Introduction to Financial Statement Analysis and Ratio Analysis

Updated 10 October 2026 · Fact-checked

Financial statement analysis means studying the balance sheet and statement of profit and loss to judge a firm's performance and position. Tools include ratio analysis, horizontal analysis (year-to-year change), vertical analysis (each item as a percentage of a base) and trend analysis (index against a base year). Compute, compare, then interpret.

Understand Introduction to Financial Statement Analysis

Financial statements report what happened. They do not tell you whether it was good. Financial statement analysis turns raw figures into judgements about profitability, liquidity, solvency and efficiency.

Ratio analysis expresses one figure in relation to another, such as current assets to current liabilities. A ratio is useful only when compared with something: the firm's own past, a competitor, an industry average or a set target.

Objectives of ratio analysis:
- Assess short-term liquidity and long-term solvency.
- Measure profitability and operating efficiency.
- Compare performance across years and across firms.
- Support planning, forecasting and control.

Users have different interests. Investors look at profitability and returns. Lenders look at liquidity and ability to pay interest. Suppliers look at short-term payment ability. Management looks at efficiency and control. Employees, tax authorities and regulators also use the figures.

Types of analysis by method:
- Horizontal analysis compares the same item across periods, showing absolute and percentage change.
- Vertical analysis expresses each item as a percentage of a base in the same period. The base is total assets (or total of liabilities and equity) for the balance sheet, and revenue from operations for the statement of profit and loss. The result is a common size statement.
- Trend analysis chooses a base year as 100 and shows later years as an index.

Limitations:
- Ratios depend on historical, accounting-based figures.
- Different accounting policies make firms hard to compare.
- Inflation distorts comparisons over time.
- Window dressing can make year-end figures look better.
- Ratios ignore qualitative factors such as management quality.
- A single ratio, read alone, can mislead.

Key rules to remember

Ratio
Ratio = Item A ÷ Item B (shown as a pure ratio, a percentage or times)
Always state the unit. Numerator and denominator must be logically related.
Horizontal analysis: absolute change
Change = Current year amount − Base (previous) year amount
A negative result is a decrease.
Horizontal analysis: percentage change
% change = (Current year − Previous year) ÷ Previous year × 100
The denominator is always the earlier year.
Vertical analysis (common size)
Common size % = Item ÷ Base figure × 100
Base: total assets for balance sheet items, revenue from operations for profit and loss items.
Trend index
Trend % = Year amount ÷ Base year amount × 100
Base year equals 100. Choose a normal year as base.

How to solve Introduction to Financial Statement Analysis questions

Use this method for any numerical or theory question on financial statement analysis.

  1. 1Read what is asked: type of analysis (horizontal, vertical, trend) or a theory point (objectives, users, limitations).
  2. 2Identify the statement and the correct base: previous year, base year, total assets or revenue.
  3. 3Draw a table with columns for the item, each year's amount, and the computed column (change, % or index).
  4. 4Compute every line with the same base and the same decimal places.
  5. 5Check totals: in a common size balance sheet, total assets and total liabilities plus equity must each equal 100%.
  6. 6Write two or three lines of interpretation: what rose, what fell, and the likely reason.
  7. 7For theory, give a heading, a one-line definition and numbered points with a short explanation each.

Quickest way: Base-first table method

When to use it: When a numerical question has limited time and several line items.

  1. Write the base figure at the top of the working and circle it.
  2. Compute the multiplier once: 100 ÷ base. Multiply each item by it.
  3. For trend, use 100 ÷ base year amount as the multiplier on every later year.
  4. Verify with one total check (100%), then write one interpretation line.

Common mistakes in Introduction to Financial Statement Analysis

  • Using the current year as the denominator in percentage change

    Students divide by the larger or latest figure by habit.

    Fix: Divide by the earlier (base) year amount every time.

  • Using total of the statement as base for profit and loss items

    Confusing the balance sheet rule with the profit and loss rule.

    Fix: Use revenue from operations as 100% in the statement of profit and loss.

  • Calling horizontal and vertical analysis the same thing

    Both produce percentages.

    Fix: Horizontal compares across time. Vertical compares items within one period.

  • Giving numbers without interpretation

    Students stop once the table is complete.

    Fix: Add short comments on the main movements and what they suggest.

  • Listing limitations without explanation

    Memorising keywords only.

    Fix: Write each limitation with one line on why it distorts the analysis.

Worked examples

Example 1

Revenue from operations of Sundaram Ltd was ₹8,00,000 in 2024-25 and ₹9,20,000 in 2025-26. Net profit was ₹80,000 and ₹1,15,000. Do a horizontal analysis.

Show the solution
  1. Revenue change = 9,20,000 − 8,00,000 = ₹1,20,000.
  2. Revenue % change = 1,20,000 ÷ 8,00,000 × 100 = 15%.
  3. Profit change = 1,15,000 − 80,000 = ₹35,000.
  4. Profit % change = 35,000 ÷ 80,000 × 100 = 43.75%.
  5. Interpretation: profit grew faster than revenue, so margins improved.

Answer: Revenue rose by ₹1,20,000 (15%) and net profit by ₹35,000 (43.75%); profit grew faster than sales.

Example 2

Prepare a common size statement for Kavya Ltd. Revenue from operations ₹5,00,000; cost of materials ₹2,00,000; employee cost ₹1,00,000; other expenses ₹50,000. Also, trend-index revenue if it was ₹4,00,000 in the base year 2023-24 and ₹5,00,000 in 2025-26.

Show the solution
  1. Base is revenue ₹5,00,000 = 100%.
  2. Cost of materials = 2,00,000 ÷ 5,00,000 × 100 = 40%.
  3. Employee cost = 1,00,000 ÷ 5,00,000 × 100 = 20%.
  4. Other expenses = 50,000 ÷ 5,00,000 × 100 = 10%.
  5. Profit before tax = 5,00,000 − 3,50,000 = ₹1,50,000, which is 30%.
  6. Trend index for 2025-26 = 5,00,000 ÷ 4,00,000 × 100 = 125, with 2023-24 = 100.

Answer: Materials 40%, employee cost 20%, other expenses 10%, profit before tax 30% of revenue. Revenue trend index for 2025-26 is 125.

Exam tips

  • MCQs often test the base used in vertical analysis or the denominator in percentage change. Check both before choosing.
  • Objectives, users and limitations are common 4-6 mark theory parts. Use numbered points with a one-line explanation.
  • Always show the table. Step marks are given for correct percentages even if interpretation is brief.
  • If a question mentions a base year, it is trend analysis. If it mentions two consecutive years, it is horizontal.

Introduction to Financial Statement Analysis: frequently asked questions

What is the difference between horizontal and vertical analysis?

Horizontal analysis compares the same item across different periods and shows change. Vertical analysis expresses every item as a percentage of a base figure within one period. Horizontal shows movement; vertical shows structure.

What is a common size statement?

It is a statement in which each item is shown as a percentage of a base, such as total assets or revenue. It lets you compare firms of different sizes and see how the structure changes over time.

How is trend analysis different from horizontal analysis?

Trend analysis fixes one base year at 100 and indexes all later years against it, usually over several years. Horizontal analysis normally compares each year with the one just before it.

Can ratio analysis be relied on alone?

No. Ratios rest on historical accounting figures and can be affected by accounting policies, inflation and window dressing. Use them with trends, industry comparison and qualitative information.
