Returns the cumulative principal paid on a loan between start_period and end_period.
If this function is not available, and returns the #NAME? error, install and load the Analysis ToolPak add-in.
- On the Tools menu, click Add-Ins.
- In the Add-Ins available list, select the Analysis ToolPak box, and then click OK.
- If necessary, follow the instructions in the setup program.
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.
||Payment at the end of the period
||Payment at the beginning of the period
- 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.
- Nper, start_period, end_period, and type are truncated to integers.
- 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.

||Interest rate per annum
||Term in years
||The total principal paid in the second year of payments, periods 13 through 24 (-934.1071)
||The principal paid in a single payment in the first month (-68.27827)
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.
