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 and if you enter 1 at the beginning.

Example:

Periods[10%/12, -200, -400, 10000] yields a number of payments of 39.98 .

Note: If you make monthly payments on an annual interest rate of 10 percent, use 10%/12 for <Rate>.
