How it works

Formula & explanation

House Affordability Calculator uses the following calculation:

MaxHousingPayment = (Income/12 × DTI%) − OtherDebt

This is a simplified model intended for planning and education. Real-world offers from lenders, institutions, or tax authorities may include additional fees, rules, or adjustments not reflected here.

FAQ

Frequently asked questions

What debt-to-income ratio do lenders typically allow?

Many conventional lenders cap total DTI around 36–43%, though some programs allow higher ratios with compensating factors.

Does this include property tax and insurance?

No, this is a simplified affordability estimate based on principal and interest; build in a buffer for taxes, insurance, and maintenance.

How much does a bigger down payment change affordability?

A larger down payment reduces the loan amount needed, which directly raises the home price you can afford at the same monthly payment.
