One loan vs three pieces: how each program is built
A 7(a) loan also covers buying a business and refinancing. A 7(a) loan is one loan from one lender, with the SBA backing up to 85% of loans of $150,000 or less and up to 75% of larger ones [3]. You deal with that lender from application to final payment.
A 504 project has three parts. A bank or other lender provides 50% or more of the financing, a Certified Development Company (CDC) provides up to 40% through a debenture the SBA backs in full, and you put in at least 10% [6]. CDCs are nonprofits certified and regulated by the SBA to promote economic development in their communities [1].
| Piece | Share | Amount |
|---|---|---|
| Bank or other lender, first lien | 50% | $1,000,000 |
| CDC debenture, SBA backed | 40% | $800,000 |
| Your down payment | 10% | $200,000 |
If the business is new, or the building is a special purpose property, your share rises to 15%, and to 20% if both are true, with the CDC piece shrinking to make room [6].
Rates and cost: a capped rate vs a Treasury-linked fixed rate
7(a) rates are negotiated with the lender up to an SBA ceiling tied to a base rate such as prime [3]. With prime at 7.00% [4], a variable 7(a) loan over $350,000 cannot exceed 10.0% [3]. On a variable 7(a) loan, the lender may require a different payment when the rate changes [2].
The 504 CDC piece carries a fixed rate pegged above the 10-year Treasury yield [1], which was 5.15% on October 19, 2026 [4]. NerdWallet puts typical 504 rates at about 5% to 7% [5]. The bank's 50% piece is priced separately by the bank.
| Financing | Rate assumed | Monthly payment | Total interest |
|---|---|---|---|
| 7(a), $1,800,000 at the variable cap, assuming 10% down | 10.0% [3] | $16,356.61 | $3,106,984.03 |
| 504 CDC piece, $800,000 | 5% [5] | $4,676.72 | $603,016.10 |
| 504 CDC piece, $800,000 | 7% [5] | $5,654.23 | $896,270.07 |
The 504 rows leave out the bank's $1,000,000 piece, whose rate the bank sets, so they are not a full comparison. The point is the shape: a 7(a) at the cap is a variable 10% on the whole amount, while 504 locks a fixed rate on 40% of the project. 504 fees total approximately 3% of the debt and can be financed [1]; the maximum 7(a) upfront fee on a loan this size is 3.5% of the SBA-backed portion up to $1 million plus 3.75% above that [6].
Rules only the 504 has: jobs and owner occupancy
Because the 504 is an economic development program, each project must create or retain one job opportunity per $95,000 the SBA backs. For small manufacturers, or projects that meet an energy goal, the bar is one job per $150,000 [6]. Projects can instead qualify under other economic development objectives [6].
The job rule on the $2,000,000 building
The CDC piece is $800,000. At one job per $95,000, the project needs about 8.4 job opportunities created or retained, or must meet another policy goal. If it cannot, the debenture is reduced to fit [6].
The 504 also requires you to use the property. NerdWallet notes the SBA requires real estate bought with 504 financing to be at least 51% owner-occupied, and 60% for new construction [7]. Speculation and rental real estate are not eligible [1].
How big each can go: the 504 limit is on the CDC piece only
The headline limits look similar, $5 million for a 7(a) loan [2] and $5.5 million for a 504 [1], but they measure different things. A 7(a) limit is the whole loan. A 504 limit is the CDC debenture, which is only about 40% of the project [6].
Under the SBA's rulebook, the 504 debenture is capped at $5,000,000 outstanding for each business and its affiliates, while small manufacturers and eligible energy projects can get up to $5,500,000 for each project [6]. Because the bank's 50% and your 10% sit on top, a single 504 project can finance a far larger building than a 7(a) loan alone.
For a 7(a), the SBA's own exposure tops out at $3.75 million in guaranties [3], which is 75% of a $5 million loan. If a project needs more, it can pair a 504 for the real estate with a 7(a) for everything else.
How New Jersey businesses use each program
SBA loan-level data shows how differently the two programs are used in New Jersey. In federal fiscal year 2025, NJ borrowers took 2,831 7(a) loans with a median of $150,000, and 83 504 loans with a median of $1,076,000 [8].
| Program and year | Loans | Total approved | Median loan |
|---|---|---|---|
| 7(a), FY2024 | 2,497 | $892.1 million | $150,000 |
| 7(a), FY2025 | 2,831 | $1.20 billion | $150,000 |
| 504, FY2024 | 93 | $139.4 million | $949,000 |
| 504, FY2025 | 83 | $137.5 million | $1,076,000 |
The pattern is clear: the 7(a) is the everyday program, and the 504 is for the big fixed-asset project. Among CDCs, Trenton Business Assistance Corporation made the most 504 loans to New Jersey borrowers from FY2024 through June 2026, with 155 [8]. The SBA's 504 page lets you find a CDC near you [1].
How to decide in three questions
- Is any of the money for working capital, inventory or buying a business? If yes, you need a 7(a), alone or alongside a 504.
- Is the main asset a building you will occupy or equipment with 10+ years of life? If yes, price a 504 for the fixed rate.
- Can the project meet the 504 job or policy goal, and can you wait for three parties to close? If not, a 7(a) is simpler.
Some projects use both: a 504 for the building and a 7(a) for the equipment and working capital to run it. Business Funders is not affiliated with the SBA; our quiz shows which products your numbers fit, with the cost of each in dollars.
