How Much House Can I Afford? A Practical Budget Guide
A realistic home budget starts with the whole monthly cost, not the biggest mortgage a lender might approve.
Updated October 14, 2026 · Educational information
Start with the monthly payment that fits your life. Add principal and interest, property taxes, homeowners insurance, mortgage insurance if applicable, HOA dues, utilities, maintenance, and closing costs. Then compare that total with take-home income and your other goals.
Start with your monthly budget
List dependable take-home income and recurring obligations. Include debt payments, childcare, transportation, healthcare, savings, and irregular bills converted to monthly amounts. Decide what housing payment still leaves room for an emergency reserve and the life you want.
Estimate the full housing payment
A mortgage calculator often shows only principal and interest. Taxes, insurance, mortgage insurance, and HOA fees can change the total substantially. Local property taxes and insurance costs vary, so use current estimates for the specific property and ask about likely increases.
Factor in cash needed up front
Your down payment is only one part of cash to close. Budget for inspections, closing costs, moving, initial repairs, and a reserve after purchase. Avoid using every dollar of savings just to reach a target price.
Treat lender approval as one input
A lender evaluates its own underwriting requirements and may approve a payment that feels tight for your household. The CFPB recommends considering the full costs of ownership and your personal comfort. Compare written Loan Estimates from lenders and review rate, fees, cash to close, and payment.
Common questions
Should I use a lender’s maximum approval as my budget?
No. Approval is not the same as comfort. Include your full housing costs, other goals, and a cash reserve.
Does the affordability calculator include taxes and insurance?
No. The calculator estimates principal and interest capacity from the inputs. Add taxes, insurance, HOA dues, maintenance, and other costs separately.
