Current Ratio: Why the Same 1.5 Can Mean Very Different Things

Two companies can both report a current ratio of 1.5 and be in completely different shape. One might be sitting on cash it can spend tomorrow. The other might be sitting on a warehouse full of stock nobody has ordered yet. The number is identical. The story behind it isn’t. That gap is why we think this ratio deserves more than the five-second glance most investors give it while scrolling through a balance sheet.

This guide covers what the current ratio measures, how to calculate it from an annual report, what the “ideal” figure really means, and the places where it misleads. There’s a worked example with two hypothetical companies, plus a three-year trend exercise, so you can see how the same arithmetic tells very different stories.

What the current ratio measures

The current ratio is a test of short-term liquidity. It asks a blunt question: if every bill falling due within the next year landed on the desk today, does the business hold enough short-term assets to cover them? AccountingTools describes it as a measure of an organisation’s ability to pay its bills in the near term, and notes that analysts use it when deciding whether to invest in or lend to a business. Corporate Finance Institute (CFI) adds that it is also called the working capital ratio, because it compares the two halves of working capital against each other.

Lenders care about it. So do suppliers deciding how much credit to extend. For a shareholder, it is one of the first checks that a company won’t run into a cash squeeze before its long-term plans have a chance to play out.

The current ratio formula

The formula could not be simpler:

Current ratio = Current assets ÷ Current liabilities

Both figures sit on the balance sheet. Most balance sheets show them as subtotals, usually labelled “Total current assets” and “Total current liabilities”, which saves you adding up line items yourself. The result is normally written as a plain number (1.5) or as a ratio (1.5:1). Same thing.

What counts as a current asset

CFI defines current assets as resources that can be turned into cash within a year or less. The usual suspects:

• Cash and bank balances.
• Cash equivalents, meaning securities with a maturity of 90 days or less.
• Marketable securities maturing within a year.
• Receivables, net of an allowance for doubtful accounts.
• Inventory, which covers raw materials, work in progress and finished goods.
• Prepaid expenses, such as insurance premiums paid in advance.

What counts as a current liability

On the other side are obligations due within a year, again following CFI’s list:

• Trade payables owed to suppliers.
• Short-term borrowings and the part of long-term loans falling due within the year.
• Accrued expenses like taxes, salaries or interest that are owed but not yet invoiced or paid.
• Deferred revenue, money customers have paid for goods or services not yet delivered.

Notice the mix. Some current assets are almost as good as cash. Others, inventory and prepaid expenses especially, are a long way from it. The ratio treats a rupee of each the same way. Keep that in mind, because it is the root of most of the trouble later.

Is 2:1 the “right” number?

You’ll often hear that 2:1 is the textbook comfort zone, and AccountingTools does say a ratio of 2:1 is preferred, with lower readings pointing to a reduced ability to pay on time. CFI’s take is that anything above 1 suggests financial well-being, and that there is no fixed upper limit because so much depends on the industry.

Both sources then add the caveat that matters more than the rule of thumb. AccountingTools says a ratio close to the industry average is usually considered acceptable, and that comparing current ratios across industries doesn’t work because financial structures differ. Its own example: retailers often run lower ratios thanks to fast inventory turnover and steady cash inflows, while capital-intensive and manufacturing businesses need higher ratios to carry their inventory and receivables.

The top end has its own warning. CFI points out that a very high current ratio can mean the company is leaving cash idle instead of putting it to work in the business. A ratio of 4 or 5 isn’t automatically a badge of safety. Sometimes it just means management doesn’t know what to do with the money.

A current ratio is only as good as the assets inside it. A rupee of cash and a rupee of slow-moving stock count the same in the formula, but not when a supplier wants to be paid.

Worked example: two companies, one ratio

Here are two hypothetical companies. The figures are invented purely to show the arithmetic, and all amounts are in ₹ crore.

Company A: 330 ÷ 220 = 1.50. Company B: 300 ÷ 200 = 1.50. On a screener, they look identical.

