The SBA runs two flagship loan programs that borrowers constantly confuse because they solve different problems. The 504 is a fixed-asset machine: three parties (bank, CDC, you) finance real estate and heavy equipment at a long-term fixed rate. The 7(a) is the general-purpose workhorse: one lender loan, SBA-guaranteed, usable for almost anything including working capital. This hub owns the decision: the full comparison table, scenario routing, and the pair-both-programs play — with live rate tables deliberately kept on the dedicated pages (7(a) rates & fees · 504 rates & fees) rather than duplicated here.
General information, not a loan offer. Program rules per SBA SOP 50 10 (current version) and SBA.gov.
| SBA 504 | SBA 7(a) | |
|---|---|---|
| Purpose | Fixed assets only: owner-occupied real estate, heavy equipment | Almost any business purpose: real estate, equipment, working capital, business acquisition, refinance |
| Structure | Three parts: bank ~50% + CDC/SBA debenture ~40% + borrower ~10% | One loan from an SBA lender, up to 85–90% SBA-guaranteed |
| Maximum | $5M CDC portion ($5.5M for manufacturers / energy projects) → projects to ~$13M+ | $5M total loan |
| Down payment / equity | 10% standard; 15% single-purpose property; 20% if also a startup | Typically 10–20% by deal (10% common for real estate) |
| Rate | CDC portion fixed for the full term (debenture rate); bank portion negotiated (often fixed or variable) | Mostly variable (prime + capped spread); fixed available |
| Terms | 10 / 20 / 25 years on the CDC note (fully amortizing, no balloon) | Up to 25 years (real estate), 10 years (equipment/other), 7 years (working capital) |
| Working capital | ❌ Not eligible | ✅ Eligible |
| Prepayment | Penalty on CDC portion, declining over the first 10 years (25/20-yr terms) | Penalty only on terms >15 years, first 3 years (5-3-1%) |
| Occupancy | Must be owner-occupied (51% existing / 60% new construction) | Owner-occupied required for real estate purchases |
| Speed | Slower — two lenders + SBA debenture cycle (60–90+ days typical) | Faster (45–90 days typical; Preferred Lenders decide in-house) |
| Job creation | Job-creation/retention or community-development goals apply | No job test |
Nothing stops an eligible business from using both: a 504 for the building (fixed-rate, low equity) plus a 7(a) for the equipment package, fit-out, and working capital the 504 cannot fund (pereff.com raises this pairing in the property SERP; lenders structure it routinely). The sequence matters — discuss the pair with both lenders before either application, so neither loan’s underwriting is surprised by the other.
What’s the difference between an SBA 504 and a 7(a) loan? Structure and purpose — bside.org’s comparison is literally titled “504 VS 7(A): WHAT’S THE DIFFERENCE?” The 504 is a three-part, fixed-asset-only financing with a fixed-rate CDC portion; the 7(a) is a single guaranteed loan for nearly any business purpose, usually at a variable rate.
Which SBA loan is right for my business? The framing question of both NerdWallet’s and the US Chamber’s comparison pages — answered by your use of funds: fixed assets only → 504; anything broader, faster, or mixed → 7(a); property deals and startups have their own cuts in this cluster (links above).
Can an SBA 504 loan be used for working capital? No. NerdWallet states it flatly: if you need anything other than real estate or equipment, “an SBA 7(a) loan is your best bet.” The 504’s eligible-use list is fixed assets (plus soft costs and limited refinance), full stop.
How much down payment does an SBA 504 loan require? 10% of project cost in the standard structure (the borrower slice of the 50/40/10 split the US Chamber explains) — rising to 15% for single-purpose properties and 20% when a startup buys a single-purpose asset.
How much can I borrow under each program? 7(a): up to $5 million. 504: the CDC/SBA portion caps at $5 million ($5.5 million for manufacturers and energy projects), which supports total projects well above $12 million when the bank’s 50% is counted (NerdWallet’s comparison table).
