Top Capital Budgeting Techniques & Real-Life Examples

Every business — from a local tea stall to big corporates like Reliance or Tata — faces one key question:
“Where should we invest our money?”
This is where Capital Budgeting comes in. It helps decide which long-term projects will be profitable in the future.
In simple words, capital budgeting means deciding how to spend money on long-term assets like machinery, buildings, or new products to earn the best returns.
Let’s understand the top capital budgeting techniques with real-life Indian examples, explained so simply that even a school student can grasp them!

Capital Budgeting Techniques & Real-Life Examples

1. Payback Period Method

Meaning
The Payback Period tells how long it takes to recover the money invested in a project. It’s one of the simplest methods used by small businesses.

Formula
Payback Period=Initial InvestmentAnnual Cash Inflow\text{Payback Period} = \frac{\text{Initial Investment}}{\text{Annual Cash Inflow}}Payback Period=Annual Cash InflowInitial Investment

Example
A tea café in Delhi invests ₹5,00,000 in a new outlet.
If the café earns ₹1,00,000 per year:
₹5,00,000÷₹1,00,000=5 years₹5,00,000 ÷ ₹1,00,000 = 5 \text{ years}₹5,00,000÷₹1,00,000=5 years
So, the café will recover its investment in 5 years.
✅ Pros: Simple and easy to use
❌ Cons: Ignores time value of money and post-payback profits

2. Net Present Value (NPV) Method

Meaning
NPV (Net Present Value) considers the time value of money, meaning that ₹1 today is more valuable than ₹1 tomorrow. It shows the project’s total profitability in today’s value.

Formula
NPV=Present Value of Cash Inflows−Initial Investment\text{NPV} = \text{Present Value of Cash Inflows} - \text{Initial Investment}NPV=Present Value of Cash Inflows−Initial Investment

Example
A solar panel company in Mumbai invests ₹10,00,000 in a project expected to earn ₹3,00,000 per year for 5 years.
At a 10% discount rate, the total present value is ₹11,37,900.
NPV=₹11,37,900−₹10,00,000=₹1,37,900NPV = ₹11,37,900 - ₹10,00,000 = ₹1,37,900NPV=₹11,37,900−₹10,00,000=₹1,37,900
Since NPV is positive, the project is profitable.
✅ Pros: Considers time value of money
❌ Cons: Needs estimation of future cash flows and discount rate

3. Internal Rate of Return (IRR)

Meaning
IRR (Internal Rate of Return) is the rate at which the NPV becomes zero. It helps compare different investments.

Example
Suppose Infosys invests ₹50 lakh in a new software product.
If the IRR is 18% and the company’s required rate is 12%, the project is accepted, as 18% > 12%.
✅ Pros: Considers time value of money
❌ Cons: Complex to calculate manually

4. Profitability Index (PI)

Meaning
PI (Profitability Index) measures the ratio between the present value of future cash inflows and the initial investment.

Formula
PI=Present Value of Future Cash InflowsInitial InvestmentPI = \frac{\text{Present Value of Future Cash Inflows}}{\text{Initial Investment}}PI=Initial InvestmentPresent Value of Future Cash Inflows

Example
A startup in Bengaluru invests ₹2,00,000 with an expected return of ₹2,40,000 (present value).
PI=₹2,40,000÷₹2,00,000=1.2PI = ₹2,40,000 ÷ ₹2,00,000 = 1.2PI=₹2,40,000÷₹2,00,000=1.2
Since PI > 1, the project is profitable.

5. Accounting Rate of Return (ARR)

Meaning
ARR (Accounting Rate of Return) calculates the average annual accounting profit as a percentage of the initial investment.

Formula
ARR=Average Annual ProfitInitial Investment×100ARR = \frac{\text{Average Annual Profit}}{\text{Initial Investment}} × 100ARR=Initial InvestmentAverage Annual Profit×100

Example
A garment factory in Tirupur invests ₹10 lakh and earns ₹2 lakh yearly.
ARR=2,00,00010,00,000×100=20%ARR = \frac{2,00,000}{10,00,000} × 100 = 20%ARR=10,00,0002,00,000×100=20%
If the company’s expected rate is 15%, this project is worth investing in

6. Discounted Payback Period (DPB)

Meaning
The Discounted Payback Period considers the time value of money, unlike the regular Payback method.
It gives a more realistic recovery period.

Example
A real estate developer in Pune invests ₹10 crore.
By discounting cash flows, the recovery time is 6 years instead of 5, making the result more accurate.

7. Modified Internal Rate of Return (MIRR)

Meaning
MIRR (Modified Internal Rate of Return) assumes that cash inflows are reinvested at the company’s cost of capital, giving a more realistic result than IRR.

Example
A solar energy company in Gujarat invests ₹20 lakh.
If IRR = 17% but MIRR = 15%, the MIRR gives a clearer, more practical picture of returns.
