Quick ratio

Quick ratio is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Quick ratio rather than just read about it. In short: In finance, the quick ratio, also known as the acid-test ratio, is a liquidity ratio that measures the ability of a company to use near-cash assets (or 'quick' assets) to extinguish or retire current liabilities immediately. It is the ratio between quick assets and current liabilities.

Key takeaways

  • Quick ratio belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Quick ratio to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Quick ratio from memory before moving on to harder problems.

Reference excerpt

In finance, the quick ratio, also known as the acid-test ratio, is a liquidity ratio that measures the ability of a company to use near-cash assets (or 'quick' assets) to extinguish or retire current liabilities immediately. It is the ratio between quick assets and current liabilities. A normal liquid ratio is considered to be 1:1. A company with a quick ratio of less than 1 cannot currently fully pay back its current liabilities. The quick ratio is similar to the current ratio, but it provides a more conservative assessment of the liquidity position of a firm as it excludes inventory, which it does not consider sufficiently liquid.

Formula

Quick Ratio = Quick Assets Current Liabilities {\displaystyle {\text{Quick Ratio}}={\frac {\text{Quick Assets}}{\text{Current Liabilities}}}}

Where quick assets can be defined as follows:

Quick Assets = Cash and Cash Equivalents + Marketable Securities + Accounts Receivable = Current Assets − Inventory − Prepaid Expenses {\displaystyle {\text{Quick Assets}}={\text{Cash and Cash Equivalents}}+{\text{Marketable Securities}}+{\text{Accounts Receivable}}={\text{Current Assets}}-{\text{Inventory}}-{\text{Prepaid Expenses}}}

Although the quick ratio is a test for the financial viability of a business, it does not give a complete picture of the business's health. For example, if a business has large amounts in accounts receivable due for payment after a long period, while also having larger accounts payable due for immediate payment, the quick ratio may look healthy when the business is actually about to run out of cash. In contrast, if a business has fast payment from customers, but long terms from suppliers, it may have a low quick ratio and yet be very healthy. Generally, the acid test ratio should be 1:1 or higher for a healthy company. However, this varies widely by industry. In general, the higher the ratio, the greater the company's accounting liquidity.

Worked examples

Example 1 — a first encounter with Quick ratio

Start with the simplest possible case. Write down what Quick ratio claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Quick ratio before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Quick ratio ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Quick ratio

In research
Quick ratio appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Quick ratio in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Quick ratio is common in secondary-school and first-year university syllabi. It links to neighbouring topics Financial ratios, so understanding it makes those chapters shorter.
In everyday life
Look for Quick ratio outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Quick ratio in simple terms?

In finance, the quick ratio, also known as the acid-test ratio, is a liquidity ratio that measures the ability of a company to use near-cash assets (or 'quick' assets) to extinguish or retire current liabilities immediately. It is the ratio between quick assets and current liabilities.

Why does Quick ratio matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Quick ratio?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
