This is a budgeting scenario, not a preapproval or underwriting decision. It excludes closing costs, maintenance, utilities, cash-reserve requirements and household goals.
This calculator turns a monthly housing budget into an estimated home price. It uses a 28% front-end ratio for housing and a 36% back-end ratio for housing plus recurring monthly debt, then applies the down payment and the full estimated monthly cost: principal, interest, property tax, homeowners insurance, PMI and HOA dues.
How to interpret the result
The estimate is a planning ceiling under the assumptions you entered—not a target price and not a lender decision. Underwriting also considers credit history, income stability, assets, loan program, cash reserves, property eligibility and other obligations. A comfortable budget should also leave room for closing costs, repairs, maintenance, utilities, savings and changes in taxes or insurance.
Make the inputs specific
- Include required payments for auto, student, personal and credit-card debt.
- Use a realistic down-payment percentage while keeping closing costs and reserves separate.
- Replace the national rate assumption with a lender quote when available.
- Use a property-specific tax rate and an insurance quote; statewide averages are only a starting point.
- Add PMI when the down payment is below 20% and enter any recurring HOA dues.

Frequently asked questions
How does this calculator decide what I can afford?
It looks at your income, monthly debts, down payment, and estimated rate, then applies standard lending guidelines like the 28/36 rule to estimate the maximum loan and home price you can reasonably support.
What is the 28/36 rule?
It is a common benchmark: aim to keep housing costs near 28% of gross monthly income and total debt payments near 36%. Staying within these ranges helps you qualify and keeps payments manageable.
How does my existing debt affect the result?
Monthly debts raise your debt-to-income ratio, leaving less room for a mortgage payment. Paying down loans or cards before applying can increase how much house you can afford.
How much should I put down?
A larger down payment lowers your loan amount and monthly payment, and putting down 20% typically avoids PMI. Even a smaller down payment can work, but it usually means a higher payment.
Is the maximum amount the amount I should borrow?
Not necessarily. The result is a ceiling based on guidelines, not a budget. Many buyers choose a payment below the max to leave room for savings, repairs, and other goals. See the full payment with our main calculator.
