Time Value of Money and NPV
The Time Value of Money (TVM) is the concept that money available now is worth more than the same amount in the future due to its earning potential. Net Present Value (NPV) uses this principle to evaluate investments by discounting future cash flows to their present value. A positive NPV indicates a profitable investment, while a negative NPV suggests a loss, helping businesses make informed financial decisions.

💡 Key Takeaways
- Grasp the time value of money: why a dollar today is worth more than a dollar tomorrow due to earning potential.
- Compute present value and future value using discounting and compounding concepts across different time periods.
- Use Net Present Value (NPV) to evaluate investments by discounting all expected cash flows back to present value.
- Interpret NPV results for decision-making: a positive NPV suggests value creation, while considering assumptions like the discount rate and cash flow estimates.
❓ Frequently Asked Questions
What is the time value of money (TVM)?
Money today is worth more than the same amount in the future because it can earn interest or generate returns. TVM adjusts for this by comparing cash flows at a common point in time using a discount rate.
What is net present value (NPV) and how is it calculated?
NPV is the sum of the present values of all future cash flows minus the initial investment: NPV = Σ CF_t / (1+r)^t − I0, where r is the discount rate and t is time.
What does a positive NPV indicate?
A positive NPV means the investment is expected to create value above its cost at the chosen discount rate; it is typically considered profitable.
How does the discount rate affect NPV?
A higher discount rate lowers the present value of future cash flows, reducing NPV; a lower rate increases present value and NPV.
Why use NPV to evaluate investments instead of just adding up cash flows?
NPV accounts for the time value of money and the opportunity cost of capital, providing a single monetary measure of profitability that is easier to compare across projects.
