Guide
How it works
Use this calculator to estimate net present value.
What this calculator does
The NPV calculator helps estimate the value of future cash flows after discounting them back to today and subtracting the initial investment.
It is useful for:
- investment analysis
- project evaluation
- capital budgeting
- decision-making
Formula
NPV = Present Value of Future Cash Flows - Initial Investment
Where:
- Future Cash Flows = cash expected in future periods
- Discount Rate = required rate of return
- Initial Investment = upfront cost
- NPV = net present value of the investment
Example calculation
If:
- Cash flow year 1 = 30000
- Cash flow year 2 = 35000
- Cash flow year 3 = 40000
- Discount rate = 10%
- Initial investment = 80000
Then:
- NPV discounts each future cash flow back to today
- NPV compares that total present value against the initial investment
- A positive NPV suggests value is being created
What is NPV?
Net present value shows whether an investment is expected to create value after considering the time value of money.

- compare projects
- assess investments
- support capital allocation
- improve financial decision-making
