Estimate a purchase range

Build a simple planning scenario.

Adjust the assumptions to see how debts, down payment, rate, term, and monthly property costs can affect an estimated purchase range.

Use monthly income before taxes and deductions. This calculator is only a planning snapshot.

Include recurring monthly obligations such as auto loans, student loans, credit cards, personal loans, and minimum required payments.

Cash you plan to put toward the purchase price, not including closing costs or reserves.

Use a planning rate only. Actual rates depend on market conditions, credit, loan program, property, and timing.

The number of years used to calculate principal and interest. Common examples are 30, 20, or 15.

The share of gross monthly income used as a planning limit for housing plus other debts. This is not an approval threshold.

Use a monthly estimate. Actual property taxes depend on location, assessed value, exemptions, and local rules.

Use a monthly estimate. Actual premiums vary by property, coverage, and insurer.

Use monthly association dues if the property has an HOA.

Use a monthly estimate if mortgage insurance may apply. Some loan types use different insurance or funding-fee structures.

How to use this

What the affordability estimate can and cannot show.

The calculator converts a target planning DTI into a housing budget, subtracts monthly taxes, insurance, HOA dues, and mortgage insurance, then estimates the loan amount supported by the remaining principal-and-interest budget.

Property taxes, insurance, mortgage insurance, rates, fees, and program rules can change the final number. Treat the result as a range to discuss, not a final answer.
