Capital Budgeting Impact
Imagine you're deciding whether to buy a new laptop for college. You'll spend ₹60,000 today, but you expect it to help you earn ₹10,000 extra per year through freelancing for the next 4 years. Is that a good decision? You're not just comparing ₹60,000 with ₹40,000 — because money today is worth more than money tomorrow, and you have to account for risk, alternatives, and timing.
That's the core of capital budgeting: evaluating whether a long-term investment (buying a machine, building a factory, launching a product) is worth the money you put in today.
The Intuition
Capital budgeting answers one question: "Will this investment create more value than it costs?"
But it's not simple arithmetic. Three things make it tricky:
- Time value of money — ₹1 lakh today is not the same as ₹1 lakh five years from now. You could invest that ₹1 lakh today and earn interest.
- Uncertainty — future cash flows are guesses, not guarantees.
- Opportunity cost — if you put money into Project A, you cannot put it into Project B.
So capital budgeting techniques adjust future cash flows for time and risk, then compare them to the initial cost.
The Precise Statement
Capital budgeting is the process of evaluating and selecting long-term investments by comparing the present value of expected future cash inflows against the initial cash outflow, using techniques like Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period, and Profitability Index.
The impact of capital budgeting is the difference between the value the investment creates and what it costs — measured in today's money.
The Key Techniques (at a glance)
| Technique | What it tells you | Decision rule |
|---|
| Net Present Value (NPV) | Total value created in today's rupees | Accept if NPV > 0 |
| Internal Rate of Return (IRR) | The rate of return the project earns | Accept if IRR > cost of capital |
| Payback Period | How fast you recover your investment | Accept if within target period |
| Profitability Index | Value created per rupee invested | Accept if PI > 1 |
Why It Matters
A bad capital budgeting decision can sink a company. If you overestimate future cash flows, you might build a factory that never earns back its cost. If you underestimate, you might reject a project that would have been profitable. …
