What Is a Jumbo Loan?

A jumbo loan (also called a non-conforming loan) is any mortgage that exceeds the conforming loan limit set annually by the Federal Housing Finance Agency (FHFA). For 2026, the baseline conforming limit for a single-family home is $832,750, with a high-cost ceiling of $1,249,125 in markets like San Francisco, New York City, Honolulu, and parts of Los Angeles. (Source: FHFA 2026 Conforming Loan Limit Announcement.)

Because Fannie Mae and Freddie Mac will not purchase loans above this limit, jumbo loans are held on lender balance sheets or sold to private investors. This makes them riskier for lenders, so qualification standards are stricter than for conventional conforming loans.

Jumbo Loan Qualification Requirements

• Credit score: Minimum 680 for most lenders; 720-740+ preferred for best rates; 760+ for loans above $2M.
• Down payment: Typically 10-20% for loans up to $1.5M; 20-25%+ for loans above $2M. A 20% down payment on a $1.25M home is $250,000.
• Debt-to-income (DTI): Maximum 43% in most cases; some lenders allow up to 50% with strong reserves.
• Reserves: 6-12 months of PITI in liquid assets after closing. On a $1M loan with $7,000/mo PITI, that is $42,000-$84,000 in reserves.
• Appraisal: Often requires two independent appraisals for loan amounts above $1M.
• Documentation: Full income documentation (2 years of W-2s or tax returns, recent pay stubs, asset statements).

Do Jumbo Loans Have PMI?

Jumbo loans typically do not carry traditional private mortgage insurance (PMI), even when the down payment is less than 20%. Instead, lenders absorb the risk internally and charge a higher interest rate — often 0.125% to 0.50% higher than the conforming rate, known as loan-level price adjustments. Some lenders require 20% down to avoid this pricing hit entirely. the jumbo loan calculator above does not add PMI, since it is uncommon on jumbo loans — but the interest rate you input should reflect the actual quote from your lender, including any LLPAs.

Jumbo Loan Rates vs Conforming Rates

Historically, jumbo rates ran 0.25-0.75% higher than conforming rates because lenders couldn't sell them to Fannie/Freddie. Since 2022, this gap has narrowed or even inverted — many large banks now offer jumbo rates below conforming rates because jumbo borrowers represent very strong credit profiles and the loans are profitable to hold on portfolio. Check current rates on the Freddie Mac PMMS and compare to your lender's jumbo quote.

VA Jumbo Loans for Veterans

Eligible veterans, active-duty service members, and surviving spouses can use a VA loan to finance a home above the conforming limit with no down payment — provided their full VA entitlement covers the loan amount. Above the county conforming limit, the VA requires a 25% down payment on the amount over the conforming limit (the "VA jumbo loan"). The VA loan calculator handles funding fee math; for entitlement-specific calculations, contact a VA-approved lender.

Jumbo Refinance Considerations

Refinancing a jumbo loan follows the same break-even logic as conforming loans, but with two wrinkles: (1) closing costs are typically higher ($5,000-$15,000 vs $3,000-$8,000 for conforming), and (2) some lenders require a new full appraisal even for rate-and-term refinances. Use our refinance calculator with a realistic closing-cost estimate for jumbo-size loans.

2026 Conforming Loan Limits: County-by-County Boundaries

Whether your loan is classified as conforming or jumbo depends on your county's specific conforming loan limit. The FHFA publishes county-level limits annually. Below are the four limit tiers for single-family homes in 6 representative counties and the implications for jumbo qualification:

The FHFA sets the baseline at 115% of the national median home price and caps high-cost limits at 150% of the baseline ($832,750 × 1.50 = $1,249,125). Counties between the baseline and the ceiling have limits proportional to local median prices. Alaska, Hawaii, Guam, and the U.S. Virgin Islands have separate, higher limits for multi-unit properties. (Source: FHFA Conforming Loan Limit Values 2026.) If your loan amount falls within the conforming limit for your county, use the conventional mortgage calculator instead — it includes PMI modeling and LLPA pricing that the jumbo calculator does not need.

