You found the perfect house at $850,000. Your agent mentions "jumbo loan territory" and suddenly the conversation shifts. Higher rates, bigger down payment, stricter credit requirements. But is it actually a jumbo loan? The 2026 FHFA conforming loan limit is $766,550 for most US counties — up from $726,200 in 2023 — and $1,149,825 in high-cost areas like San Francisco, New York City, and parts of Hawaii.
What the Tool Does
Enter your purchase price, down payment percentage, and county type. The calculator instantly tells you whether your loan falls under conforming or jumbo limits, estimates the rate premium (jumbo loans typically carry 0.25–0.50% higher interest based on credit score tier), calculates your DTI ratio, and shows whether you'd qualify under standard jumbo underwriting guidelines.
Why This Matters in 2026
Mortgage refinance calculators get 74,000 monthly searches in the US at $4.76 average CPC (Google Ads data, April 2026), reflecting intense advertiser demand in the mortgage space. Jumbo loans sit at the premium end of this market — borrowers in the $766,550–$2M range represent the highest-value mortgage segment.
The rate spread between conforming and jumbo has narrowed in 2026. With the Federal Reserve holding rates at 4.25–4.50% after the March 2026 FOMC, 30-year jumbo rates hover around 6.50–7.00% versus 6.25–6.75% for conforming — a smaller gap than the 0.75%+ spread seen in 2023. This makes jumbo loans more competitive than many borrowers expect.

- The estimated rate premium based on your credit score (740+ gets the smallest spread)
- Your DTI ratio and whether it meets the typical 43% jumbo threshold
