The Excel CUMPRINC function is a financial function that returns the cumulative principal paid on a loan between a start period and an end period. You can use CUMPRINC to calculate and verify the total principal paid on a loan, or the principal paid between any two payment periods.

**Syntax**:=CUMPRINC (rate, nper, pv, start_period, end_period, type)

The CUMPRINC function syntax has the following arguments:

**Rate**Required. The interest rate.**Nper**Required. The total number of payment periods.**Pv**Required. The present value.**Start_period**Required. The first period in the calculation. Payment periods are numbered beginning with 1.**End_period**Required. The last period in the calculation.**Type**Required. The timing of the payment.

Type |
Timing |
---|---|

0 (zero) | Payment at the end of the period |

1 | Payment at the beginning of the period |

**Example**: Let’s look at some Excel CUMPRINC function examples and explore how to use the CUMPRINC function as a worksheet function in Microsoft Excel:

**Syntax**: =CUMPRINC(B1/12,B2*12,B3,1,1,0)

**Result**:

- The payments are made monthly, so we have converted the annual interest rate of 0.08 into a monthly rate (=0.08/12), and the number of years into months (=40*12).
- The calculated payments are negative values, as they represents outgoing payments (for the individual taking out the loan).

Based on the Excel spreadsheet above, the following CUMPRINC examples would return:

**Syntax**: =CUMPRINC(B1/12,B2*12,B3,1,12,0)**Result**: -713.2568371

**Syntax**: =CUMPRINC(B1/12,B2*12,B3,13,24,0)**Result**: -772.4568028

**Syntax**: =CUMPRINC(B1/12,B2*12,B3,25,36,0)**Result**: -836.5703365

**Syntax**: =CUMPRINC(B1/12,B2*12,B3,37,48,0)**Result**: -906.0052619

**Syntax**: =CUMPRINC(B1/12,B2*12,B3,49,60,0)**Result**: -981.2032518

**Note**:

- #NUM! error occurs in the following scenarios:
- When the given start_period or end_period is less than or equal to zero.
- When the given start_period is greater than the end_period.
- When any of the given arguments – rate, nper, or PV – is less than or equal to zero.
- The argument type is not equal to 0 or 1.

- #VALUE! error – Occurs when any of the given arguments is a non-numeric value or is not recognized as a numeric value by Excel.
