Maximum Loan Amount Calculator
Two separate ceilings decide how much you can borrow — this shows both.
What This Calculator Does
Works backward from an affordable monthly payment to the loan principal it supports at your rate and term, then compares that figure against the ceiling your lender's maximum loan-to-value places on the loan for a property of that value, with the lower of the two as your effective maximum.
Who Is This For
Buyers who know their comfortable monthly payment, borrowers testing how far a fixed down payment amount reaches, and anyone who wants to understand the basis for a pre-approval figure.
How It Works
Enter the monthly payment you can support, expected rate and term, and, optionally, a property value with your lender's maximum loan-to-value percentage to see the payment-driven loan amount, the loan-to-value ceiling, and which one binds.
Frequently Asked Questions
Why are there two separate ceilings?
A lender evaluates both whether you can make the payment and how much of the property's value it is willing to lend against; both tests must be satisfied, so the lower result becomes your effective maximum.
What is loan-to-value?
Loan-to-value is the loan amount divided by the property's value or purchase price, whichever is lower; a larger down payment lowers this ratio and can improve pricing or remove mortgage insurance.
How does the appraisal affect this calculation?
If an appraisal comes in below the contract price, the loan-to-value ceiling is calculated on the appraised value rather than the agreed price, which can require additional cash or a renegotiated price.
Should I borrow up to my calculated maximum?
The maximum is a boundary rather than a target; borrowing at the very top leaves less room for insurance changes, assessments, or maintenance, so many buyers choose a figure below their calculated ceiling.
