- Payment[ <Rate>, <Number of Periods>, <Present Value>, <Future Value (optional)>, <Type (optional)> ]
- Calculates the payment for a loan based on constant payments and a constant interest rate.
- <Rate> Interest rate per period.
- <Number of Periods> Total number of payments for the loan.
- <Present Value> Total amount that a series of future payments is worth now.
- <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:
Payment[6%/12, 10, 10000, 0,1]
yields a monthly payment for a loan of -1022.59.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 6 percent, use 6%/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 Rate, Periods, Present Value and Future Value commands.
