SBA 504 Loan Structure: Two Separate Loan Components
Every SBA 504 transaction involves two separate loans with independent financial terms. Understanding both is essential to evaluating the true cost and structure of your financing.
- Bank / First-Lien Loan (50%): Funded by a private bank or credit union at a rate and terms negotiated directly between the borrower and the bank. May be variable or fixed rate. The bank sets its own fees, prepayment terms, and underwriting requirements.
- CDC / SBA Debenture (40%): Funded through a Certified Development Company (CDC) via an SBA-guaranteed debenture sold to investors. The rate is fully fixed for the life of the loan and set at the time of closing. Fees are standardized by the SBA. Terms are 10, 20, or 25 years.
This page covers both components — the CDC debenture terms in full detail, and the standard parameters for the bank's first-lien portion.
The 504 Funding Structure
50%
Bank First Lien · Variable or Fixed
40%
CDC Debenture · Fixed Rate
Special-use properties: 15% equity. Start-up businesses: 20% equity. Percentages based on total project cost (purchase price + eligible soft costs).
CDC Debenture Amount Limits
The SBA caps the CDC debenture portion (40% second-lien) based on the qualifying goal the project serves. There is no SBA cap on the total project size — the bank's 50% first-lien portion is uncapped.
$5M
Max CDC Debenture
Applies to most businesses meeting the job creation or retention goal: 1 job per $90,000 of SBA debenture.
Manufacturers & Green Energy
$5.5M
Max CDC Debenture
For NAICS sectors 31–33 manufacturers (1 job per $140K) and projects meeting SBA energy efficiency or renewable energy public policy goals.
No Cap
On Bank Portion
The bank's 50% first-lien loan is uncapped by the SBA. Large projects ($10M, $20M+) are eligible — the CDC debenture cap applies only to the SBA-funded portion.
Example: A $12M manufacturing facility purchase: bank funds $6M (50%), CDC debentures $5.5M (46%), borrower contributes $500K (4%). The SBA debenture cap is $5.5M — the remaining funding gap is covered by a larger bank portion or additional borrower equity.
Down Payment & Equity Requirements
The borrower's minimum equity contribution depends on the property type and the business's operating history. These requirements may stack — a start-up purchasing a special-use property uses the highest applicable threshold.
10%
Standard Projects
Most owner-occupied commercial real estate purchases, construction, and renovation projects. Eligible businesses with ≥ 2 years operating history.
15%
Special-Use Properties
Properties with limited alternative use — gas stations, hotels/motels, car washes, car dealerships, golf courses, marinas, and similar single-purpose facilities.
20%
Start-Up Businesses
Businesses operating for fewer than 2 years at the time of application. If a start-up is also purchasing a special-use property, 20% applies (the higher threshold governs).
Equity injection sources: The borrower's equity contribution may come from personal savings, business retained earnings, a gift (with proper documentation), or — under certain conditions — a seller note subordinated to both the bank and CDC liens. The equity must be verified and confirmed at closing.
Interest Rate Structure
CDC Debenture Rate — Fixed
- Fixed for the entire loan term — rate does not change after closing
- Pegged to the yield of U.S. Treasury notes with a maturity approximating the debenture term
- A spread of approximately 50–130 basis points is added to cover SBA program costs
- Set at the time the debenture is sold to investors — typically at or near loan closing
- Longer debenture terms (20-yr, 25-yr) are benchmarked to the 10-year Treasury
- The effective rate the borrower pays is slightly higher than the debenture rate due to annual ongoing fees
Bank First-Lien Rate — Negotiated
- Variable or fixed — negotiated between the borrower and the bank
- Variable rates typically tied to Prime, SOFR, or another market index
- No SBA-mandated rate ceiling on the bank's first-lien portion
- Bank may offer a 5- or 10-year fixed period with a reset — or fully fixed for the term
- Bank rate is independent of the CDC debenture rate
- CLD negotiates bank terms across multiple lenders to obtain the best available rate

Debenture Term Options
Borrowers choose among three debenture term lengths. The term selection affects both the monthly payment size and the prepayment penalty schedule. The bank's first-lien loan must have a minimum term of 10 years and is often matched to the debenture term.
