The NPV formula is a way of calculating the Net Present Value (NPV) of a series of cash flows based on a specified discount rate. The NPV formula can be very useful for financial analysis and financial modeling when determining the value of an investment (a company, a project, a cost-saving initiative, etc.). As shown in the analysis above, the net present value for the given cash flows at a discount rate of 10% is equal to $0. This means that with an initial investment of exactly $1,000,000, this series of cash flows will yield exactly 10%. As the required discount rates moves higher than 10%, the investment becomes less valuable. In this case, the formula for NPV can be broken out for each cash flow individually. For example, imagine a project that costs $1,000 and will provide three cash flows of $500, $300, and $800 over the next three years. Assume there is no salvage value at the end of the project and the required rate of return is 8%. Present value of $1, that is where r = interest rate; n = number of periods until. payment or receipt. The NPV of a sequence of cash flows takes as input the cash flows and a discount rate or discount curve and outputs a present value, which is the current fair price. The converse process in discounted cash flow (DCF) analysis takes a sequence of cash flows and a price as input and as output the discount rate, or internal rate of return (IRR) which would yield the given price as NPV. Discount Rates are the controlling value in NPV and DCF calculations. Discounting cashflows to achieve a Net Present Value (NPV) is not without problems but it has one great advantage it makes all the results directly comparable and it is transparent how you got there.

## Choose discount rate method for Net Present Value Net Present Value (NPV) is a financial analytical method that aggregates a series of discounted cash flows into present day values. It recognizes that, given a choice, a “rational” person would rather have a dollar, pound or Euro today rather than one year from now.

Discount rate: summary of The discount rate applied to cash flow is sometimes used to justify the discount rate for prepayment versus deferred payment. It used to be that a number in the range 10-15% was appropriate. With interest rates so very low, however, I can't see how a company can justify more than the 2-3% figure you quote. Interest rate used to calculate Net Present Value (NPV) The discount rate we are primarily interested in concerns the calculation of your business’ future cash flows based on your company’s net present value, or NPV. Your discount rate expresses the change in the value of money as it is invested in your business over time.
