The difference between a conforming and a jumbo mortgage is one number: the conforming loan limit set each year by the Federal Housing Finance Agency (FHFA). A loan at or below that limit is conforming; a loan above it is a jumbo loan, which usually comes with stricter qualifying rules and a larger required down payment.
What the conforming loan limit is
The conforming loan limit is the maximum loan amount that Fannie Mae and Freddie Mac will buy. Lenders prefer conforming loans because they can sell them to those agencies, which is why those loans are easier to qualify for and often priced competitively. For 2025, the FHFA set the baseline one-unit limit at $806,500, with a higher ceiling of $1,209,750 in designated high-cost areas like parts of California, New York, and Hawaii. These limits change every year, so always confirm the current figure for your county before assuming where your loan falls.
The key point for borrowers: it is the loan amount that matters, not the home price. A $1,000,000 home with 25% down means an $800,000 loan - which can stay conforming in many areas. The same home with 10% down means a $900,000 loan, which is a jumbo in most of the country.
How they compare
| Feature | Conforming loan | Jumbo loan |
|---|---|---|
| Loan amount | At or below the FHFA limit | Above the FHFA limit |
| Backed by Fannie/Freddie | Yes | No |
| Typical down payment | As low as 3-5% | Often 10-20%+ |
| Credit score bar | Standard | Higher, often 700+ |
| Cash reserves | Modest | Several months of payments common |
| Documentation | Standard | More thorough |
None of these are universal rules - jumbo guidelines vary widely from lender to lender because each one keeps the loan or sells it privately. But the pattern holds: jumbo loans ask more of you because there is no government agency standing behind them.
The down payment is the biggest practical gap
Because a jumbo lender takes on more risk, it usually wants more skin in the game. On a $1,000,000 home, the difference between a conforming-friendly and a jumbo structure can look like this at a 7% rate over 30 years (principal and interest only):
| Down payment | Loan amount | Loan type (most areas) | Monthly P&I |
|---|---|---|---|
| 10% ($100,000) | $900,000 | Jumbo | $5,987.72 |
| 20% ($200,000) | $800,000 | Conforming (in many counties) | $5,322.42 |
The bigger down payment does two things at once: it can drop you below the conforming limit and it shrinks the loan, lowering the payment by about $665 a month here. If your loan is just over the line, paying down a relatively small amount of extra principal at closing can move you from jumbo to conforming - in this example, $93,500 separates a $900,000 jumbo from the $806,500 baseline limit.

Are jumbo rates higher?
Jumbo rates are sometimes slightly higher than conforming rates and sometimes lower or about the same - it depends on the lender and market conditions, so there is no fixed gap to assume. What matters is that even a small rate difference is large in dollars on a big balance. On an $850,000 loan over 30 years, a quarter-point swing from 7.00% to 6.75% changes the monthly principal and interest from $5,655.07 to $5,513.08 - about $142 a month, or roughly $51,115 in total interest over the full term. Always compare quotes by the actual payment and total interest, not by the headline rate alone, which you can do quickly in the Mortgage Calculator.
Which one will you have?
You do not choose between conforming and jumbo the way you choose a 15- or 30-year term - your loan type is decided by your loan amount versus this year's county limit. What you can control is which side of the line you land on:
- Increase your down payment to bring the loan amount under the limit and avoid jumbo underwriting entirely.
- Buy in a different price range if conforming terms matter to you and your area's limit is tight.
- Strengthen your file - a higher credit score and more cash reserves help most with jumbo approval, where the bar is higher.
Remember that the conforming-versus-jumbo question only affects principal and interest. Your real monthly bill is PITI - it also includes property taxes, homeowners insurance, PMI if your down payment is under 20%, and any HOA dues - so budget for the full picture, not just the payment the calculator shows. Before you shop at all, it helps to know how big a loan your income supports using the Loan Affordability Calculator and to sanity-check the monthly burden against your other debts with the Debt-to-Income Ratio Calculator.
The bottom line
Conforming and jumbo are not two products you pick between - they are two sides of a single line drawn each year by the FHFA. Stay at or below the limit and you get more lenient terms and lower down payments; cross it and you face stricter rules and usually a bigger cash requirement. The current limit changes annually, so confirm your county's figure, then model the loan you would actually take in the Mortgage Calculator to see the payment and total interest before you commit.

- What is the difference between a conforming and a jumbo loan?
- A conforming loan is at or below the annual conforming loan limit set by the FHFA, so it can be bought by Fannie Mae and Freddie Mac. A jumbo loan exceeds that limit, is not backed by those agencies, and usually requires a larger down payment, a higher credit score, and more cash reserves.
- What is the conforming loan limit?
- The conforming loan limit is the maximum loan amount Fannie Mae and Freddie Mac will purchase. For 2025 the FHFA baseline one-unit limit was $806,500, rising to $1,209,750 in high-cost areas. The limits change every year, so confirm the current figure for your county.
- Is it the home price or the loan amount that determines a jumbo loan?
- It is the loan amount, not the home price. A $1,000,000 home with 20% down is an $800,000 loan that can be conforming in many areas, while the same home with 10% down is a $900,000 loan that is usually a jumbo. A bigger down payment can move you from jumbo to conforming.
- Are jumbo mortgage rates higher than conforming rates?
- Not always. Jumbo rates are sometimes slightly higher and sometimes about the same or lower than conforming rates, depending on the lender and market. Because the balance is large, even a 0.25% difference matters - on an $850,000 loan it is about $142 a month and roughly $51,115 over 30 years.
- Do I need 20% down for a jumbo loan?
- Not necessarily, but jumbo lenders commonly want 10-20% or more because there is no government agency backing the loan. Conforming loans can allow as little as 3-5% down. Requirements vary by lender, so compare offers, and remember that under 20% down typically adds PMI to your payment.
- Can I avoid a jumbo loan?
- Yes, often by increasing your down payment enough to bring the loan amount at or below your county's conforming limit. Even a relatively small amount of extra principal at closing can move a loan from jumbo to conforming, which usually means easier qualifying and a smaller cash requirement.
