The short answer. Run Layer Cake with the SBA debt service loaded into Layer 1 before approaching the lender. Restate owner comp to market. Prepare three years of financials that reflect the restated numbers. Document use of proceeds with an incremental gross margin model showing how the loan pays for itself. Underwriters will restate anyway. Doing it first means you know what they will see and can decide whether to proceed.
Run Layer Cake Post-Financing First
Model the specific loan you want. Amount, rate, term, and monthly principal and interest payment. Load the monthly principal into Layer 1 MMP Debt Service sub-layer. Load the monthly interest into Layer 2 Fixed Cost Capacity.
Recalculate Layer 3, Layer 4, and Layer 5.
The new Breakeven Sales Volume is the number the business must hit to service the new debt on top of everything else. Compare against trailing-twelve-months revenue.
If TTM revenue exceeds the new Breakeven with 10 to 15 percent cushion, the loan is fundable. If it barely clears, the loan is fragile. If it does not clear, do not apply.
Restate Owner Comp Before The Underwriter Does
SBA underwriters restate owner comp to market as part of their cash flow analysis. They will see whatever the market rate is for your role at your business's scale.
If you have been undermarking (see the owner comp explainer), your reported EBITDA is overstated by the underpayment. The underwriter will remove that overstatement.
Do this yourself first. Take your actual draw. Subtract from market rate. That gap is the reported EBITDA overstatement. Recalculate your debt service coverage ratio against the restated EBITDA. If it still clears, the loan will underwrite. If it does not, the loan will be smaller than you were expecting or will require pricing changes.
Document Use of Proceeds
SBA lenders want to see a use-of-proceeds statement. Not a vague growth story. Specifics. Equipment purchase at a specific price. Real estate acquisition at a specific address. Debt refinance of a specific note.
For each use, model the incremental impact. Equipment: incremental capacity in billable hours or throughput multiplied by realized gross margin. Real estate: reduced rent expense as savings, plus any occupancy expansion revenue. Debt refinance: interest savings, monthly cash flow improvement, and reduced MMP burden.
The model should show that the proceeds fund incremental gross margin dollars sufficient to service the new debt with cushion. Underwriters expect to see this. Owners who show up without it either get declined or get talked into a smaller loan than they wanted.
Frequently Asked Questions
What is the difference between 7(a) and 504?
7(a) is general purpose (working capital, refinance, equipment, real estate) up to $5 million standalone or up to $10 million combined with 504 as of July 2026. 504 is specifically for real estate and major equipment, at typically lower rates but requiring 10 percent equity injection.
How long does an SBA loan take to close?
30 to 90 days depending on complexity. Real estate takes longer. Working capital is faster. The bank you work with matters. Some SBA-preferred lenders can close standard 7(a) in 30 to 45 days.
What is the interest rate on an SBA loan?
Variable, tied to prime plus 2 to 4 depending on facility, size, and term. As of mid-2026, that puts most SBA facilities at 9 to 12 percent. Fixed-rate options are available at slightly higher rates.
Can I get an SBA loan for an acquisition?
Yes, 7(a) is often used for small business acquisitions. See the acquisition explainer for the diligence sequence before applying.
