- Periods[ <Rate>, <Payment>, <Present Value>, <Future Value (optional)>, <Type (optional)> ]
- Returns the number of periods for an annuity based on periodic, fixed payments and a fixed interest rate.
- <Rate> Interest rate per period.
- <Payment> The amount paid in each period.
- <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:
Periods[10%/12, -200, -400, 10000]
yields a number of payments of 39.98.Periods[10%/12, -200, -400, 10000, 1]
yields a number of payments of 39.7.Note: If you make monthly payments on an annual interest rate of 10 percent, use 10%/12 for<Rate>
.
Note: For all arguments, cash paid out is represented by negative numbers and cash received by positive numbers.
Note: See also Payment, Rate, Present Value and Future Value commands.
