Capital Structure and Financing Decision (Class 12)

Updated 15 October 2026 · Fact-checked

Capital structure is the mix of owners' funds (equity) and borrowed funds (debt) used to finance a business. Debt is cheaper but riskier; more debt raises EPS only when return on investment exceeds the cost of debt (trading on equity). The optimal capital structure is the debt-equity mix that maximises the value of equity shares.

More debt cuts the cost of funds but raises financial risk; trading on equity lifts EPS only when RoI is greater than the cost of debt.

Understand Capital Structure and Financing Decision

Financing decision. It is about how much finance to raise from which long-term source: shareholders' funds (equity share capital, retained earnings) and borrowed funds (debentures, loans). Factors affecting it: cost, risk, floatation costs, cash flow position, fixed operating costs (high fixed operating costs → less debt), control considerations (more equity dilutes control) and state of capital market. It determines the overall cost of capital and financial risk.

Capital structure is the mix between owners' funds and borrowed funds (equity and debt). It can be expressed as Debt ÷ Equity or Debt ÷ (Debt + Equity).

Debt vs equity.

Debt is cheaper: lenders take less risk (assured interest and repayment), and interest is tax-deductible, while dividends come from after-tax profit. With a 10% interest rate and 30% tax, the after-tax cost of debt is 7%.
Debt is riskier for the business: interest and repayment are obligatory; default can force liquidation. Equity carries no such compulsion.
So more debt lowers the overall cost of funds but raises financial risk (the chance of failing to meet payment obligations).

Financial leverage = the proportion of debt in total capital (D/E or D/(D+E)).

Trading on equity is the increase in profit earned by equity shareholders due to fixed financial charges like interest. It works only when return on investment (RoI) > cost of debt (favourable leverage). If RoI < cost of debt, more debt reduces EPS (unfavourable leverage).

Worked EBIT-EPS illustration (our figures). Total funds ₹50 lakh, debt at 12%, tax 25%, shares of ₹10.

	No debt	Debt ₹20 lakh	Debt ₹30 lakh
EBIT ₹8 lakh (RoI 16%): EAT	₹6,00,000	₹4,20,000	₹3,30,000
Shares	5,00,000	3,00,000	2,00,000
EPS	₹1.20	₹1.40	₹1.65
EBIT ₹4 lakh (RoI 8%): EPS	₹0.60	₹0.40	₹0.15

At 16% RoI (above 12%), EPS rises with debt: favourable. At 8% RoI (below 12%), EPS falls: unfavourable.

Optimal capital structure. The debt-equity mix at which the value of the equity share is maximum. Beyond a point, more debt raises the cost of equity (shareholders demand more return for more risk), and the share price may fall even if EPS rises.

Fourteen factors affecting the choice of capital structure.

1. Cash flow position: must cover fixed payment obligations with a buffer.
2. Interest coverage ratio (ICR) = EBIT ÷ interest; higher ICR, more debt capacity (but it ignores repayment and cash).
3. Debt service coverage ratio (DSCR) = (PAT + depreciation + interest + non-cash expenses) ÷ (preference dividend + interest + repayment obligation); higher DSCR, more debt capacity.
4. Return on investment: higher RoI, greater ability to use trading on equity.
5. Cost of debt: cheaper borrowing allows more debt.
6. Tax rate: a higher tax rate makes debt cheaper after tax.
7. Cost of equity: more debt raises shareholders' risk and their expected return; debt can be used only up to a level.
8. Floatation costs: public issues cost more than a loan.
9. Risk consideration: total risk = business (operating) risk + financial risk; low business risk allows more debt.
10. Flexibility: keep some borrowing power for unforeseen needs.
11. Control: debt does not dilute control; a public issue of equity may expose the firm to takeover.
12. Regulatory framework: SEBI guidelines for public issues, lending norms.
13. Stock market conditions: bullish → equity; bearish → debt.
14. Capital structure of other companies: industry norms are a guide, but should not be followed blindly.

Capital Structure and Financing Decision: key facts

Capital structure (leverage): Debt ÷ Equity, or Debt ÷ (Debt + Equity); Mix of borrowed and owners' funds.
Return on investment: RoI = EBIT ÷ Total investment × 100; Compare with the interest rate.
EPS: EPS = (EBIT − Interest) × (1 − tax rate) ÷ number of equity shares; EBIT − I = EBT; EBT − tax = EAT.
After-tax cost of debt: Interest rate × (1 − tax rate); 12% at 25% tax = 9%.
Coverage ratios: ICR = EBIT ÷ Interest; DSCR = (PAT + Depreciation + Interest + Non-cash exp.) ÷ (Pref. dividend + Interest + Repayment); Higher means safer to borrow.
Trading on equity rule: 1.RoI > cost of debt
2.favourable (EPS rises with debt); RoI < cost of debt
3.unfavourable; Most-tested idea.

