Free Home Mortgage Calculator Spreadsheet Template for Google Sheets & Excel
Three inputs - the amount borrowed, the annual rate, the term - and five results under them: the monthly principal and interest, everything paid across the term, the interest inside that total, the rate expressed per month and the number of payments the term contains. The Free Home Mortgage Calculator spreadsheet template keeps all of it on one working sheet with a currency dropdown. Google Sheets or Excel, one file. No macros, no VBA, no sign-up.
The FinancialAha Free Home Mortgage Calculator Spreadsheet Template is a one-sheet workbook for Google Sheets and Excel, with a How to Use guide on a second tab. It works as a Free Home Mortgage Calculator Excel template and a Free Home Mortgage Calculator Google Sheets template from the same download. This Free Home Mortgage Calculator spreadsheet template answers the borrowing question: at this amount, this rate and this term, what the monthly payment is and what the loan costs in interest across its life. No macros, no VBA, no sign-up.
Inside the workbook
What's inside the FinancialAha Free Home Mortgage Calculator spreadsheet template
The FinancialAha Free Home Mortgage Calculator Spreadsheet Template runs on one working sheet, with the instructions on a tab of their own. It works in both Microsoft Excel and Google Sheets and here is what the Free Home Mortgage Calculator spreadsheet holds.
01of 01
Mortgage
The single working sheet, and the whole template. Three figures go in - the amount borrowed, the rate and the term - and five come back: the rate per month, how many payments the term contains, the monthly payment, everything paid by the end, and the interest inside that total. The payment here is the loan itself, principal and interest, and nothing else: property tax, insurance and any mortgage insurance sit outside it, so the figure is what you owe the lender rather than what leaves your account each month.

Included guide
How to Use
A step-by-step guide on its own tab, covering setup, how to replace the sample values, and how to change the currency. Because it ships inside the file, the instructions travel with the template wherever it is opened.

FinancialAha Home Mortgage Calculator spreadsheet template: Free, Essentials, and Ultimate compared
The FinancialAha Free Home Mortgage Calculator Spreadsheet Template covers one working sheet and answers what the loan costs. Its payment is principal and interest alone, which is the honest limit of the Free build: there is no deposit field, no property tax or insurance, and no schedule, so it tells you what you owe the lender rather than what a month of ownership costs. The Essentials Home Mortgage Calculator Spreadsheet Template for Google Sheets and Excel takes the price and a deposit share, adds tax and insurance to reach a full monthly figure, and lays out a dated schedule with extra payments and a payoff date. The Ultimate Home Mortgage Calculator Spreadsheet Template compares three loan structures side by side, gives extra payments a sheet of their own, and adds refinance modelling.
Notes on working in the Free Home Mortgage Calculator spreadsheet template
The payment here is principal and interest. Tax, insurance and any mortgage insurance sit outside it.
A rate of zero returns the loan spread evenly across the payments rather than an error.
The rate is applied as fixed for the whole term, so a variable-rate loan is only approximated.
The monthly rate and payment count come back as results of their own.
The dropdown beside the title relabels the money fields. It changes the label and nothing else.
How the Home Mortgage Calculator template works
The borrowing question: at this amount, this rate and this term, the monthly principal and interest, everything paid across the term, and the interest inside it.
When this template helps
01
You have a loan amount and a rate in mind and want the monthly principal and interest before you talk to anyone about it.
02
You want the cost of the borrowing as well as the monthly figure. Total interest is on a line of its own, apart from total paid.
03
You are weighing a thirty-year term against a twenty-year one and want both payments in front of you.
04
A quoted rate has moved and you want the payment and the interest rerun without redoing the arithmetic.
Tips to get the most out of it
Enter the amount being borrowed rather than the purchase price, since the deposit is not modelled here.
Total interest read beside total paid is what separates the cost of the house from the cost of borrowing for it.
Because tax and insurance sit outside the payment, the real monthly commitment is higher than the figure returned.
Common mistakes to avoid
Entering the purchase price where the loan amount belongs, which overstates the payment by the size of the deposit.
Reading the monthly figure as a housing cost. It covers the loan only.
Entering a monthly rate where the annual one is asked for.
How to Use the Free Home Mortgage Calculator Spreadsheet Template
1
Enter the loan
Put in the amount actually being borrowed, after any deposit.
2
Add rate and term
Enter the annual rate and how many years the loan runs.
3
Read the payment
The monthly principal and interest figure follows from those three inputs.
4
Check the interest
Total paid and total interest sit alongside, separating repayment from the cost of borrowing.

Frequently Asked Questions
What is the difference between the free, Essentials, and Ultimate Free Home Mortgage Calculator spreadsheet template?
Free is a single-sheet starter template with sample data and a How to Use guide. Essentials ($19) is the fuller build - more capacity, more detail, and more worked out for you rather than typed. Ultimate ($29) goes further again, usually six working sheets, giving each part of the template its own sheet and adding deeper reporting on top. What each tier holds differs by template - the comparison table on every template page lists it exactly.
Which Free Home Mortgage Calculator spreadsheet template should I download?
Upgrade to Essentials if you want a dashboard with charts, more categories, larger capacity, and a more polished spreadsheet for ongoing use. The Free version is a good fit for one-off planning or trying out the layout.
Can I upgrade the Free Home Mortgage Calculator spreadsheet template later?
Essentials is a one-time $19 purchase with no subscription. It typically adds a full dashboard, 30-50% more categories or rows than the Free version, and richer formulas. Most buyers upgrade after using the Free version for a few weeks and hitting its limits.
Is the FinancialAha Free Home Mortgage Calculator Spreadsheet Template a Google Sheets template?
Yes. Upload the file to Drive and choose "Open with Google Sheets". Nothing needs rewriting in the Free Home Mortgage Calculator Google Sheets template, and the currency dropdown still relabels the money fields.
Is the FinancialAha Free Home Mortgage Calculator Spreadsheet Template an Excel template?
Yes. The download is a plain .xlsx, so the Free Home Mortgage Calculator Excel template opens directly in Excel with no import step. There are no macros and no VBA, so it opens without a security warning.
Will the Free Home Mortgage Calculator spreadsheet Excel file open in older versions of Excel?
Yes. The Free Home Mortgage Calculator spreadsheet Excel workbook ships as a plain .xlsx, so it opens identically in current Excel and in builds that predate dynamic arrays.
Does the FinancialAha Free Home Mortgage Calculator Spreadsheet Template include property tax and insurance?
No. The payment it returns is principal and interest - what you owe the lender - rather than what leaves your account each month. Property tax, insurance and any mortgage insurance are outside it, and the Essentials build is the one that folds them in to reach a full monthly figure.
Should I enter the purchase price or the loan amount in the Free Home Mortgage Calculator spreadsheet?
The loan amount. There is no deposit field in this build, so the figure you enter is what is actually being borrowed. The Essentials build takes the price and a deposit share instead and works the loan out from them.
Does the Free Home Mortgage Calculator spreadsheet handle a variable rate?
Only approximately. The rate is applied as fixed for the whole term, so a loan whose rate changes part way is modelled as though it does not.
Is the Free Home Mortgage Calculator spreadsheet template safe to download?
Yes. No macros, no sign-up, no tracking. The file is a plain .xlsx that opens directly in Excel or Google Sheets.
How do I open the Free Home Mortgage Calculator spreadsheet template in Google Sheets?
Upload the .xlsx file to Google Drive, then open it with Google Sheets. All formulas and formatting will be preserved.
