Divide current assets by current liabilities to measure short-term liquidity — can the business cover what's due within a year?
Current ratio = current assets ÷ current liabilities. Above 1 means assets cover near-term obligations; 1.5–3 is a common healthy range. Very high can signal cash or inventory sitting idle. Ideal levels vary by industry. General information only.
The current ratio compares what a business owns that's cash or soon-to-be-cash (current assets) against what it owes within a year (current liabilities). Above 1 means it can cover its short-term obligations; the comfortable zone is usually 1.5 to 3, depending on the industry.
Current ratio = current assets ÷ current liabilities
The current ratio compares what the business owns that should become cash within a year against what it owes within a year. It is a snapshot taken on one date, and it carries two assumptions that are worth saying out loud. It assumes current assets convert at book value — that the receivables collect in full and the inventory sells at cost or better — and it assumes nothing about timing inside the year. A payable due on Friday against a receivable due in eighty days is a cash crisis at a ratio of 2.0. Liquidity ratios rank the shape of the balance sheet; they do not schedule it.
$120,000 of current assets ÷ $80,000 of current liabilities = 1.5 : 1, with $40,000 of working capital, and the calculator labels that “Healthy.” Now open the numerator. Suppose those assets are $40,000 cash, $35,000 receivables and $45,000 inventory. Strip the inventory out, which is what the quick or acid-test ratio does, and you get $75,000 ÷ $80,000 = 0.94 : 1. Same business, same day, and on the strict test you are 6% short of covering near-term bills with anything you do not first have to sell. A 1.5 built on cash and a 1.5 built on stock are different animals.
Three moves change the ratio without changing the business at all. Draw $20,000 on a revolving line: assets and liabilities both rise, and 140,000 ÷ 100,000 = 1.4 — the ratio falls while your cash position improves. Pay $20,000 of invoices out of that cash instead: 100,000 ÷ 60,000 = 1.67 — the ratio rises while your cash position worsens. Refinance $30,000 of short-term debt into a term loan and 120,000 ÷ 50,000 = 2.4, on a reclassification alone. Note that working capital stayed at exactly $40,000 through the first two. That is why the ratio and the dollar figure belong on the page together.
The familiar 1.5–3.0 band is a convention rather than a law, and the exceptions are not rare. Acceptable levels vary substantially by industry, and a ratio below 1.0 can be entirely sound where inventory turns into cash faster than payables come due — grocers and restaurants collect at the till and pay suppliers on thirty-day terms, so they run thin by design. Read your own sector and your own trend before you read the band. The ceiling is real too: to show 3.0 against $80,000 of liabilities you would have to carry $240,000 of current assets, $120,000 more than today, and that surplus is usually cash earning nothing or stock that is not selling. One case where the number stops being advisory is a loan covenant — then it is contractual, it is tested on a specific date, and the test date is the thing to diary.
The first is treating liquidity as solvency. A profitable business with slow-paying customers runs out of cash on a perfectly respectable ratio. The second is window dressing: the three moves above are exactly what gets done in the week before a year end, and they are equally available to whoever is reading your statements. The third is leaving stale receivables in the numerator — an invoice two hundred days old is not a current asset in any useful sense, so age the ledger and write off what is not coming. The fourth is forgetting that the current portion of long-term debt belongs in current liabilities; omit it and the ratio flatters by exactly the amount you are about to have to pay. The fifth is comparing your number to a benchmark from another industry and concluding something about your business.
One division tells you the shape; paying the bills needs the schedule. That means an aged receivables and payables listing so you can see what is due in which week, and a rolling thirteen-week cash forecast built from it. Those two together answer the question the ratio only gestures at — not “do assets cover liabilities” but “is there money in the account on the Tuesday payroll runs.” Our Small Business Bookkeeping template carries the ledger those numbers come out of.
Yes — a very high current ratio can mean cash sitting idle or inventory not selling. Liquidity is good; hoarding unproductive assets isn't.
The quick ratio excludes inventory (harder to convert to cash fast), so it's a stricter test of immediate liquidity.
