Comparative Financial Statements: Format and Problems

Updated 10 October 2026 · Fact-checked

Comparative financial statements place two or more periods side by side, with columns for absolute change and percentage change. Subtract the base (earlier) year from the current year, then divide that change by the base year figure and multiply by 100. Finally, interpret the major movements.

Understand Comparative Financial Statements

A single balance sheet or income statement tells you where a business stands at one point. It does not tell you whether things are getting better or worse. A comparative financial statement fixes this by showing the same items for two or more years in adjacent columns.

The usual layout has the item names on the left, then the earlier year (the base year), then the current year. Two more columns show the absolute change (in rupees) and the percentage change. Some questions also ask for a column showing the direction, such as increase or decrease.

Absolute change shows the size of the movement. Percentage change shows its relative importance. A rise of ₹2,00,000 means little for a firm with sales of ₹10 crore but a great deal for a firm with sales of ₹10 lakh.

The analysis is horizontal analysis, because you read across the years. Always use the earlier year as the base. You then read the pattern: did sales grow faster than costs, did borrowings rise faster than assets, did current liabilities outgrow current assets.

Key rules to remember

Absolute change
Absolute change = Current year figure − Base year figure
A positive result is an increase. A negative result is a decrease. Show the sign or write the word.
Percentage change
Percentage change = (Absolute change ÷ Base year figure) × 100
The base is always the earlier year. If the base year figure is zero, the percentage cannot be calculated, so write 'not defined'.
Total check
Change in total assets = Change in total equity and liabilities
In a comparative balance sheet, both sides must show the same absolute change. Use this to check your work.
Net change in a subtotal
Change in a subtotal = Sum of changes in its items
Compute subtotals from the changes or from the year totals. Both routes must agree.

How to solve Comparative Financial Statements questions

Use this layout for any comparative statement question. It works for a balance sheet and for an income statement.

  1. 1Draw columns: Particulars, previous year, current year, absolute change, percentage change.
  2. 2Copy every item for both years. Keep the order and subtotals as in the question, using Schedule III style headings where given.
  3. 3Calculate each subtotal and total for both years first, so the totals are correct before you find changes.
  4. 4For each row, find absolute change as current year minus previous year. Keep the sign.
  5. 5Divide each absolute change by the previous year figure and multiply by 100. Round to one or two decimals as the question asks.
  6. 6Check that the change in total assets equals the change in total equity and liabilities. In an income statement, check that profit changes agree with the line changes.
  7. 7Write two or three lines of interpretation. Link the main movements, such as sales growth against cost growth, and state whether they are favourable.

Quickest way: Row-by-row with a mental check

When to use it: Use this when time is short and the statement has many lines.

  1. Fill the totals of both years first and confirm the balance sheet balances.
  2. Find the absolute change for every row in one pass, down the column.
  3. Do percentages only for rows that matter first: sales, profit, total assets, borrowings. Then fill the rest.
  4. Check the total change on both sides of the balance sheet.
  5. Write the interpretation using the three biggest movements.

Common mistakes in Comparative Financial Statements

  • Using the current year as the base for percentage change

    Students divide by the larger or the latest figure out of habit.

    Fix: Always divide by the earlier year. Write 'Base = previous year' at the top of your page.

  • Dropping the sign of a decrease

    Students subtract the smaller number from the larger one to avoid negatives.

    Fix: Always calculate current minus previous. Show a negative sign or write '(decrease)'.

  • Calculating percentage change of percentages or of subtotals wrongly

    Students add up row percentages to get the subtotal percentage.

    Fix: Find the subtotal's own absolute change and divide it by the subtotal's base year figure.

  • Leaving out the interpretation

    Students treat the question as a pure calculation exercise.

    Fix: Write short comments on profitability, liquidity and financing. Marks are usually allotted for them.

  • Not checking that the balance sheet changes agree

    Students rush to the next item after each row.

    Fix: Compare the change in total assets with the change in total equity and liabilities. A mismatch points to a calculation slip.

Worked examples

Example 1

From the following, prepare a comparative income statement of Sundaram Traders Ltd. for the years ended 31 March 2025 and 31 March 2026, showing absolute and percentage change. Revenue from operations: 2025 ₹10,00,000; 2026 ₹12,50,000. Cost of goods sold: 2025 ₹6,00,000; 2026 ₹7,20,000. Operating expenses: 2025 ₹1,50,000; 2026 ₹1,80,000. Income-tax: 2025 ₹60,000; 2026 ₹90,000.

