Working capital analysis

What is Working Capital?

Working capital is the amount of an entity's current assets minus its current liabilities. This represents the amount of assets that can be liquidated in the near future to pay off a firm’s more pressing obligations. A business that maintains large amounts of inventory or extends credit to its customers likely has a significant investment in working capital.

How to Use Working Capital Analysis

Working capital analysis is used to determine the liquidity and sufficiency of current assets in comparison to current liabilities. This information is needed to determine whether an organization needs additional long-term funding for its operations, or whether it should plan to shift excess cash into longer-term investment vehicles. The steps involved in working capital analysis are as follows:

  1. Examine cash outflow timing. The first part of working capital analysis is to examine the timelines within which current liabilities are due for payment. This can most easily be discerned by examining an aged accounts payable report, which divides payables into 30-day time buckets. By revising the format of this report to show smaller time buckets, it is possible to determine cash needs for much shorter time intervals. The timing of other obligations, such as accrued liabilities, can then be layered on top of this analysis to provide a detailed view of exactly when obligations must be paid.

  2. Examine cash inflow timing. Engage in the same analysis for accounts receivable, using the aged accounts receivable report, and also with short-term time buckets. The outcome of this analysis will need to be revised for those customers that have a history of paying late, so that the report reveals a more accurate assessment of probable incoming cash flows.

  3. Examine investment restrictions. A further step is to examine any investments to see if there are any restrictions on how quickly they can be sold off and converted into cash.

  4. Establish inventory conversion period. Finally, review the inventory asset in detail to estimate how long it will be before this asset can be converted into finished goods, sold, and cash received from customers. It is quite possible that the period required to convert inventory into cash will be so long that this asset is irrelevant from the perspective of being able to pay for current liabilities.

  5. Create cash forecast. The next major activity is to net these analyses together into a modified short-term cash forecast, using very brief time periods, such as intervals of every three to five days. If there is a shortage in the amount of available cash in any time bucket, it will be necessary to either plan for a delayed payment to a supplier, or to obtain sufficient cash from new debt or equity to offset the shortfall.

A working capital analysis of this type should be conducted at ongoing, regular intervals

What Causes Changes in Working Capital?

Changes in working capital occur due to fluctuations in current assets and current liabilities. Variations in business operations, as well as certain external factors, can also impact working capital. The key factors that cause these changes are as follows:

Changes in Current Assets

  • Accounts receivable. If customers take longer to pay, accounts receivable increases, reducing cash flow and working capital. Faster collections improve working capital.

  • Inventory levels. Increased inventory ties up cash, reducing working capital. Selling off excess inventory boosts cash flow.

  • Cash and cash equivalents. Higher cash reserves increase working capital, while cash outflows (for expenses or investments) reduce it.

  • Prepaid expenses. Payments made in advance (e.g., insurance, rent) decrease cash and working capital temporarily.

Changes in Current Liabilities

  • Accounts payable. Delaying supplier payments increases working capital temporarily, while paying off liabilities reduces it.

  • Short-term debt. Borrowing increases working capital, but repaying loans reduces it.

  • Accrued liabilities. Expenses incurred but not yet paid (e.g., salaries, taxes) can impact working capital when they become due.

Business Operations and External Factors

  • Sales growth. Higher sales usually increase accounts receivable and inventory, affecting working capital.

  • Seasonal demand. Businesses may experience fluctuations in working capital due to seasonal inventory buildup and sales cycles.

  • Supply chain disruptions. Delays in raw materials can increase inventory costs and reduce working capital efficiency.

  • Economic conditions. Inflation, interest rates, and market demand affect cash flows, credit availability, and working capital needs.
