In simple words, profit maximization means a business wants to earn the highest possible profit in the short run. Wealth maximization means increasing the overall value (share price) of the firm and its shareholders' wealth over a long period. Let us compare both and understand why wealth maximization is better.
๐ด Profit Maximization
Focuses on increasing net profit immediately. Example: A company cuts raw material quality to reduce cost and earn more profit this year.
Drawbacks: Ignores time value of money. Ignores risk. Focuses only on short-term. Harms brand in the long run.
๐ข Wealth Maximization
Focuses on maximizing the market value (share price) of the company. Example: Tata Motors focuses on innovation and long-term growth.
Advantages: Considers TVM. Considers risk. Looks at long-term benefits. Benefits all stakeholders.
Why Wealth Maximization is Superior
A rupee today is worth more than a rupee tomorrow. Wealth maximization discounts future cash flows to their present value, making decisions more accurate.
Higher risk means higher required return. Wealth maximization adjusts the discount rate based on risk, while profit maximization ignores it completely.
Short-term profit tricks (cutting quality, avoiding R&D) destroy long-term value. Wealth maximization ensures decisions add value sustainably.
The concept of Time Value of Money (TVM) says that a rupee received today is more valuable than a rupee received in the future. This is because money today can be invested to earn returns. TVM is the backbone of all financial decision-making.
Areas Where TVM is Important
โน1,00,000 invested at 10% for 1 year becomes โน1,10,000. Keeping the same money idle means losing โน10,000 of potential income. TVM helps investors choose between options based on their present and future values.
ABC Ltd. is deciding whether to buy a machine for โน5,00,000 that generates โน1,50,000/year for 4 years. Using NPV (based on TVM), the company checks if the present value of future cash flows exceeds โน5,00,000.
A person starting SIP of โน5,000/month at age 25 will accumulate a much larger corpus by age 60 than someone starting at age 40. The extra 15 years of compounding makes a huge difference โ this is TVM in personal finance.
Banks use TVM to calculate EMIs. The interest paid on a home loan is the cost of using future money today. A โน30 lakh loan at 8% for 20 years costs significantly more in total because of TVM.
Financial management means planning, organizing, and controlling the financial activities of a business. It is based on certain fundamental principles that guide all financial decisions.
Higher the risk, higher the return. Investing in stocks gives higher returns than a fixed deposit, but stocks carry more risk. Businesses must balance risk and return carefully.
Money today is worth more than money tomorrow. Used in all investment, loan, and capital budgeting decisions.
Financial decisions should be based on actual cash flows, not accounting profits. A company may show profit on paper but still face a cash shortage due to delayed receivables.
Only the additional (incremental) cash flows from a decision matter. If a company launches a new product, only the new revenue and new costs are considered โ not the existing ones.
Do not put all eggs in one basket. Investing in different assets or businesses reduces overall portfolio risk.
Financial markets reflect all available information in share prices. Companies must make decisions assuming markets are efficient and prices are fair.
Future Value (FV) is the value that money today will grow into after a certain period at a given interest rate. Present Value (PV) is the current value of money that will be received in the future, discounted at a certain rate.
๐ Future Value โ Solved Example
Ramesh deposits โน50,000 at 10% p.a. for 3 years.
Ramesh receives โน66,550 after 3 years. The โน16,550 extra is interest earned.
๐ Present Value โ Solved Example
Sunita will receive โน1,00,000 after 3 years. Discount rate = 10%.
โน1,00,000 received after 3 years is worth only โน75,131 today.
Key Differences
| Basis | Present Value (PV) | Future Value (FV) |
|---|---|---|
| Meaning | Current worth of future money | Future worth of current money |
| Method | Discounting (รท by interest factor) | Compounding (ร by interest factor) |
| Used In | Bond valuation, loan analysis, NPV | Savings, pension, investment planning |
| Example User | Bank manager evaluating repayments | Investor planning for retirement |
Leverage means using borrowed funds (debt) to increase potential return on investment โ like using a lever to lift heavy objects with less effort. There are two main types: Operating Leverage and Financial Leverage.
โ๏ธ Operating Leverage
Use of fixed costs in operations. High fixed costs = high operating leverage. A small increase in sales leads to a large increase in operating profit.
Example: A factory with high machinery costs (fixed) earns much more profit once sales cross the break-even point.
๐ฐ Financial Leverage
Use of debt to finance operations. When return on borrowed money > interest paid, shareholders benefit.
Example: XYZ Ltd. borrows โน10 lakh at 10% interest and earns 15% return. Extra 5% = โน50,000 goes to shareholders, boosting ROE.
