A financial ratio is a division. The analysis is the sentence you write after it, and that sentence is what your points are actually for. A current ratio of 1.4 is not good news or bad news on its own — it is a number waiting for three pieces of context: what the same company did last year, what its industry does, and what kind of business it is. Supply those three and you have an argument. Skip them and you have a table.
This guide works four families of ratios — liquidity, profitability, leverage and efficiency — on figures pulled from two real annual reports filed with the SEC: Apple's fiscal 2025 Form 10-K and Walmart's fiscal 2026 Form 10-K. Every figure taken from those statements can be checked against the filing it came from. It also points you at a free federal dataset that publishes real industry benchmarks, which is the piece most guides tell you to find and never tell you where to get.
- No ratio has a target value. Apple ended fiscal 2025 with a current ratio of 0.89 and Walmart with 0.79 — both below the "safe" 1.0 you were taught, both entirely healthy.
- A benchmark is a source, not a memory. The US Census Bureau publishes current ratios by sector and by company size every quarter, free. The rows used here run from 1.17 to 2.30, and each covers a stated population — five of the eight cover only corporations with $50 million or more in assets.
- Size moves a ratio as much as sector does. All US manufacturers in the survey sat at 1.38 that quarter; those holding $5 million to $50 million in assets sat at 2.30 — same sector, same quarter.
- A blended ratio can hide two businesses. Apple's 46.9% gross margin is a mix of 36.8% on products and 75.4% on services.
- An interpretation sentence has three parts: the number, the comparison that makes it mean something, and the business reason behind the gap.
What a ratio actually tells you, and what it doesn't
Ratios exist to make companies of different sizes comparable. The US Census Bureau puts it plainly in the methodology notes to its quarterly corporate statistics: "The simplest method is to assemble related financial items, such as sales and profits, and to express this relationship in the form of a ratio." Dividing one line item by another strips out scale, so a $713 billion retailer and a $416 billion technology company can be laid side by side.
What that division cannot do is produce a verdict. The Census note continues: "Using these ratios, various aspects of corporate operations may be compared with the performance of other corporations or groups of corporations of similar size or in a similar industry." The comparison is the analysis. The ratio is only the thing being compared.
This is why an instructor writes "you have described, not analyzed" on a paper that got every calculation right. The paper reported ratios. It never compared them to anything. If you have written a results section for a research paper, the distinction is the same one you already know — reporting a finding and interpreting it are separate jobs, and only the second one earns the points.
Before you calculate anything, read the assignment's grading criteria and count how many points sit under "analysis" versus "calculation". On most finance and accounting rubrics the arithmetic is a minority of the total. If you are unsure how to read the grid, a rubric tells you exactly where the points live — and it usually says "interpretation" somewhere.
The four families, and the question each one answers
Almost every ratio you will be asked to compute belongs to one of four families. ACCA's management accounting materials group them as profitability, liquidity, activity (efficiency) and gearing — gearing being the British term for what US textbooks call leverage. You will meet both words, because a lot of the material that ranks for ratio questions is written for UK exams. If a page says "gearing", "statement of financial position" or "trade receivables", read those as leverage, balance sheet and accounts receivable.
| Family | The question it answers | Ratios you will be asked for |
|---|---|---|
| Liquidity | Can this company pay what it owes over the next year? | Current ratio; quick (acid-test) ratio; working capital |
| Profitability | How much of each sales dollar survives to the bottom line? | Gross margin; operating margin; net margin; return on assets; return on equity |
| Leverage (gearing) | Who funded the assets — lenders or owners — and can the company carry it? | Debt-to-equity; equity multiplier; interest coverage |
| Efficiency (activity) | How fast does the company turn its assets back into cash? | Inventory turnover; days inventory; receivables collection period; asset turnover |
Knowing the family matters because it tells you which comparison is legitimate. Liquidity and efficiency ratios are meaningful against the same company last year and against its own industry. Profitability ratios are meaningful across industries only as a description of the business model, never as a ranking. Comparing Walmart's net margin to Apple's and concluding Walmart is worse at business is the single most common error in a first ratio assignment.
Liquidity worked: Apple's current ratio is 0.89, and that is fine
Here are the lines you need, straight from the consolidated balance sheet in Apple's Form 10-K for the fiscal year ended September 27, 2025 (SEC accession 0000320193-25-000079). All figures are in millions of dollars.
| Balance sheet line | FY2025 (Sep 27, 2025) | FY2024 (Sep 28, 2024) |
|---|---|---|
| Total current assets | 147,957 | 152,987 |
| Inventories | 5,718 | 7,286 |
| Total current liabilities | 165,631 | 176,392 |
| Total assets | 359,241 | 364,980 |
| Total liabilities | 285,508 | 308,030 |
| Total shareholders' equity | 73,733 | 56,950 |
Current ratio = current assets ÷ current liabilities = 147,957 ÷ 165,631 = 0.89. The prior year was 152,987 ÷ 176,392 = 0.87.
