Jumbo Loan Calculator

A jumbo loan finances an amount above the conforming limit. Estimate your payment and see the credit and down-payment expectations lenders look for.

How jumbo loans work

• Loan size: above the conforming limit of about $832,750 for one unit in 2026.
• Mortgage insurance: none monthly, but lenders offset the risk other ways.
• Down payment: commonly 10% to 20%.
• Credit and reserves: stronger requirements than conforming loans.

When you need a jumbo loan

If the price minus your down payment lands above the conforming limit, the loan is jumbo. In higher-cost areas the limit is higher, so the same price may still be conforming. The calculator flags jumbo automatically from your numbers.

Where the jumbo threshold sits and why it moves

A loan is jumbo when it exceeds the conforming limit for the county where the property sits. That limit is reset annually and is higher in designated high-cost counties, so the same loan amount can be conforming in one county and jumbo in the next one over. The comparison that matters is loan amount against the current limit for that specific county, not the purchase price.

This creates a decision point right at the boundary. Increasing the down payment enough to land just under the limit can move the file into conforming pricing and conforming guidelines, which is frequently the cheaper path even though it requires more cash at closing.

How jumbo underwriting differs

Jumbo loans are held by the lender or sold to private investors rather than backed by the agencies, so guidelines are set by whoever carries the risk. Standards tend to be tighter and vary more between lenders than conforming loans do.

Reserves and documentation

Reserves are the requirement borrowers most often overlook. They are months of full housing payment that must remain documented and available after closing, and they are separate from the down payment and closing costs. On a $6,000 monthly payment, a 9-month reserve requirement means $54,000 still sitting in verified accounts after the file funds.

Documentation also runs deeper. Expect full tax returns rather than a transcript summary, verified liquidity for reserves, and more scrutiny of bonus, commission, self-employment, and investment income — which is often the income that pushes a borrower into jumbo territory to begin with.

A loan amount above the conforming limit, about $832,750 for one unit in 2026, though higher-cost counties allow more.

What makes a loan jumbo?

The loan amount exceeds the conforming limit for the county where the property is located. Limits reset annually and run higher in designated high-cost counties, so the same amount can be conforming in one county and jumbo in another.

Should I put more down to stay under the jumbo limit?

Landing just under the limit moves the file into conforming pricing and guidelines, which is often cheaper overall. It requires more cash at closing, so it is a trade worth running both ways.

What are reserves on a jumbo loan?

Months of full housing payment that must remain documented and available after closing, separate from your down payment and closing costs. Six to twelve months is common on jumbo files.
