Calculate the quick ratio, or acid-test ratio, from current assets, inventory, prepaid expenses, and current liabilities, then review quick assets.
Last updated
Measure quick ratio / acid-test coverage The quick ratio removes inventory and prepaid expenses from current assets to focus on the most liquid assets available to meet near-term obligations. It is stricter than the current ratio and is often called the acid-test ratio.

Assumptions
The quick ratio is stricter than the current ratio because it excludes inventory and prepaid items that may be slower to convert into cash.

Quick ratio calculator guide: quick assets, acid-test coverage, liquidation cushion
A quick ratio calculator measures how well near-term liabilities are covered by the most liquid current assets after inventory and prepaid expenses are removed. It is often called the acid-test ratio because it asks a stricter liquidity question than the current ratio: what can the business cover without depending on stock sales or prepaid balances?
What the quick ratio is measuring
The quick ratio compares quick assets with current liabilities. Quick assets usually include cash, cash equivalents, marketable securities, and receivables, while inventory and prepaid expenses are excluded because they are less immediately available for liability coverage.
That makes the quick ratio a tougher test than the current ratio. Two companies can have the same current ratio but very different quick ratios if one relies heavily on inventory and the other holds more immediately liquid resources.
The formula and the quick-asset bridge
The first step is to calculate quick assets by subtracting inventory and prepaid expenses from current assets. The ratio then divides those quick assets by current liabilities. The calculator also reports the liquidation cushion in currency terms so you can see the surplus or shortfall directly.
That bridge matters because it shows where the strictness comes from. If inventory and prepaid balances are large, the quick ratio can fall materially below the current ratio even when the balance sheet initially looks comfortable.
Quick assets = Current assets - Inventory - Prepaid expenses
The liquid-asset base used for the acid-test calculation.
Quick ratio = Quick assets / Current liabilities
The strict near-term liquidity relationship used by the calculator.
Worked example: 1.98x quick coverage
Suppose current assets are 4.2 million, inventory is 650,000, prepaid expenses are 90,000, and current liabilities are 1.75 million. Quick assets are 3.46 million and the quick ratio is about 1.98x. The quick liquidation cushion is about 1.71 million.
That would usually read as comfortable immediate liquidity, but the true interpretation still depends on receivables quality, counterparty risk, timing of cash needs, and how much of the business normally relies on inventory conversion.
Why quick ratio results still need judgment
A strong quick ratio can still overstate liquidity if receivables are slow, disputed, or concentrated. A weaker quick ratio is not automatically a problem if the business turns inventory rapidly, has dependable supplier terms, or has committed funding capacity.
Use the ratio as a stricter liquidity screen rather than a standalone verdict. Cash collections, inventory velocity, covenant headroom, and access to external liquidity still matter before drawing firm conclusions.

Quick ratio vs current ratio
The current ratio includes all current assets, which makes it a broader measure of short-term liquidity. The quick ratio is stricter because it removes inventory and prepaid expenses, so it asks what the business could cover without waiting for stock to sell or prepaid balances to roll off.
That difference is why a company can show a healthy current ratio and still look only moderate on the quick ratio. If you want a faster acid-test view of the balance sheet, the quick ratio is usually the more cautious screen.

What counts as a good quick ratio
There is no single universal cutoff. A ratio above 1.0x usually means quick assets exceed current liabilities, while a result below 1.0x means the business may depend on inventory, collections, refinancing, or future cash inflows to stay current.
Sector matters a lot. Service businesses often run with less inventory and may maintain stronger quick ratios than retail, manufacturing, or seasonal businesses. The right benchmark is usually industry-specific rather than a fixed headline number.
Frequently asked questions
How is the quick ratio different from the current ratio?
The current ratio uses all current assets, while the quick ratio removes inventory and prepaid expenses to focus on assets that are more immediately liquid. That makes the quick ratio a stricter liquidity test.
Why are inventory and prepaid expenses excluded?
Because they are usually less immediate sources of liability coverage. Inventory may need to be sold first, and prepaid expenses generally cannot be used to pay creditors directly.
What does a quick ratio below 1.0x mean?
It means quick assets are smaller than current liabilities. That can indicate reliance on inventory conversion, refinancing, or future cash inflows to meet near-term obligations.
Does a high quick ratio guarantee safety?
No. It improves the liquidity picture, but receivables quality, cash timing, covenant restrictions, and debt maturities still matter. The ratio is one screen, not a complete risk opinion.
What is the difference between the quick ratio and current ratio?
The current ratio uses all current assets, while the quick ratio removes inventory and prepaid expenses to focus on the most liquid current assets. That makes the quick ratio more conservative.
Is the quick ratio the same as the acid-test ratio?
Yes. Acid-test ratio is another name for the quick ratio, and both terms refer to the same stricter liquidity check.
What is a good quick ratio?
It depends on the business and industry. A ratio above 1.0x is often considered a positive sign, but the right benchmark should reflect cash flow timing, receivables quality, and how much inventory the business normally carries.
Does a quick ratio below 1 always mean trouble?
Not always. It can indicate tighter liquidity, but some businesses run below 1.0x because they collect cash quickly, turn inventory fast, or have reliable access to credit.
Do receivables count in the quick ratio?
Yes, receivables are usually included because they are closer to cash than inventory or prepaid expenses. That said, slow or doubtful receivables can overstate how liquid the balance sheet really is.
Which businesses care most about the quick ratio?
Businesses where short-term liquidity matters a lot, or where inventory conversion can be slow, usually pay the most attention to it. Retail, manufacturing, and seasonal businesses often watch it closely.
