CUMPRINC

**Syntax:** **CUMPRINC( R, N, P, S, E, T)**

*R* = Rate, a numeric expression

*N* = Number of payments, an integer 0

*P* = Present value

*S* = Starting period in calculation

*E* = Ending period in calculation

*T* = (Optional) timing of the payment:

0 | payment is made at the end of the period |

1 | payment is made at the beginning of the period |

**CUMPRINC** returns the cumulative principal paid between *S*
(the start) and *E* (the end) on a loan.

Make sure that you are consistent about the units used
for specifying *R* and *N*. (For example, for a 4-year loan
with 10% annual interest rate, use 10%/12 for *R* and 4*12
for *N*)

**Example:**

**CUMPRINC**(9.5%/12, 30*12, 100000, 1, 12, 0) = 616.64

**Excel function:** *N/A*
