RATE(NoOfPeriods, Payment, PresentValue, FutureValue, Type, Guess)

where, $NoOfPeriods$ represents total number of payment periods
$Payment$ represents the payment made for each period
$PresentValue$ represents the remaining value of payment to be done
$FutureValue$ represents the balance value to attain after last payment is made
$Type$ represents the payments due
$Guess$ is the guess value for what rate will be

RATE() calculates the interest rate per period for a year.

Description

RATE is calculated by iteration and can have zero or more solutions.
$Payment$ includes principal value and the interest amount. If omitted, $FutureValue$ is required.
$FutureValue$ , $Type$ and $Guess$ are optional.
If $FutureValue$ is omitted, Calci assumes it to be zero(0).
$Type$ can be represented as '1' or '0'.

Type	Payments Due
0 or omitted	At the end of the period
1	At the beginning of the period

If $Guess$ is omitted, Calci assumes it to be 10%.

Examples

Consider the following example that shows the use of RATE function:

2	8
-50	-100
2000	50000
0	0
1	0
12%

=RATE(A1*12,A2,A3,A4,A5,A6) displays monthly rate of loan -4.01% as a result.
=RATE(B1*12,B2,B3,B4,B5) displays monthly rate of loan -2.77% as a result.
=RATE(B1*12,B2,B3,B4,B5)*12 displays annual rate of loan -0.33263515005213806 as a result.
