How to Use This Home Affordability Calculator
Our free home affordability calculator helps you determine how much house you can comfortably afford based on your income, debts, and down payment. Understanding your budget before you start shopping prevents disappointment and helps you focus on homes within your price range.
The calculator uses the 28/36 rule — a standard lending guideline that suggests spending no more than 28% of gross monthly income on housing and no more than 36% on total debt. Enter your annual income, monthly debt payments, desired down payment, and expected interest rate to see your maximum affordable home price.
Factors that affect affordability include your income, credit score (which affects your interest rate), existing debts, down payment amount, property taxes, homeowners insurance, and HOA fees. This calculator accounts for all of these to give you a realistic picture of what you can afford.
As a first-time home buyer, you may qualify for special programs with lower down payment requirements and closing cost assistance. Use this calculator to understand your budget and start your home search with confidence.

Frequently Asked Questions about Home Affordability
How much house can I afford on a $50K salary?
Using the 28/36 rule, with a $50K annual salary you can afford monthly housing costs of about $1,167 (28% of gross monthly income). This typically translates to a home price of $200,000 to $250,000 depending on your down payment, interest rate, and other debts. Use our calculator for a personalized estimate.
What is the 28/36 rule for mortgage affordability?
The 28/36 rule states that you should spend no more than 28% of your gross monthly income on housing expenses (mortgage, taxes, insurance) and no more than 36% on total debt payments (housing plus credit cards, car loans, student loans). Lenders use this ratio to determine how much they're willing to lend you.
How does debt-to-income ratio affect home buying?
Your debt-to-income (DTI) ratio is the percentage of your gross monthly income that goes toward paying debts. Most lenders prefer a DTI of 43% or lower for a qualified mortgage. A lower DTI means you can qualify for a larger loan and better interest rates. Paying down debt before applying for a mortgage can significantly increase your buying power.
What credit score do I need to buy a house?
Credit score requirements vary by loan type: Conventional loans typically require 620+, FHA loans require 580+ (or 500 with 10% down), VA loans have no official minimum but most lenders want 620+, and USDA loans require 640+. Higher credit scores (740+) qualify for the best interest rates, potentially saving you thousands over the life of the loan.
How much should I save for a down payment?
While 20% down is traditional and eliminates PMI, many programs allow much less: Conventional loans as low as 3%, FHA loans at 3.5%, VA and USDA loans with 0% down. On a $300,000 home, 20% down is $60,000, while 3% down is just $9,000. Consider that a smaller down payment means higher monthly payments and PMI costs.
Can I buy a house with student loan debt?
Yes, many people buy homes while carrying student loans. Lenders look at your DTI ratio, so manageable student loan payments won't necessarily disqualify you. Income-driven repayment plans may be used to calculate your DTI. Focus on making payments on time to build credit and consider paying down higher balances to improve your debt ratio.
