RATE - Daxplained

RATE is a DAX function that returns the interest rate per period of an annuity, calculated by iteration and capable of handling multiple solutions.

Syntax

RATE(
   Nper,
   Pmt,
   Pv,
   Fv,
   Type,
   Guess
)

Argument	Properties	Description
Nper		The total number of payment periods in an annuity.
Pmt		The payment made each period, which cannot change over the life of the annuity. Typically, pmt includes principal and interest but no other fees or taxes.
Pv		The present value, or the total amount that a series of future payments is worth now.
Fv	Optional	The future value, or a cash balance you want to attain after the last payment is made. If fv is omitted, it is assumed to be 0 (the future value of a loan, for example, is 0).
Type	Optional	The number 0 or 1, which indicates when payments are due.
Guess	Optional	Your guess for what the rate will be. If guess is omitted, it is assumed to be 10%.

The interest rate per period.

Make sure that you are consistent about the units you use for specifying guess and nper. If you make monthly payments on a four-year loan at 12 percent annual interest, use 0.12/12 for guess and 4*12 for nper. If you make annual payments on the same loan, use 0.12 for guess and 4 for nper.
type is rounded to the nearest integer.
An error is returned if:
- nper ≤ 0.
- RATE does not converge to within 0.0000001 after 20 iterations
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

The following DAX query:

EVALUATE
{
  RATE(4*12, -200, 8000)
}

Returns the monthly rate of the loan using the terms specified above.

[Value]
0.00770147248820137

The following DAX query:

EVALUATE
{
  RATE(4*12, -200, 8000) * 12
}

Returns the annual rate of the loan using the terms specified above.

[Value]
0.0924176698584164
