How we calculate this
This calculator answers "am I okay?" with three linked numbers: working capital (the dollars of current assets left after covering everything due within a year), the current ratio, and the quick ratio, which strips out inventory to show whether you could pay your bills without selling a single unit. Each gets a plain-English verdict against the classic liquidity benchmarks — labeled as the rules of thumb they are.
The formulas
- Current assets
- cash + accounts receivable + inventory + other current assets
- Current liabilities
- accounts payable + short-term debt (due within 12 months) + other current liabilities
- Working capital
- current assets − current liabilities
- Current ratio
- current assets ÷ current liabilities
- Quick ratio
- (current assets − inventory) ÷ current liabilitiesThe acid test: liquidity without depending on inventory selling first.
- Cash ratio
- cash ÷ current liabilitiesThe strictest view — what you could pay today, with no collections and no sales.
Worked example
- Say you hold $25,000 cash, $40,000 of receivables, and $30,000 of inventory, against $20,000 of payables, $10,000 of short-term debt, and $5,000 of other current liabilities.
- Current assets = $95,000; current liabilities = $35,000.
- Working capital = $95,000 − $35,000 = $60,000.
- Current ratio = $95,000 ÷ $35,000 = 2.71 — in the healthy 2.0–3.0 band, comfortably above the classic 2:1 benchmark.
- Quick ratio = ($95,000 − $30,000) ÷ $35,000 = 1.86 — without selling any inventory, you still cover near-term obligations almost twice over.
- Cash ratio = $25,000 ÷ $35,000 = 0.71 — cash alone covers about 71% of what is due, which is why collections matter.
Rates, benchmarks & sources
- Current-ratio bands — healthy at 2.0 or above (the classic 2:1), acceptable at 1.5, tight between 1.0 and 1.5, below 1.0 unable to cover near-term obligations — and the quick-ratio ≥ 1.0 guideline. — Industry rule of thumb (benchmarks.ts)
- Working capital, current, quick, and cash ratio formulas. — Standard accounting definitions (no external constants)

What this tool doesn’t model
- A snapshot, not a forecast — ratios on one balance-sheet date say nothing about next month's payroll timing, seasonality, or a big invoice landing the day after you measure.
- The bands are rules of thumb that vary a lot by industry: grocery and restaurants run healthy below 1.0 (they sell inventory before paying for it), while project businesses may need far more than 2.0.
- Treats all receivables as collectible and all inventory as saleable at book value; aged receivables and stale inventory overstate real liquidity.
- Says nothing about profitability — a business can be liquid and unprofitable, or profitable and illiquid; pair this with margin and cash-flow tools.
- A very high current ratio (above 3.0) is flagged as possibly idle cash, but whether that cash should be deployed is a judgment call this tool does not make.
Frequently asked questions
What is the difference between the current ratio and the quick ratio?
The current ratio counts inventory as if it were as good as cash; the quick ratio excludes it. If covering your bills depends on selling inventory first, the quick ratio is the honest number — in the worked example, liquidity drops from 2.71 to 1.86 once inventory is set aside. A wide gap between the two is itself a signal that your liquidity is tied up in stock.
Is a higher current ratio always better?
Up to a point. Below 1.0 you cannot cover near-term obligations; the classic 2:1 benchmark marks comfortable coverage. But above roughly 3.0 the tool flags "possibly idle cash" — assets sitting in the checking account or excess stock instead of earning a return. The bands are rules of thumb, so read them against your industry's normal working-capital rhythm.
My working capital is positive but I still struggle to pay bills — how?
Working capital measures amounts, not timing. $40,000 of receivables due in 60 days does not pay a $10,000 note due Friday. Look at the cash ratio (0.71 in the example — cash covers only part of what is due) and at when each asset converts to cash versus when each liability comes due. Slow-paying customers are the usual culprit; collections, deposits, or a line of credit bridge the gap.
What counts as short-term debt?
Anything due within the next 12 months: the drawn balance on a line of credit, the next 12 months of principal on term loans (the "current portion"), credit-card balances, and merchant-advance remittances. Leaving out the current portion of long-term debt is the most common mistake and makes every ratio look better than reality.
How can I improve these ratios without borrowing?
Work the conversion cycle: invoice immediately and chase receivables (turning AR into cash improves the cash ratio without changing the current ratio), trim slow-moving inventory (improves the quick ratio), and negotiate longer payment terms with suppliers so liabilities come due after cash arrives. Converting short-term debt to longer-term debt also moves it out of current liabilities — same debt, better liquidity math.
