## Computational Notes:

The present value is computed using the following formula:

PV = P * [(1 - (1 + r)^-n) / r]

Where:

PV = Present Value

P = Payment

r = Discount Rate / 100

n = Number Payments

Adjust the discount rate to reflect the interval between payments which typically are annual, semiannual, quarterly or monthly. For example, for a 6% annual discount rate, enter 6 for an annual interval. Enter 3 for a semiannual interval. Enter 1.5 for a quarterly interval. Enter .5 for a monthly interval.

The discount rate is the same for all payment periods.
