Choose an SBA 504 loan if you are buying or building owner-occupied real estate or long-life equipment and want a fixed rate on up to 40% of the project with as little as 10% down. Choose an SBA 7(a) loan for nearly everything else: working capital, buying a business, inventory, refinancing, or a project that mixes several uses.
Both programs are backed by the U.S. Small Business Administration, and both are made through private lenders. The difference is in how each loan is built and what it is allowed to pay for. The figures below reflect SBA's SOP 50 10 8.1, effective October 1, 2026, and the SBA fee schedule for fiscal year 2027 (October 1, 2026 through September 30, 2027).
How do SBA 7(a) and 504 loans compare side by side?
| SBA 7(a) | SBA 504 | |
|---|---|---|
| Maximum loan | $5 million | $5 million SBA debenture ($5.5 million for small manufacturers and certain energy projects), plus the bank's loan on top |
| Who lends | One bank or lender, with an SBA guaranty of 85% (loans of $150,000 or less) or 75% (larger loans) | A bank (about 50% of the project) plus a Certified Development Company, or CDC (up to 40%) |
| Minimum down payment | Set by the lender for most existing businesses; 10% required for startups and business purchases | 10% standard; 15% for new businesses or special-purpose property; 20% for both |
| Eligible uses | Working capital, equipment, real estate, business acquisition, refinancing, inventory | Real estate, construction, and machinery with at least a 10-year useful life. No working capital |
| Rate type | Fixed or variable, capped at a spread over prime | Debenture fixed for the full term; bank portion negotiated separately |
| Maximum rate | Prime + 3% on loans over $350,000 (higher spreads on smaller loans) | Debenture set by the market for long-term Treasury debt |
| Terms | Up to 10 years for working capital and equipment, 25 years for real estate | 10, 20, or 25 years |
| Job requirement | None | One job created or retained per $95,000 of SBA debenture ($150,000 for small manufacturers), or another public-policy goal |
The short version of the table: 7(a) is the flexible, general-purpose program. 504 is a narrower tool built for fixed assets, and it rewards that narrowness with lower down payments and a long fixed rate.
How is an SBA 504 loan structured?
A 504 loan is three pieces of money stacked on one project:
- The bank's first mortgage. A conventional lender funds at least 50% of the project and takes the first lien.
- The CDC debenture. A Certified Development Company funds up to 40% through a debenture that SBA guarantees in full. It sits in second position.
- Your contribution. You bring at least 10%.
When the business is two years old or younger, or the property is limited or special purpose (hotels, car washes, gas stations, medical facilities, and similar), the SBA share drops to 35% and your contribution rises to 15%. When both apply, the split is 50/30/20.
Because the debenture is sold to investors on the bond market, its rate is pegged to long-term Treasury yields and fixed for the full term. In September 2026, 504 debentures priced at roughly 6.5% for 10, 20, and 25-year terms, fees included. That rate changes every month, so treat it as a snapshot, not a quote.
What does the same building cost under each program?
Here is a hypothetical. Say a dental practice that has operated for six years wants to buy a $2,000,000 office building it will fully occupy.
Under SBA 504:
- Down payment: 10% = $200,000
- Bank first mortgage: 50% = $1,000,000. Assume 7.25% on a 25-year amortization = about $7,228 a month
- CDC debenture: 40% = $800,000. Assume 6.50% fixed for 25 years = about $5,402 a month
- Combined payment: about $12,630 a month
Under SBA 7(a):
- Down payment: assume the lender asks for 10% = $200,000
- Loan: $1,800,000. Assume 9.50% (prime plus 2.5% with prime at 7%) on a 25-year term = about $15,727 a month
With these assumptions, 504 comes out about $3,100 a month lower, or roughly $37,000 a year. The gap comes almost entirely from the rate on the SBA-backed piece.
Upfront costs differ too. Under the FY2027 fee schedule, the SBA guaranty fee on this 7(a) loan would be about $48,125: 3.5% of the first $1 million guaranteed plus 3.75% of the remaining $350,000 guaranteed on a 75% guaranty. On the 504 side, SBA estimates total debenture fees at about 3% of the debenture (roughly $24,000 here), usually financed into the loan, plus a one-time 0.5% fee on the bank's first mortgage ($5,000) and the bank's own closing costs.
Your actual rates will differ. The point of the example is the structure: on real estate, the 504's fixed debenture usually beats a 7(a) loan priced off prime, especially for owners who plan to keep the building for a decade or more.
When is an SBA 7(a) loan the better choice?
Pick 7(a) when any of these are true:
- You need working capital, inventory, or a line of credit. 504 can't fund any of them.
- You are buying a business. Change-of-ownership loans run through 7(a), with their own rules on equity, valuation, and cash flow coverage. See our guide to financing a business acquisition.
- The project mixes uses. A 7(a) loan can cover a building, equipment, and operating cash in one note.
- You need speed and simplicity. 7(a) has one lender and one closing. 504 requires a bank, a CDC, and a debenture sale, and it often needs interim financing until the debenture funds.
- The amount is small. Loans of $350,000 or less can be processed as 7(a) Small loans with lighter documentation, and SBA Express loans run up to $500,000.
- You want to refinance business debt that doesn't fit 504's refinancing rules.
When is an SBA 504 loan the better choice?
Pick 504 when:
- The project is mostly real estate or heavy equipment with a useful life of 10 years or more.
- You want a fixed rate for 20 or 25 years on a large share of the financing.
- You want to keep cash in the business. Ten percent down on a $2 million building leaves $200,000 or more in your account compared with a conventional commercial mortgage, which often requires 20% to 25%.
- The project is large. The bank's 50% share doesn't count against SBA's $5 million limit, so a 504 project can total well over $10 million.
- You are a manufacturer. Small manufacturers qualify for up to $5.5 million per project and a looser jobs test of $150,000 per job. For FY2027, SBA also waives 504 upfront and annual fees for manufacturers, certain food supply-chain businesses, and rural businesses on its debt refinancing programs.
For equipment alone, compare 504 against dedicated equipment financing. It closes faster and needs less paperwork, though the rate is usually higher.
Can you use both programs on the same deal?
Yes, and it is common. A buyer acquiring a business that comes with its building might use a 504 loan for the real estate and a 7(a) loan for the business itself, the goodwill, and working capital. SBA requires the 7(a) loan to be approved first when the two are paired, and the combined SBA exposure is subject to the program limits. Under SOP 50 10 8.1, a 504 loan cannot be blended into a single acquisition note. It has to be a separate loan.
What changed in the SBA rules for 2026?
A few changes affect both programs:
- Ownership and citizenship. Since March 1, 2026, 100% of a business's direct and indirect owners must be U.S. citizens or U.S. nationals whose principal residence is in the United States. Lawful permanent residents no longer qualify as owners. SOP 50 10 8.1 keeps this rule.
- New SOP. SOP 50 10 8.1 takes effect October 1, 2026. It reorganizes 7(a) rules into new appendices and rewrites the change-of-ownership rules. For 504, the jobs benchmark is now one job per $95,000 of debenture.
- FY2027 fees. 7(a) upfront guaranty fees run 2% to 3.75% of the guaranteed portion depending on loan size, and they are waived on 7(a) loans of $700,000 or less to manufacturers, certain food supply-chain businesses, and rural businesses. The 504 upfront guaranty fee is 0.5%, with an annual service fee of 0.203%.
How do you decide?
Start with the use of funds. If the money is going into a building or long-life equipment you will occupy and use, price out a 504. If any meaningful share is for working capital, an acquisition, or inventory, 7(a) is usually the only SBA option that fits, possibly alongside a 504.
