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)`**
