It estimates the home price you can realistically afford based on your income, monthly debts, down payment, and a target debt-to-income ratio.
The Complete Guide
Affordability is not the same as approval. A lender may approve you for a payment that leaves no breathing room, so the calculator is best used to find a comfortable number rather than a maximum one. Start with a conservative debt-to-income ratio and see what price it supports.
Your existing debts matter as much as your income. Car loans, student loans, and minimum credit-card payments all reduce the housing budget the calculator returns. Paying down a card or two before you apply can meaningfully raise the price you qualify for.
In Florida, factor in the cost of homeowners insurance and any community fees early. A home that looks affordable on the loan payment alone can stretch your budget once a coastal insurance premium and CDD assessment are added on top.
How the Calculator Works
The tool works backward from your income. It applies a target debt-to-income ratio to find the maximum monthly payment lenders will allow, subtracts estimated taxes and insurance, and converts the remaining principal-and-interest budget into a loan amount and supported home price.
Frequently Asked Questions
What debt-to-income ratio should I use?
A conservative target is around 36% of gross income for total debt, though many programs allow up to 43% to 50%. Lower ratios leave more room for savings and unexpected costs.
Does a bigger down payment let me afford more?
Yes. A larger down payment lowers the loan amount for a given price and can remove mortgage insurance, both of which reduce the monthly payment and raise the price your income supports.
