=CUMPRINC(rate, nper, pv, start_period, end_period, type)


  • Rate: It is the rate of the required loan.
  • NPER: It is the number of payment periods.
  • PV: It is the present value.
  • Start_Period: First period to be used in the calculation.

  • Microsoft Excel stores dates as serial numbers . By default, January 1, 1900 is serial number 1 and corresponding dates have serial number greater than 1.
  • If Rate ≤ 0 and  nper ≤ 0, or pv ≤ 0, #NUM! error is displayed.
  • If start_period < 1, end_period < 1, or start_period > end_period, #NUM! error is displayed.
