Current Ratio Calculator
Measure short-term liquidity by dividing current assets by current liabilities. Enter totals, or switch on the itemized mode to build the figures from your balance sheet and unlock the quick ratio and cash ratio. The target planner then shows exactly how much to add or repay to hit a goal.
Formula
Worked example
A firm with $150,000 in current assets and $90,000 in current liabilities has a current ratio of 150,000 ÷ 90,000 = 1.67, with $60,000 of working capital. If $50,000 of those assets is inventory, the quick ratio is (150,000 - 50,000) ÷ 90,000 = 1.11.
What the current ratio tells you
The current ratio is a liquidity measure that compares everything a company expects to turn into cash within a year against everything it owes within that same year. A ratio of 1.0 means current assets exactly equal current liabilities, so the company could just barely pay its short-term bills. A ratio above 1.0 means there is a buffer, while a ratio below 1.0 warns that the firm may have to borrow, sell long-term assets, or raise capital to meet obligations.
Totals mode versus itemized mode
If you already know your totals, totals mode is the fastest path: enter current assets and current liabilities and read the ratio. Itemized mode instead builds those totals from the individual balance sheet lines, cash and equivalents, marketable securities, accounts receivable, inventory, and other current assets on one side, and accounts payable, short-term debt, and accrued or other liabilities on the other. Because it knows which assets are inventory and which are cash, itemized mode can also report the quick ratio (which excludes inventory) and the cash ratio (cash and securities only), giving you three liquidity views from a single set of inputs.
How to read healthy bands
There is no universal target, but a range of roughly 1.5 to 3.0 is widely considered healthy for most industries. Below 1.5 the cushion is thin and a single slow month could create a cash crunch. Above 3.0 the picture can actually be a warning sign: the company may be hoarding cash, carrying too much slow-moving inventory, or failing to reinvest, all of which drag on returns. Always compare a ratio against industry peers and the firm’s own trend over several periods rather than judging a single number in isolation.
Planning to a target ratio
Turn on the target planner to set a goal, for example the 1.5 to 2.0 level many lenders look for, and the calculator solves the problem backward. It shows two routes to the same target: how much you would need to add to current assets while holding liabilities steady, or how much current debt you would need to repay while holding assets steady. Most businesses use a mix of both. This is the same reverse-solve logic a banker applies when reviewing a loan covenant, made explicit so you can see the gap in dollars rather than guessing.
Limitations and companion metrics
The current ratio treats all current assets as equally liquid, which is misleading because inventory and prepaid expenses are far harder to convert to cash than receivables or cash itself. The quick ratio (acid-test) fixes part of this by excluding inventory, and the cash ratio is stricter still, counting only cash and marketable securities. Pairing the current ratio with these stricter ratios, the cash conversion cycle, and operating cash flow gives a fuller picture of whether a business can truly meet its obligations as they fall due.
Liquidity ratio interpretation bands
| Current ratio | Interpretation |
|---|---|
| Below 1.0 | At risk |
| 1.0-1.5 | Tight |
| 1.5-3.0 | Healthy |
| Above 3.0 | Very high |
General guidance; healthy ranges vary meaningfully by industry.
Frequently asked questions
What is a good current ratio?
A current ratio between 1.5 and 3.0 is generally considered healthy, signalling that current assets comfortably cover current liabilities without large amounts of idle cash. The ideal level varies by industry, so always compare against sector peers.
What does a current ratio below 1 mean?
A current ratio below 1 means current liabilities exceed current assets, so the company cannot cover all of its short-term obligations from liquid resources alone. It may need to refinance, sell assets, or raise new capital to avoid a cash shortfall.
How is the current ratio different from the quick ratio and cash ratio?
All three measure short-term liquidity. The quick ratio excludes inventory from the numerator, and the cash ratio is stricter still, counting only cash and marketable securities. Because inventory can be slow to sell, the quick and cash ratios are tougher tests of the ability to pay bills immediately. Use the itemized mode to see all three at once.
How do I reach a target current ratio?
To raise the ratio, you can increase current assets (collect receivables faster, build cash, or convert long-term assets) or reduce current liabilities (repay short-term debt or refinance it as long-term). The target planner in this calculator shows the exact dollar gap for each route so you can plan the mix.
