How to Create a Mortgage Calculator in Google Sheets from Scratch

Creating a mortgage calculator in Google Sheets should not take more than a couple of minutes with the following step-by-step guide.

Have a look at the following image,

It is a simple mortgage calculator with two tables. The first gets the inputs from the users, and the second one auto-calculates various things using those inputs.

Before we jump into the actual steps, let us understand one crucial function that we are going to use to create our mortgage calculator.

Explained: The PMT Function in Google Sheets

This formula is helpful in case of any long-term payment situations such as mortgage, home, or car loan. It calculates EMI (Equated Monthly Installments) over a given period.

Here’s the general syntax for the function,

There are five different arguments in the formula. You need to replace them with the proper information as follows:

  • rate” – It represents the rate of interest for the loan
  • number_of_periods” – The total number of payments that need to be done between the given loan period
  • present_value” – Here, you need to enter the exact principal amount during the first month. It is also called the current value of the annuity
  • future_value” – It is an optional argument where you need to specify the remaining amount after the final payment
  • end_or_beginning” – This is another optional argument in the formula with a default value of 0. It means the payments will done at the end of each period

You can either enter the values manually or provide the cell references in the place of the above arguments.

Now, without any further ado, let’s use this formula to create a mortgage calculator.

STEP #1 – Add the Header

The header is a crucial component of any template. It allows us to add titles or specific information that adds a personal touch to a template.

Open a new Google Sheet by clicking here

  • Create a new Google spreadsheet by clicking here
  • Select the entire first row
  • Increase the height as shown below
  • Next, select all the cells from A1 to D1
  • Hover to the toolbar section that sits below the main menu
  • Click the “Merge cells” icon as shown in the above image
  • Type “Mortgage Calculator
  • Increase the font size to 20
  • Make the font bold
  • Change the background color to green (Hex Code – #00ac46)
  • Change the font color to white
  • Align the text to the middle

Here’s how our header should look after following the above steps.

STEP #2 – Create Loan Values Table

In this step, we will learn to add a table to Google Sheets with proper formatting. It will be used to add your loan information to the calculator.

The table should include the following fields,

  • Loan Amount
  • Annual Interest Rate
  • Term in Years
  • Number of Payments per Year
  • Extra Optional Monthly Payment

Let’s begin,

  • Select the cell “B3
  • Type “Loan Amount
  • Now, repeat the above steps and complete the table as shown below,
  • Select the entire column B
  • Increase the width
  • Now, select the table range “B3:C7
  • Go to the toolbar and click the “Borders” icon
  • Change the border color to light gray
  • Again, click the Border icon from the toolbar section and choose “All borders”

Our table is ready. But we need to format cells so that whenever we enter the values, they are reflected as currency or percentage.

  • Select the cell “C3” and “C7
  • Hover to the main menu and click on “Format” tab
  • Choose the “Number” option from the popup
  • Next, select the “Currency” from the list

Now, whatever values entered in the cells C3 and C7 will be displayed as currency.

Similarly, let’s format the cell C4 so that it will be reflected as a percentage.

  • Select the cell “C4
  • Hover to the main menu and click on the “Format” tab
  • Next, choose the “Number” option followed by the “Percentage” from the list, as shown in the following image,

With these steps, the Loan Values table is all done.

STEP #3 – Create Loan Summary Table

Here, we will be using various formulas in Google Sheets to calculate the following things automatically,

  • Monthly Installment
  • Total Number of Payments
  • Total Payment
  • Total Interest Cost

We will use the SUM and PMT functions discussed earlier in this section.

  • Select the cell “B10
  • Type “Monthly Installment
  • Next, complete the table as shown below,
  • Select the range “B10:C13
  • Hover to the toolbar section and click on the “Borders” icon
  • Then, select “All borders” from the available options

The table is ready; now, let us use the formulas. We will start with calculating the monthly installment amount.

  • Click on the cell “C10
  • Type “=pmt
  • Select the first option from the popup
  • Replace the rate argument with “C4/12
    (Here, the C4 cell contains the annual interest rate)
  • Press “,” to move to the next argument of the PMT function
  • Put “C5*12” in the place of the number_of_periods argument
    (The cell C5 contains the term in years or the period required to pay off the loan completely)
  • Press “,” on your keyboard
  • Replace present_value argument with “-C3
    (The cell C3 includes the total loan amount)
  • Complete the parentheses using “)” on your keyboard

Here’s how the final formula looks,

Next, the formula to calculate the Total Number of Payments is as follows.

You need to enter the above formula in cell C11.

To calculate the Total Amount, we will simply multiply the Monthly installments by the Total Number of Payments. The formula will be as follows,

  • Cell C10 includes Monthly Installment
  • The cell C11 includes the Total Number of Payments

Finally, to calculate the total interest cost, we need to subtract the Loan Amount from the Total Amount that we paid during the given period.

The formula will be,

  • Cell C12 includes the Total Amount paid over time
  • Cell C3 includes Loan Amount

Our formulas for the Loan Summary Table are shown in the following image.

STEP #4 – Formatting the Loan Values and Loan Summary table

The Mortgage Calculate is ready. Now is the time to make it professional and aesthetically pleasing.

You need to use the toolbar section to format the tables.

Based on our Google Sheets knowledge and expertise, we have formatted the tables as shown below.