Now strip out the less liquid items. Take only cash and receivables, which is the logic behind the quick ratio:

• Company A: (30 + 60) ÷ 220 = 0.41
• Company B: (180 + 90) ÷ 200 = 1.35

That changes everything. Company A can cover only about 41 paise of every rupee due in the next year without selling stock. Its comfort depends on moving ₹230 crore of inventory at the value shown in the books. Company B could pay most of its short-term bills from cash and collections alone. Go one step further and look only at cash, which is what the cash ratio does: 30 ÷ 220 = 0.14 for A against 180 ÷ 200 = 0.90 for B.

None of this makes Company A a bad business. A distributor has to hold stock. The point is that its 1.5 rests on inventory, and inventory is exactly the asset AccountingTools flags as hard to liquidate. If its products stop selling, that 1.5 is far shakier than it looks.

Reading the trend, not the snapshot

A single year’s ratio tells you little. Three to five years tell you a lot. AccountingTools gives an example of a supplier reviewing a customer over three years: current assets jump as the customer expands quickly, but payables climb too, and the supplier reads the rising payables as a sign that the customer’s ability to pay is slipping. It decides to restrict credit.

Here’s a hypothetical version of the same pattern, again in ₹ crore:

Current assets grew by ₹220 crore over two years. Current liabilities grew by ₹250 crore. The business looks bigger, and the headline growth may well be exciting, but every rupee of new short-term assets has been funded by more than a rupee of short-term obligations. When we see a slide like 2.00 to 1.62 to 1.30, the next question is always: which line on the liabilities side is doing the climbing? Payables stretching out, short-term debt piling up and customer advances growing are three very different stories.

Where the current ratio misleads

Heavy inventory

AccountingTools warns that a big inventory component can make the ratio look healthier than it is, since inventory can be hard to sell quickly. It also notes that aggressive accounting, loading too much overhead cost into inventory, can inflate that figure further. Our Company A is the textbook case.

Paying bills from a credit line

Some companies run their cash close to zero and pay bills by drawing on a bank line of credit. AccountingTools points out that their current ratio can look low even though they pay on time, because the unused credit line doesn’t appear as a current asset. The longer-term question, as it notes, is whether the company can eventually pay that credit line down.

Comparing across industries

We covered this above, but it bears repeating because screeners make it so easy to get wrong. Sorting every listed company by current ratio and picking the highest is not analysis. Compare a company with its own history and with its direct peers.

Year-end timing

The ratio is a snapshot taken on one date, the last day of the reporting period. A small bit of arithmetic shows how easily it moves. Take Company B, at 300 ÷ 200 = 1.50. If it uses ₹100 crore of cash to settle payables just before the balance sheet date, current assets fall to 200 and current liabilities to 100. The ratio becomes 2.00. Nothing about the business changed; the cash simply left a few days earlier. That’s why it helps to compare the year-end figure with any interim balance sheet the company publishes during the year.

How to use it in practice

When we look at a company’s results, the current ratio fits into a short routine rather than standing alone. If you want the wider framework, our guide on how to analyse quarterly results of a company sets out where balance sheet checks fit alongside profit and cash flow.

• Calculate the ratio for at least three years. Direction matters more than level.
• Open the current assets note. See how much is cash and receivables versus inventory and other items.
• Run the quick and cash ratios alongside it. A wide gap between the current and quick ratios means the cushion depends on stock.
• Check what is driving liabilities. Short-term debt, stretched payables and customer advances carry very different risks.
• Compare with two or three direct peers. Not with the market as a whole.
• Watch the extremes. Below 1 needs an explanation. A very high reading may mean idle cash, which CFI flags as a cost of its own.

Current ratio vs quick ratio vs cash ratio

These three are best read as a ladder. The current ratio counts all current assets. The quick ratio, which CFI lists along with the acid-test ratio as another liquidity measure, drops the less liquid items such as inventory. The cash ratio keeps only cash and near-cash. Each rung is stricter than the one before. If a company looks fine on the first rung and poor on the second, you’ve learnt something specific: its liquidity depends on selling what’s in the warehouse.

The useful question is never “is the current ratio above 2?” It’s “what would this company have left to pay its bills if the stock stopped moving for a quarter?”

Bottom line

The current ratio is quick to calculate and genuinely useful, as long as you don’t stop at the headline figure. Look at what’s inside current assets, how the ratio has moved over several years, and how it compares with close peers. In our example, two companies at an identical 1.50 turned out to be miles apart once inventory came out of the picture. That one extra step is usually where the real answer is.
