Syntax

CUMIPMT(rate,nper,pv,start_period,end_period,type)

Rate     is the interest rate.

Nper     is the total number of payment periods.

Pv     is the present value.

Start_period     is the first period in the calculation. Payment periods are numbered beginning with 1.

End_period     is the last period in the calculation.

Type     is the timing of the payment.

Type Timing
0 (zero) Payment at the end of the period
1 Payment at the beginning of the 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 10%/12 for rate and 4*12 for nper. If you make annual payments on the same loan, use 10% for rate and 4 for nper.
• Nper, start_period, end_period, and type are truncated to integers.
• If rate ≤ 0, nper ≤ 0, or pv ≤ 0, CUMIPMT returns the #NUM! error value.
• If start_period < 1, end_period < 1, or start_period > end_period, CUMIPMT returns the #NUM! error value.
• If type is any number other than 0 or 1, CUMIPMT returns the #NUM! error value.

Formula Description (Result)
=CUMIPMT(A2/12,A3*12,A4,13,24,0) Total interest paid in the second year of payments, periods 13 through 24 (-11135.23)
=CUMIPMT(A2/12,A3*12,A4,1,1,0) Interest paid in a single payment in the first month (-937.50)

Note   The interest rate is divided by 12 to get a monthly rate. The years the money is paid out is multiplied by 12 to get the number of payments.
