SBA 504 Loan Requirements, Rates & Calculator Guide 2025
SBA 504 Loan Requirements, Rates & Calculator Guide 2025
The SBA 504 loan is one of the most powerful financing tools available to growing small businesses. It offers long-term, fixed-rate financing for major fixed assets — specifically commercial real estate and heavy equipment — at interest rates that are typically below conventional bank rates.
If you're buying a building, expanding a facility, or investing in significant equipment, the 504 is often the best option available.
What Is the SBA 504 Loan?
The SBA 504 loan is a three-party transaction:
- The bank or conventional lender provides 50% of the project cost
- The Certified Development Company (CDC) provides 40% (backed by SBA guarantee)
- The borrower contributes 10% as a down payment (sometimes 15–20% for startups or special-purpose properties)
This structure gives borrowers long-term fixed-rate financing with a small down payment — making it particularly attractive for businesses that want to build equity in commercial real estate rather than paying rent.
SBA 504 Loan Amounts
- Standard maximum: $5.5 million for most businesses
- Manufacturing businesses: Up to $5.5 million per project (higher limits may apply)
- Energy-efficient projects: Up to $5.5 million per project
- No maximum limit on total project cost — the 504 covers 40% up to the cap amounts above
The bank provides 50% of the project cost with no SBA-set cap, so a $10 million building purchase can be financed with a $5M bank loan + $4M CDC loan + $1M down payment.
SBA 504 Loan Requirements
For the Business
- Net worth: Must be under $20 million at application
- Average net income: Must be under $6.5 million (after taxes) over the prior two years
- For-profit status required
- Business must operate in the U.S. or its territories
- No current government loan delinquency
- Owners with 20%+ stake must sign personal guarantee
For the Project
- Eligible uses: Land purchase, building purchase or construction, renovation, machinery and equipment with 10+ year useful life
- Ineligible uses: Working capital, inventory, debt refinancing (with some exceptions), speculative real estate, investment properties
- Job creation requirement: Generally must create or retain one job per $75,000 of 504 loan ($120,000 for manufacturers)
- Business must occupy 51%+ of purchased property (60%+ for new construction)
Credit Score
The SBA doesn't set a minimum credit score for 504 loans, but the bank providing 50% of financing has its own requirements. Most banks want 650+, with many preferring 680+ for real estate loans. The CDC reviews the complete application holistically.
Years in Business
There's no SBA-mandated minimum for 504 loans, but most bank partners want 2+ years of operating history. Startups can sometimes qualify with strong equity and solid business plans, but it's more challenging.
SBA 504 Loan Interest Rates
The 504 loan has two rate components:
CDC/SBA Portion (40% of project)
Fixed rate based on the current 10-year or 20-year Treasury rate plus a spread. As of early 2025, effective rates are approximately:
- 10-year term (equipment): ~6.0–6.5%
- 20-year term (real estate): ~6.5–7.0%
- 25-year term (real estate): ~6.5–7.0%
These rates are fixed for the life of the loan — a major advantage when conventional rates are higher or volatile.
Bank Portion (50% of project)
The bank sets its own rate on its 50% portion. This is typically a variable rate or a fixed rate for 5–10 years that resets. Negotiating favorable terms on the bank portion is important to your overall cost.
How to Estimate Your 504 Loan Payment
As a rough calculator for the SBA/CDC portion:
Example: $1 million commercial real estate purchase
- Bank loan (50%): $500,000 — bank sets terms
- CDC/SBA loan (40%): $400,000 at ~6.5% fixed for 20 years
- Down payment (10%): $100,000
For the $400,000 at 6.5% over 20 years: approximately $2,982/month
For the $500,000 bank portion at a variable rate (say 7.5% over 10 years): approximately $5,934/month
Total monthly payment: approximately $8,916/month on a $1M building
These are illustrative estimates — your actual rates and terms will vary based on creditworthiness, property type, and lender.
SBA 504 vs. Conventional Commercial Real Estate Loan
| Feature | SBA 504 | Conventional CRE Loan | |---------|---------|----------------------| | Down payment | 10% | 20–30% | | CDC rate (40%) | Fixed for 20–25 years | N/A | | Total LTV | 90% | 70–80% | | SBA guarantee | Yes (on CDC portion) | No | | Eligible uses | Real estate + equipment | Real estate primarily | | Processing time | 60–90 days | 30–60 days | | Fees | SBA fees + closing costs | Closing costs |
The lower down payment requirement is often the decisive factor — businesses preserve capital for operations while building equity in the property.
How to Apply for an SBA 504 Loan
Step 1: Find a CDC (Certified Development Company) in your state. The SBA maintains a list at sba.gov.
Step 2: The CDC will help you find a participating bank for the 50% conventional loan portion.
Step 3: Gather documents: business and personal tax returns (3 years), business financial statements, personal financial statement, property information, purchase agreement.
Step 4: Both the bank and CDC review separately. The CDC submits to the SBA for the final guarantee.
Step 5: Closing involves two loan closings — the bank loan and the CDC/SBA debenture. The CDC handles the SBA portion.
Key Takeaways
- SBA 504 is ideal for commercial real estate and major equipment purchases
- 10% down payment (vs. 20–30% conventional) is the biggest advantage
- The CDC/SBA portion has a fixed interest rate for 20–25 years
- Must create/retain jobs and business must occupy 51%+ of purchased property
- Combined with a bank loan, total financing can exceed $10 million for large projects
Frequently Asked Questions
Can I use an SBA 504 loan to buy a business?
No — the SBA 504 is specifically for fixed assets (real estate and equipment). To buy a business, use the SBA 7(a) program. However, if the acquisition includes real estate, a 504 can be used for that portion alongside a 7(a) for other acquisition costs.
How long does SBA 504 approval take?
Typically 60–90 days from application to closing. The process involves bank approval plus CDC/SBA review, which adds time compared to conventional loans.
What is a CDC?
A Certified Development Company (CDC) is a nonprofit organization certified by the SBA to administer the 504 loan program. CDCs work as your partner throughout the process, submitting the SBA guarantee request and handling the debenture closing.
