Earnings and Market-Based Valuation for CA Final AFM

Updated 5 October 2026 · Fact-checked

Earnings and market-based valuation estimates a firm's value from its profits or from how the market prices similar firms. Capitalise maintainable earnings at a required rate, or multiply a metric (EPS, EBITDA, book value) by a comparable multiple. For EV multiples, subtract net debt to reach equity value.

Understand Earnings and Market-Based Valuation

A business is worth what it can earn, or what buyers pay for similar businesses. These two ideas give two families of methods. The earnings capitalisation method is intrinsic: you take the profit the business can sustain and divide it by a required rate of return. The market multiple methods are relative: you take a ratio seen in comparable listed firms and apply it to your firm.

Start with the earnings capitalisation method. If maintainable earnings are steady, value = earnings ÷ capitalisation rate. A higher rate means a lower value because the buyer wants more return for the risk. Maintainable earnings are not just last year's profit. You adjust for one-off gains, one-off losses, abnormal items and changes in tax or cost structure.

Now the multiples. The P/E ratio is price per share ÷ EPS. It tells you how many rupees the market pays for ₹1 of earnings. It is an equity multiple, so P/E × earnings gives equity value directly. EV/EBITDA compares enterprise value (equity plus net debt) to operating profit before depreciation. It is an enterprise multiple, so it gives enterprise value. You must subtract net debt to get equity value. Price-to-book (P/B) compares market price to book value per share and suits asset-heavy firms such as banks.

Choose the multiple that fits the case. P/E works for stable, profitable, similarly levered firms. EV/EBITDA works when capital structures or depreciation policies differ, because it ignores both. P/B suits financial firms. Multiples from peers are only useful if the peers match on growth, risk and size.

Key rules to remember

Earnings capitalisation value: Value = Maintainable earnings ÷ Capitalisation rate; Use after-tax earnings with an equity rate for equity value; use pre-interest earnings with a firm-level rate for firm value. Keep earnings and rate consistent.
P/E ratio: P/E = Market price per share ÷ EPS; Equals Market capitalisation ÷ Net profit available to equity shareholders.
Equity value by P/E: Equity value = Maintainable PAT × Peer P/E; Per share value = EPS × P/E.
Earnings yield: Earnings yield = EPS ÷ Price = 1 ÷ (P/E); Capitalisation rate in the earnings method is the earnings yield.
Enterprise value: EV = Market value of equity + Debt − Cash and cash equivalents; Add minority interest and preference capital if given.
EV/EBITDA valuation: EV = EBITDA × Peer EV/EBITDA multiple; Equity value = EV − Net debt; Net debt = Debt − Cash. Do not forget this last step.
Price-to-book: P/B = Market price per share ÷ Book value per share; Equity value = Net worth × Peer P/B.
Average multiple: Peer multiple = Σ multiples ÷ n; Use the average or median as the question directs. Adjust only if the question asks for a premium or discount.

How to solve Earnings and Market-Based Valuation questions

Use this order for any earnings or market-multiple question.

1Read what is asked: equity value, enterprise value, or value per share.
2Identify the method the question names or the data supports: capitalisation rate, P/E, EV/EBITDA or P/B.
3Find maintainable earnings. Remove one-off items and adjust for tax, as the question directs.
4Match the metric to the multiple. PAT goes with P/E, EBITDA with EV/EBITDA, net worth with P/B.
5Compute the peer multiple (average or median) or the capitalisation rate.
6Apply the multiple to your firm's metric to get the value.
7Convert if needed. For EV, deduct net debt to get equity value. Divide by shares for per-share value.
8State the result with a short interpretation, such as value compared with the current market price.

Quickest way: Match-and-multiply check

When to use it: Use when the question gives peer data and asks for a quick value under time pressure.

Write the metric and the multiple type side by side. Confirm they match.
Compute the average peer multiple in one line.
Multiply to get the value.
If it is an EV multiple, subtract debt and add cash immediately.
Divide by shares only at the very end and check the unit (₹ lakh or crore).

