Working Capital Calculator

The Working Capital Calculator measures the short-term financial health of a business in two complementary ways. First it computes your net working capital — current assets minus current liabilities — along with your current ratio and quick ratio. Then it goes further than most calculators by working out your cash conversion cycle (CCC): the number of days your cash is tied up in inventory and receivables before it returns to you, shown on an animated timeline.

What Is Working Capital?

Working capital is the money a company has available to run its everyday operations. It is the buffer between what a business owns that will turn into cash within a year (current assets) and what it owes within a year (current liabilities). Healthy working capital means a company can comfortably pay its bills, suppliers, and employees while still investing in growth.

Net Working Capital Formula

Current assets include cash and cash equivalents, accounts receivable, inventory, and other assets expected to convert to cash within one year. Current liabilities include accounts payable, short-term debt, and other obligations due within one year.

Liquidity Ratios

Two ratios put your working capital in context by comparing assets to liabilities rather than subtracting them.

The quick ratio excludes inventory because inventory can be slow or hard to sell. It is a stricter test of whether a company can meet its obligations using only its most liquid assets.

What Is the Cash Conversion Cycle?

The cash conversion cycle (CCC) answers a practical question: from the moment you spend money on inventory, how many days pass before that money comes back as cash from sales? It combines three "days" metrics.

• DIO (Days Inventory Outstanding) = Inventory ÷ COGS × 365 — how long inventory sits before it sells.
• DSO (Days Sales Outstanding) = Accounts Receivable ÷ Revenue × 365 — how long customers take to pay.
• DPO (Days Payable Outstanding) = Accounts Payable ÷ COGS × 365 — how long you take to pay suppliers.

DIO and DSO together form the operating cycle. Subtracting DPO gives the CCC, because the time you delay paying suppliers is effectively free financing. A lower CCC is better.

What Is a Negative Cash Conversion Cycle?

A negative CCC means a company collects cash from customers before it has to pay suppliers. This is a powerful position: suppliers are effectively funding the company's operations at no cost. Retail and e-commerce giants such as Amazon and Dell have famously operated with negative cycles, using the float to finance rapid growth without borrowing.

Working Capital Benchmarks

Benchmarks vary widely by industry. Grocery stores run lean, fast cycles; manufacturers with long production runs carry higher inventory and longer cycles. Always compare against peers in your own sector.

Frequently Asked Questions

What is working capital?

Working capital is the money a business has available to fund its day-to-day operations. Net working capital is calculated as current assets minus current liabilities. A positive figure means short-term assets are enough to cover short-term obligations, while a negative figure can signal liquidity problems.

How do you calculate net working capital?

Net working capital equals current assets minus current liabilities. Current assets include cash, accounts receivable, inventory, and other assets expected to convert to cash within a year. Current liabilities include accounts payable, short-term debt, and other obligations due within a year.

What is the cash conversion cycle?

The cash conversion cycle (CCC) measures how many days it takes to turn money spent on inventory back into cash from sales. It equals Days Inventory Outstanding plus Days Sales Outstanding minus Days Payable Outstanding. A lower CCC is better, and a negative CCC means you collect cash from customers before paying suppliers.

What is a good current ratio?

A current ratio between 1.5 and 3.0 is generally considered healthy. Below 1.0 means current liabilities exceed current assets, which is a liquidity risk. Above 3.0 may indicate too much idle cash or inventory that could be put to more productive use.

Can the cash conversion cycle be negative?

Yes. A negative cash conversion cycle means a company collects cash from its customers before it has to pay its suppliers. Companies such as Amazon and Dell have famously run negative cycles, effectively using supplier credit to finance their growth at no cost.

How can I improve my working capital?

You can improve working capital by collecting receivables faster, reducing excess inventory, negotiating longer payment terms with suppliers, and converting idle current assets into productive use. Each of these shortens the cash conversion cycle and frees up trapped cash.
