Wondering what is working capital and whether your business has enough? It is current assets minus current liabilities: what you can turn into cash within a year, less what you owe within a year.
Working capital is one piece of the wider picture covered in the business cash flow hub.
| Item | Value |
|---|---|
| Working capital formula | Current assets minus current liabilities |
| Usual time window for “current” | 12 months |
| Working capital ratio | Current assets ÷ current liabilities |
| Ratio range cited for most small businesses | 1.2 to 2.0 |
| Florist worked example result | $25,000 positive working capital |
These figures come from Xero’s April 2026 glossary entry and are echoed by OnDeck’s July 2024 guide. Figures and rules of thumb can change, so check the source before you rely on them.
What working capital means in plain terms
Working capital is the gap between what a business owns in the short term and what it owes in the short term. Corporate Finance Institute describes it as a measure of whether a company has enough liquid assets to pay bills that will be due within a year.
The word “current” simply means short-term. Xero’s glossary says current liabilities are generally obligations you must pay within 12 months, and that a business with no clear operating cycle can use 12 months as its window.
Corporate Finance Institute lists these typical current assets, meaning items that can be used up or turned into cash within a year:
- Cash and cash equivalents
- Inventory
- Accounts receivable, which is money customers still owe
- Marketable securities
The same source lists these typical current liabilities, meaning amounts due for payment within a year:
- Accounts payable, which is money owed to suppliers
- Short-term loans
- Accrued expenses
How to calculate working capital
The calculation needs only two totals, and a balance sheet normally gives you both of them.
- Add up your current assets: cash, receivables, inventory and similar items.
- Add up your current liabilities: payables, short-term loans and accrued expenses.
- Subtract the second total from the first. The result is your working capital.
Xero’s glossary walks through a retail florist whose cash, inventory and receivables total $100,000, while payables, loans and expenses total $75,000. Subtracting gives $25,000 in positive working capital, which Xero says is available for operations or reinvestment.
You can also express the same two totals as a working capital ratio, also called the current ratio, by dividing current assets by current liabilities. In the Xero florist example that is $100,000 ÷ $75,000, a ratio of 1.33, and a ratio above 1.0 means more assets than liabilities.
The simple formula is not the only version in use. Corporate Finance Institute describes two narrower variations:
- Current assets minus cash minus current liabilities, which excludes cash
- Accounts receivable plus inventory minus accounts payable, which focuses on the accounts tied to day-to-day operations
Positive, negative and “too much” working capital
Positive working capital means current assets exceed current liabilities. Corporate Finance Institute calls this a good sign of short-term financial health, because the business has enough liquid assets left to pay short-term bills and fund growth internally.
Negative working capital means the reverse. Corporate Finance Institute says a deficit may force a company to borrow more, and may lead to late payments to creditors and suppliers and a lower corporate credit rating.
Negative is not always a crisis, though. The same source names grocery stores like Walmart and fast-food chains like McDonald’s as examples of businesses that can operate this way, because they sell inventory quickly and are paid by customers within a few days.
Capital-intensive firms are the opposite case. Corporate Finance Institute says companies that make heavy equipment usually cannot raise cash quickly because they sell on a long-term payment basis, so adequate working capital matters more for them.
Having a lot is not automatically ideal either. Xero says excess working capital may mean a business is not making the most of its resources.
What is a good working capital ratio?
There is no single right answer, but two sources point to a similar band. OnDeck’s July 2024 guide says a good ratio generally falls between 1.2 and 2.0, and Xero’s April 2026 glossary suggests the same 1.2 to 2.0 range for most small businesses.
OnDeck adds a plain-language reading of the ratio:
- Between 0 and 1: cash flow problems, with not enough cash to cover future expenses
- Between 1 and 2: the business can repay all its current liabilities and still have current assets left over
- Above 2: the company may be sitting on capital instead of using it to grow
OnDeck also stresses that the ideal range can depend on the business’s industry. Treat any range as a rough reference point for comparison, not a target or a recommendation.
Why timing and late payments matter
Working capital is a snapshot, but cash moves on a calendar. Wall Street Prep notes that if an owed invoice payment is delayed beyond 30 days, an increase in working capital can be required to sustain operating activities.
That is why slow-paying customers feature so often in small-business stories. A related explainer on late payments small business owners face looks at that problem in more detail.
Access to working capital also shapes what a business can do. Bench cites a 2019 Babson study of small businesses in America, which found that a lack of access to working capital meant less investment in technology and equipment, reduced pay to employees and difficulties expanding into new markets.
Xero’s glossary lists general ideas that businesses use to improve their position: speeding up invoicing, negotiating longer payment terms with suppliers and managing inventory levels. Broader habits such as forecasting and tracking are covered in the guide to cash flow management for small business.
Some businesses also look at outside financing to bridge gaps. Costs, terms and rules vary by provider and country, and this site does not provide, arrange or broker funding.
Frequently asked questions
Is working capital the same as cash flow?
Show answer
No. Working capital is a balance-sheet measure built from current assets and current liabilities, while cash flow is about the movement of money in and out. Corporate Finance Institute links the two through the working capital cycle, which it describes as the timing of when cash comes in and out of the business.
Can a business operate with negative working capital?
Show answer
Sometimes. Corporate Finance Institute says that, depending on the type of business, companies can have negative working capital and still do well, citing fast-turnover retailers and restaurants. OnDeck adds that consistent negative working capital may lead to cash flow issues and hinder growth.
Where do the numbers come from?
Show answer
Bench says both current assets and current liabilities can be found on your balance sheet. If you do not have one, Bench suggests starting with bank balances for cash and an invoicing tool for receivables.
What does a ratio above 1 tell you?
Show answer
OnDeck says a ratio greater than 1 indicates positive working capital, while a ratio below 1 suggests negative working capital. The ratio is current assets divided by current liabilities.
