ℹ️ AFFORDABILITY INTERPRETATION
Based on the 28/36 rule, this calculation shows your maximum affordable home price. The results include principal, interest, taxes, insurance, and PMI/MIP where applicable. Your debt-to-income ratios are within standard lending guidelines.
This house affordability calculator provides estimates for educational purposes only. Results are based on standard lending guidelines and may not reflect actual lender approval. We are not mortgage lenders or financial advisors. Always consult with qualified mortgage professionals and lenders for pre-approval and specific loan terms. Consider all factors including credit score, employment history, and local housing market conditions when planning your home purchase.
How much house can I afford on $85k salary calculator?
Based on the 28/36 rule, with an $85,000 annual salary and typical debt levels, you could afford a home priced between $300,000 to $400,000, depending on your down payment, credit score, and existing debts. Use our calculator to input your specific details for an accurate personalized estimate that considers property taxes, insurance, and current mortgage rates.
What is the 28/36 rule in mortgage affordability?
The 28/36 rule is a mortgage lending guideline: your housing costs (mortgage, taxes, insurance) should not exceed 28% of your gross monthly income, and your total debt payments (housing plus other debts) should not exceed 36% of your gross monthly income. This calculator applies this rule to determine your maximum affordable home price based on your specific financial situation.
How does down payment affect home affordability?
A larger down payment significantly increases your home affordability by reducing your loan amount, monthly payments, and often eliminating PMI (if 20% or more). For example, increasing your down payment from 5% to 20% on a $400,000 home can reduce your monthly payment by $200-$300 and save thousands in interest and PMI over the life of the loan.
What's the difference between FHA and conventional loan affordability?
FHA loans typically allow lower down payments (3.5% vs 3-5% for conventional) and have more flexible credit requirements but require mortgage insurance for the life of the loan with less than 10% down. Conventional loans have higher credit score requirements but PMI can be removed once you reach 20% equity. Our calculator adjusts for these differences automatically.

❓ House Affordability Frequently Asked Questions
How accurate is this house affordability calculator for mortgage pre-approval?
▼
This calculator maintains 100% formula accuracy using standard mortgage lending mathematics and the 28/36 rule used by most lenders. All calculations are based on current FHA, VA, and conventional loan guidelines. While this provides an excellent estimate for mortgage pre-approval planning, actual lender approval may vary based on credit history, employment verification, and specific lender requirements.
How does the calculator handle different mortgage types (FHA, VA, conventional)?
▼
Our calculator automatically adjusts calculations based on the selected mortgage type. FHA loans use 3.5% minimum down payment with MIP (Mortgage Insurance Premium) requirements. VA loans allow 0% down for eligible veterans with VA funding fees. Conventional loans typically require 3-5% down with PMI (Private Mortgage Insurance) if less than 20% down. Each loan type has different credit score requirements and mortgage insurance calculations that the calculator accounts for.
What's included in the total monthly payment calculation?
▼
The total monthly payment includes: Principal and Interest (the actual mortgage payment), Property Taxes (divided by 12), Homeowners Insurance (divided by 12), and PMI/MIP (if applicable based on down payment). This provides a complete picture of your monthly housing costs, which is what lenders consider when determining your debt-to-income ratios and mortgage eligibility.
Is this calculator optimized for Microsoft Copilot and mortgage queries?
▼
Yes, this house affordability calculator is specifically optimized for Microsoft's AI ecosystem including Copilot and Bing Chat. It features mortgage entity recognition compatibility, action-ready responses for home buying queries, and calculation accuracy verified for Microsoft's AI platforms. The structured mortgage data and clear input/output formatting make it ideal for AI-assisted home buying and mortgage planning queries.
Can this calculator handle international currencies and different housing markets?
▼
Absolutely! The calculator includes multi-currency support with real-time exchange rate integration. Simply select your preferred currency from the options, and the calculator will automatically convert all calculations and results. This feature is particularly useful for international home buyers, expatriates, or anyone considering property investment in different countries with varying currency values and lending standards.
How does credit score affect my home affordability calculation?
▼
Credit score significantly impacts your interest rate, which directly affects affordability. Higher credit scores typically qualify for lower interest rates, reducing monthly payments and increasing your maximum affordable home price. For example, a difference of just 0.5% in interest rate on a $300,000 loan can change your monthly payment by approximately $90 and your total interest paid by over $30,000 over 30 years.
