Free Home Affordability Calculator Spreadsheet Template for Google Sheets & Excel
Six inputs on one sheet: income, existing debt payments, deposit, rate, term and the debt-to-income limit you want to work to. The Free Home Affordability Calculator spreadsheet template takes the debt payments off the ceiling first, then returns the mortgage payment that limit allows, the loan that payment supports at your rate and term, and the price it reaches. Principal and interest only. Google Sheets or Excel, one file. No macros, no VBA, no sign-up.
The FinancialAha Free Home Affordability 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 Affordability Calculator Excel template and a Free Home Affordability Calculator Google Sheets template from the same download. Six figures go in - income, existing debt payments, the down payment, the rate, the term and the debt-to-income limit you want to work to - and this Free Home Affordability Calculator spreadsheet template returns the mortgage payment that limit allows, the loan it supports and the price it reaches with your deposit added. No macros, no VBA, no sign-up.
Inside the workbook
What's inside the FinancialAha Free Home Affordability Calculator spreadsheet template
The FinancialAha Free Home Affordability Calculator Spreadsheet Template runs on a single 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 Affordability Calculator spreadsheet holds.
01of 01
Affordability
Six inputs on the left, three results on the right. The chain is short and worth understanding: your monthly income multiplied by the debt-to-income limit gives a ceiling, your existing debt payments come off it, and what remains is the mortgage payment. That payment amortised at the rate and term you entered is the loan, and the loan plus your down payment is the price.
The limit is an input rather than a rule the sheet asserts. Lenders work to their own figures and those figures move, so the sensible use of this sheet is to run the number your lender has quoted rather than to treat any percentage as a standard.
One thing to hold onto: this build works in principal and interest only. Property tax, home insurance and any association fees are real monthly costs that sit on top of the figure it returns, which means the price it gives is higher than what the same monthly ceiling would actually carry. Those three are on the Essentials build, and each takes a share of the payment that the free build does not account for.
Two entries that break other calculators are handled. A zero rate returns a real figure, and debt payments large enough to swallow the whole allowance return "Debts exceed the limit" rather than a negative house price - which is the answer, not an error.

Opening the Free Home Affordability Calculator spreadsheet Excel file
Nothing in the Free Home Affordability Calculator Excel template is version-specific, so this Free Home Affordability Calculator spreadsheet Excel workbook behaves identically in Excel on Windows, Excel on Mac, and older builds.
The FinancialAha Free Home Affordability Calculator Spreadsheet Template works in principal and interest: it takes one debt-to-income limit, subtracts your existing debt payments and turns what is left into a loan and a price. The Essentials Home Affordability Calculator Spreadsheet Template for Google Sheets and Excel puts the rest of the monthly bill into the same calculation - property tax as a rate on the price, annual insurance and any association fees - so the payment it solves for is the one a lender would actually look at. It applies a front-end limit as well as a back-end one and takes the lower of the two, reports the down payment as a share of the price it reaches, and shows the same figure at eighty and ninety percent of the maximum.
Notes on working in the Free Home Affordability Calculator spreadsheet template
The chain runs: monthly income times the limit, less existing debt payments, gives the mortgage payment; that payment amortised at your rate and term gives the loan; the loan plus your deposit gives the price.
Debt payments large enough to swallow the allowance return a message rather than a negative figure.
A rate of zero is handled - the loan becomes the payment spread across the term.
This build is principal and interest only. Property tax, insurance and association fees sit on top of what it returns.
The debt-to-income limit is an input rather than a rule the sheet asserts.
The dropdown beside the title relabels the money rows. It changes the label and nothing else.
How the Home Affordability Calculator template works
The Free Home Affordability Calculator Spreadsheet Template runs a short chain: your monthly income times the debt-to-income limit gives a ceiling, your existing debt payments come off it, what remains is the mortgage payment, that payment amortised at your rate and term is the loan, and the loan plus your deposit is the price. The limit is an input rather than a rule the sheet asserts, so the useful move is to run the figure your lender has quoted. One thing to hold onto: this build works in principal and interest only. Property tax, home insurance and any association fees are real monthly costs that sit on top of the payment it returns, which means the price it gives is higher than that same ceiling would actually carry. Those three are folded into the Essentials build.
When this template helps
01
You want a ballpark price before talking to a lender.
02
You want to see what clearing a car loan does to the number.
03
You are comparing what different deposits reach at the same income.
04
A rate has moved and you want to know what it costs you in price.
Tips to get the most out of it
Running the figure your lender has quoted is what makes the answer theirs rather than the template's.
Existing debt payments come off the ceiling before anything else, so clearing a car loan moves the price by more than the payment itself.
Because tax and insurance sit outside the payment, the price it returns is higher than the same monthly ceiling would actually carry.
Common mistakes to avoid
Reading the price as what you can carry. Tax and insurance are not in it.
Entering net income where the gross figure belongs - a debt-to-income limit is measured before tax.
Leaving out a debt payment that is ending soon, or including one that is not.
Reading the limit as a lender's answer. It is whatever figure you put in the cell.

Frequently Asked Questions
What is the difference between the free and Essentials Free Home Affordability 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. This template has no Ultimate build. What each tier holds differs by template - the comparison table on every template page lists it exactly.
Which Free Home Affordability 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 Affordability 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.

Yes. Upload the file to Drive and choose "Open with Google Sheets". Nothing needs rewriting in the Free Home Affordability Calculator Google Sheets template, and the results recalculate exactly as they do in Excel.

No. This build works in principal and interest only, so tax, insurance and any association fees sit on top of the payment it returns - which means the price it gives is higher than the same monthly ceiling would actually carry. The Essentials build folds all three into the calculation.
Where does the debt-to-income limit come from in the Free Home Affordability Calculator spreadsheet?
You. It is an input rather than a rule the sheet asserts, because lenders work to their own figures and those figures move. Running the number your lender has quoted is more useful than treating any percentage as a standard.
What happens in the Free Home Affordability Calculator spreadsheet if my debt payments are too high?