Risk in Leverage
Too much leverage is dangerous. If business earnings fall, the company must still pay fixed interest. This leads to financial distress.
Cost of capital is the minimum rate of return a company must earn on its investments to satisfy all its investors โ both shareholders and lenders. In simple terms, it is the price a company pays for using funds.
Components
Interest rate paid on borrowed money, adjusted for tax. If a company borrows at 12% and tax rate is 30%, Kd = 12% ร (1 - 0.30) = 8.4%.
Return expected by shareholders. If shareholders expect 15% return, Ke = 15%.
Average cost of all sources of finance, weighted by proportion. Example: 60% equity (15%) + 40% debt (10%) โ WACC = (0.60ร15%) + (0.40ร10%) = 9% + 4% = 13%.
Why Cost of Capital is Important
| Use | How Cost of Capital Helps |
|---|---|
| Investment Decisions | Accept project only if return > WACC (adds value to firm) |
| Capital Structure | Helps find the best debt-equity mix that minimizes WACC |
| Firm Valuation | Lower WACC โ higher present value of cash flows โ higher firm value |
| Performance Evaluation | WACC is used as a benchmark to evaluate divisional performance |
Every business needs funds to operate and grow. These funds are raised from different sources depending on the purpose and time period required.
Used for permanent needs like land, machinery, buildings. Examples: Equity Share Capital โ Zomato raised crores through its IPO. Debentures/Bonds โ 10-year debentures at 9% interest. Retained Earnings โ profits ploughed back instead of paying dividends.
Used for replacing machinery or vehicles. Examples: Term Loans from Banks โ taken for 3-5 years for a specific purpose. Preference Shares โ fixed dividends, redeemable after 5-7 years. Lease Financing โ a startup leases office space instead of buying it outright.
Used for day-to-day operational needs (working capital). Examples: Bank Overdraft โ withdraw beyond bank balance up to a limit. Trade Credit โ suppliers allow 30-90 days credit. Commercial Paper โ short-term notes issued by large companies. Cash Credit โ revolving credit facility from banks.
WACC is the average cost of all funds used by a company, weighted by the proportion of each source. It represents the overall financing cost and acts as the hurdle rate for investment decisions.
Numerical Example
| Source | Amount (โน) | Weight | Cost | Weighted Cost |
|---|---|---|---|---|
| Equity | 6,00,000 | 0.60 | 15% | 9.0% |
| Debt (after 30% tax) | 4,00,000 | 0.40 | 10% โ 7% | 2.8% |
| WACC | 11.8% | |||
The company must earn at least 11.8% on all its investments to satisfy all providers of funds.
Rationale for Using WACC
Projects earning more than WACC add value to the firm; those earning less should be rejected.
Companies try to minimize WACC by finding the right debt-equity mix, which maximizes firm value.
Lower WACC = higher present value of future cash flows = higher market capitalization.
Capital structure is the mix of debt and equity used by a company to finance its assets. The right capital structure minimizes cost of capital and maximizes firm value. Several key factors influence this decision.
Debt is cheaper than equity because interest is tax-deductible. However, too much debt increases financial risk. Companies choose a mix that gives the lowest WACC.
High debt means high fixed interest payments. If earnings fall, the company may not afford interest. Highly leveraged companies face bankruptcy risk during downturns.
Risky industries (startups, real estate) should use less debt. Stable industries (FMCG, utilities) can safely afford more debt in their structure.
Interest on debt is tax-deductible (Tax Shield). Companies in higher tax brackets benefit more from debt financing.
Issuing more equity dilutes ownership and voting rights. Promoters who want to maintain control prefer debt over equity.
During low interest rate periods, companies prefer debt. During high interest rates or bullish stock markets, companies prefer equity.
The NOI (Net Operating Income) Approach states that the total value of a firm is independent of its capital structure. Firm value depends only on the capitalization rate applied to EBIT.
Given Data
| Item | Value |
|---|---|
| EBIT (Earnings Before Interest and Tax) | โน80,000 |
| Interest on Debt | โน16,000 |
| Debt (Debentures) | โน2,00,000 |
| Overall Capitalization Rate (Ko) | 20% |
Step 1 โ Total Value of Firm (V)
Step 2 โ Market Value of Equity (E)
Step 3 โ Verify Cost of Equity (Ke)
Modigliani and Miller (MM) proposed in 1958 that the value of a firm is independent of its capital structure in a perfect market without taxes. This is MM Proposition I (No Taxes).
Core Argument
MM argued that how a company finances itself (debt or equity) does not change total firm value. Value depends only on earning power and business risk, not on financing structure.
If Company B had higher value, investors from Company A would borrow money personally and buy B's shares (called "homemade leverage" or arbitrage). This buying/selling continues until both firms have equal value โ eliminating any advantage of debt.
