# CUMIPMT

The CUMIPMT function returns the cumulative interest paid between two periods.

### Syntax

CUMIPMT (Rate, Nper, PV, start\_period, end\_period, Type) - > Number 

### Arguments

<table><thead><tr><th width="159">Arguments</th><th width="147">Datatype</th><th>Description</th></tr></thead><tbody><tr><td>Rate</td><td>Number, Node reference</td><td>The interest rate per period.</td></tr><tr><td>Nper</td><td>Number</td><td>The total number of periods.</td></tr><tr><td>PV</td><td>Number</td><td>The present value of the loan.</td></tr><tr><td>start_period</td><td>Number</td><td>The first payment period.</td></tr><tr><td>end_period</td><td>Number</td><td>The last payment period.</td></tr><tr><td>Type</td><td>Number</td><td>Indicates when the payments are made. Type is zero if payments are made at the end of the period and non-zero if payments are made at the start of the period.</td></tr></tbody></table>

### Example

Consider a $10,000 loan at an annual rate of 10% that is to be paid off in 1.5 years. All payments are made at the beginning of the month. Calculate Cumulative Interest Payments for all periods.

To achieve this, the following formula should be written in the \[Cumulative Interest Payments] node:

<mark style="color:blue;">**`CUMIPMT`**</mark>**` ``(`**<mark style="color:purple;">**`[Rate]`**</mark>**`/12,`**<mark style="color:orange;">**`[Number of Years]`**</mark>**`*12,`**<mark style="color:red;">**`[Loan Amount]`**</mark>**`,1,`**<mark style="color:green;">**`[End Period]`**</mark>**`,1)`**
