Xtreme Mortgage Calculator
A beautiful, fully-featured mortgage calculator for WordPress. Supports Conventional, FHA, VA, USDA, and Jumbo loans with real-time payment breakdowns, PMI estimation, and debt-to-income ratio analysis — all embedded with a single shortcode.
Qualification vs. Affordability
What a lender approves you for and what you can comfortably afford are two different numbers. This calculator helps you find both.
Qualification = Lender Max
The maximum amount a lender will approve based on your DTI ratio, credit score, and debt obligations. This is a ceiling, not a target.
Affordability = Your Comfort
Your comfortable monthly payment after accounting for savings goals, lifestyle expenses, and financial breathing room. Use DTI and budget rules (28/36 or 50/30/20) to avoid payment shock.
Hidden Cost Impact
Taxes, insurance, and HOA fees can shift your total payment more than the interest rate itself. Always calculate the full picture before committing.

Understanding Debt-to-Income Ratios
Lenders use DTI ratios to determine a borrower's ability to manage monthly payments and repay debts. This measurement compares the amount of debt you pay monthly against your gross monthly income.
Front-End DTI
The proportion of your gross monthly income that goes specifically toward housing costs — mortgage principal and interest, property taxes, homeowners insurance, and HOA fees. Lenders use this to ensure housing expenses alone don't overwhelm your budget.
Back-End DTI
The ratio of your gross monthly income that goes toward servicing all of your debt — housing costs plus car payments, student loans, minimum credit card payments, child support, and any other recurring obligations.
Example Scenario
This example uses a 50% back-end DTI. Your actual limit depends on loan type, credit score, and lender overlays.
Supported Loan Types
Each loan type has different DTI limits, down payment requirements, and PMI rules. The calculator adjusts automatically.
Conventional
Standard loans not backed by a government agency. Typically require higher credit scores but offer competitive rates and flexible terms.
FHA
Federal Housing Administration loans designed for first-time buyers and those with lower credit scores. More lenient qualification requirements.
VA
Department of Veterans Affairs loans for eligible service members, veterans, and surviving spouses. No down payment or PMI required.
Jumbo / Non-Conforming
Loans that exceed conforming loan limits set by the FHFA. Used for higher-priced properties with stricter qualification criteria.
USDA
United States Department of Agriculture loans for rural and suburban homebuyers. Zero down payment with income eligibility requirements.
Costs Beyond Principal & Interest
Your mortgage payment is only part of the picture. These additional costs can significantly impact your true monthly housing expense.
Property Taxes
Location dependent — varies widely by county and state. Can add $200–$800+ per month to your payment.
Homeowners Insurance
Estimated $1,000–$3,000 annually ($83–$250/month). Required by all lenders.
Private Mortgage Insurance (PMI)
Generally required when the down payment is less than 20%. Typically 0.5%–1.5% of the loan amount annually.
Home Maintenance & Repairs
Budget 1%–2% of the home value annually. Not included in your mortgage payment but critical for budgeting.
Utilities & HOA Fees
Often exceed projections. HOA fees can range from $100–$700+/month depending on the community.