How to answer Capital Structure and Financing Decision questions

Capital structure appears as 1-mark items (factors, EPS, risk), 3- or 4-mark cases (identify factors, explain trading on equity) and numerical-style questions comparing EPS under different debt levels.

1For a factor case, look for cues: cash, ICR/DSCR, RoI vs interest, tax, control fears, market mood, flexibility, industry norms.
2For trading on equity, compute RoI = EBIT ÷ total funds and compare it with the interest rate first.
3For EPS tables, go line by line: EBIT − interest = EBT; − tax = EAT; ÷ shares = EPS.
4Number of shares = equity amount ÷ face value per share.
5Conclude: favourable or unfavourable leverage, and whether more debt is advisable, mentioning financial risk.

Capital Structure and Financing Decision in real life

The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.

Trading on equity

Suppose you run a stall where every ₹100 invested earns ₹16 a year. A friend offers a loan at ₹12 per ₹100. Another stall earns only ₹8 per ₹100 and is offered the same loan.

Who gains by borrowing, and why?

Try it first, then show the solutionSolution

Your stall: earns 16%, pays 12%; the extra 4% goes to you.
Other stall: earns 8%, pays 12%; it loses 4% on every borrowed rupee.

Answer: Only you gain: when return on investment (16%) exceeds the cost of debt (12%), borrowing raises the owner's return. For the other stall, borrowing at 12% to earn 8% reduces the owner's return.

Memory hook: Borrow to earn more than you pay, never less.

Control consideration

Imagine the founders of a listed snack company own 40% of its shares. A rival group has been quietly buying shares. The company needs ₹100 crore for a new plant.

Should it issue new equity shares or debentures?

Try it first, then show the solutionSolution

New equity would reduce the founders' holding below 40%.
That makes a takeover easier.
Debentures do not dilute control.

Answer: Debentures (debt), because a public issue of equity would dilute the founders' control and make the company more vulnerable to a takeover; debt does not dilute control (provided cash flows can service it).

Memory hook: Shares share control; debt doesn't.

Ordered from board level to HOTS. Try each one before you open the solution.

Example 1: Meaning of capital structure · 1 mark · MCQBoard level

Capital structure refers to the mix of:
(a) fixed and current assets
(b) owners' funds and borrowed funds
(c) cash and marketable securities
(d) long-term and short-term liabilities

Try it first, then show the solutionSolution

Capital structure is the proportion of debt and equity (1 mark).

Answer: (b) owners' funds and borrowed funds

Example 2: Factors from a case · 2 marks · Short answerBoard level

'Kavya Cement Ltd.' wants to raise ₹200 crore. Its EBIT covers interest eight times, and its promoters fear losing control if more shares are issued. Identify two factors that favour raising debt. (2 marks)

Try it first, then show the solutionSolution

'EBIT covers interest eight times': interest coverage ratio (1 mark).
'fear losing control': control (1 mark).

Answer: (1) Interest coverage ratio: a high ICR (8 times) shows low risk of failing to pay interest, so more debt can be used. (2) Control: debt does not dilute the promoters' control, whereas a new equity issue would.

Example 3: EBIT-EPS: favourable leverage · 4 marks · Short answerHarder board level

'Orion Ltd.' needs total funds of ₹50 lakh. EBIT is ₹8 lakh, interest on debt is 12% and the tax rate is 25%. Shares are of ₹10 each. Calculate EPS if (i) all funds are equity, (ii) ₹20 lakh is raised as debt. State whether trading on equity is favourable. (4 marks)

Try it first, then show the solutionSolution

(i) Interest nil; EBT ₹8,00,000; tax ₹2,00,000; EAT ₹6,00,000; shares 5,00,000; EPS = ₹1.20 (1½ marks).
(ii) Interest ₹2,40,000; EBT ₹5,60,000; tax ₹1,40,000; EAT ₹4,20,000; shares 3,00,000; EPS = ₹1.40 (1½ marks).
RoI = 8/50 = 16% > 12%: favourable (1 mark).

Answer: (i) EPS ₹1.20; (ii) EPS ₹1.40. RoI (16%) is higher than the cost of debt (12%), so using debt raises EPS: trading on equity is favourable.

