Determine How Much House You Can Realistically Afford
Our Home Affordability Calculator helps you estimate a realistic home price based on your income, monthly debts, and down payment, ensuring you can comfortably manage your mortgage.
What is a Home Affordability Calculator?
A Home Affordability Calculator is a financial tool that helps potential homebuyers determine a reasonable price range for a new home based on their individual financial situation. It analyzes your gross income, recurring monthly debts (like car loans and student loans), and your saved down payment to calculate the maximum mortgage you can likely qualify for and, consequently, the total home value you can afford. It provides a crucial reality check before you start home shopping.
How It Works: The 28/36 Rule
This calculator is based on a common lending guideline known as the 28/36 rule for debt-to-income (DTI) ratios:
1. Max Housing Cost (Front-End DTI) = Gross Monthly Income × 0.28
2. Max Total Debt (Back-End DTI) = Gross Monthly Income × 0.36
3. Max Mortgage Payment = min(Max Housing Cost, Max Total Debt - Other Monthly Debts)
The calculator uses the lower of these two results to determine your maximum affordable monthly mortgage payment (PITI). It then works backward to find the total loan amount you could get with that payment, given your specified interest rate and loan term.
Interpreting Your Affordable Price
The primary result is the **Affordable Home Price**. This is the estimated maximum sale price you should consider, calculated by adding your down payment to the maximum loan amount you can afford. The breakdown also shows you the **Estimated Monthly Payment**, giving you a clear idea of your ongoing financial commitment. Remember that this is a guideline; you may want to aim for a lower price to leave more room in your budget for other savings and expenses.
Common Affordability Myths
- Myth 1: The bank's pre-approval amount is what I can afford. A pre-approval letter from a lender shows the maximum they are willing to lend you, not what you can comfortably afford. It doesn't account for your personal savings goals, lifestyle, or other costs of homeownership like maintenance and utilities.
- Myth 2: I only need to save for the down payment. False. You also need to budget for closing costs, which are typically 2-5% of the home's purchase price and cover fees for appraisal, title, origination, and more.
- Myth 3: A 30-year mortgage is always the best choice. While a 30-year term offers the lowest monthly payment, you'll pay significantly more in interest over time. If you can afford the higher payments of a 15-year mortgage, you can save tens of thousands of dollars.
Frequently Asked Questions
How much house can I afford?
A general rule of thumb is the 28/36 rule, which suggests your monthly housing costs (including principal, interest, taxes, and insurance) should not exceed 28% of your gross monthly income, and your total debt payments should not exceed 36%. Our Home Affordability Calculator uses this rule to give you a personalized estimate.
How is home affordability calculated?
Home affordability is calculated by taking your gross annual income and applying debt-to-income (DTI) ratios. Lenders look at your front-end DTI (housing costs) and back-end DTI (all debts). The lower of these two determines the maximum monthly payment you can afford, which is then used to calculate the corresponding loan amount.
Does my down payment affect how much house I can afford?
Yes, a larger down payment directly increases how much house you can afford. Since the affordability calculation determines the maximum loan amount, a larger down payment adds to that loan amount to determine your total affordable purchase price.
What is included in monthly housing costs?
Monthly housing costs, often referred to as PITI, include Principal (the loan amount), Interest (the cost of borrowing), Taxes (local property taxes), and Insurance (homeowner's insurance). It can also include Private Mortgage Insurance (PMI) and HOA fees.
Tips for Improving Affordability
- Improve Your Credit Score: A higher credit score qualifies you for lower interest rates, which significantly increases your purchasing power.
- Pay Down High-Interest Debt: Reducing your monthly debt payments (like credit cards or personal loans) lowers your back-end DTI ratio, allowing you to qualify for a larger mortgage.
- Increase Your Down Payment: Every extra dollar you save for a down payment directly increases your affordable home price.
- Shop for a Lower Interest Rate: Get quotes from multiple lenders to find the best possible interest rate for your situation.
