What is Working Capital?
Working capital is the excess of a company’s current assets over its current liabilities — the cash buffer that keeps operations running day to day. It shows how much capital is available to pay suppliers, payroll, interest, and taxes while still investing in growth initiatives. In corporate finance, consistently positive and well-managed working capital supports stronger free cash flow, better credit terms, and higher transaction valuations.
Formula to Calculate Working Capital
Example
Imagine a company with $120,000 in current assets and $60,000 in current liabilities. Using the formula, working capital = $120,000 − $60,000 = $60,000, meaning the firm has a $60,000 liquidity cushion to cover short-term obligations and reinvest in operations. The same inputs also imply a current ratio of 2.0x, a level often viewed as a healthy liquidity position in many industries.
How to Use the Working Capital Calculator
Use your latest balance sheet, enter total current assets and current liabilities into the calculator, and it will instantly show your working capital and short-term liquidity position.
Collect your balance sheet data
- Open your most recent balance sheet and identify the totals for current assets and current liabilities (the sections usually labeled “Current Assets” and “Current Liabilities”).
Enter total current assets
- In the Current Assets field, input the total of cash, marketable securities, accounts receivable, inventory, and other assets expected to convert to cash within 12 months.
Enter total current liabilities and calculate
- In the Current Liabilities field, input the total of accounts payable, short-term debt, current portion of long-term loans, taxes payable, wages, and other short-term obligations, then hit Calculate.
Review the working capital result
- Check the output figure: a positive number means you have surplus short-term funding; a negative number flags that current liabilities exceed current assets and you may need to tighten cash management or secure financing.
Compare over time and by scenario
- Re-run the calculator with historical periods or “what-if” scenarios (e.g., faster receivables collection or lower payables) to see how changes in operations or funding would impact your working capital and liquidity.
Frequently Asked Questions
What numbers should I actually plug into “Current Assets” and “Current Liabilities” in this working capital calculator?
For Current Assets, use items that can be turned into cash within 12 months: cash and cash equivalents, marketable securities, accounts receivable, inventory, and prepaid expenses. For Current Liabilities, include obligations due within 12 months: accounts payable, short-term loans, the current portion of long-term debt, taxes payable, wages, and other accrued expenses.
How do I know if the working capital result from this calculator is “good” or “bad” for my business?
A positive result means your current assets exceed current liabilities and you have a liquidity buffer; a negative result signals potential short-term cash stress and a higher risk of missing payments. Many advisors also look at the working capital (current) ratio
, where values roughly between 1.2 and 2.0 are often viewed as healthy, though acceptable levels vary by industry and business model.
What’s the difference between the working capital number from this calculator and the working capital (current) ratio I see in reports?
This calculator gives you the absolute dollar amount of working capital, showing how much short-term funding you have left after covering near-term obligations. The working capital (current) ratio uses the same inputs but divides assets by liabilities,
, showing how many dollars of current assets back each dollar of current liabilities and making it easier to compare across time and against peers.
