Working capital
DEFINITION
Working capital is the money a business has available to cover day-to-day operations, calculated as current assets minus current liabilities. A positive figure means a company can fund short-term obligations from its own resources; a negative figure signals a need for outside financing.

Working capital is the money a business has available to cover its day-to-day operations, calculated as current assets minus current liabilities. A positive figure means a company can fund its short-term obligations from its own resources; a negative figure signals it may need outside financing to keep running.
Working capital measures the cushion between what a business owns that will turn into cash soon and what it owes in the near term. Current assets are the resources a company expects to convert to cash within a year, such as cash, accounts receivable, inventory, and prepaid expenses. Current liabilities are the obligations due within the same window, such as accounts payable, accrued expenses, short-term debt, and the portion of deferred revenue that will be recognized soon. The difference between the two is working capital, and the direction and size of that number say a lot about whether a business can pay its bills without scrambling. For a subscription business, the picture is shaped by deferred revenue from prepaid plans and by the rhythm of recurring collections, so the figure moves as billing cycles turn over.
Why working capital matters for subscription businesses
Working capital is a fast read on short-term financial health. Lenders, investors, and finance teams look at it to judge whether a company can meet its near-term commitments and still invest in growth. Too little working capital and a business risks missing payroll or supplier payments; too much can mean cash is sitting idle instead of funding expansion. For subscription businesses, prepaid annual plans bring cash in ahead of the revenue being earned, but they also create a matching deferred revenue liability, so their effect shows up in the composition and timing of working capital rather than in a one-time lift. Watching the figure over time helps a finance team spot a squeeze before it becomes a crisis.
A subscription platform such as Recurly sits upstream of the working-capital calculation rather than reporting the figure itself. Working capital is an accounting figure a business derives from its own balance sheet. Where a billing and subscription management platform helps is by making the inputs more timely and predictable: reliable recurring collections, recovery of failed payments, and clean records of billed, collected, and deferred amounts give a finance team more dependable numbers to work from when they assess their short-term position.
How to use working capital
Track working capital as a recurring part of financial reporting rather than a one-time snapshot. A few practical ways to put it to work:
Compare the figure across periods to see whether the short-term cushion is growing or shrinking.
Pair it with the timing of collections and payables to understand what is driving the change.
Separate the effect of deferred revenue from prepaid plans, since cash collected in advance can flatter the number while the revenue is still being earned.
Use it alongside cash flow reporting to confirm that a healthy figure reflects real liquidity and not just favorable timing.
How to calculate working capital
Working capital uses a single formula:
Working capital = Current assets - Current liabilities
The same two inputs also form the related liquidity ratio, the current ratio:
Current ratio = Current assets / Current liabilities
To work through it:
Total the current assets: cash, receivables, inventory, prepaid expenses, and other assets due within a year.
Total the current liabilities: payables, accrued expenses, short-term debt, and near-term deferred revenue.
Subtract current liabilities from current assets to get working capital.
Read the sign and size. A positive result is the short-term cushion available to fund operations; a negative result points to a near-term funding gap.
Worked example (illustrative figures):
Current assets: 800,000
Current liabilities: 500,000
Working capital = 800,000 - 500,000 = 300,000
The positive 300,000 is the short-term cushion the business has to fund operations from its own resources.
Working capital vs current ratio
Working capital and the current ratio are built from the same two inputs, which is why they are easy to mix up, but they answer different questions.
Working capital is current assets minus current liabilities, expressed as a currency amount. It tells you how much cushion exists in absolute terms.
The current ratio is current assets divided by current liabilities, expressed as a ratio. It tells you how many times over current assets cover current liabilities, which makes it easier to compare businesses of different sizes.
A company can have a large working capital figure and still have a thin current ratio if its liabilities are almost as big as its assets, so finance teams often read the two together.
Benefits and examples
Keeping an eye on working capital gives a finance team an early warning system and a planning tool at the same time. The benefits include:
A clearer view of whether the business can self-fund its operations or will need a credit line.
Earlier detection of a cash squeeze caused by slow collections or a bunching of payables.
A grounded input for decisions about hiring, inventory, and expansion timing.
For example, a subscription business that sells annual plans may collect a full year of fees up front. That cash raises current assets, but the matching deferred revenue raises current liabilities by the same amount, so the collection itself has no net effect on working capital at the moment of billing. The figure improves later, as the deferred revenue is recognized month by month and the liability shrinks while the cash stays on hand. This is why finance teams watch the composition of working capital and the timing of deferred revenue, not just the headline total.
Frequently asked questions
What is working capital in simple terms? Working capital is what a business has left over to run day to day after subtracting what it owes in the near term from what it owns that will soon turn into cash. It is calculated as current assets minus current liabilities. A positive number means the business can cover its short-term bills from its own resources.
How do you calculate working capital? Add up current assets, which are things like cash, accounts receivable, inventory, and prepaid expenses, then subtract current liabilities, which are obligations like accounts payable, accrued expenses, and near-term deferred revenue. The difference is your working capital.
Is negative working capital always bad? Not always. Negative working capital can signal a business that may struggle to meet short-term obligations, but some companies operate with it by design because they collect from customers before they have to pay suppliers. The right read depends on the business model and the timing of its cash in and cash out.
Why does working capital matter for subscription businesses? Subscription businesses often collect cash in advance on prepaid plans, which lands in current assets while the matching deferred revenue sits in current liabilities and is recognized over time. Because the two move together at billing, the cash-in-advance does not lift the total on its own; its effect shows up in the timing as the deferred revenue is recognized, so working capital gives a fuller view of near-term liquidity than the revenue line alone.
What is the difference between working capital and cash flow? Working capital is a snapshot of the short-term cushion on the balance sheet at a point in time. Cash flow tracks the actual movement of cash into and out of the business over a period. A business can show positive working capital and still run into a cash flow problem if its assets are not converting to cash fast enough.
