Calculates the cumulative principal paid over a range of payment periods for an investment based on constantamount periodic payments and a constant interest rate.
Sample Usage
CUMPRINC(0.12,12,100,1,5,0)
CUMPRINC(A2,B2,C2,D2,E2,1)
Syntax
CUMPRINC(rate, number_of_periods, present_value, first_period, last_period, end_or_beginning)

rate
 The interest rate. 
number_of_periods
 The number of payments to be made. 
present_value
 The current value of the annuity. 
first_period
 The number of the payment period to begin the cumulative calculation.first_period
must be greater than or equal to1
.

last_period
 The number of the payment period to end the cumulative calculation.last_period
must be greater thanfirst_period
.

end_or_beginning
 Whether payments are due at the end (0
) or beginning (1
) of each period.
Notes
 Ensure that consistent units are used for
rate
andnumber_of_periods
. For example, a car loan for 36 months may be paid monthly, in which case the annual percentage rate should be divided by 12 and the number of payments is 36. On the other hand, a different type of loan of the same length might be paid quarterly, in which case the annual percentage rate should be divided by 4 and the number of payments would be 12.
