The jumbo mortgage calculator estimates your monthly payment for loans exceeding conforming limits, including principal, interest, property taxes, and homeowners insurance. Unlike conforming loans, jumbo loans may not require PMI even with less than 20% down, as this varies by lender. The calculator helps you model payments for high-value properties accurately.

Jumbo lenders require 6-12 months of reserves because larger loans carry more risk and the payments are substantial. The calculator can help you determine your reserve requirements by showing your total monthly payment. For example, if your jumbo payment is $5,000 per month, you may need $30,000-$60,000 in verified liquid assets after closing.

Jumbo rates in the calculator may be slightly higher than conforming rates, though the gap has narrowed significantly in recent years. For well-qualified borrowers with 20% down and 740+ credit scores, jumbo rates are often within 0.25% of conforming rates. The calculator lets you adjust the rate to compare different scenarios and lender offers.

Some borrowers use a piggyback structure with a conforming first mortgage and a second loan to avoid jumbo pricing. The calculator can help you compare a single jumbo loan versus a first and second combination. In some cases, the piggyback structure results in lower total payments, especially if you want to avoid the jumbo down payment requirement.

Jumbo adjustable-rate mortgages often start 0.5-1.0% lower than fixed rates, which can mean significant monthly savings on large loan amounts. A 7/1 ARM on a $1 million loan could save $400-$800 per month during the initial fixed period. The calculator can model both options so you can weigh the initial savings against the risk of rate adjustments.
