Jumbo Loan Mortgage Calculator

A jumbo loan is any mortgage that exceeds the conforming loan limit set by the Federal Housing Finance Agency (FHFA). In 2026, the baseline conforming limit for a single-family home is $806,500 in most of the country, with higher limits (up to roughly $1.2 million) in designated high-cost areas. Any loan amount above your local limit requires jumbo financing, which is not eligible for purchase by Fannie Mae or Freddie Mac.

Because jumbo loans carry more risk for lenders, qualification is stricter. Most jumbo lenders require a credit score of 700 or higher, a down payment of at least 10–20%, a debt-to-income ratio typically below 43%, and significant cash reserves (often 6–12 months of payments). Documentation of income and assets is more extensive than with a conforming loan.

Jumbo loan rates can differ from conventional rates because lenders hold these loans on their own books rather than selling them to government-backed investors. That means pricing is set by each lender's appetite for risk and portfolio strategy rather than the broader conforming market. As a result, jumbo rates can sometimes be lower than conforming rates for well-qualified borrowers, but they also tend to be more variable between lenders — which is why comparing offers from multiple jumbo specialists matters more here than with a standard mortgage.
