# NPV Calculator-Net Present Value

Net Present Value (NPV) considers the time value of money. The NPV of a property is the dollar amount difference between the “present value” of all future cash flows anticipated from the investment and the cash amount required to purchase those cash flows. A positive net present value indicates that an investment is earning more than the discount rate. A negative net present value indicates an investment is earning less than the discount rate but may be earning a positive rate. The basic formula for Net Present Value is-Net Present Value = Present Value of Future Cash Flows-Initial Cash Investment.

## Difference between Present Value (NPV) and Internal Rate of Return (IRR)

Net present value (NPV) is the difference between the present value of cash inflows and the present value of cash outflows over a period of time. By contrast, the internal rate of return (IRR) is a calculation used to estimate the profitability of potential investments.

Both of these measurements are primarily used in capital budgeting, the process by which companies determine whether a new investment or expansion opportunity is worthwhile. Given an investment opportunity, a firm needs to decide whether undertaking the investment will generate net economic profits or losses for the company.

• NPV and IRR are two discounted cash flow methods used for evaluating investments or capital projects.
• NPV is is the dollar amount difference between the present value of discounted cash inflows less outflows over a specific period of time. If a project’s NPV is above zero, then it’s considered to be financially worthwhile.
• IRR estimates the profitability of potential investments using a percentage value rather than a dollar amount.
