Net Present Value Calculator

Net Present Value (NPV) is a financial metric that helps investors and businesses evaluate the profitability of an investment or project. It considers the time value of money — meaning that a dollar today is worth more than a dollar in the future.

In simple terms, NPV compares the present value of future cash inflows from an investment to its initial cost. If the NPV is positive, the investment is profitable; if negative, it may not be worth pursuing.

Our free online NPV Calculator is designed to make this process effortless. Just enter your initial investment, expected cash flows, and discount rate — and the calculator instantly displays your NPV along with a clear investment decision (Accept or Reject).

💡 Why Use an NPV Calculator?

Manual NPV calculation can be time-consuming and prone to human error. Using an online NPV calculator saves time and ensures accuracy by performing precise mathematical computations automatically.

Here’s why our tool stands out:

  • Instant Results – Get your NPV in seconds.
  • Error-Free Calculations – Eliminates human calculation mistakes.
  • User-Friendly Interface – Easy to use for professionals and beginners.
  • Automatic Investment Decision – Tells you if your project is profitable or not.
  • Accessible Anytime, Anywhere – 100% web-based, no installation required.

🧠 Understanding the NPV Formula

The general formula for calculating NPV is: NPV=∑t=1nCt(1+r)t−C0NPV = \sum_{t=1}^{n} \frac{C_t}{(1 + r)^t} – C_0NPV=t=1∑n​(1+r)tCt​​−C0​

Where:

  • CtC_tCt​ = Cash flow at time ttt
  • rrr = Discount rate (as a decimal)
  • ttt = Time period (year 1, 2, 3, etc.)
  • C0C_0C0​ = Initial investment

If the result is positive, the investment is profitable. If negative, it means the project may lead to a loss.

📊 Example: Calculate NPV Step-by-Step

Let’s walk through a real example.

Example Scenario:

  • Initial Investment: $10,000
  • Discount Rate: 10%
  • Cash Flows: $3,000, $4,000, $4,500, $5,000

Step 1: Apply the Formula

NPV=3000(1+0.10)1+4000(1+0.10)2+4500(1+0.10)3+5000(1+0.10)4−10000NPV = \frac{3000}{(1+0.10)^1} + \frac{4000}{(1+0.10)^2} + \frac{4500}{(1+0.10)^3} + \frac{5000}{(1+0.10)^4} – 10000NPV=(1+0.10)13000​+(1+0.10)24000​+(1+0.10)34500​+(1+0.10)45000​−10000

Step 2: Calculate

NPV=2727.27+3305.79+3382.35+3415.07−10000NPV = 2727.27 + 3305.79 + 3382.35 + 3415.07 – 10000NPV=2727.27+3305.79+3382.35+3415.07−10000 NPV=12830.48−10000=2830.48NPV = 12830.48 – 10000 = 2830.48NPV=12830.48−10000=2830.48

Step 3: Interpretation

✅ Since NPV = $2830.48 (Positive), the project is Profitable and should be Accepted.

❓ 20 Frequently Asked Questions (FAQs)

1. What is NPV in simple terms?
NPV measures how much profit an investment will make after considering the time value of money.

2. What does a positive NPV mean?
A positive NPV means the investment is profitable and should be accepted.

3. What does a negative NPV mean?
It indicates the investment will likely result in a loss and should be rejected.

4. How does the discount rate affect NPV?
A higher discount rate reduces NPV, while a lower rate increases it.

5. What is a good NPV value?
Any positive NPV suggests profitability, but higher values indicate better returns.

6. Can NPV be zero?
Yes, an NPV of zero means the investment breaks even — no profit or loss.

7. What is the discount rate?
It’s the expected rate of return or cost of capital used to discount future cash flows.

8. Is NPV better than IRR?
Both are useful, but NPV provides an absolute measure of profitability, while IRR gives a percentage return.

9. Can I use NPV for personal investments?
Yes, it can help evaluate real estate, stocks, or any investment with future returns.

10. Does NPV consider risk?
Indirectly, yes — the discount rate often reflects investment risk.

You can input any currency — the symbol $ is just for display.

14. What is the minimum input requirement?
You must enter an investment amount, a discount rate, and at least one cash flow.
