Jumbo Loan Calculator

Jumbo loan is a US mortgage whose amount exceeds the conforming loan limit set by the Federal Housing Finance Agency (FHFA) for the borrower’s area. Because it exceeds that limit, a jumbo loan generally cannot be purchased by Fannie Mae or Freddie Mac.

Classification is purely about numbers: a $1,200,000 loan in a baseline area (limit $832,750) is jumbo, while the same loan in a high-cost area (limit up to $1,249,125) is still conforming.

Per the FHFA announcement on November 25, 2025, for 2026: the baseline limit for one-unit properties in most of the US is $832,750 (up $26,250 from 2025); the maximum high-cost area limit is $1,249,125 (150% of baseline); for Alaska, Hawaii, Guam, and the US Virgin Islands, the baseline is $1,249,125 and the maximum is $1,873,675.

These figures were last verified against the primary fhfa.gov documents on October 9, 2026. Each county’s limit can differ between the baseline and the maximum, so always check the official FHFA list for your specific county.

Baseline areas use the national $832,750 limit for one-unit properties (2026). A high-cost area is an area whose median home price is far above the national average; there the limit is higher, up to a maximum of $1,249,125 for one-unit properties (2026).

The impact is real: a $1,200,000 loan is jumbo in a baseline area (exceeding $832,750 by $367,250), but conforming in a high-cost area with a $1,249,125 limit (still $49,125 under the limit). The same amount can have a different status in different areas.

In general, jumbo loans and conforming loans differ by who can buy the loan on the secondary market: conforming loans are eligible for purchase by Fannie Mae/Freddie Mac, while jumbo loans are not.

In practice, jumbo loans are often associated with stricter documentation, down-payment, and reserve requirements, and rates that may differ from conforming loans. This is a general descriptive statement — actual terms are always set by each lender and can change.

The rule is simple: compare the loan amount with the conforming loan limit in effect for the property’s area in the current year. If the loan amount exceeds the limit → jumbo; if it is equal to or below the limit → conforming.

Boundary example (2026, baseline area): a loan of exactly $832,750 is still conforming, while $832,751 is already jumbo. The classification mode in this calculator applies the same “≤ limit” rule.

The payment calculation uses the standard amortization formula and has been tested against independent reference vectors. Example: a $1,200,000 loan at 7% over 30 years produces a payment of $7,983.63/month and total interest of $1,674,106.78.

But the result remains an estimate: it excludes property taxes, insurance, closing costs, points, and the lender’s actual rate adjustments. Limit figures follow FHFA data as of October 9, 2026 and may change with the next annual announcement.

No. This calculator is an educational tool: it computes numbers from your inputs and classifies the loan against FHFA limits, without assessing creditworthiness, recommending products, or predicting loan approval.
