How to Use This Calculator
Jumbo Payment tab
The default tab. Enter your home price, down payment percentage, and interest rate. The calculator shows your full monthly PITI payment: principal and interest, plus estimated property tax and homeowner's insurance. It also tells you whether your loan is jumbo (exceeds $832,750) or conforming. Expand "More options" to adjust loan term, property tax rate, and insurance rate.
Jumbo vs Conforming tab
Use this to see if putting more money down to stay under the conforming limit saves you money. The calculator compares two options: your planned jumbo loan vs. a conforming loan at $832,750. You'll see exactly how much extra down payment you'd need and how much you'd save per month and over the life of the loan.
Qualification Check tab
Enter your credit score, monthly income, monthly debts, and liquid reserves. The calculator checks each against typical jumbo lender requirements (700+ credit, 43% max DTI, 6-12 months reserves) and tells you which requirements you meet and which need work.

The Formula
Monthly mortgage payment uses the standard amortization formula:
Where:
r = annual rate / 12 (monthly interest rate)
n = term in years × 12 (total payments)
Monthly PITI = P&I + Property Tax/12 + Insurance/12
Total Interest = (Monthly P&I × n) - Loan Amount
Jumbo loans use the same amortization math as conforming loans. The difference is the rate: jumbo rates are typically 0.25% to 0.50% higher because the loan can't be sold to Fannie Mae or Freddie Mac, so the lender holds more risk.
For the qualification check, DTI is calculated as: (all monthly debts + new PITI) / gross monthly income × 100.
Example
The Patel family — buying a home in San Mateo, CA
Raj and Priya Patel earn $22,000/mo gross combined, have $2,800/mo in existing debts (car payment + student loans), and saved $400,000 for down payment and reserves. They're looking at a $1,500,000 home. Credit scores: 760 and 745. Property tax rate in San Mateo: 1.15%.
Jumbo Payment tab
The Patels' loan of $1.2M is well above the $832,750 conforming limit — this is a jumbo loan.
Jumbo vs Conforming tab
Staying under the conforming limit would require 44% down ($667K). That's likely too much cash to tie up. The Patels should take the jumbo loan and keep reserves liquid.
Qualification Check tab
The Patels' DTI is above 43%. They could pay off the car loan ($600/mo) to bring DTI to 44.8% — still tight. A larger down payment (25%) would lower the mortgage payment and help DTI.
