TrueAffordMortgage Calculator
A mortgage calculator with nothing to sell you
Every other mortgage calculator online is owned by a company that makes money when you apply for a loan. This one isn't selling leads, so there's no incentive to show you a bigger number than you can actually afford.

Frequently asked questions
How is this different from a bank's mortgage calculator?
A bank's calculator shows what you'd qualify for. This one shows that number too, but sits it next to what your household can actually sustain once real monthly expenses are accounted for — the two are often different, and the gap matters.
Does the payment include taxes and insurance?
Yes — principal, interest, property tax (state-specific, not a national average), homeowner's insurance, PMI when your down payment is under 20%, HOA dues if you have them, and a maintenance reserve. Every line is broken out separately and editable.
Can I share my results with someone?
Yes — every input you change updates the page's URL automatically. Copy the link at the bottom of the results and send it to anyone; it opens to the exact same numbers, computed fresh, not a screenshot.
What credit score assumptions does this use?
Pick your credit band and the calculator applies a realistic default interest rate and PMI cost for that tier, both documented on the methodology page. You can override the interest rate directly if you have a specific quote.
Is a mortgage affordability calculator the same as a home loan affordability calculator?
Yes — 'mortgage affordability calculator' and 'home loan affordability calculator' describe the same thing: working out the monthly payment and the price a home loan supports. This one adds the state-specific tax and insurance data, and the lender-approval-vs-sustainable comparison, that most versions of this tool leave out.
