Overview

The Jumbo Loan Calculator models a mortgage above the conforming loan limit -- the threshold above which Fannie Mae and Freddie Mac won't purchase or guarantee a loan. Jumbo loans carry their own dynamics: typically higher down payment requirements, a rate premium over conforming loans, and stricter underwriting.

Enter your home price, down payment, and the jumbo rate you've been quoted, alongside a comparable conforming rate for reference. The calculator shows your payment, confirms whether the loan actually exceeds the conforming limit, and quantifies the extra cost of the jumbo rate premium over the life of the loan.

For a standard conventional mortgage, use the Advanced Mortgage Calculator instead.

How This Differs From a Standard Mortgage

Loan Amount = Home Price × (1 − Down Payment %)
Is Jumbo = Loan Amount > Conforming Loan Limit
Rate Premium Cost = (Jumbo Payment − Conforming-Rate Payment) × Total Months

The calculator uses the same amortized-payment formula as the site's other mortgage tools, but explicitly checks your loan amount against the conforming limit you enter and quantifies what the jumbo rate premium costs over the full loan term -- money a standard mortgage calculator won't surface because it doesn't know to look for it.

Frequently Asked Questions

What is the conforming loan limit for 2026?

The baseline 2026 conforming loan limit set by the FHFA is $832,750 for most US counties, up $26,250 from 2025's $806,500. High-cost areas have a ceiling of $1,249,125 (150% of baseline), and Alaska, Hawaii, Guam, and the U.S. Virgin Islands use that higher figure as their own baseline. See the full 2026 conforming loan limits breakdown for the multi-unit table and how high-cost county status is determined, or check your specific county before assuming the standard baseline applies.

Why do jumbo loans need a bigger down payment?

Because Fannie Mae and Freddie Mac won't purchase or guarantee jumbo loans, lenders keep more of the risk on their own books and typically require more equity upfront to offset it.

Do jumbo loans always cost more than conforming loans?

Not always -- rate spreads between jumbo and conforming loans fluctuate with market conditions and sometimes narrow or even invert. This calculator lets you compare your actual quoted rates rather than assuming a fixed premium.

What credit score and down payment do I need for a jumbo loan?

Requirements vary by lender since jumbo loans aren't standardized by Fannie Mae or Freddie Mac -- but most lenders look for a credit score of 700+, a 10-20% down payment, and 6-12 months of cash reserves.
