How Affordability Calculations Work
Understanding how lenders and financial advisors calculate home affordability helps you make informed decisions and avoid costly mistakes. Our calculator uses multiple approaches to determine your maximum house price, ensuring you get a realistic and conservative estimate that protects your financial well-being. The process involves analyzing your debt-to-income ratios, evaluating down payment impact, and factoring in all monthly housing costs.
🔢 Step-by-Step Calculation Process
Step 1: Calculate Maximum Housing Payment
Step 2: Calculate Principal & Interest
Step 3: Add Down Payment
Step 4: Validate Ratios
The 28/36 Rule Explained
The 28/36 rule serves as the foundation for responsible home buying, establishing that your housing costs should not exceed 28% of your gross monthly income while your total debt payments should stay below 36% of your income. These conservative guidelines, developed by lenders and financial experts, help ensure you can comfortably afford your mortgage payments while maintaining financial flexibility for other life goals and unexpected expenses. Understanding these ratios is crucial for loan qualification and long-term financial stability.
⚠️ Important: Why These Limits Exist
The 28/36 rule isn't arbitrary - it's based on decades of lending experience and default data. Borrowers who exceed these ratios are statistically more likely to struggle with payments, especially during economic downturns, job loss, or unexpected expenses. Following these guidelines helps ensure you maintain financial stability and can handle homeownership costs long-term.

Down Payment Impact
Your down payment amount significantly affects not only your monthly mortgage payment but also your loan terms, interest rates, and whether you'll need private mortgage insurance (PMI). Understanding how different down payment percentages impact your total housing costs helps you balance immediate cash outlay with long-term monthly affordability and overall loan economics. Consider available first-time buyer programs and various loan options to optimize your down payment strategy.
💸 5% Down
Higher monthly payments, mortgage insurance required
💰 10% Down
Still requires PMI but lower monthly cost
✅ 20% Down
Avoids mortgage insurance, better rates
🎯 25%+ Down
Lowest rates, reduced loan amount
Monthly Housing Costs (PITI)
True housing affordability extends beyond just the mortgage payment to include the complete PITI package: Principal, Interest, Taxes, and Insurance, which together form your core monthly housing obligation. Understanding these four components and how they interact helps you accurately budget for homeownership and avoid the common mistake of underestimating total monthly costs. Don't forget to factor in additional monthly expenses like PMI, HOA fees, and utilities for a complete picture of your housing costs.
🏠 What's Included in Housing Payment
Principal
Loan amount repayment
Interest
Cost of borrowing money
Taxes
Property tax payments
Insurance
Homeowners insurance
Additional Monthly Costs
Beyond the basic PITI payment, homeownership involves numerous additional monthly expenses that can significantly impact affordability, including PMI, HOA fees, utilities, and ongoing maintenance costs. Factoring these often-overlooked expenses into your affordability calculations prevents budget shock after purchase and ensures you can truly afford the total cost of homeownership. Planning for these costs is essential when considering your overall affordability strategy and hidden homeownership expenses.

Income Verification
Lenders use strict guidelines to verify and calculate qualifying income, with different requirements for W-2 employees, self-employed borrowers, and those with non-traditional income sources like investments or alimony. Understanding how lenders evaluate your income helps you present your financial situation effectively and ensures your affordability calculations align with actual loan approval criteria. This verification process is crucial for successful pre-approval and determines your actual purchasing power based on different loan programs.

Credit Score Impact
Your credit score directly influences both your loan approval chances and the interest rate you'll receive, with higher scores unlocking better terms that can save thousands over the life of your mortgage. Understanding credit score requirements across different loan programs helps you target appropriate financing options and work on credit improvement strategies before applying. Even small improvements in credit score can significantly impact your overall affordability.

Consider first-time buyer programs for additional assistance and explore how different programs affect your down payment strategy.
