SBA 504 Loan Fees Explained: Every Fee Borrowers Pay (and Who Gets It)
The SBA 504 loan program offers some of the best terms in commercial lending — below-market fixed rates, long terms, and low down payments. But the fee structure confuses almost everyone. Multiple parties collect fees at different stages, and the total closing cost picture isn’t always clear until you’re staring at the settlement statement.
Let’s fix that. Here’s a complete breakdown of every fee you’ll encounter on an SBA 504 loan, based on SOP 50 10 8 effective June 1, 2025.
Understanding the 504 Loan Structure
Before we talk fees, you need to understand who’s involved:
- Third Party Lender (TPL) — Usually a bank providing the first mortgage (typically 50% of the project)
- Certified Development Company (CDC) — The SBA-authorized nonprofit that provides the 504 loan (typically 40% of the project)
- SBA — Guarantees the CDC’s debenture
- Central Servicing Agent (CSA) — Services the debenture payments
- Underwriter — Facilitates the debenture sale on Wall Street
- Borrower — You. Providing the equity injection (typically 10-20%) and paying most of the fees.
CDC Fees
1. CDC Processing Fee (Packaging Fee)
Amount: Up to 1.5% of the Net Debenture
This is what the CDC charges for packaging, processing, and underwriting your 504 loan application. Paid by the borrower to the CDC. This is typically the CDC’s primary revenue from the transaction.
2. CDC Closing Fee
Amount: Maximum of $10,000 — may be financed from debenture proceeds
The CDC may charge a reasonable closing fee to cover the expenses of in-house or outside legal counsel and miscellaneous closing costs. The key word is “reasonable” — it’s capped at $10,000 but should be tied to actual costs. This one can be rolled into the debenture, which is a nice break for borrowers.
3. CDC Servicing Fee (Monthly/Ongoing)
Amount:
- Minimum: 0.625% per year of unpaid principal balance
- Maximum: 2% per year
- Standard limits: Maximum 1.5% for rural areas, 1% for everywhere else without prior SBA approval
This is an ongoing fee paid by the borrower to the CDC for the life of the loan. It’s calculated on the unpaid principal balance and built into your monthly payment. The CDC earns this as long as the loan is outstanding.
4. Late Fees
Loan payments received after the 15th of each month may be subject to a late payment fee of 5% of the late payment or $100, whichever is greater. Collected by the CSA on behalf of the CDC.
5. Assumption Fee
Amount: Not to exceed 1% of the outstanding principal balance
If someone buys your business and assumes the 504 loan (with SBA’s written approval), the CDC charges this fee. Paid by the borrower (or buyer) to the CDC.
Central Servicing Agent (CSA) Fees
Initiation Fee
Set in accordance with the contract between the CSA and SBA. This is a one-time fee at the start of the loan.
Ongoing Fee
Also per the CSA-SBA contract. Built into the monthly debenture payment. You’ll see this as part of your total monthly obligation.
Underwriter’s Fees
The underwriter facilitates the sale of the SBA-guaranteed debenture on Wall Street. Different rates apply based on the debenture term:
20 and 25-Year Debentures
Upfront fee: 0.4% of the debenture amount. Paid by borrower to the underwriter.
10-Year Debentures
Upfront fee: 0.375% of the debenture amount. Paid by borrower to the underwriter.
These fees are one-time, paid at debenture funding.
SBA Fees
1. SBA Guaranty Fee (Up-Front, One-Time)
This is a one-time fee that varies by fiscal year. SBA publishes the current rate on sba.gov. Historically it has been in the range of 0.5% of the debenture amount, but always check the current fiscal year notice.
2. SBA Annual Fee (Ongoing)
An ongoing annual fee charged on the unpaid principal balance. The rate is adjusted annually by cohort year (based on when the individual loan was approved). This is part of your monthly payment obligation.
3. Participation Fee — Senior Lienholder
Amount: 0.50% of the senior mortgage loan — One-time fee
This fee applies to the Third Party Lender if they hold a senior lien position to SBA in the project. It can be paid by the Third Party Lender, the CDC, or the borrower — negotiation determines who bears this cost.
4. CDC Fee to SBA
Amount: 0.125% per year of the outstanding principal balance of the debenture
This is an ongoing fee that the CDC pays to SBA. The SOP is explicit: this fee must be paid from the servicing fees collected by the CDC and cannot be passed to borrowers through additional charges (for loans approved after 9/30/1996).
5. Debt Refinancing Without Expansion Supplemental Fee
If you’re using the 504 program to refinance debt without an expansion component, there’s an additional supplemental fee. The rate varies by fiscal year — check sba.gov for current notices.
Funding Fee
Amount: 0.25% of the Net Debenture Proceeds
This covers costs incurred by the trustee, fiscal agent, and transfer agent. It’s a one-time fee at debenture funding.
Borrower’s Deposit at Application
At the time of application, the CDC may require a deposit of $2,500 or 1% of the Net Debenture Proceeds, whichever is less.
The deposit rules:
- CDC or SBA declines the application: Full refund within 10 business days
- SBA approves the loan: Deposit may be applied toward the CDC processing fee
- Applicant withdraws before E-Tran Terms and Conditions issued: CDC may deduct reasonable and necessary costs incurred in packaging and processing (must be documented, cannot be a percentage of the loan). Remaining balance refunded within 10 business days.
Putting It All Together: Sample Fee Calculation
Let’s look at a typical 504 project with a $1,000,000 Net Debenture on a 25-year term:
| Fee | Rate | Amount | When Paid |
|---|---|---|---|
| CDC Processing Fee | Up to 1.5% | Up to $15,000 | At closing |
| CDC Closing Fee | Actual costs | Up to $10,000 | At closing (can be financed) |
| Underwriter Fee (25-yr) | 0.4% | $4,000 | At funding |
| SBA Guaranty Fee | ~0.5% (varies) | ~$5,000 | At funding |
| Funding Fee | 0.25% | $2,500 | At funding |
| Participation Fee (TPL) | 0.50% of TPL loan | Varies | One-time |
| Total Upfront (Approximate) | $36,500+ |
Ongoing annual fees:
- CDC Servicing: 0.625%–1% per year on declining balance
- SBA Annual Fee: Varies by cohort year on declining balance
- CSA Ongoing Fee: Per CSA-SBA contract
Fees That Cannot Be Passed to Borrowers
Be aware of what CDCs and lenders cannot charge you:
- Technology services fees (software, platforms, automated underwriting systems)
- CDC fee to SBA (0.125%/year) — must come from CDC servicing fee revenue
- Fees from professional services contractors working for the CDC
- Costs of licensing software used for loan document preparation or underwriting
How to Minimize Your 504 Loan Costs
- Negotiate the CDC processing fee. It’s “up to” 1.5% — some CDCs charge less, especially on larger debentures.
- Ask about the closing fee. $10,000 is the max, but if the CDC’s actual costs are $5,000, push for that number.
- Finance what you can. The CDC closing fee can be rolled into the debenture, reducing your out-of-pocket at closing.
- Shop CDCs. Servicing fees vary. The difference between 0.625% and 1% on a $1M debenture is $3,750 per year — that adds up over 25 years.
- Watch the participation fee. Negotiate with the Third Party Lender on who absorbs the 0.50% participation fee.
