Affordability Calculator – Estimate Your Budget

Field Explanations

Gross Monthly Income ($): Enter your total gross monthly income before taxes and deductions. Include salary, bonuses, overtime, and other regular income sources. This income assessment is the foundation of any sound household budget. (Use our income calculator for detailed calculations)

Monthly Debt Payments ($): Include all minimum monthly debt payments such as credit cards, auto loans, student loans, personal loans, and other recurring debt obligations. Do not include utilities or the proposed mortgage payment. How much are your monthly expenses? Our Debt to income calculator will help with debt management and expense reduction planning.

Credit Score: Select your credit score range. Higher scores qualify for better PMI insurance rates and loan terms, directly lowering your monthly expenses. Most people have three credit scores. But what is the credit score for a husband and wife, or two home buyers? Our credit score analyzer can give you the credit score lenders use. See Credit Score Average Calculator for help understanding credit score impact.

Down Payment: Choose the percentage of the home price you plan to pay upfront. Remember: 20% or more eliminates insurance requirements and reduces your long-term planning risk.

Target DTI Ratio (%): Select your debt-to-income ratio limit based on loan program requirements and your financial profile. This determines how much of your income can go toward all debt payments including the new mortgage.

Loan Term (years): Length of the mortgage loan, typically 15 or 30 years. Shorter terms have higher monthly payments but lower total interest costs—an important factor in long-term planning.

Interest Rate (%): Enter the current mortgage interest rate you expect to receive based on market conditions and your creditworthiness.

Loan Type: Choose between Fixed Rate (interest rate stays the same throughout the loan) or Adjustable Rate (interest rate can change over time). Note: Adjustable rates typically have higher insurance costs.

Private Mortgage Insurance: Automatically calculated when down payment is less than 20%. Insurance rates vary by credit score, down payment amount, and loan type. Insurance protects the lender if you default on the loan. This calculator uses the monthly premium and provides only an estimate - costs vary by lender and property location.

Closing Costs (% of loan amount): Select the percentage for title insurance, transfer taxes, settlement fees, title search, and other closing expenses. Rates vary by location and lender.

Annual Property Taxes (% of home price): Enter your local property tax rate as a percentage of home value. Check with your local tax assessor for accurate rates in your area.

Annual Insurance (% of home price): Enter your homeowner's insurance cost as a percentage of home value. Rates vary by location, home type, and coverage level.

Monthly HOA ($): Enter monthly homeowner's association fees if applicable. Include any special assessments or additional community fees.

Seller Contribution: Amount the seller pays toward buyer's closing costs and prepaid expenses. Maximum contribution limits are based on down payment percentage: 0–9.99% down = max 3%, 10–24.99% down = max 6%, 25%+ down = max 9%.

Frequently Asked Questions