Quick ratio = (current assets − inventories) ÷ current liabilities = (147,957 − 5,718) ÷ 165,631 = 0.86.
Notice how little the quick ratio moves. Stripping out every dollar of inventory costs Apple only three hundredths, because inventory is $5.7 billion of a $148 billion current-asset base. On a company where inventory is the balance sheet, the same adjustment is brutal — Walmart's current ratio of 0.79 falls to a quick ratio of 0.24 once its $58.9 billion of inventory comes out. That gap between the two ratios is itself a finding, and it is worth a sentence in your write-up.
So Apple owes more within a year than it holds in current assets, in both years shown. A student who has memorized "below 1.0 is a warning sign" now writes that Apple has a liquidity problem, and loses points for it. ACCA's own guidance says why the rule of thumb is unsafe:
"Traditionally textbooks tell us that this ratio should exceed 1:1. For a company to be able to safely meet its liabilities it should probably exceed 2:1, however, acceptable current ratios vary between industry sectors, and many companies operate safely at below the 2:1 level."
The same source makes the point most students never hear — that the direction of travel is not simply "higher is better": "With the current ratio it is not the case of the higher the better, as a very high current ratio is not necessarily good. It could indicate that a company is too liquid." Cash sitting in current assets earns nothing. A current ratio of 4.0 can mean a company is hoarding working capital it should have deployed.
What rescues Apple's 0.89 is the business behind it, and the same balance sheet shows you where to look. Apple reports $69,860m of accounts payable against $39,777m of accounts receivable — it owes suppliers considerably more than customers owe it. That gap is a funding source. Money arrives from customers before it leaves for suppliers, so the company can run a negative working-capital position without ever running short. ACCA points at the same test: "In practice a company's current ratio and quick ratio should be considered alongside the company's operating cash flow. A healthy cashflow will often compensate for weak liquidity ratios."
The number you divide has to come off the right statement. Current assets and current liabilities are balance sheet lines; revenue and net income are income statement lines. Mixing them, or using a total where the subtotal was wanted, produces a ratio that looks plausible and is wrong — and every later ratio built on the same figure inherits the error. Tying the three statements together before a single ratio is computed is the habit that prevents it, and it is where careful accounting assignment work starts.
Where to get a real industry benchmark, free
Most guides on this topic tell you to compare against your industry. Almost none tells you where the industry number comes from, so students either invent one or cite a blog that invented one. There is a first-party US source, it is free, and it updates every quarter: the Census Bureau's Quarterly Financial Report for Manufacturing, Mining, Trade, and Selected Service Industries.
The QFR surveys real corporate balance sheets and income statements and publishes the aggregates by sector and by asset size. It also publishes ratios directly — including a row labeled "Total current assets to total current liabilities", which the report defines as measuring "the ability to discharge current maturing obligations from existing current assets". Here is that row for the first quarter of 2026, from the edition issued in June 2026 (series QFR/26-Q1).
Two things fall out of that chart immediately. First, only one row on it reaches the textbook 2:1, and that row is a size band rather than an industry. Every other row sits between 1.17 and 1.46, so a company at 1.3 is not lagging a standard — it is sitting where the published figure for its sector already sits. Second, and more useful in an assignment: size moves the ratio as hard as sector does. All US manufacturing corporations in the survey sat at 1.38 that quarter. The smaller ones, holding between $5 million and $50 million in assets, sat at 2.30. Same industry, same three months, a gap of nearly a full point.
The usual explanation is that a smaller company cannot raise cash at short notice the way a large public issuer can, so it carries a bigger cushion of current assets. That kind of explanation is what turns a comparison into analysis, and it is worth saying even when you have to label it as the likely reason rather than a proven one. Sectors outside the QFR's coverage — banking, insurance, utilities — need a different source, and you should say so rather than borrowing a manufacturing benchmark that does not apply.
That size effect is also why the labels on the chart carry an asset range, and why yours should. The QFR does not survey every company in every sector: its own footnote records that the mining, wholesale trade, retail trade, information and professional services figures "represent the quarterly results of companies with total assets of $50 million and over at the time of sample selection", while manufacturing is surveyed down to $5 million. So 1.17 is not retail trade; it is large retail trade, and an all-sizes figure would sit higher if the size effect runs the same way there. Naming the population inside a benchmark, not just the sector on it, is what separates a comparison your grader can check from one they have to take on trust.
