Estimate how much house you can afford using income, existing debts, mortgage rate, down payment, property tax, insurance, HOA fees, and DTI limits.
Formula
Home affordability depends on income, existing monthly debt, estimated housing costs, down payment, interest rate, and debt-to-income limits. The calculator compares front-end and back-end DTI limits and uses the tighter monthly payment budget.
DTI limits
Lenders often review both housing costs and total monthly obligations. A lower DTI can make a home purchase more comfortable, while a higher DTI may leave less room for savings, emergencies, repairs, and other living costs.
Use cases
Use it before house hunting, comparing loan assumptions, planning a down payment, or checking whether a target home price fits your monthly budget.

Questions
A house affordability calculator estimates the maximum home price that may fit your income, debt payments, down payment, mortgage rate, loan term, property tax, insurance, HOA fees, and debt-to-income limits.
Debt-to-income ratio compares monthly debt obligations to monthly gross income. Front-end DTI focuses on housing costs, while back-end DTI includes housing plus other monthly debts.
No. The results are estimates only. Lenders may also consider credit score, employment history, assets, location, loan program, property type, and underwriting rules.
A higher down payment reduces the loan amount, which can lower the monthly payment and increase the home price that fits within the same DTI limit.
