Time Value of Money means that money available today is worth more than the same amount in the future.
Reasons:
Money today can earn interest
Inflation reduces future purchasing power
Risk and uncertainty
If you have ₹10,000 today and invest it at 10% interest, after one year it becomes:
₹10,000 × 1.10 = ₹11,000
So ₹10,000 today = ₹11,000 after one year at 10% interest.
Financial evaluation techniques like Net Present Value, Internal Rate of Return, and Benefit-Cost Ratio are based on the concept of Time Value of Money.