Picking the right row is part of the analysis, and you should not guess at it. Every SEC filer is assigned an industry classification on EDGAR, printed on the filing index page itself. Apple's reads SIC 3571, Electronic Computers — a manufacturing code — so its comparison row is manufacturing at 1.38, not the information sector. Walmart's classification sits on the equivalent page of its own filing; open it and read the code rather than assuming one, because that code decides which row you are entitled to compare against. Say which classification you used and why, because a reader who disagrees with your choice can then argue with the choice instead of dismissing the whole comparison.
Cite the benchmark like a source, not like common knowledge. "The sector average is around 1.2" is unsupported and a grader can see that. "US retail trade corporations with $50 million or more in total assets reported a combined current ratio of 1.17 in the first quarter of 2026 (U.S. Census Bureau, Quarterly Financial Report, QFR/26-Q1)" is a checkable claim, and it takes the same amount of space.
Profitability: the same word, two different businesses
Here are both companies' income statements side by side. Apple's figures are for the year ended September 27, 2025; Walmart's are for the year ended January 31, 2026 (SEC accession 0000104169-26-000055). Millions of dollars.
| Line | Apple FY2025 | Walmart FY2026 |
|---|---|---|
| Net sales | 416,161 | 706,413 |
| Total revenues | 416,161 | 713,163 |
| Cost of sales | 220,960 | 535,395 |
| Operating income | 133,050 | 29,825 |
| Net income attributable to the company | 112,010 | 21,893 |
Apple's net margin is 112,010 ÷ 416,161 = 26.9%. Walmart's is 21,893 ÷ 713,163 = 3.1%, using net income attributable to Walmart over total revenues. Apple keeps almost nine times as much of each sales dollar.
The wrong conclusion is that Walmart is a worse company. The right one is that these are two different machines. A retailer wins on volume and turnover; a technology company wins on margin. Walmart's 3.1% margin on $713 billion of revenue produced $21.9 billion of profit, which is not a company in trouble. The margin is low because the model is low-margin by design.
Now the part almost no guide covers. Apple's blended gross margin is 195,201 ÷ 416,161 = 46.9%. That single figure is a weighted average of two very different businesses reported in the same filing:
| Segment | Net sales | Cost of sales | Gross margin |
|---|---|---|---|
| Products | 307,003 | 194,116 | 36.8% |
| Services | 109,158 | 26,844 | 75.4% |
| Total | 416,161 | 220,960 | 46.9% |
Nobody at Apple runs a 46.9% business. The company runs a 36.8% hardware business and a 75.4% services business, and the blend is arithmetic. If your assignment asks why a company's margin moved between two years, segment mix is one of the first things to check — sometimes neither segment changed and only their weights did. Checking whether a blended ratio hides a mix is one of the fastest ways to say something the rest of the class will not.
Walmart does not report a gross profit subtotal, and its cost of sales is matched against net sales rather than total revenues. Its gross margin is therefore (706,413 − 535,395) ÷ 706,413 = 24.2%. Say which denominator you used. A grader cannot reproduce your number otherwise, and two defensible choices can differ by a full percentage point.
Efficiency and leverage: how fast the money moves, and who paid for the assets
Efficiency ratios ask how quickly a company converts assets back into cash. Inventory turnover is cost of sales divided by average inventory; days inventory is 365 divided by that.
| Measure | Apple FY2025 | Walmart FY2026 |
|---|---|---|
| Average inventory | 6,502 | 57,643 |
| Inventory turnover | 29.9× | 9.3× |
| Days inventory | 12 days | 39 days |
| Total asset turnover | 1.15 | 2.61 |
Apple clears its inventory roughly every twelve days. Walmart takes about thirty-nine — which is fast for a business holding food, apparel and general merchandise across thousands of stores. Turn it around and Walmart wins the other efficiency measure decisively: it generates $2.61 of revenue per dollar of assets against Apple's $1.15. Volume is Walmart's whole strategy, and the ratio shows it.
Apple's inventory turnover here uses product cost of sales ($194,116m) rather than total cost of sales, because inventory is physical goods and total cost of sales includes services. Using the total gives 34.0× and 11 days — a friendlier number that overstates the reality. Choose the input that matches what the ratio is measuring, then state the choice. Being visibly deliberate about an input is worth more points than a rounder answer.
Leverage asks who paid for the assets. Apple's total liabilities of $285,508m against shareholders' equity of $73,733m give a debt-to-equity ratio of 3.87 — nearly four dollars of liabilities per dollar of equity, which looks alarming until you read the equity section of the same balance sheet. Where most companies show retained earnings, Apple shows an accumulated deficit of $14,264m. That line goes negative when a company has returned more to its shareholders over time than it has retained, which is a very different situation from losing money. The denominator is small by choice, not by distress, and that distinction is the analysis.
