What is HELOC?

HELOC stands for Home Equity Line of Credit. It is a special type of loan based on the equity of one’s home mortgage. Also, it is different from other home equity loans like home loans and cash refinances. Below is the formula to calculate HELOC payments.

HELOC Payment =  (CHB × RATE) × ( (1 + RATE)^(12 × RP)) / ( (1 + RATE)^(12 × RP) – 1 )

Where,

CHB = Current HELOC Balance (Principal)

RP= Repayment Periods in Years

RATE= Monthly Interest Rate

Step-by-Step Procedures to Make HELOC Payment Calculator Using Principal and Interest in Excel

We have taken a concise excel dataset to explain the steps clearly. The dataset has approximately 7 rows and 2 columns. Initially, we formatted all the cells containing dollar values in Accounting format and all the percentage values in % format. For all the datasets, we have 2 unique columns which are Property and Value. Although we may vary the number of columns later on if that is needed.

Step 1: Setting Up Data Table

In this first step, we will create the data table to insert the necessary parameters and format them properly.

• First, create a data table following the below format and insert the necessary parameters in the left column. Make sure to make the table headers bold.

Step 2: Entering Input Values

Now, we have to insert the input values for which we want to calculate our HELOC payments. Let us see how to do that.
