A purchase price alone does not determine whether a home fits your finances. These four numbers provide a better picture of your overall home-buying position.
Gross Income
Your documented monthly income helps establish the starting point for affordability and qualification estimates.
Monthly Debt
Car loans, credit cards, student loans and other recurring debts can reduce available borrowing capacity.
Cash Available
Your down payment, closing costs and reserves determine how much cash may be required before purchasing.
Total Housing Cost
Principal, interest, property taxes, insurance, PMI and HOA fees can all affect your monthly housing budget.

Affordability and Mortgage Qualification Are Not the Same Thing
Affordability is a personal budgeting decision. It asks what housing payment comfortably fits your income, savings goals, lifestyle and other expenses. Mortgage qualification is a lender underwriting decision.
A lender may approve a mortgage amount that is higher than what you personally feel comfortable paying each month. Using several calculators together can help you evaluate both sides of that decision before shopping for a home.

Frequently Asked Questions
What is a debt-to-income ratio?
Debt-to-income ratio compares recurring monthly debt obligations with gross monthly income. Mortgage lenders commonly review DTI when evaluating a borrower.
Does DTI affect mortgage qualification?
Yes. DTI can be an important underwriting factor, although lenders also evaluate credit, income documentation, assets, down payment, property details and loan program requirements.
Is affordability the same as mortgage qualification?
No. Affordability is about what comfortably fits your personal budget. Qualification is based on lender and loan-program underwriting standards.
How much money should I have before buying a home?
Buyers may need funds for a down payment, closing costs, inspections, prepaid taxes and insurance, moving expenses, repairs and emergency reserves.
Should I calculate my DTI before shopping for a home?
Yes. Calculating DTI early can help show how much income is already committed to recurring debt and whether reducing debt may improve your buying position.
Which home buying calculator should I use first?
The Debt-to-Income Ratio Calculator is a useful starting point. From there, estimate affordability, down payment, closing costs and finally the resulting mortgage payment.