Show the solution
  1. Gross profit 2025 = 10,00,000 − 6,00,000 = ₹4,00,000. Gross profit 2026 = 12,50,000 − 7,20,000 = ₹5,30,000.
  2. Profit before tax 2025 = 4,00,000 − 1,50,000 = ₹2,50,000. Profit before tax 2026 = 5,30,000 − 1,80,000 = ₹3,50,000.
  3. Profit after tax 2025 = 2,50,000 − 60,000 = ₹1,90,000. Profit after tax 2026 = 3,50,000 − 90,000 = ₹2,60,000.
  4. Revenue: change = ₹2,50,000; % = 2,50,000 ÷ 10,00,000 × 100 = 25%.
  5. Cost of goods sold: change = ₹1,20,000; % = 1,20,000 ÷ 6,00,000 × 100 = 20%.
  6. Gross profit: change = ₹1,30,000; % = 1,30,000 ÷ 4,00,000 × 100 = 32.5%.
  7. Operating expenses: change = ₹30,000; % = 30,000 ÷ 1,50,000 × 100 = 20%.
  8. Profit before tax: change = ₹1,00,000; % = 1,00,000 ÷ 2,50,000 × 100 = 40%.
  9. Income-tax: change = ₹30,000; % = 30,000 ÷ 60,000 × 100 = 50%.
  10. Profit after tax: change = ₹70,000; % = 70,000 ÷ 1,90,000 × 100 = 36.84%.
  11. Interpretation: revenue grew 25% while cost of goods sold grew only 20%, so gross profit rose 32.5%. Operating expenses also grew slower than revenue, at 20%. Profit after tax rose 36.84%, so profitability improved. Income-tax grew fastest, at 50%, which is faster than revenue growth of 25%.

Answer: Profit after tax rose from ₹1,90,000 to ₹2,60,000, an increase of ₹70,000 or 36.84%. Cost of goods sold and operating expenses grew slower than revenue, though income-tax grew faster. Margins before tax improved.

Example 2

Prepare a comparative balance sheet of Kaveri Ltd. as at 31 March 2025 and 2026. Equity share capital: 2025 ₹8,00,000; 2026 ₹8,00,000. Reserves and surplus: 2025 ₹2,00,000; 2026 ₹3,00,000. Long-term borrowings: 2025 ₹4,00,000; 2026 ₹3,00,000. Current liabilities: 2025 ₹2,00,000; 2026 ₹3,00,000. Non-current assets: 2025 ₹11,00,000; 2026 ₹10,50,000. Current assets: 2025 ₹5,00,000; 2026 ₹6,50,000.

Show the solution
  1. Total equity and liabilities 2025 = 8,00,000 + 2,00,000 + 4,00,000 + 2,00,000 = ₹16,00,000. For 2026 = 8,00,000 + 3,00,000 + 3,00,000 + 3,00,000 = ₹17,00,000.
  2. Total assets 2025 = 11,00,000 + 5,00,000 = ₹16,00,000. For 2026 = 10,50,000 + 6,50,000 = ₹17,00,000. Both sides agree.
  3. Share capital: change ₹0; 0%.
  4. Reserves and surplus: change +₹1,00,000; 1,00,000 ÷ 2,00,000 × 100 = 50%.
  5. Long-term borrowings: change −₹1,00,000; −1,00,000 ÷ 4,00,000 × 100 = −25%.
  6. Current liabilities: change +₹1,00,000; 1,00,000 ÷ 2,00,000 × 100 = 50%.
  7. Total equity and liabilities: change +₹1,00,000; 1,00,000 ÷ 16,00,000 × 100 = 6.25%.
  8. Non-current assets: change −₹50,000; −50,000 ÷ 11,00,000 × 100 = −4.55% (rounded).
  9. Current assets: change +₹1,50,000; 1,50,000 ÷ 5,00,000 × 100 = 30%.
  10. Total assets: change +₹1,00,000; 6.25%. This matches the other side.
  11. Interpretation: working capital (current assets minus current liabilities) rose from ₹3,00,000 to ₹3,50,000. Borrowings fell by 25%, funded by retained profit, so the firm relies less on debt. Current liabilities grew 50%, faster than current assets at 30%, so liquidity needs watching.

Answer: Total assets and total equity and liabilities both rose by ₹1,00,000 (6.25%). Reserves grew 50% and borrowings fell 25%, which strengthens the capital structure, but current liabilities grew faster than current assets.

Exam tips

  • Show the base year clearly and divide by it every time. Examiners check the method, so a wrong base loses the marks for the whole column.
  • Compute totals and subtotals before the changes. Then use the balance sheet check to catch errors early.
  • Write a short interpretation even if the question only says 'prepare'. Link at least two movements, such as sales against costs.
  • In the MCQ section, expect questions that give two figures and ask for percentage change. Take care over the base year and the sign.
  • If the base year figure is zero, write 'not defined' for the percentage rather than forcing a number.

Comparative Financial Statements: frequently asked questions

What is the difference between comparative and common-size statements?

A comparative statement places different years side by side and shows the change between them. A common-size statement expresses each item as a percentage of a single total, such as sales or total assets, within one year. The first shows movement over time, the second shows structure.

Which year is the base year in a comparative statement?

The earlier year is the base. You divide the change by the earlier year figure. If a question gives three years, compare each year with the one before it unless the question says to use a fixed base.

How do I handle a decrease in the percentage column?

Calculate current minus previous, and the result will be negative. Show it with a minus sign or brackets, or write the word 'decrease' beside it. The percentage then carries the same sign.

Do I need to write comments with the statement?

Yes, in most written questions. A short note on profitability, liquidity and financing earns marks beyond the calculation. Keep it to two or three lines tied to the figures.