Why Capital Structure is Irrelevant โ Key Assumptions
| Assumption | Meaning |
|---|---|
| No Taxes | Interest is not tax-deductible โ no advantage of debt |
| No Transaction Costs | No costs of buying/selling securities |
| Equal Borrowing Rates | Investors and companies borrow at same rate |
| Perfect Information | All investors have equal access to information |
| No Bankruptcy Costs | Distress does not cause loss of value |
The Traditional Approach says there IS an optimal capital structure that minimizes WACC and maximizes firm value. Unlike MM, this approach believes capital structure decisions DO matter.
The Theory โ 3 Stages
| Stage | Debt Level | WACC | Firm Value |
|---|---|---|---|
| Stage 1 | Low to Moderate Debt | โฌ Decreasing | โฌ Increasing |
| Stage 2 (Optimal) | Optimal Mix | โฌ Minimum | โฌ Maximum |
| Stage 3 | Excessive Debt | โฌ Increasing | โฌ Decreasing |
Applying to DEF Ltd.
DEF Ltd. currently has low debt. Adding moderate debt is justified because: interest is tax-deductible โ reduces WACC โ increases firm value. The CFO's reasoning is correct at this stage.
Excessive debt โ increased financial risk โ credit rating falls โ future borrowing becomes expensive. Investors demand higher returns (higher Ke) โ WACC rises again โ firm value falls.
DEF Ltd. should add debt gradually but stop at the optimal point where WACC is minimum. Beyond that, the risks outweigh the benefits.
Working Capital = Current Assets โ Current Liabilities. It is the money needed for day-to-day business operations. Every business needs adequate working capital to function smoothly.
A steel manufacturer needs cash to buy iron ore and coal before selling the final product. Without working capital, production stops immediately.
Workers need monthly salaries regardless of whether the company has collected payment from customers. Working capital ensures timely salary payments.
A medicine company (like DEF Ltd.) must always have stock ready for hospitals and pharmacies. Running out of stock = loss of sales and customer trust.
Most B2B businesses sell on 30-60 day credit. During this waiting period, the company's money is locked in debtors. Working capital bridges this gap.
Situations Where Working Capital is Crucial
๐ Seasonal Businesses
A sweet shop (mithai shop) needs high working capital before Diwali to stock up on ingredients, packaging, and manpower for the festive rush.
๐ Export Companies
An exporter may wait 90 days for payment from foreign buyers. Without adequate working capital, they cannot produce the next batch โ operations halt.
NPV Calculation Table
| Year | Cash Flow (โน) | PV Factor @ 12% | Present Value (โน) |
|---|---|---|---|
| 1 | 2,00,000 | 0.893 | 1,78,600 |
| 2 | 2,50,000 | 0.797 | 1,99,250 |
| 3 | 3,00,000 | 0.712 | 2,13,600 |
| 4 | 3,50,000 | 0.636 | 2,22,600 |
| 5 | 4,00,000 | 0.567 | 2,26,800 |
| Total Present Value of Inflows | 10,40,850 | ||
| Less: Initial Investment | (8,00,000) | ||
| NET PRESENT VALUE (NPV) | โน2,40,850 | ||
NPV = โน2,40,850 (POSITIVE). Since NPV > 0, the project earns more than the required 12% return. It adds value to ABC Ltd. and should be implemented.
Working Capital Management (WCM) involves managing short-term assets (cash, debtors, inventory) and short-term liabilities (creditors, bank loans) to ensure the company can meet daily obligations while maximizing profitability.
Positive WC = Can pay short-term debts. | Negative WC = Financial trouble.
Key Determinants of Working Capital
Service companies (IT firms) need less WC. Manufacturing companies need more WC to hold raw materials, WIP, and finished goods.
Longer production cycles (e.g., shipbuilding) require more WC because money is tied up in WIP for a long time before cash is received.
If a company gives 90-day credit to customers instead of 30 days, more money is locked in debtors โ significantly increasing WC requirements.
Businesses like Patanjali or festive sweet shops need extra WC before peak season to build up inventory and pay for materials in advance.
If suppliers give 60-day credit, the company effectively uses the supplier's money โ reducing its own WC requirement significantly.
Rapidly growing companies need more WC to support higher sales volumes, more inventory, and larger debtor balances.
IRR (Internal Rate of Return) is the discount rate at which NPV = 0. We use the trial and error (interpolation) method.

Interpolation Formula
IRR = 16.47% > Required Rate of Return = 15%. Since the project earns more than the investor's required return, the tech startup investment should be ACCEPTED. It will generate positive returns above the hurdle rate.
