Your SBA Rate Is 10.5%. Your Real Cost Of Capital Is Higher, And The Gap Is In The Fine Print.

The interest rate is the part of an SBA loan everyone shops, and it is not the part that hurts you.

Ask any first-time buyer what their SBA loan costs and they will quote you a rate. Right now that rate sits somewhere between 9% and 11.5% on most acquisition deals, driven by the base rate plus a lender spread the SBA caps by loan size. Fine. Shop it, get three quotes, negotiate the spread. But the rate is one line on a longer bill. The guaranty fee, the packaging cost, the closing costs, and the way those scale on bigger loans add up to real money, and they hit at the worst possible moment: closing, the same day you needed cash in the business. Buyers who only shop the rate get blindsided by the total. Here is the whole stack, so you are not one of them.

The Rate Is The Floor, Not The Cost

Your rate is base rate plus a capped lender spread, and that spread is negotiable.

Most SBA 7(a) acquisition loans use the WSJ Prime Rate as their base, which sat at 6.75% recently. On top of that, the lender adds a spread the SBA caps by loan size. For most acquisition loans over $350,000, the structure puts well-qualified buyers in that 9% to 11.5% band depending on credit, DSCR, and the lender's own pricing model. Two things buyers miss here. First, the spread is negotiated, not fixed, so your credit profile and the deal's debt coverage directly move your rate. Second, since March, lenders can also base variable loans on SOFR or Treasury rates instead of Prime, which means two lenders can quote the same deal differently. FOIA data has shown a spread of well over 100 basis points between the tightest and loosest lenders on similar acquisition deals. On a $1 million loan over 10 years, that gap is roughly $100,000 in total interest. That is your working capital cushion, decided by which lender you walked into first.

The Fees Nobody Quotes You

The guaranty fee and closing costs hit at closing, in cash, on top of your down payment.

This is where the real surprise lives. The SBA charges a guaranty fee on the guaranteed portion of the loan, and on larger loans it climbs into real numbers. Layer on packaging fees, closing costs, and the usual transaction expenses, and you are looking at costs that typically run a couple of points of the purchase price, separate from the rate entirely. I had a buyer last year who budgeted his 10% down to the dollar and nearly stalled at the table because he had not set aside for the guaranty fee and closing costs on top of it. The deal was fine. His cash plan was not. That is why the Bulletproof cash-in calculation never stops at the down payment. Your cash in is your down payment plus your working capital cushion plus closing costs, because all three come out of your pocket before the business pays you a dime.

Shop the rate all you want. The fees are what decide whether you have cash left on day one.

The Move

Budget total cost of capital, not the rate, and protect the working capital cushion above everything.

Here is how I would run it. Get three lender quotes and compare the full picture: rate, spread, guaranty fee, and closing costs, not just the headline number. Ask each lender which base rate they are using and what their all-in fees come to. Then build your cash-in budget the Bulletproof way: down payment, plus closing costs, plus a working capital cushion of at least three months of revenue. After 35 years of looking at these, the buyers who run out of money in month three almost never overpaid on the rate. They under budgeted the fees and raided the cushion to cover them. Do not be that buyer. You can model the full cash-in and the resulting cash flow at DealScorePro before you ever sit down with a lender, so the total cost is a plan instead of a surprise.

What This Means For You

Before you finalize any acquisition, build a cash-in budget that includes the guaranty fee, closing costs, and a three-month working capital cushion on top of your down payment. If covering the fees forces you to dip into the cushion, the deal is underfunded, and underfunded is how good businesses fail in the first 90 days.
