Net Working Capital Ratio Calculator
Net working capital measures a business's ability to meet its short-term obligations using short-term assets. When current assets exceed current liabilities, the business has a positive working capital cushion, meaning it can pay bills without needing to sell long-term assets or borrow. The NWC ratio normalises this figure by total assets, making it comparable across businesses of different sizes and enabling trend analysis over time. Enter your balance sheet figures to see both the dollar amount of net working capital and the ratio.
Net working capital ratio formula
Net Working Capital = Current Assets - Current Liabilities
NWC Ratio = (Current Assets - Current Liabilities) / Total Assets
Example: Current Assets $250,000, Current Liabilities $100,000, Total Assets $750,000. NWC = $150,000. NWC Ratio = $150,000 / $750,000 = 0.20.
Why working capital management matters
- Negative NWC signals potential liquidity problems: the business may struggle to pay suppliers or make payroll.
- Excessively high NWC can also be a concern: idle cash and excess inventory represent underutilised assets.
- Lenders and credit rating agencies monitor working capital trends to assess creditworthiness.
- SBA loans and bank lines of credit often require minimum working capital ratios as loan covenants.
Frequently asked questions
What is net working capital?
Net working capital (NWC) is current assets minus current liabilities. It represents the short-term funds available after settling all short-term obligations. A positive NWC means the business can cover its near-term debts.
What is the net working capital ratio?
The NWC ratio is (Current Assets - Current Liabilities) / Total Assets. It expresses net working capital as a proportion of total assets, showing how much of the asset base is tied up in short-term operations.
What is a healthy NWC ratio?
A positive ratio indicates adequate short-term liquidity. An NWC ratio between 0.10 and 0.20 is generally healthy for most industries, though capital-intensive businesses may operate with lower ratios.
What is included in current assets?
Current assets are assets expected to be converted to cash within one year: cash, marketable securities, accounts receivable, inventory, and prepaid expenses.
What is included in current liabilities?
Current liabilities are obligations due within one year: accounts payable, accrued expenses, the current portion of long-term debt, and deferred revenue due within 12 months.
