Your bank balance says $40,000. Your P&L says you turned a profit last quarter. But payroll runs Friday, your biggest customer hasn’t paid the invoice due two weeks ago, and suddenly that $40,000 doesn’t feel like enough. That gap between looking healthy on paper and having cash in hand is exactly what working capital measures, and most business owners don’t check the number until they’re already stuck in it.
This guide walks through the full working capital picture: what actually counts as a current asset or liability, how to calculate your ratio, what’s healthy for a small business, and what to do if your number is too low or too high.
What Counts as Working Capital (Beyond Cask in the Bank)
Working capital is the money left over after subtracting what your business owes in the next 12 months from what it owns or can convert to cash in that same window. The formula is current assets minus current liabilities.
A lot of owners only think about the cash in their checking account. Working capital is broader than that. It includes everything you could reasonably turn into cash within a year, and everything you owe within that same period.
Current Assets
Current Liabilities
- Cash and cash equivalents
- Accounts payable
- Accounts receivable
- Credit card balances
- Inventory
- Short-term loan payments due within 12 months
- Prepaid expenses
- Accrued payroll and payroll taxes
- Short-term investments
- Sales tax payable
Notice what’s missing from both columns: your building, your equipment, and any debt due more than 12 months out. Those belong on the balance sheet, but they don’t factor into working capital because they don’t affect your short-term liquidity.
The Working Capital Formula, with a Real Example
Add up your current assets. Subtract your current liabilities. The result is your working capital dollar amount.
Say your business has $220,000 in current assets ($60,000 cash, $110,000 in accounts receivable, $50,000 in inventory) and $140,000 in current liabilities ($70,000 accounts payable, $40,000 in short-term loan payments, $30,000 in accrued payroll). Your working capital is $80,000.
That number tells you whether you have a cushion. It doesn’t tell you how strong that cushion is relative to your size, which is where the working capital ratio comes in.
How to Calculate Your Working Capital Ratio
Divide current assets by current liabilities. Using the example above: $220,000 divided by $140,000 gives you a ratio of 1.57.
The ratio matters more than the dollar amount because it scales. A $500,000 business and a $5 million business could both have $80,000 in working capital, but that cushion means something very different at each size. The ratio puts the number in context.
| Working Capital Ratio | What It Generally Means |
|---|---|
|
Below 1.0 |
Current liabilities exceed current assets. A common warning sign of a short-term cash crunch. |
|
1.0 to 1.2 |
Assets and liabilities are close. Little room for a slow month or a late-paying customer. |
|
1.2 to 2.0 |
Generally considered a healthy range for most small businesses. Bills are covered with a cushion. |
|
Above 2.0 |
May signal idle cash, excess inventory, or slow-collecting receivables that could be put to better use. |
A ratio between 1.2 and 2.0 is generally considered a reasonable target range for most small businesses, though the right number depends on your industry and how predictable your cash flow is. A business with steady, recurring revenue can often run leaner than a business with seasonal swings or long customer payment cycles.
Not Sure Where Your Working Capital Stands?
Why a Healthy Ratio Doesn’t Guarantee You Can Make Payroll This Week
Working capital is a snapshot, not a forecast. It tells you whether your assets outweigh your liabilities over the next year. It doesn’t tell you whether the cash will actually land in your account before the day the bill is due next month.
Accounts receivable and inventory don’t convert to cash on your payroll’s schedule. If $70,000 of your $110,000 in receivables isn’t due to be collected until next month, that money doesn’t help you cover a payroll obligation this Friday, even though it counts toward a healthy ratio.
This is why a working capital ratio needs to be paired with a short-term cash flow forecast, typically looking out 4 to 13 weeks, that maps actual expected cash in and cash out by date. The ratio tells you if you’re structurally sound. The forecast tells you if you’re going to be short on a specific Tuesday.
Signs Your Working Capital Cushion is too Thin
- Your working capital ratio has dropped below 1.0, or is trending toward it.
- You’re using a business credit card to cover payroll or vendor payments, then paying it off later.
- You’ve started stretching vendor payments past their terms to preserve cash.
- You’ve transferred personal funds into the business more than once in the last few months.
