CUMPRINC

Returns the cumulative principal paid on a loan between start_period and end_period.

Syntax

CUMPRINC(<rate>, <nper>, <pv>, <start_period>, <end_period>, <type>)


Parameters

Term Definition
rate The interest rate.
nper The total number of payment periods.
pv The present value.
start_period The first period in the calculation. Must be between 1 and end_period (inclusive).
end_period The last period in the calculation. Must be between start_period and nper (inclusive).
type The timing of the payment. The accepted values are listed below this table.

The type parameter accepts the following values:

Type Timing
0 (zero) Payment at the end of the period
1 Payment at the beginning of the period

Return Value

The cumulative principal paid in the specified period.

Remarks

• Make sure that you are consistent about the units you use for specifying rate and nper. If you make monthly payments on a four-year loan at an annual interest rate of 10 percent, use 0.1/12 for rate and 4*12 for nper. If you make annual payments on the same loan, use 0.1 for rate and 4 for nper.

• start_period, end_period, and type are rounded to the nearest integer.

• An error is returned if:

• rate ≤ 0.
• nper < 1.
• pv ≤ 0.
• start_period < 1 or start_period > end_period.
• end_period < start_period or end_period > nper.
• type is any number other than 0 or 1.
• This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