Example 4: When debt hurts · 3 marks · Short answerHarder board level

In the Orion Ltd. example, suppose EBIT falls to ₹4 lakh. Calculate EPS with no debt and with ₹30 lakh of debt, and explain the result. (3 marks)

Try it first, then show the solutionSolution

No debt: EAT = 4,00,000 × 0.75 = ₹3,00,000; ÷ 5,00,000 = ₹0.60 (1 mark).
Debt ₹30 lakh: interest ₹3,60,000; EBT ₹40,000; tax ₹10,000; EAT ₹30,000; ÷ 2,00,000 = ₹0.15 (1 mark).
RoI 8% < 12%: unfavourable leverage (1 mark).

Answer: EPS falls from ₹0.60 to ₹0.15. RoI (4/50 = 8%) is below the 12% cost of debt, so every borrowed rupee costs more than it earns; this is unfavourable financial leverage, and trading on equity is not advisable.

Example 5: Why not maximum debt? · 4 marks · Short answerHOTS / competency

Suppose a director of Orion Ltd. argues, 'Since EPS rises with debt at 16% RoI, let us finance ₹45 lakh of the ₹50 lakh with debt.' Evaluate, using at least three factors affecting capital structure. (4 marks)

Try it first, then show the solutionSolution

Financial risk rises: obligatory interest of ₹5.4 lakh on EBIT of ₹8 lakh; ICR falls to about 1.5 (1 mark).
Cost of equity rises: shareholders demand more return, share price may fall despite higher EPS (1 mark).
Flexibility lost; cash flow must cover interest and repayment; EBIT may fall (2 marks).

Answer: Not advisable. (1) Risk consideration: interest at 12% on ₹45 lakh is ₹5.4 lakh against EBIT of ₹8 lakh, so ICR drops to about 1.5; a small fall in EBIT could cause default. (2) Cost of equity: higher financial risk raises shareholders' expected return, so the share price may fall even though EPS rises. (3) Flexibility: using full debt capacity leaves no borrowing power for emergencies. (4) Cash flow position must cover interest and repayment with a buffer. The optimal mix maximises share value, not EPS alone.

Example 6: Case study: choosing between debt and equity · 4 marks · Case-basedHOTS / competency

'Sitara Solar Ltd.' needs ₹300 crore. (i) The stock market is booming and share prices are at a record high. (ii) The company's earnings swing widely because solar subsidies keep changing. (iii) The tax rate has just been raised. (iv) Other solar companies in India have debt-equity ratios of about 1:1.
(a) Identify the factor in each of (i)-(iv). (2 marks)
(b) Which of them favour equity and which favour debt? (2 marks)

Try it first, then show the solutionSolution

(a) (i) stock market conditions; (ii) risk consideration (business risk) / cash flow; (iii) tax rate; (iv) capital structure of other companies (½ mark each).
(b) Equity: (i) bullish market, (ii) high business risk; debt: (iii) higher tax makes debt cheaper; (iv) a guide only, not to be followed blindly given high business risk (2 marks).

Answer: (a) (i) Stock market conditions; (ii) risk consideration (high business risk, unstable cash flows); (iii) tax rate; (iv) capital structure of other companies. (b) A booming market and high business risk favour equity; a higher tax rate favours debt because interest is tax-deductible; the industry norm of 1:1 is a guide, but with higher business risk Sitara should use less debt than the norm.

Exam tips

Capital structure was a 4-mark question in the 2026 board paper 66/5/1 (Q27, leverage and returns) and a 3-mark question in the 2024-25 sample paper (Q23) and 2026-27 sample paper (Q23(A)); 1-mark items on factors, EPS and risk appear almost every year.
In leverage questions, write RoI and the interest rate side by side before concluding.
Show the EBIT-EPS table line by line; method marks are given for each line.
Financial Management and Financial Markets together carry 15 of the 80 theory marks in 2026-27.

Practice questions on Capital Structure and Financing Decision

Write each answer on paper first. Open the hint only if you are stuck, and the answer only when you have finished.

