Jumbo loans can’t be bought by Fannie Mae or Freddie Mac, so lenders often require larger down payments (10–20%), higher credit scores (700+) and more cash reserves. Rates are sometimes close to conforming rates.

How to use the Jumbo Loan Calculator

  1. Property price
  2. Down payment
  3. Loan term
  4. Interest rate
  5. First payment date
  6. Conforming loan limit in your county

Results update as you type, and every field accepts the units shown in its menu.

How it works

Enter the property price, down payment, term, interest rate and first payment date.

Tips

  • Get a written loan estimate and compare the APR, not just the interest rate.
  • Include property tax, insurance, HOA fees and maintenance in your monthly budget.
  • A larger down payment lowers the payment and can remove mortgage insurance.
  • Rates change daily – use a current quote for the most accurate result.

Common mistakes to avoid

  • Looking only at the monthly payment instead of the total cost of the loan.
  • Forgetting closing costs and fees.
  • Assuming home prices always rise.

What each result means

  • Jumbo loan amount = [Property price]×(1 – [Down payment]÷100)
  • Monthly payment = pmt([Interest rate]÷1200, [Loan term], [Jumbo loan amount])
  • Total interest paid = [Monthly payment]×[Loan term] – [Jumbo loan amount]
  • Total interest as a share of the loan = [Total interest paid]÷[Jumbo loan amount]×100
  • Date of last payment = addmonths([First payment date], [Loan term] – 1)
  • Total debt to repay = [Monthly payment]×[Loan term]