10
Year Debenture
Shorter term, higher monthly payments, faster equity build-up. Prepayment penalty expires after year 5. Best for businesses with strong cash flow seeking lower total interest cost.
20
Year Debenture
Most common term for commercial real estate. Balances payment size and total cost. Prepayment penalty expires after year 10. Bank minimum: 10 years.
25
Year Debenture
Lowest monthly payment — maximizes cash flow. Available for owner-occupied real estate. Prepayment penalty expires after year 10. Highest total interest cost over life of loan.
Term vs. payment: On a $2M CDC debenture at a 6% fixed rate, the 25-year term reduces monthly payment by approximately $900/month vs. the 20-year term. Run the payment scenario for your specific loan size with your CLD loan officer to determine which term optimizes your cash flow.
SBA 504 Fee Structure
SBA 504 fees apply to the CDC debenture portion only. All upfront fees are typically financed into the debenture — the borrower does not pay them out of pocket at closing. The effective interest rate the borrower pays is slightly higher than the debenture note rate due to the ongoing service fee.
Upfront Fees (Financed into Debenture)
~1.5%of Deb.
CDC Processing Fee
Charged by the Certified Development Company for originating and processing the debenture. Financed into the debenture — not paid out of pocket. Exact percentage may vary slightly by CDC.
~0.5%of Deb.
SBA Guarantee Fee
The SBA's upfront guarantee fee on the debenture. Financed into the debenture. Compensates the SBA for providing the guarantee that enables the debenture to be sold to investors at a competitive rate.
~0.4%of Deb.
Underwriting / Funding Fee
Charged by the Central Servicing Agent (CSA) for processing, underwriting, and funding the debenture. Financed into the debenture at closing.
~0.25%of Deb.
Third-Party Participation Fee
A one-time fee charged to the participating bank lender for the bank's involvement in the 504 structure. Typically passed to the borrower — check with your lender whether this is included in their closing costs or billed separately.
Annual Ongoing Service Fee
~0.643%per year
Annual Servicing Fee (CDC Debenture)
Charged annually on the outstanding CDC debenture balance for the life of the loan. Collected by the Central Servicing Agent and distributed among the CDC, SBA, and CSA. Decreases over time as the debenture amortizes. This fee is effectively embedded in the borrower's monthly payment.
Effective vs. note rate: The debenture note rate (pegged to Treasury) is the rate at which the SBA sells the debenture to bond investors. The effective rate to the borrower is approximately 20–40 basis points higher than the note rate due to the ongoing annual service fee. Fee percentages above are representative — confirm exact rates with your CDC at the time of application.
Prepayment Penalty Schedule
The CDC debenture carries a declining prepayment penalty during the first half of the loan term. The bank's first-lien loan has a separately negotiated prepayment provision — the schedules below apply to the CDC debenture only.
20-Year Debenture — Prepayment Schedule
Years 11–20: No prepayment penalty.
10-Year Debenture — Prepayment Schedule
Years 6–10: No prepayment penalty.
25-Year Debenture — Prepayment Schedule
The 25-year debenture uses the same 10-9-8...1% declining schedule as the 20-year debenture, with no penalty from year 11 through maturity.
Years 11–25: No prepayment penalty — a 15-year penalty-free window on a 25-year loan.

Job Creation & Public Policy Goals
Every SBA 504 project must meet at least one of the program's qualifying goals — either a job creation or retention threshold, or a public policy objective. Meeting a public policy goal provides an alternative path to qualification when the job creation threshold cannot be met.
