include:
- Invoicing customers promptly and following up on overdue accounts
- Negotiating extended payment terms with suppliers
- Reducing excess inventory to free up cash
- Reviewing your pricing to protect margins
Timing matters as much as volume. Even if sales are strong, poor timing between payments and collections can squeeze your position.
Working capital financing options in Australia
Sometimes internal adjustments aren't enough. Businesses have several financing options to bridge gaps.
Invoice financing lets you access cash tied up in unpaid invoices before customers pay. Business lines of credit give you flexible access to funds when needed.
Trade finance can help if your gaps come from import/export cycles. Government-backed programmes through organisations like the Australian Business Growth Fund may also be worth exploring.
Choosing the right option depends on your CCC, growth stage, and how long gaps typically last.