DuPont: turning four ratios into one sentence
The DuPont decomposition is one of the most useful things you can put in a ratio assignment, because it connects three families into a single identity. Return on equity is not an independent measurement; it is the product of margin, efficiency and leverage:
Return on equity = net margin × asset turnover × equity multiplier
Run it on both companies, using average balances for the balance sheet inputs:
| Factor | Apple FY2025 | Walmart FY2026 |
|---|---|---|
| Net margin | 26.9% | 3.1% |
| × Total asset turnover | 1.15 | 2.61 |
| × Equity multiplier (avg assets ÷ avg equity) | 5.54 | 2.86 |
| = Return on equity | 171% | 23.0% |
Now the analysis writes itself, because the three factors say where each number came from: Apple earns an extraordinary margin and operates on a deliberately thin equity base, while Walmart earns almost nothing per dollar of sales and makes it up by moving assets more than twice as fast. Neither company is "better at return on equity". They arrive at their numbers by different routes, and naming the route is the whole point of the exercise.
Which denominator you pick changes the answer. Apple's return on equity is 171% on average equity and 152% on ending equity, because equity grew from $56,950m to $73,733m during the year. Neither is wrong. Pick one, use it consistently across every ratio and every year in your comparison, and say in a footnote which one you used. The same discipline applies to rounding: multiplying the three rounded factors above will land near the stated return on equity but not exactly on it, so compute from the raw figures and round only the answer.
How to write the analysis paragraph
Points are usually lost not because the table is wrong but because the prose beside it restates the table. Here is the difference, on Apple's liquidity.
Description (few points)
- "Apple's current ratio is 0.89, down from a benchmark of 2.0. The quick ratio is 0.86. This indicates weak liquidity."
- Restates the number. Cites a benchmark with no source. Reaches a verdict the evidence does not support.
Analysis (the points)
- "Apple's current ratio rose slightly to 0.89 in FY2025 from 0.87 in FY2024, and its quick ratio of 0.86 shows that inventory is almost irrelevant to its liquidity position. Both figures sit well below the 1.38 combined current ratio reported for US manufacturing corporations with $5 million or more in total assets in the first quarter of 2026 (Census QFR/26-Q1; Apple files under SIC 3571, a manufacturing code). The gap reflects the business model rather than strain: Apple collects from customers before it settles with suppliers, so it funds operations from that timing difference instead of from a working-capital cushion."
- Number, then comparison, then business reason.
That structure holds for every ratio you will ever be asked to interpret.
Give the current value and the prior period in the same sentence. A ratio without a trend is half a fact. "0.89, up from 0.87" already says more than "0.89".
The company's own prior year, a named competitor's filing, or a published industry figure. Name the source in the sentence. An uncited benchmark is the fastest way to lose your grader's trust in the rest of the table.
Payment terms, inventory model, capital structure, segment mix, seasonality. This is the sentence most write-ups are missing, and it comes from reading the company's own discussion in the 10-K rather than from the ratio.
"This would concern me if operating cash flow turned negative" shows you understand the limits of the measure. Specific hedging reads as judgment; vague hedging reads as evasion.
If the assignment is a full company case study rather than a set of ratios, the analysis paragraphs are the evidence layer inside a larger argument — structuring a case study paper is a separate skill worth getting right before you start writing. And when the distance between your finished table and that paragraph is wider than one evening, having a worked finance assignment prepared for you to review before you submit it is a reasonable way to see what a complete argument looks like on your own set of numbers.
What ratio analysis cannot tell you
Naming the limits of your own method is one of the cheapest ways to pick up analysis points, and it is a standard section in most finance rubrics. Four limits are worth stating.
- A ratio is a snapshot of a moving thing. Balance sheet figures are measured on one day. A retailer's inventory on January 31 looks nothing like its inventory on December 20, so a year-end liquidity ratio can flatter or punish a seasonal business.
- Accounting policy changes the number. Inventory costing, depreciation method, lease treatment and revenue recognition all shift ratios without anything changing in the business. Two honest companies can report different ratios on identical operations.
- Averages conceal. Apple's 46.9% gross margin is the clearest example in this article — it describes no actual business the company runs. The same is true of any industry average, which blends firms with different sizes and strategies.
- Ratios describe the past. They are computed from statements covering a period that has ended. They are evidence about what happened, not a forecast, and any sentence you write in the future tense needs an argument behind it that the ratio alone does not supply.
Write those limits into your conclusion rather than an appendix. A conclusion that says which of its own claims are weakest reads as competent, and it is far more persuasive than a conclusion that treats eleven ratios as eleven certainties.
