It represents the net liquid resources available to fund day-to-day operations, purchase inventory, pay suppliers, and cover payroll. To calculate working capital, subtract current liabilities from current assets. Current assets are resources that can be converted into cash within one year (like cash, accounts receivable, and inventory), while current liabilities are obligations due within one year (like accounts payable and short-term debt). A positive working capital indicates that a company can easily meet its short-term debt obligations. Conversely, negative working capital is a critical warning sign that the business may face cash flow crises, leading to insolvency even if the company is profitable. ## Evaluating Liquidity Ratios: Current, Quick, and Cash While working capital gives a dollar figure, financial analysts use liquidity ratios to compare companies of different sizes. The three primary liquidity ratios are the Current Ratio, Quick Ratio, and Cash Ratio. The Current Ratio divides current assets by current liabilities. A ratio between 1.5 and 2.0 is considered healthy. The Quick Ratio, also known as the Acid-Test Ratio, is more conservative; it excludes inventory from current assets because inventory can take months to sell. The Cash Ratio is the most conservative liquidity measure. It only compares cash and marketable securities against current liabilities. This shows if the business could pay all short-term debts instantly. These ratios are key indicators used by banks for lending approvals. ## The Cash Conversion Cycle and Days Inventory Outstanding Operating efficiency is closely tied to how quickly a business rotates its assets. Days Inventory Outstanding (DIO) measures the average number of days inventory sits on shelves before being sold. It represents the liquidity speed of inventory. DIO is calculated by dividing inventory value by the Cost of Goods Sold (COGS), then multiplying by 365. To evaluate inventory performance comprehensively, businesses combine this with an [inventory turnover calculator](/calculators/inventory-turnover-calculator). A long DIO slows down the cash conversion cycle, leaving the business cash-poor. Operational managers use these metrics alongside a [depreciation calculator](/calculators/depreciation-calculator) to manage capital assets and optimize cash reserves. ## How to Use This Calculator Enter your total current assets and current liabilities, then add cash & cash equivalents, inventory value, and annual COGS for the fuller liquidity picture. The calculator subtracts liabilities from assets for working capital in dollars, divides assets by liabilities for the current ratio, excludes inventory from assets for the quick ratio, isolates cash alone for the cash ratio, and uses inventory and COGS to estimate days inventory outstanding (DIO). ## Worked Example: $180,000 Current Assets A manufacturing firm reports $180,000 in current assets, $90,000 in current liabilities, $45,000 in cash, $60,000 in inventory, and $320,000 in annual COGS. Working capital: $180,000 − $90,000 = $90,000. Current ratio: $180,000 ÷ $90,000 = 2.0x. Quick ratio: ($180,000 − $60,000) ÷ $90,000 ≈ 1.33x. Cash ratio: $45,000 ÷ $90,000 = 0.5x. DIO: ($60,000 ÷ $320,000) × 365 ≈ 68.4 days — the company could cover half its current liabilities with cash alone, and comfortably more with all liquid assets. ## Related Calculators See the full receivables-to-payables timeline behind that DIO figure with the [cash conversion cycle calculator](/calculators/cash-conversion-cycle-calculator), and check how efficiently that inventory turns over with the [inventory turnover calculator](/calculators/inventory-turnover-calculator). ## Frequently asked questions ### What is working capital? The difference between a company's current assets and its current liabilities, representing cash available for daily operations. ### How is working capital calculated? Working Capital = Current Assets minus Current Liabilities. ### What are current assets? Assets that can be converted into cash within a year, including cash, accounts receivable, inventory, and pre-paid expenses. ### What are current liabilities? Obligations due within a year, including accounts payable, short-term debt, accrued liabilities, and taxes due. ### What is the Current Ratio? A liquidity ratio calculated by dividing current assets by current liabilities, measuring a company's ability to pay short-term debts. ### What is the Quick Ratio (Acid-Test)? A liquidity ratio that excludes inventory: (Current Assets minus Inventory) divided by Current Liabilities, offering a more conservative test. ### What is the Cash Ratio? The most conservative liquidity ratio, calculated by dividing cash and cash equivalents by current liabilities. ### What does negative working capital mean? It indicates a company has more obligations due in the next year than liquid assets, presenting a high risk of default or bankruptcy. ### How is Days Inventory Outstanding (DIO) calculated? DIO = (Inventory value divided by Cost of Goods Sold) × 365. ### What is accounts receivable? Money owed to a business by clients for products or services sold on credit. ### How does accounts payable affect working capital? Increasing accounts payable delays supplier payments, which preserves cash assets and temporarily improves the current ratio. ### What is a healthy quick ratio benchmark? A quick ratio of 1.0 or higher is generally considered healthy, indicating a business has enough highly liquid assets to cover short-term debts. ## Related concepts - **Current Assets** — Liquid resources expected to be sold, consumed, or converted to cash within 12 months. - **Quick Ratio** — The ratio of highly liquid current assets (excluding inventory) to current liabilities. - **Cash Conversion Cycle** — The timeline in days required to convert inventory purchases back into cash from sales. ## Related guides - [Break-Even Analysis: Formula, Example, and Calculator](https://dothecalculation.com/blog/business/break-even-analysis) — Calculate break-even units and revenue from fixed costs, selling price, and variable cost, then test how pricing or cost changes affect the result. ## Related calculators - [Days Sales Outstanding (DSO) Calculator](https://dothecalculation.com/calculators/days-sales-outstanding-calculator) — Calculate Days Sales Outstanding and accounts receivable turnover ratio to measure how efficiently your business collects customer payments. - [Inventory Turnover & DSI Calculator](https://dothecalculation.com/calculators/inventory-turnover-calculator) — Calculate inventory turnover ratio, days sales in inventory, and carrying costs to see how efficiently stock moves through your business. - [Debt Service Coverage Ratio (DSCR) Calculator](https://dothecalculation.com/calculators/dscr-calculator) — Calculate Debt Service Coverage Ratio and surplus cash flow to analyze your ability to repay loans and qualify for new financing. - [Depreciation Calculator](https://dothecalculation.com/calculators/depreciation-calculator) — Estimate annual and accumulated depreciation of business assets using straight-line or declining balance methods for accurate accounting. - [Retail Open-to-Buy (OTB) Planner](https://dothecalculation.com/calculators/open-to-buy-calculator) — Plan monthly inventory purchasing budgets from sales forecasts, markdowns, and inventory targets to avoid overstock and stockouts. - [SaaS Burn Rate & Runway Calculator](https://dothecalculation.com/calculators/saas-burn-rate-calculator) — Determine monthly burn rate, growth-adjusted runway, and revenue targets needed to reach break-even cash flow for your SaaS startup. --- _This calculator is for educational and business planning purposes only and does not constitute professional financial, tax, or legal advice.
