This calculator works from monthly affordability toward purchase price. The U.S. CFPB recommends deciding what you want to spend first, then using principal-and-interest plus taxes, insurance, mortgage insurance, and escrow to understand the full payment.
"The result is a budget boundary, not a lender promise; for U.S. mortgages, confirm it with Loan Estimates before you shop seriously."
When lenders quote you, compare the official Loan Estimate line by line, not just the monthly payment.
Stress the rate
Run a higher-rate scenario before committing. Fixed-rate loans keep the rate steady, while ARM loans can change after the initial period.
Frequently Asked Questions
It starts with your total monthly housing budget, subtracts estimated taxes and insurance, then solves the fixed-rate amortization formula backward to estimate the largest loan principal you could support. The U.S. CFPB affordability guide describes the same idea: estimate the loan amount, then add your down payment to estimate an affordable home price.
Your lender may quote principal and interest separately from the total monthly payment. The CFPB explains that property taxes, homeowners insurance, mortgage insurance, and escrow can raise the total amount you must afford each month.
No. This is a planning calculator, not underwriting. Lenders also review income, credit, debts, loan type, reserves, property details, and closing costs. For U.S. mortgage offers, use the official CFPB Loan Estimate comparison tool.
A longer fixed-rate term usually supports a larger loan for the same monthly principal-and-interest payment, but total interest rises. A shorter term lowers lifetime interest but reduces the affordable loan amount. The U.S. CFPB fixed-rate vs adjustable-rate guide also explains why adjustable-rate loans can change later.
For U.S. mortgages, compare the calculator estimate with your Loan Estimate and Closing Disclosure before closing. The CFPB Closing Disclosure explainer highlights principal and interest, mortgage insurance, escrow, estimated taxes, insurance, and assessments.
