What is working capital and why is it important

Working capital refers to the difference between a company’s current assets and current liabilities. It is often viewed as a snapshot of short-term financial health because it measures whether an organization has enough resources to cover near-term obligations and fund day-to-day operations.

In simple terms, working capital helps businesses pay bills, manage inventory, cover payroll and maintain operations without relying too heavily on external financing. It also gives treasury teams insight into short-term liquidity and operational efficiency.

A business may appear profitable on paper, but if it doesn’t manage its working capital effectively, it can have cash constraints.

Strong working capital can help organizations:

• Meet short-term obligations
• Maintain liquidity
• Manage operational expenses
• Reduce reliance on short-term borrowing
• Navigate disruptions
• Create greater financial flexibility

Components of working capital

Working capital is made up of assets a company expects to convert into cash within a year, and liabilities it expects to pay during that same period. Understanding what belongs in each category helps treasury and finance teams evaluate short-term liquidity and identify where cash may be tied up, or where near-term obligations could create pressure.

Current assets may include:

• Cash and cash equivalents
• Accounts receivable
• Inventory
• Short-term investments
• Prepaid expenses

Current liabilities may include:

• Accounts payable
• Short-term debt
• Accrued expenses
• Taxes payable

Working capital formula

The basic formula for calculating working capital is:

Working Capital = Current Assets – Current Liabilities

A positive number generally indicates a company has enough short-term assets to cover its short-term obligations. A negative number may signal liquidity challenges — though some industries intentionally operate with negative working capital models.

To calculate working capital:

1. Add all current assets
2. Add all current liabilities
3. Subtract liabilities from assets

Example:

A company has:

• $800,000 in current assets
• $500,000 in current liabilities

Working capital = $800,000 - $500,000

Working capital = $300,000

Another commonly used metric is the working capital ratio:

Example:

A company has:

• $800,000 in current assets
• $500,000 in current liabilities

Working capital ratio = $800,000 ÷ $500,000

Working capital ratio = 1.6

A ratio above 1 typically indicates the company can meet short-term obligations. A ratio below 1 could indicate liquidity pressure.

How working capital affects cash flow

Working capital directly influences cash flow because it affects how quickly cash moves through the business. For example:

• Slow customer payments delay incoming cash.
• Excess inventory ties up cash.
• Accelerated supplier payments reduce available liquidity.

Monitoring cash flows helps organizations identify when working capital becomes tied up in inventory or accounts receivable. This helps organizations minimize the opportunity cost of idle cash.

Common working capital challenges

Improving working capital is easier said than done. According to the 2025 AFP Treasury Benchmarking Survey, 32% of treasury professionals said improving working capital is one of their biggest challenges.

Common issues include:

• Delayed customer payments
• Excess inventory
• Supply chain disruptions
• Poor visibility into cash flows
• Rising borrowing costs
• Lack of standard payment terms or failure to follow them

Working capital strategies

Improving working capital often requires organizations to evaluate how efficiently cash moves through the business and identify areas where funds may be unnecessarily tied up. While specific strategies vary by company and industry, the goal is typically the same: Improve liquidity without disrupting operations, supplier relationships or customer experience.

Organizations may improve working capital management by:

• Accelerating collections: Improving invoicing processes, offering digital payment options and reducing overdue receivables can help bring cash into the business faster.
• Optimizing inventory levels: Reducing excess inventory can free up cash while ensuring the business can still meet customer demand.
• Managing payment timing strategically: Extending payment terms where appropriate, utilizing various payment types or improving payment scheduling can help preserve liquidity.
• Improving cash forecasting: Better forecasting helps treasury teams anticipate short-term cash needs and avoid unnecessary borrowing.
• Automating manual processes: Standardized workflows and automation tools can improve visibility, reduce errors and help organizations make faster decisions. 

Many organizations also work across treasury, finance, procurement and operations teams to identify process inefficiencies that may be limiting working capital performance, as these challenges are often operational rather than purely financial.

Determining how working capital should be financed

Organizations typically align short-term financing with short-term operational needs while balancing broader capital strategy. For example, they may use revolving credit facilities, lines of credit or other short-term borrowing options to manage temporary cash gaps caused by seasonal demand, delayed receivables or inventory fluctuations.

There are also financing options specific to each part of the cash conversion cycle, such as:

• Factoring or securitization for collections/DSO
• Special financing options for inventory, including consignment inventory/DIO
• Dynamic discounting and supply chain financing for payables/DPO

Additionally, management considers factors such as borrowing costs, debt maturity schedules, loan covenants, leverage, interest rate risk and overall liquidity needs when determining the most appropriate funding strategy. The goal is to maintain enough flexibility to support operations without taking on unnecessary financing risk.

FAQs about working capital

What is net working capital?
Net working capital is another name for working capital and primarily refers to the difference between current assets and current liabilities, though some analyses exclude certain current assets or liabilities.

What does a negative working capital mean?
Negative working capital means current liabilities exceed current assets. This may signal liquidity concerns, though some business models intentionally operate this way due to the seasonality or cyclicality of their business.

Does working capital include cash?
Yes, cash and cash equivalents are typically included as current assets.

How is working capital different from cash flow?
Working capital measures short-term financial health at a specific point in time. Cash flow tracks the movement of money in and out of a business over time.
