How to Use the Jumbo Loan Calculator
- 1
Enter the home price and your down payment amount. Jumbo loans typically require a minimum 10% to 20% down payment. A larger down payment lowers your loan amount and monthly payment.
- 2
Enter the annual interest rate for your jumbo loan. Jumbo rates are typically 0.25% to 0.5% higher than conforming loan rates. The US average 30-year jumbo rate in 2026 is approximately 7.0% to 7.5%.
- 3
Enter your discount points if any. Each point costs 1% of the loan amount upfront and typically reduces your rate by 0.25%. Enter your annual property tax, home insurance, and HOA fees to see your complete true monthly cost.

Example Jumbo Loan Calculation
Scenario: Home Price $1,800,000 | Down Payment $300,000 | Rate 7.25% | 30 years | Points 1% | Tax $18,000/yr | Insurance $5,000/yr | HOA $500/mo
- Loan Amount: $1,500,000.00 (JUMBO)
- Down Payment: 16.67%
- Monthly P&I: $10,232.64
- Total Monthly: $12,649.31
- Points Cost (1%): $15,000.00
- Total Interest Paid: $2,183,751.91
- True All-In Cost: $3,998,751.91
- Payoff Date: March 2056
"In this high-value example, interest accounts for over 50% of the total loan cost. Paying 1 point ($15,000) upfront to lower the rate by 0.25% would save approximately $90,000 in interest over 30 years."
Frequently Asked Questions
What is a jumbo loan?
A jumbo loan is a mortgage that exceeds the conforming loan limit set annually by the Federal Housing Finance Agency (FHFA). For 2026, the limit is $806,500 for most US counties. Any loan above this threshold is considered a jumbo loan and cannot be sold to Fannie Mae or Freddie Mac.
Are jumbo loan rates higher?
Typically, yes. Jumbo loan rates are often 0.25% to 0.5% higher than conforming rates because they carry more risk for lenders. However, borrowers with excellent credit and large down payments (20%+) can sometimes secure rates comparable to conforming loans.
What are the requirements?
Most lenders require a credit score of at least 700 to 720, a debt-to-income (DTI) ratio below 43%, and a down payment of at least 10% to 20%. You will also likely need to show 12 months of mortgage payments in cash reserves.
What is the 2026 threshold?
The 2026 conforming loan limit is $806,500 for most of the US. In designated high-cost areas like San Francisco or NYC, the limit can be as high as $1,209,750. Any mortgage loan amount above these specific local limits is a jumbo loan.
