The time value of money calculations can also be used to calculate the net present value of a series of cash flows, or of an investment plus a series of cash flows. Basically, the net present value calculation compares the value of a dollar today with the value of that dollar in the future, after taking rate of return and/or inflation into account. When evaluating an investment, it is desirable for the net present value to be greater than the amount invested; otherwise, there is no incentive to make that investment.