Q1 · 1 mark · MCQBoard level
Debt is considered a cheaper source of finance mainly because:
(a) lenders take more risk
(b) interest is a tax-deductible expense
(c) debt never has to be repaid
(d) dividends are tax-deductible
Hint
Tax shield.
Answer
(b) interest is a tax-deductible expense
Q2 · 1 mark · Short answerBoard level
What is trading on equity? (1 mark)
Hint
Fixed financial charges.
Answer
The increase in profit earned by equity shareholders due to the presence of fixed financial charges like interest; it is profitable when RoI exceeds the cost of debt.
Q3 · 4 marks · Short answerBoard level
Explain any four factors affecting the choice of capital structure. (4 marks)
Hint
Four groups.
Answer
Any four with a line each: cash flow position; interest coverage ratio; debt service coverage ratio; return on investment; cost of debt; tax rate; cost of equity; floatation costs; risk consideration; flexibility; control; regulatory framework; stock market conditions; capital structure of other companies.
Q4 · 2 marks · Short answerHarder board level
A company's EBIT is ₹15 lakh and annual interest is ₹5 lakh. Calculate the interest coverage ratio and state what it indicates. (2 marks)
Hint
EBIT ÷ interest.
Answer
ICR = 15 ÷ 5 = 3 times. EBIT covers interest three times; the higher the ratio, the lower the risk of failing to meet interest obligations (though ICR ignores repayment and cash balance).
Q5 · 2 marks · Short answerHarder board level
A company earns EBIT of ₹9 lakh on total investment of ₹60 lakh and can borrow at 11%. Should it use more debt to raise EPS? Justify. (2 marks)
Hint
RoI vs 11%.
Answer
RoI = 9 ÷ 60 × 100 = 15%, which is higher than the 11% cost of debt, so trading on equity is favourable and more debt can raise EPS, within limits set by financial risk.
Q6 · 4 marks · Short answerHarder board level
Explain the factors affecting the financing decision. (4 marks)
Hint
Cost, risk, floatation, cash flow, fixed operating cost, control, capital market.
Answer
Any four: (1) cost: cheapest source preferred; (2) risk of each source; (3) floatation costs: higher cost makes a source less attractive; (4) cash flow position: stronger cash flows make debt more viable; (5) fixed operating costs: if high, reduce fixed financing costs (less debt); (6) control: more equity may dilute control; (7) state of capital market: rising market favours equity.
Q7 · 1 mark · Assertion-reasonHarder board level
Assertion (A): Higher use of debt increases the financial risk of a company.
Reason (R): Payment of interest and repayment of principal are obligatory.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Hint
Fixed financial charges.
Answer
(a) Both A and R are true and R is the correct explanation of A.
Q8 · 3 marks · Short answerHarder board level
A company has PAT of ₹4.2 lakh, depreciation ₹1 lakh, interest ₹2.4 lakh, no preference shares and a loan repayment of ₹2 lakh due this year. Calculate DSCR and comment. (3 marks)
Hint
Cash profit ÷ debt service.
Answer
DSCR = (4.2 + 1 + 2.4) ÷ (2.4 + 2) = 7.6 ÷ 4.4 ≈ 1.73. Cash profits cover debt service about 1.73 times; it can meet its commitments with some buffer, but the margin is not large, so it should add debt cautiously.
Q9 · 3 marks · Short answerHOTS / competency
Suppose two companies in the same industry have equal RoI. Company A has very high fixed operating costs (rent, salaries); Company B has low fixed operating costs. Which can use more debt and why? (3 marks)
Hint
Business risk + financial risk.
Answer
Company B. Higher fixed operating costs mean higher business (operating) risk. Total risk = business risk + financial risk, so a firm with high business risk should keep financial risk (debt) low. B, with low business risk, has greater capacity to use debt.
Q10 · 3 marks · Short answerHOTS / competency
'If EPS rises when debt is added, the company should always add more debt.' Do you agree? (3 marks)
Hint
Cost of equity, share value.
Answer
No. More debt raises financial risk, so shareholders expect a higher return (cost of equity rises); beyond a point, the share price may fall in spite of higher EPS. The aim is to maximise the value of equity shares, not EPS alone; the optimal capital structure balances risk and return. Flexibility and cash-flow limits also restrict debt.

Capital Structure and Financing Decision: frequently asked questions

What is capital structure in Class 12 Business Studies?

The proportion of owners' funds (equity, retained earnings) and borrowed funds (debentures, loans) in a firm's long-term finance, measured as debt ÷ equity or debt ÷ (debt + equity).

What is trading on equity?

Using fixed-cost debt to increase the return to equity shareholders. It raises EPS only when the return on investment is higher than the cost of debt.

Why is debt cheaper but riskier than equity?

Lenders get assured interest and repayment and interest is tax-deductible, so debt costs less; but those payments are compulsory, so default can lead to liquidation.

What factors affect capital structure?

Cash flow, ICR, DSCR, RoI, cost of debt, tax rate, cost of equity, floatation costs, risk, flexibility, control, regulation, stock market conditions and other companies' capital structure.