Super-Jumbo Loans ($3M+): Portfolio Lending and Private Banking

Loans above $3 million enter super-jumbo territory — a market that operates entirely outside Fannie Mae and Freddie Mac guidelines. These loans are held on the balance sheet of the originating bank (portfolio lending) or through a private banking relationship. Qualification looks very different from standard jumbo:

• Down payment: 25%–35% minimum. On a $4M purchase, expect $1M–$1.4M in cash down.
• Credit score: 720–740 absolute minimum; 760+ expected for best pricing.
• Reserves: Typically 12–24 months of PITI in liquid post-close assets (not retirement). On a $4M loan at $28,000/month PITI, that is $336,000–$672,000 in reserves.
• Asset under management (AUM) relationship: Private banks (J.P. Morgan Private Bank, Goldman Sachs Private Wealth, Citi Private Bank, First Republic) typically require $1M–$5M+ in assets under management at the institution to access their best super-jumbo rates.
• Income documentation: Self-employed borrowers may need 3 years of tax returns plus a CPA letter; W-2 borrowers need 2 years plus current pay stubs.
• Asset depletion loans: Some portfolio lenders qualify super-jumbo borrowers based on liquid asset depletion rather than income — dividing total liquid assets by the loan term (in months) to derive "monthly income."
• Interest-only options: Super-jumbo lenders frequently offer interest-only periods of 5–10 years, which reduce the monthly payment by 20%–30% during the IO period. After the IO period, the loan amortizes over the remaining term, increasing the monthly payment.

the jumbo loan calculator above works for super-jumbo loan amounts — enter the full loan principal — but note that super-jumbo rates are typically 0.25%–1.00% above standard jumbo rates, and the terms are customized per borrower. Use a rate quote from your private banker rather than the published market rate for the most accurate estimate.

Jumbo Loan Reserve Requirements: What Lenders Actually Verify

Reserves are the jumbo lender's #1 non-negotiable — more important than credit score or down payment after a certain point. Reserves must be liquid and verified — checking, savings, money market, and non-retirement brokerage accounts count; 401(k) and IRA accounts count at 60%–70% of their value (to account for taxes and penalties); business assets count if the borrower is the sole proprietor and the business is not negatively affected by the withdrawal. The reserve requirement is calculated as a multiple of the new monthly PITI (principal, interest, taxes, and insurance):

Lenders verify reserves by averaging the last 2–3 months of account statements — a large recent deposit (over 50% of your monthly income) must be "sourced and seasoned" (explain where it came from: a gift, a bonus, a sale of an asset). Gift funds for the down payment are acceptable on jumbo loans, but they cannot count toward reserve requirements. Reserves must remain in your account at closing — they are not a cost, but they tie up liquidity that you cannot spend for other purposes.

Self-Employed Jumbo Borrowers: Bank Statement Loan Qualification

Self-employed borrowers often struggle to qualify for jumbo loans because their tax returns (which maximize deductions) show lower income than their actual cash flow. Bank statement loans solve this problem for jumbo borrowers: instead of tax returns, the lender uses 12–24 months of personal or business bank statements to verify income. The lender calculates average monthly deposits and uses roughly 50%–90% of that figure as qualifying income, depending on the expense ratio of the business. Jumbo bank statement loans typically require: (1) 20%–30% down payment (the lowest down payment reported is 15% but is rare); (2) 680–700+ credit score; (3) 6–12 months reserves; (4) 2 years of bank statements (personal + business if self-employed); (5) a CPA-prepared profit-and-loss statement for the current year. Rates on bank statement jumbo loans run 0.50%–1.50% above full-doc jumbo rates. the jumbo loan calculator above uses the standard amortization formula — enter your loan amount and the quoted rate from your bank statement lender to get an accurate monthly P&I estimate.

How This Calculator Works

Last updated: June 29, 2026

This jumbo loan calculator uses the standard amortization formula. There is no proprietary or hidden math.

Two-step calculation

1. Compute monthly P&I.

   M = P × [ r(1 + r)n ] / [ (1 + r)n − 1 ]

   For $1,000,000 at 6.75% for 360 months: M ≈ $6,486.00.
2. Flag jumbo status. If the loan amount exceeds the local conforming limit ($832,750 baseline / $1,249,125 high-cost), the jumbo loan calculator flags it as jumbo. The conforming limit only affects the loan-status label — it does not change the math.

Verify it in a spreadsheet

=PMT(0.0675/12, 360, -1000000)

Result: $6,486.00 — matches the jumbo loan calculator above. (Source: amortization formula matches the CFPB Loan Estimate tool math.)

Assumptions & limitations

• No PMI is included. Jumbo loans typically don't carry PMI; the lender's interest rate quote should already reflect any LLPAs.
• Property taxes and homeowners insurance are NOT included. On a $1M+ home, these can add $800-$2,500/month depending on jurisdiction.
• Conforming limit defaults to $832,750. In high-cost counties, your actual limit may be up to $1,249,125. The label updates only if the loan exceeds $832,750.
• Rate does not include discount points or origination fees. Use the APR your lender quotes on the Loan Estimate.
