The Pre-Approval Calculator estimates how much a lender will likely pre-approve based on your gross income, existing monthly debt obligations, and targeted down payment. Input these factors to see the maximum mortgage amount you'll probably qualify for before formal application.

Who it's for
- Prospective homebuyers gauging likely pre-approval amounts before property search
- Real estate agents qualifying buyers and discussing realistic purchase budgets
- Mortgage brokers pre-screening applicants and explaining qualification likelihood

Frequently asked questions
How accurate is a pre-approval estimate?
Within 10–20% if assumptions are realistic. Actual appraisal and updated income verification may move it.
Does this replace a formal pre-approval?
No — formal pre-approval requires credit pull, application, income verification. Use this for planning before formal application.
What credit score do I need?
FHA: 500+; conventional: 620–640 min; best rates: 740+. Credit quality significantly affects rate and approval.
Can I get pre-approved for more than this estimate?
Possibly — if compensation is higher or debts are lower. Manual underwriting can override automated guidelines.
