Rate(PeriodCount, PeriodPayment, CurrentCost, FutureValue, Type[, Guess])
PeriodCount. The total number of payment periods in an investment.
PeriodPayment. Regular payment (once a period) that remains the same during the entire annuity term. Payments usually include primary payments and interest payments, but do not include taxes and charges.
CurrentCost. The present value, or the lump-sum amount that a series of future payments is worth now.
FutureValue. The required value of future cost or the remainder after the last payment.
Type. Selecting payment time. This parameter may take the following values:
0. Payment at the end of the period.
1. Payment at the beginning of the period.
Guess. Optional parameter. Expected interest rate. The default value is 0.01.
NOTE. To determine the parameter, specify either the parameter value or the cell address where it is located.
It returns the interest rate per period of a loan or an investment.
If the Rate function does not agree, try to use various values for the Guess parameter. Rate usually agrees if the Guess value is between the 0 and 1 numbers.
The Rate function is calculated using the iteration method and can generate a zero value or a number of values. If successive function results do not match the accuracy of 0.0000001 after 20 iterations have been completed, Rate will return an error.
