Quick Ratio Calculator
Calculate the quick ratio (acid-test ratio) — a company's ability to cover its current liabilities using only cash, marketable securities, and receivables, with inventory left out entirely. Solve for a target ratio, model how a transaction moves the quick ratio versus the current ratio, or benchmark against six industries.
Background
The quick ratio is a stricter version of the current ratio: Quick Ratio = (Cash + Marketable Securities + Accounts Receivable) ÷ Current Liabilities. By excluding inventory and other slow-to-convert assets, it answers a sharper question than the current ratio does — not just "could this company eventually cover its bills," but "could it cover them right now, without waiting to sell anything."
How to use this calculator
- Choose Quick Ratio to calculate the core ratio directly from cash, securities, and receivables, with a visual showing whether those quick assets alone clear the current-liabilities line.
- Choose Target Ratio Solver to find exactly how much to raise in quick assets, or how much debt to pay down, to hit a specific target ratio.
- Choose Transaction Impact to see how a real transaction — buying inventory, taking a loan, paying down debt — moves the quick ratio and the current ratio, sometimes very differently.
- Choose Industry Benchmark to compare a company's quick ratio against typical ranges across six different industries.
- Click Calculate to see the visual plus a full step-by-step explanation and a callout on what the result actually means.
How the quick ratio works
The quick ratio measures a company's most immediate liquidity — cash, marketable securities, and receivables — against what it owes in the short term, deliberately leaving inventory out of the picture.
Inventory is excluded because turning it into cash takes time and isn't guaranteed at full value — it has to be found by a buyer, sold, and collected on, unlike cash or a receivable that's already close to becoming cash.
The quick ratio is always less than or equal to the current ratio for the same company, since the current ratio's numerator includes everything the quick ratio's numerator does, plus inventory and other slower assets.
There's no single "good" quick ratio — it depends heavily on how fast a business turns over inventory. A grocery chain can run safely below 1.0x because it sells through inventory in days; a business with slow-moving inventory usually can't.
Not every transaction moves the quick ratio and current ratio the same way. Swapping cash for inventory shrinks the quick ratio while leaving the current ratio completely untouched — exactly the gap the quick ratio exists to catch.
There are exactly two ways to raise a quick ratio: increase quick assets, or reduce current liabilities. The Target Ratio Solver mode lets you solve for either path on its own.
Formulas & Equations Used
Quick Ratio: (Cash + Marketable Securities + Accounts Receivable) / Current Liabilities
Equivalent form: (Total Current Assets − Inventory − Other Non-Quick Assets) / Current Liabilities
Current Ratio (for comparison): Total Current Assets / Current Liabilities
Target via quick assets: New Quick Assets = Target × Current Liabilities
Target via liabilities: New Current Liabilities = Quick Assets / Target
Example Problems & Step-by-Step Solutions
Example 1 — The core calculation
Cash \)500,000, Securities \$200,000, AR \$300,000, Current Liabilities \$600,000.
Step: Quick Assets = 500,000 + 200,000 + 300,000 = \$1,000,000. Quick Ratio = 1,000,000 / 600,000 = 1.67x.
Result: A quick ratio of 1.67x — this company could cover its current liabilities 1.67 times over without selling any inventory.
Example 2 — Solving for a target
Quick Assets \$400,000, Current Liabilities \$600,000, target 1.0x, raising quick assets.
Step: Required Quick Assets = 1.0 × 600,000 = \(600,000. Needed increase = 600,000 − 400,000 = \)200,000.
Result: Raising \$200,000 more in quick assets brings the ratio from 0.67x to exactly 1.0x.
Example 3 — Buying inventory with cash
Cash \$200,000, AR \$150,000, Inventory \$300,000, Other CA \$50,000, CL \$500,000, buying \$150,000 of inventory with cash.
Step: Before: Quick Ratio = 350,000/500,000 = 0.70x, Current Ratio = 700,000/500,000 = 1.40x. After: Quick Assets fall to \(200,000 (Quick Ratio = 0.40x); total current assets stay at \)700,000 (Current Ratio stays 1.40x).
Result: The quick ratio drops from 0.70x to 0.40x while the current ratio doesn't move at all — the exact gap the quick ratio is built to catch.
Example 4 — A grocery chain's "low" ratio is normal
Cash \$80,000, AR \$40,000, Inventory \$900,000, Other CA \$30,000, Current Liabilities \$400,000.
Step: Quick Assets = 80,000 + 0 + 40,000 = \$120,000. Quick Ratio = 120,000 / 400,000 = 0.30x — exactly the typical figure for grocery/retail.
Result: A 0.30x quick ratio looks alarming in isolation, but it's right in line with an industry that turns over inventory in days rather than months.
Example 5 — A transaction with no effect
Collecting \$50,000 of accounts receivable in cash.
Step: Cash rises by \$50,000 and AR falls by the same \$50,000 — both are quick assets, so quick assets, current assets, and current liabilities are all unchanged.
Result: Both the quick ratio and current ratio stay exactly the same — collecting a receivable just moves value between two quick assets, it doesn't create any.
Frequently Asked Questions
Why exclude inventory specifically, and not other current assets?
Inventory is usually the least liquid, least certain current asset — it needs a buyer, a sale, and often collection afterward before it becomes cash, and there's no guarantee it sells at book value at all. Cash, securities, and receivables are already at or very near cash.
Is a higher quick ratio always better?
Not necessarily. A very high quick ratio can mean a company is sitting on excess idle cash instead of investing it in growth, inventory, or returning it to shareholders. Like most ratios, the right level depends on the business and its industry.
Why do the quick ratio and current ratio sometimes move in completely different directions?
Because the current ratio treats inventory as just as good as cash, while the quick ratio treats it as not counting at all. Any transaction that shifts value into or out of inventory (without changing total current assets) will move one ratio and leave the other untouched.
Why does paying down debt with cash sometimes make the quick ratio worse?
Subtracting the same dollar amount from both quick assets and current liabilities always pushes the ratio further from 1.0x in whichever direction it already leaned. If the ratio started below 1.0x, spending relatively scarce cash to pay down relatively larger liabilities pulls it down further — even though the debt itself has actually gone down.
Can I compare quick ratios across completely different industries?
Not directly. A grocery store's inventory turns into cash in days, so it can run a low quick ratio safely. A business with slow-moving or specialized inventory can't rely on that same speed, so it typically needs a much higher quick ratio to be equally safe. Always benchmark within the same industry.
What's the difference between the "quick assets" formula and the "subtract inventory" formula?
They're the same number reached two ways. Cash + Marketable Securities + Accounts Receivable adds up the quick assets directly; Total Current Assets − Inventory − Other Non-Quick Assets reaches the identical figure by starting from the whole and subtracting the parts that aren't quick.
