CUMPRINC formula explanation

  • 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 12 percent, use 12%/12 for rate and 4*12 for nper. If you make annual payments on the same loan, use 12% for rate and 4 for nper.
  • If rate ≤ 0, nper ≤ 0, or pv ≤ 0, CUMPRINC returns the #NUM! error value.
  • If start_period < 1, end_period < 1, or start_period > end_period, CUMPRINC returns the #NUM! error value.
  • If type is any number other than 0 or 1, CUMPRINC returns the #NUM! error value.
