Calculate Net Present Value Calculator
Enter your financial inputs below to compute Net Present Value (NPV) ($).
Calculation Results
Calculated using commercial accounting formula: NPV = Sum(CF_t / (1+r)^t) - Initial Outlay (for t=1..5 years)
Quick Summary
The Net Present Value (NPV) Calculator evaluates investment feasibility by calculating the difference between the present value of projected cash inflows and the initial capital outlay.
- Net Present Value (NPV $): Net value created by the investment in today's dollars.
- Present Value of Inflows ($): Total discounted cash inflows over a 5-year horizon.
- Profitability Index (PI): Ratio of discounted inflows to initial outlay.
How to Use the Net Present Value Calculator
- Enter total Initial Investment Outlay.
- Enter expected Annual Net Cash Inflow.
- Enter your Discount Rate / Cost of Capital (%).

Net Present Value Calculator Formula & Method
This tool utilizes standard accounting algorithms to compute business returns:
Where t = Year, r = Discount Rate
Where:
- Cash Inflow_t: Net cash earnings generated in year t.
- r: Annual discount rate or hurdle rate.
- Initial Outlay: Capital spent in Year 0.
Worked Example
Example: $100,000 Outlay, $30,000 Annual Inflow (5 Yrs) at 10% Discount Rate
- Initial Outlay: $100,000.00
- Annual Inflow: $30,000.00 / year (5 Years)
- Discount Rate: 10.0%
Applying the formula yields:
PV of Inflows (5 Yrs): $113,723.60
Net Present Value (NPV): $113,723.60 - $100,000.00 = +,723.60 (Accept Project)
What This Calculator Includes vs. Does Not Include
What This Calculator Includes
- Time Value of Money (TVM): Discounts future cash flows using cost of capital.
- Capital Expenditure Decision Rule: Recommends project acceptance when NPV >= 0.
What This Calculator Does Not Include
- Non-Monetary Strategic Factors: Brand equity or non-financial intangible benefits.
Tips & Best Practices
- Accept Projects with Positive NPV: Any project with NPV >= 0 creates shareholder value.
- Use Company WACC as Discount Rate: Set discount rate to your Weighted Average Cost of Capital.
Common Mistakes to Avoid
- Using Inflation Rate Instead of Hurdle Rate: Hurdle rates must reflect capital opportunity cost, not just inflation.
Frequently Asked Questions (FAQ)
What is Net Present Value (NPV)?
Net Present Value is the difference between the present value of cash inflows and the present value of cash outflows over a period of time.
How do you calculate NPV?
Discount each future cash inflow using PV = CF / (1+r)^t, sum the discounted inflows, and subtract the initial capital outlay.
What does a positive NPV mean?
A positive NPV means the investment generates a return higher than the discount rate, adding dollar value to the business.
What does a negative NPV mean?
A negative NPV means the project fails to meet the required hurdle rate, indicating capital loss if accepted.
What is the difference between NPV and IRR?
NPV measures total dollar value added in currency. IRR measures the percentage rate of return where NPV equals zero.
How does discount rate affect NPV?
Higher discount rates reduce the present value of future cash flows, lowering total NPV.
Why is NPV preferred over simple payback period?
NPV factors in the time value of money and evaluates cash flows generated across the entire project lifecycle.
Can NPV be calculated with unequal cash flows?
Yes, discount each year's specific cash flow individually before summing them together.
Is this NPV calculator free?
Yes, TibCal's Net Present Value Calculator is 100% free.