Job Creation / Retention Requirements
- Most businesses: Create or retain 1 job per $90,000 of SBA debenture
- Manufacturers (NAICS 31–33): 1 job per $140,000 of SBA debenture
- Jobs measured over a 2-year period following loan closing
- Both new job creation and retention of existing jobs at risk of loss qualify
- Full-time equivalent (FTE) calculation: two part-time positions = one FTE
Public Policy Goals (Alternative Path)
- Business district revitalization
- Expansion of exports
- Expansion of minority business development
- Rural development
- Increasing productivity and competitiveness
- Veteran-owned and woman-owned small business expansion
- Energy efficiency or renewable energy projects
- Restructuring due to federally mandated standards or budget cutbacks
Collateral & Personal Guaranty
Collateral
- The project assets being financed serve as primary collateral — the bank takes a first lien; the CDC takes a second lien
- All assets must be fully insured (property & casualty) throughout the loan term
- The bank may require additional collateral (personal real estate, other business assets) at their discretion
- The CDC's lien is subordinate to the bank's — in foreclosure, the bank is made whole first
- The SBA guarantee on the debenture protects CDC investors, not the borrower
Personal Guaranty
- Personal guaranty required from all owners with ≥ 20% equity interest — no exceptions
- Guarantors are jointly and severally liable for the full outstanding balance
- Both the bank and the CDC require separate personal guaranties
- Guaranty obligations survive the sale of the business unless specifically released in writing
- Spousal guaranties may be required if marital assets serve as collateral

SBA 504 Terms FAQs
The SBA caps the CDC debenture (the 40% SBA-funded portion) at $5,000,000 for most businesses and $5,500,000 for manufacturers and green energy projects. There is no SBA cap on total project size — the bank's 50% first-lien loan is uncapped. On a standard project: a $12.5M property purchase could be structured as $6.25M bank / $5M CDC / $1.25M borrower equity (50/40/10).
The CDC debenture rate is fixed and set at the time the debenture is sold to bond investors — typically at or near loan closing. The rate is pegged to the current yield on U.S. Treasury notes with a maturity approximating the debenture term (5-year Treasury for 10-year debentures; 10-year Treasury for 20- and 25-year debentures), plus a spread covering program costs. The bank's 50% first-lien portion has a separate, independently negotiated rate that may be variable or fixed. View current indicative rates on our
rates page.
The CDC debenture is available in three terms: 10 years, 20 years, or 25 years. The 25-year option offers the lowest monthly payment but the highest total interest cost over the life of the loan. The 10-year option offers the fastest payoff and lowest total interest but the highest monthly payment. The 20-year term is the most common choice, balancing payment size and total cost. All terms are fully amortizing — no balloon payment on the debenture.
The SBA 504 CDC debenture carries several standardized fees: a CDC processing fee (~1.5%), SBA guarantee fee (~0.5%), and underwriting/funding fee (~0.4%) — all upfront and financed into the debenture so the borrower does not pay them out of pocket. An annual ongoing service fee (~0.643% of the outstanding debenture balance) is collected for the life of the loan and embedded in the monthly payment. The bank's first-lien portion carries its own separate origination and closing fees negotiated with the bank.
The CDC debenture carries a declining prepayment penalty during the first half of the term. For 20- and 25-year debentures: 10% in year 1, declining by 1% per year through year 10, then no penalty. For 10-year debentures: 5% in year 1 through 1% in year 5, then no penalty. The penalty applies to the outstanding CDC debenture balance at the time of prepayment. The bank's first-lien loan has a separately negotiated prepayment provision. Use our
SBA 504 Prepayment Calculator for a precise estimate.
Most SBA 504 projects must create or retain 1 job per $90,000 of SBA debenture within 2 years of loan closing. Manufacturers (NAICS 31–33) have a higher threshold of 1 job per $140,000. As an alternative, projects may qualify by meeting a public policy goal — such as business district revitalization, rural development, export expansion, or veteran/women-owned business expansion — in lieu of the job creation threshold.
