Monthly housing budget
Loan term
This estimate uses gross annual income, existing monthly debt, a maximum debt-to-income ratio, a fixed rate, and the loan term. It is not a lending approval or financial advice; property taxes, insurance, fees, and lender rules are not included. Currency selection only changes formatting.
Useful context
How it works
Use the calculator first, then scan the details below when you want more context about the inputs, result, or assumptions.
How to use it
Enter income, existing monthly debt, deposit, interest rate, term, and a maximum debt-to-income ratio.
Understand the result
Estimated home price is the modeled loan plus the deposit. It is not an approval amount or a recommendation.
Example
With $90,000 gross annual income, $500 in monthly debts, a $60,000 deposit, and a 36% ratio, the result is an estimate to explore—not a lender quote.
Notes
Taxes, insurance, fees, credit rules, property costs, and local lending requirements are not included. This is general information, not financial advice.