Common mistakes in Earnings and Market-Based Valuation

Applying EV/EBITDA and reporting the result as equity value.
Students stop after multiplying EBITDA by the multiple.
Fix: Always subtract net debt after the multiplication and label EV and equity value separately.
Using reported profit without adjusting for one-off items.
The question buries a non-recurring gain or loss in a note.
Fix: Scan notes for exceptional items first and build a maintainable earnings line.
Mixing pre-tax earnings with a post-tax capitalisation rate.
The tax rate is given late in the question.
Fix: Decide the rate's basis, then convert earnings to match, with tax deducted if the rate is post-tax.
Applying P/E to EBITDA or EV/EBITDA to PAT.
Multiples look alike and are quickly picked from a table.
Fix: Remember that equity multiples go with equity earnings and EV multiples go with operating earnings.
Using the wrong number of shares or the wrong net debt sign.
Cash is added to debt by habit.
Fix: Net debt is debt minus cash. Check the share count against the question before dividing.

Worked examples

Example 1

Case: Meera Ltd has a profit after tax of ₹90 lakh, which includes a one-off after-tax gain of ₹10 lakh from sale of land. A buyer wants a return of 16% on equity. It has 4 lakh equity shares. Value the equity using the earnings capitalisation method and find the value per share.

Show the solution

Maintainable PAT = ₹90 lakh − ₹10 lakh = ₹80 lakh.
Equity value = ₹80 lakh ÷ 0.16 = ₹500 lakh.
Value per share = ₹500 lakh ÷ 4 lakh shares = ₹125.

Answer: Equity value is ₹5,00,00,000 (₹500 lakh) and value per share is ₹125.

Example 2

Case: Arjun Ltd has EBITDA of ₹60 crore, debt of ₹100 crore and cash of ₹20 crore. It has 8 crore shares. Three listed peers trade at EV/EBITDA of 8, 10 and 12. Estimate the equity value and the value per share using the average peer multiple.

Show the solution

Average multiple = (8 + 10 + 12) ÷ 3 = 10.
Enterprise value = ₹60 crore × 10 = ₹600 crore.
Net debt = ₹100 crore − ₹20 crore = ₹80 crore.
Equity value = ₹600 crore − ₹80 crore = ₹520 crore.
Value per share = ₹520 crore ÷ 8 crore shares = ₹65.

Answer: Enterprise value is ₹600 crore, equity value is ₹520 crore and value per share is ₹65.

Exam tips

Read the notes to the accounts first. Exceptional items and tax changes often hide there, and they drive the maintainable earnings.
Show the multiple and the metric on separate lines. Examiners award marks for the method even if the arithmetic slips.
Label every result as enterprise value or equity value. Mixing them is a frequent loss of marks.
In case-scenario MCQs, check which metric the multiple pairs with before computing anything.
Write one line of interpretation, for example whether the estimated value is above or below the market price.

Earnings and Market-Based Valuation: frequently asked questions

What is the difference between EV/EBITDA and P/E valuation?

P/E values equity directly using profit after tax and is affected by debt and depreciation. EV/EBITDA values the whole business using operating profit before depreciation and ignores capital structure. With EV/EBITDA you deduct net debt to reach equity value.

When should I use the earnings capitalisation method?

Use it when earnings are stable and a required rate of return is given or can be derived. It works best for mature businesses. First adjust earnings to a maintainable level.

Which multiple suits banks and asset-heavy firms?

Price-to-book is commonly used for banks and asset-heavy firms because their value is closely tied to net worth. EBITDA is less meaningful for banks because interest is their core operating item.

How is the capitalisation rate linked to P/E?

The earnings yield, EPS ÷ price, is the inverse of the P/E ratio. A P/E of 10 implies a capitalisation rate of 10%. Valuing at a given P/E is the same as capitalising earnings at that yield.
