Working capital
Estimates for planning only, not financial advice.
Current assets of $850K against current liabilities of $520K: working capital of $330K and a current ratio of 1.63. The verdict is adequate: $1.63 of near-term assets for every $1 of near-term bills. Below 1.2 the cushion gets thin; below 1.0 the company technically cannot cover the year's obligations.
How to Use This Calculator
Enter current assets and current liabilities from the balance sheet. The calculator returns working capital, the current ratio, and a plain-English verdict.
Enter current assets: cash, receivables, inventory expected to convert within a year.
Enter current liabilities: payables, short-term debt, accrued expenses due within a year.
Read both numbers: working capital is the dollars, the current ratio is the coverage.
The Formula
Working capital is the absolute cushion; the current ratio is the relative one. A $330K cushion means little without knowing the bills are $520K, and a 1.63 ratio means little without knowing the scale. Report both, always. "Net working capital" sometimes excludes cash and short-term debt (operating working capital); this calculator uses the standard all-in version.
Worked Example
CA $850K, CL $520K. Working capital: 850 - 520 = $330K. Current ratio: 850 / 520 = 1.6346, shown as 1.63. Verdict: adequate (1.2-2.0). If liabilities were $700K instead: working capital $150K, ratio 1.21, still adequate but tight. At $900K of liabilities: -$50K working capital, 0.94 ratio, technically insolvent short-term.
What Good Looks Like
| Current ratio | Reading |
|---|---|
| Above 2.0 | Strong; possibly over-capitalized |
| 1.2 - 2.0 | Adequate for most businesses |
| 1.0 - 1.2 | Tight; watch cash conversion |
| Below 1.0 | Negative working capital; stress |
Too high is also a signal: a ratio of 4 may mean cash hoarding or bloated inventory rather than strength. Retailers and grocers routinely run below 1.0 because suppliers fund them (payables exceed receivables); their cash conversion cycle, not the ratio, is the real test. Context from the industry and the trend beats any absolute cutoff.
Managing It
Working capital is managed in the cash conversion cycle: collect receivables faster, turn inventory faster, pay suppliers slower (without torching relationships). Each day shaved off the cycle frees cash permanently. Growth consumes working capital, which is why fast-growing profitable companies run out of cash: the calculator shows the stock, but the cycle shows the flow. For the efficiency view, our working capital turnover calculator measures how hard that $330K works.
The Cash Conversion Cycle
Working capital has a speedometer: the cash conversion cycle (CCC), the days between paying suppliers and collecting from customers. It combines three ratios: days sales outstanding (receivables / revenue x 365), days inventory outstanding (inventory / COGS x 365), minus days payable outstanding (payables / COGS x 365). A company with DSO 45, DIO 60, and DPO 30 has a CCC of 75 days: cash is tied up for two and a half months on every sale.
Each day of CCC has a dollar value: divide annual revenue by 365 and multiply by the days. For a $10 million-revenue business, one CCC day is worth about $27,400 in freed or trapped cash. Cutting DSO from 45 to 35 through tighter collections frees $274,000: real money, no new sales required. This is why CFOs obsess over receivables aging reports and inventory turns; working capital improvement is the cheapest financing a company will ever raise.
Benchmarks vary enormously by model. Grocery chains run negative CCC (customers pay cash, suppliers wait 30 days): suppliers fund the business. Software firms collect upfront and hold no inventory: structurally cash-generative. Manufacturers and distributors often sit at 60 to 120 days: every growth spurt consumes cash, which is why fast-growing distributors go broke profitably. Know your industry's normal before judging your number, then attack the longest leg of your own cycle first.
Cash Tied Up Is Opportunity Lost
Working capital is the cash your operations trap between paying and collecting. Measure it, break it into the cash conversion cycle, and attack the longest leg: faster collections, leaner inventory, smarter payables. Every day shaved off the cycle is cash back in the business, raised at zero cost. Growth consumes working capital; manage it, or growth will manage you.
Free Your Cash
Working capital optimization is the highest-ROI project most businesses never run: no new customers needed, just faster collection, leaner inventory, and smarter payment timing. Start with an aging report and an inventory review this week; the cash you free is permanent, and it funds growth without debt or dilution. Measure the cycle monthly, attack the longest leg first, and watch profitability and cash flow converge.
The discipline compounds. Companies that manage working capital tightly can grow faster on the same equity, survive downturns longer, and negotiate from strength with lenders. It is unglamorous finance, and it is where many great businesses quietly win.

Frequently Asked Questions
How do you calculate working capital?
Current assets minus current liabilities. With $850K of current assets and $520K of current liabilities: $330K. Both figures come from the balance sheet; use the same period for each. For seasonal businesses, use quarterly averages rather than a single year-end snapshot, which can flatter or condemn the number depending on the season.
What is a good current ratio?
1.2 to 2.0 is adequate for most businesses; above 2.0 is strong. Below 1.0 means negative working capital. Industry norms vary: retailers run leaner, manufacturers carry more. A ratio of 1.5 means $1.50 of short-term assets for every $1.00 of short-term obligations: comfortable coverage without obviously idle resources.
What is the difference between working capital and current ratio?
Working capital is the dollar cushion (CA minus CL); the current ratio is the coverage multiple (CA divided by CL). One is absolute, one is relative; use both together. A $10M company and a $100K company can share a 1.5 current ratio with wildly different dollar cushions; the ratio enables comparison, the dollars measure safety.
Can working capital be negative?
Yes, when current liabilities exceed current assets. It signals short-term stress for most firms, though some retailers operate this way structurally (supplier-funded). Persistent negative working capital with slowing sales is a red flag. The structural version works only while suppliers keep extending credit and sales keep flowing; when either stops, the model unwinds fast.
What is net working capital vs working capital?
Usually the same thing. Some analysts compute operating working capital excluding cash and short-term debt to isolate operations. This calculator uses the standard all-in definition. Operating working capital (receivables + inventory - payables) is the cleaner metric for DCF forecasting, since cash and debt are financing decisions rather than operational ones.
Why does growth consume working capital?
More sales need more receivables and inventory before the cash arrives. A fast-growing profitable company can run out of cash purely from working-capital growth, the classic 'profitable but broke' trap. Every 10% revenue growth at a 75-day cash conversion cycle consumes roughly 2% of annual revenue in additional working capital: growth literally eats cash before it makes it.
How do you improve working capital?
Shorten the cash conversion cycle: faster collections, leaner inventory, negotiated supplier terms. Each day removed frees cash permanently. Avoid the trap of stretching payables until suppliers revolt. Early-payment discounts (2/10 net 30) deserve analysis too: skipping them to preserve cash costs an implied 36% annualized, making them very expensive financing.
Is too much working capital bad?
It can be: excessive cash, bloated inventory, and slow collections inflate the ratio while earning nothing. A ratio of 4+ often signals lazy assets rather than strength; compare against industry norms. Activist investors target exactly this: bloated working capital is a balance sheet waiting to be raided for dividends, buybacks, or acquisitions funded by freed cash.
How does working capital relate to cash flow?
Changes in working capital drive operating cash flow: increases consume cash, decreases release it. In DCF models, forecast working-capital changes are a key line between EBITDA and free cash flow. Analysts who forecast earnings growth without forecasting the working capital to support it produce fantasy cash flows; tie the two together with a days-based assumption.
Do lenders look at working capital?
Closely. Loan covenants often require minimum current ratios or working capital levels. Deteriorating working capital is an early warning lenders watch before payment problems appear. Breaching a working-capital covenant can trigger technical default even while payments are current, giving the lender room to reprice or restrict the facility.