- A single late-paying customer is enough to throw off your ability to cover expenses.
Signs You Have too Much Working Capital
A high ratio feels safer, but a ratio consistently above 2.0 can mean cash is sitting idle instead of funding growth. Common causes include:
- Inventory levels that are higher than what your sales actually require.
- Customer payment terms that are too generous, tying up cash in receivables longer than necessary.
- Cash sitting in a low-interest checking account instead of being reinvested or used to pay down higher-interest debt.
Excess working capital isn’t a crisis, but it is an opportunity cost. That cash could be funding a new hire, new equipment, or a marketing push instead of sitting unused.
5 Ways to Improve Working Capital Without Taking on New Debt
Moving cash between accounts doesn’t change your working capital. Real improvement comes from changing the underlying assets and liabilities.
1. Speed up accounts receivable collection
Invoice immediately instead of batching invoices at month end. Shorten payment terms where you can, and follow up on anything more than a few days past due instead of waiting for a monthly review.
2. Reduce slow-moving inventory
Run a report on inventory turnover and identify items that have been sitting for months. Discounting slow inventory to convert it to cash is often better than letting it tie up capital indefinitely.
3. Renegotiate vendor payment terms
Ask suppliers for net-45 or net-60 terms instead of net-30. This keeps cash in your business longer without changing anything about your assets.
4. Convert short-term debt into longer-term financing
Refinancing a short-term loan into a longer repayment schedule moves the obligation off your current liabilities, which improves your working capital ratio immediately. The SBA’s guide to working capital funding options outlines several paths for this, including lines of credit and SBA-backed loans.
5. Retain more profit in the business
Reducing owner distributions, even temporarily, lets more cash accumulate as a current asset. This is often the fastest lever available, and the one most owners overlook because it feels like giving something up rather than fixing a problem.
Building a Working Capital Plan With a Business CFO
Calculating your ratio once is a start. Knowing what target makes sense for your specific business, and building the short-term cash flow forecast that catches timing gaps before they become a crisis, is ongoing work.
A business CFO builds that forecast alongside your bookkeeping so you’re not just reacting to a low bank balance, you’re planning around it months in advance. This ties directly into the kind of strategic cash management that keeps a growing business from outrunning its own cash.
Frequently Asked Questions
What is a good working capital ratio for a small business?
A ratio between 1.2 and 2.0 is generally considered healthy for most small businesses. Below 1.0 signals a potential cash shortfall. Above 2.0 may mean cash is sitting idle instead of being put to use.
How do you calculate working capital?
Subtract current liabilities from current assets. Current assets include cash, accounts receivable, and inventory. Current liabilities include accounts payable, short-term loan payments, and accrued payroll.
Can a business be profitable and still have negative working capital?
Yes. Profit is measured over a period of time on the income statement. Working capital is a snapshot of short-term assets versus short-term liabilities. A business can show a profit while still not having enough liquid assets to cover bills due in the next 30 to 60 days.
What's the difference between working capital and cash flow?
Working capital is a point-in-time measure of current assets minus current liabilities. Cash flow tracks the actual movement of cash in and out of the business over a period. A business needs both: working capital shows the structural cushion, cash flow shows whether money is arriving in time to cover what’s due.
How much working capital should I keep in reserve?
There’s no single number that fits every business. It depends on how seasonal your revenue is, how quickly customers pay, and how much inventory you carry. A working capital ratio in the 1.2 to 2.0 range paired with a rolling cash flow forecast is a reasonable starting point for most small businesses.
What increases working capital?
Retaining profit instead of distributing it, refinancing short-term debt into longer-term financing, and bringing in additional equity or long-term financing all increase working capital. Moving cash between accounts does not, since it doesn’t change total current assets or liabilities.
Does a business line of credit count as working capital?
An undrawn line of credit is not counted in the working capital formula itself, but it functions as a backstop. Once you draw on it, the balance becomes a current liability. Many businesses use a line of credit specifically to smooth out timing gaps in their cash flow.
Know Your Number Before You Need It
Working capital isn’t a metric for your accountant to track quietly in the background. It’s what determines whether you can take on a new opportunity, ride out a slow month, or cover payroll without scrambling.
