How To Calculate Net Present Value

Net Present Value (NPV) is a crucial financial metric used to evaluate the profitability of an investment. It takes into account the time value of money and helps in determining whether an investment is worthwhile.

Formula: The Net Present Value is calculated using the formula: ���=∑�=0����(1+�)�−�NPV=∑t=0n​(1+r)tCFt​​−I where:

  • ���CFt​ is the cash flow at time �t
  • r is the discount rate
  • I is the initial investment
  • n is the number of periods

How to Use:

  1. Enter the initial investment in the “Initial Investment” field.
  2. Input the discount rate as a percentage in the “Discount Rate” field.
  3. Provide the cash flows separated by commas in the “Cash Flows” field.
  4. Click the “Calculate” button to obtain the Net Present Value.

Example: Suppose you have an initial investment of $10,000, a discount rate of 8%, and cash flows of $2,000 per year for three years. Enter the values, click “Calculate,” and find the Net Present Value.


  1. Q: What is Net Present Value? A: Net Present Value (NPV) is a financial metric that calculates the present value of future cash flows discounted at a specific rate.
  2. Q: Why is NPV important? A: NPV helps in evaluating the profitability of an investment by considering the time value of money.
  3. Q: How do I interpret a negative NPV? A: A negative NPV indicates that the investment may not be profitable, and caution is needed.
  4. Q: Can NPV be zero? A: Yes, an NPV of zero suggests that the investment is expected to break even.
  5. Q: What is the significance of the discount rate? A: The discount rate reflects the opportunity cost of investing money elsewhere.
