- PresentValue[ <Rate>, <Number of Periods>, <Payment>, <Future Value (optional)>, <Type (optional)> ]
- Returns the total amount of payments of an investment.
- <Rate> Interest rate per period.
- <Number of Periods> Total number of payments for the loan.
- <Payment> The amount paid in each period.
- <Future Value (optional)> A cash balance you want to attain after the last payment. If you do not enter a future value, it is assumed to be 0.
- <Type (optional)> Indicates when payments are due. If you do not enter a value or you enter 0 the payment is due at the end of the period. If you enter 1 it is due at the beginning of the period.
- Example:
PresentValue[ 12%/12, 4*12, -100, 5000, 0 ]yields a present value of 696.06.PresentValue[ 12%/12, 4*12, -100, 5000, 1 ]yields a present value of 734.07.Note: Make sure that you are consistent about the units you use for<Rate>and<Number of Periods>. If you make monthly payments on a four-year loan at an annual interest rate of 12 percent, use 12%/12 for rate and 4*12 for number of payments.
Note: For all arguments, cash paid out is represented by negative numbers and cash received by positive numbers.
Note: See also Payment, Periods, Rate and Future Value commands.
