How the math works
The calculator first turns your income and target debt-to-income ratio into a maximum monthly debt budget, then subtracts existing monthly debts to find room for housing.
The affordable price is solved by testing home prices until the estimated principal, interest, property tax, insurance, and HOA payment fits the monthly housing limit.
EveryCalc calculators are designed for fast, practical estimates with transparent inputs and no required account. We use plain formulas, visible assumptions, and related tools so visitors can check the result from more than one angle.
Results are informational only. For financial, tax, legal, medical, construction, or other high-impact decisions, verify the output against primary sources or a qualified professional.

Calculation notes and example
Income, DTI, and home-price solving method
Gross annual income is divided by 12 and multiplied by the entered back-end debt-to-income ratio to set a maximum total monthly debt budget. Other monthly debts are subtracted to leave the housing limit. The calculator searches for the home price whose principal and interest, annual property-tax percentage divided by 12, monthly insurance, and HOA dues fit that limit after fixed down-payment dollars are applied. It does not add mortgage insurance or special assessments.
Income and debt-budget example
At $110,000 of gross annual income and a 43% target back-end DTI, the modeled total debt budget is about $3,942 per month. Subtracting $650 of auto, student-loan, and card obligations leaves about $3,292 for principal, interest, property tax, insurance, and HOA. The price solution then changes with rate, term, down payment, and local housing costs.
Approval is not the same as comfort
- Enter recurring debts using lender treatment and include applicable obligations that may not appear on a credit report.
- Use property-specific tax, insurance, HOA, and PMI estimates; a broad percentage can materially overstate affordability.
- Test a lower DTI and higher rate. The result does not reserve cash for maintenance, utilities, childcare, income taxes, retirement, or emergencies.

How to interpret the mortgage affordability result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this mortgage affordability estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

How to Use
- Enter gross annual income before taxes and deductions.
- Add recurring monthly debts such as auto loans, student loans, personal loans, and credit card minimums.
- Enter down payment, mortgage rate, term, property tax, insurance, HOA dues, and target back-end DTI.
- Review the estimated affordable home price and modeled PITI plus HOA payment.
- Run a lower price or higher rate scenario before shopping so the approval target is not too tight.
Frequently Asked Questions
What does this mortgage affordability calculator estimate?
It estimates the home price that fits a target back-end debt-to-income ratio after existing debts and modeled housing costs are included.
Does this replace lender preapproval?
No. Lenders also evaluate credit, reserves, assets, loan program rules, property type, mortgage insurance, and documentation. Use this as a planning estimate before preapproval.
Why include taxes, insurance, and HOA dues?
A home can look affordable on principal and interest alone but become stretched once property tax, homeowners insurance, HOA dues, and other required housing costs are included.
What DTI should I use?
A 43 percent back-end DTI is a common reference point, but acceptable ratios vary by lender and loan program. Use a lower ratio if you want more monthly breathing room.
