How much house can I afford?
A mortgage affordability calculator estimates a sensible home-price range from the money coming into your household, the debts you already pay, the cash available for the purchase and the expected cost of owning the home. It is more useful than looking at the mortgage payment alone because property taxes, homeowners insurance, association fees, closing costs and savings goals can materially change what fits your budget.
Use the maximum property price as a planning boundary, not a spending target. A lender may approve more or less after reviewing verified income, credit history, assets, property details and the selected loan program.
How this mortgage affordability calculator works
The calculator first applies the selected total debt-to-income limit to gross monthly income. Existing car, student-loan, credit-card and other required debt payments reduce the amount available for housing. In U.S. mode, it also applies a separate housing-expense limit and uses the lower result.
Estimated taxes, insurance and fees are deducted before the remaining housing budget is converted into a mortgage amount using the entered interest rate and term. Your usable down payment is then added to estimate a property price. Closing costs and your chosen emergency reserve are kept separate, so the calculator does not assume every dollar of savings can be spent on the down payment.
Income and monthly debts
Enter gross household income before taxes and deductions. Include recurring obligations that a lender may count, such as vehicle payments, student loans and credit-card minimums. Reducing a monthly debt can sometimes improve affordability more than adding the same amount to savings.
Down payment and cash to close
Your down payment reduces the mortgage balance, but it is not the only cash needed. Buyers may also need funds for lender charges, title services, prepaid taxes and insurance, inspections and other settlement expenses. Keep those amounts separate from emergency savings.
Interest rate and mortgage term
A higher rate reduces the loan supported by the same monthly budget. A longer term normally lowers the scheduled payment but can increase total interest. Test several rates and terms instead of relying on one optimistic scenario.
Taxes, insurance and HOA fees
These costs are part of the monthly housing burden even though they do not reduce the loan principal. Estimates can vary substantially by property and location, so replace the defaults with local figures whenever possible.
What is the 28/36 mortgage rule?
The 28/36 rule is a traditional planning guideline, not a universal approval law. It suggests keeping total monthly housing expenses near 28% of gross monthly income and all monthly debts near 36%. Actual underwriting can use different limits depending on the loan program, automated underwriting findings, credit, reserves and other factors. The U.S. scenario controls let you compare conservative and higher-limit assumptions while keeping the ratios visible.
Affordability is different from mortgage qualification
Qualification asks whether a lender may approve the loan. Affordability asks whether the payment leaves enough room for food, utilities, health care, childcare, transportation, maintenance and long-term savings. The emergency-fund guardrail helps preserve part of your cash instead of treating lender approval as proof that the home is comfortable for your budget.
If you already know the home price, use the target-home check to see the required income, resulting DTI and cash shortfall. The “What needs to change?” results then show whether a lower price, larger down payment, reduced debt or additional income would close the gap. For a payment-first estimate, use the mortgage calculator.
Mortgage affordability questions
How accurate is a mortgage affordability calculator?
It is a planning estimate based on the figures and ratios entered. Actual approval depends on verified documentation, credit, loan limits, property eligibility, reserves and lender underwriting. More accurate tax, insurance, debt and closing-cost inputs produce a more useful estimate.
Should I use gross or net income?
Mortgage DTI calculations commonly use qualifying gross income before taxes. Your personal comfort check should also consider take-home pay and real household spending because those determine how much cash remains each month.
Do I need a 20% down payment?
Not always. Some eligible buyers use lower-down-payment conventional or government-backed programs. However, a smaller down payment increases the loan-to-value ratio and may introduce mortgage insurance, funding fees or a higher monthly payment.
Which debts affect how much house I can afford?
Common examples include vehicle loans or leases, student loans, credit-card minimum payments, personal loans, support obligations and other recurring debts. Treatment varies, so confirm uncertain obligations with a lender.
Why keep an emergency fund after buying?
Homeownership can create irregular costs for repairs, insurance deductibles, moving and maintenance. Preserving several months of essential expenses can reduce the risk of relying on new debt immediately after closing.
