The current ratio is the simplest test of financial health: Current Assets ÷ Current Liabilities. A ratio of 2.0 means the company has $2 in short-term assets for every $1 in short-term debt. Generally, above 1.5 is comfortable; below 1.0 is a red flag — the company may struggle to pay its bills.
Current assets include cash, accounts receivable, inventory, and short-term investments. Current liabilities include accounts payable, short-term debt, and accrued expenses. The ratio varies by industry — retailers often operate with lower ratios (1.0-1.2) because they convert inventory to cash quickly, while manufacturers need higher ratios (1.5-2.0).
A very high current ratio (above 3.0) is not necessarily good — it might mean the company is sitting on too much idle cash or carrying excess inventory. Efficient companies keep current ratios in the optimal zone — enough liquidity for safety, but not so much that capital sits unproductively. Analysts track this ratio over time — a declining trend signals potential liquidity trouble ahead.
