CUMPRINC

## Category:

Financial Analysis

## Summary:

Calculates a cumulative principal payment.

## Syntax:

CUMPRINC(Rate; NPer; PV; S; E; Type)

## Returns:

Returns the cumulative interest paid for an investment period with a constant interest rate.

## Arguments:

Rate is a positive real number or a reference to the cell containing that number which is the periodic interest rate.

NPer is a positive real number or a reference to the cell containing that number which is the payment period with the total number of periods. Nper can also be a non-integer value.

PV is a positive real number or a reference to the cell containing that number which is the current value in the sequence of payments.

S is a positive real number or a reference to the cell containing that number which is the first period.

E is a positive real number or a reference to the cell containing that number which is the last period.

Type is the due date of the payment at the beginning or end of each period.

Type Maturity Date
0 due at the end
1 due at the beginning
• If Rate, NPer or PV. are less than or equal to 0 then the function will return an error value.
• If S or E are non-integer values then the function uses their floor values, i.e. they are truncated to integers.
• If S(after truncation) is less than 1 or greater than E(after truncation) then the function returns an error value.
• If E(after truncation) is greater than NPer then the function returns an error value.
• If Type is anything accept 0 or 1, then the function returns an error value.

• The formula for CUMPRINC is:

where Rate is Rate, Start is S, End is E, Periods is NPer, Value is PV and Type is Type.

## Examples:

Formula Description Returns
=CUMPRINC(5.5%/12;36;15000;10;18;0) The function calculates the payoff amounts if the yearly interest rate is 5.5% for 36 months. The cash value is 15,000 currency units. The payoff amount is calculated between the 10th and 18th period. The due date is at the end of the period. -₹3,669.74 (currency units)
=CUMPRINC(5.5%/12;36;15000;10;18;1) The function calculates the payoff amounts if the yearly interest rate is 5.5% for 36 months. The cash value is 15,000 currency units. The payoff amount is calculated between the 10th and 18th period. The due date is at the beginning of each period. -3,652.99 (currency units)
=CUMPRINC(5.5%/12;36;15000;10;18;2) The function returns an error for any value of Type except for 0 or 1. Err:502
=CUMPRINC(5.5%/12;36;15000;0.9;18;1) The function returns an error since S is less than 1. Err:502
