How to interpret the result
A ratio above 1 gets treated as automatically safe, and that reading misses what the ratio is built from. A retailer with a 2.0 current ratio built mostly on inventory that only sells at a discount is worse off than a service business sitting at 1.3 built almost entirely on cash and collectible receivables: the ratio itself can't tell those two balance sheets apart.
Before you rely on it
What to check
Recompute the ratio using only cash and receivables you actually expect to collect, then compare that stricter number against the full one.
The common error
Where people go wrong with current ratio calculator
Comparing current ratio across industries as if one target fits everyone. A grocery chain and a software company carry structurally different ratios by the nature of their businesses, not because one is better run.

Where the inputs come from
Current assets include cash, receivables, inventory and other assets convertible to cash within a year, and current liabilities include payables, short-term debt, accrued expenses and the portion of long-term debt due within a year. Both appear on the balance sheet. Use the same date, and consider whether receivables and inventory are worth what the books say.
When the result stops applying
The ratio counts inventory, which may be slow to sell or worth less than book value, so it can overstate liquidity. It says nothing about the timing of receipts and payments, and a business can have a good ratio and still be short of cash next week. Window dressing at the balance sheet date can distort it.
What to compare it with
Use the quick ratio and cash ratio for stricter tests, and the working capital calculator for the dollar cushion. The cash conversion cycle and inventory turnover pages explain what drives the ratio. Lenders often set a minimum current ratio in loan covenants, so know the number.

Frequently asked questions
What current ratio is healthy for a business?
About 1.5 to 2 is common for healthy firms, though it varies by industry. A ratio under 1 means current liabilities exceed current assets.
Can a current ratio be too high?
Yes. A very high ratio can mean the business holds too much cash or inventory instead of investing it, which lowers returns.
How does it differ from the quick ratio?
The current ratio includes inventory, while the quick ratio excludes it, making the quick ratio a tougher test of near-term liquidity.
