This post compares small business financing rates across the main options available for an acquisition — SBA loans, conventional bank loans, and seller financing — so you can weigh the real cost of each rather than just the headline number.
- SBA loans generally offer the most competitive rates for individual buyers, given the government guarantee.
- Conventional loan rates vary more, sometimes higher, occasionally competitive for exceptionally strong applicants.
- Seller financing rates are negotiated directly and vary widely deal to deal.
- The lowest headline rate isn't always the best overall deal once term, fees, and flexibility are considered.
| SBA 7(a) Loan | Conventional Bank Loan | Seller Financing | |
|---|---|---|---|
| Typical rate basis | Prime + lender spread, SBA-capped | Market rate, lender-set | Negotiated directly with seller |
| Down payment | 10-20% | 20-30%+ | Varies, often supplemental |
| Repayment term | Up to 10 years (25 with real estate) | Often 5-7 years | Negotiated, often 3-7 years |
| Approval speed | Slower, more documentation | Can be faster | Fastest, direct negotiation |
Why Do SBA Loans Generally Offer the Best Rates?
The SBA's 7(a) loan program page program's government guarantee substantially reduces the lender's risk, which translates into more competitive rates and terms than a lender would typically offer without that backing. Rates are capped at SBA-set maximums tied to the prime rate plus a lender spread, which keeps them within a predictable, generally favorable range compared to unsecured or higher-risk conventional financing options.
How Do Conventional Bank Loan Rates Compare?
Conventional rates vary more widely than SBA rates, since they're set entirely by the individual lender's own risk assessment without a government guarantee moderating the terms. A buyer with exceptional personal credit acquiring a very strong, well-established business can sometimes secure competitive conventional terms, occasionally even better than SBA rates in specific cases — but this represents a smaller share of buyers than those better served by SBA financing's more consistently favorable terms.
How Do Seller Financing Rates Work?
Seller financing rates are negotiated directly between buyer and seller rather than set by a formal lending institution, which means they vary considerably deal to deal based on the seller's own expectations and risk tolerance. Some sellers charge rates comparable to what a bank would, while others are more flexible, particularly if they're motivated by tax planning or a desire for a smoother, faster transition rather than treating the financing purely as an investment return.
Does the Lowest Rate Always Win?
Not necessarily. A loan with a slightly higher rate but a longer repayment term can mean lower monthly payments and better cash flow flexibility for the business than a lower-rate loan with a shorter term. Fees, prepayment penalties, and how quickly a lender can actually close all factor into the real cost and value of financing beyond the headline interest rate alone — comparing the full terms, not just the rate, gives you a more accurate picture of which option genuinely serves you best.
How Should You Actually Compare Your Options?
Get concrete quotes reflecting your specific situation from at least an SBA lender and, if relevant, a conventional bank, and understand what seller financing terms might realistically be available for your target deal. According to IBBA and M&A Source's Q1 2026 Market Pulse survey, realistic pricing typically runs 2.0x SDE to 4.0x EBITDA — grounding your financing comparison in a realistic purchase price, rather than a hoped-for lower number, gives you an accurate basis for comparing what each financing option would actually cost you in practice.
How Do Fees Factor Into a True Cost Comparison?
SBA loans carry a guarantee fee that's often rolled into the financed amount, effectively raising the true cost slightly above the stated interest rate alone. Conventional loans may carry origination fees that vary by lender. Seller financing typically carries the fewest additional fees, since there's no institutional lender involved, though the negotiated rate itself is where the seller's real compensation for the risk shows up. Ask for a full breakdown of all fees, not just the headline rate, when comparing any two financing options side by side.
Request a full amortization schedule and complete fee disclosure from any lender before signing anything, so you're comparing genuinely equivalent numbers rather than headline rates that can hide meaningfully different total costs over the life of the loan.
There's rarely a single objectively "best" rate across every situation — the right choice depends on your specific cash position, how much monthly flexibility you need, and how the seller feels about carrying part of the financing themselves.

FAQ
1. Which financing option typically has the lowest rate?
SBA loans generally offer the most competitive rates for individual buyers, thanks to the government guarantee reducing lender risk.
2. Are conventional bank loan rates always higher than SBA rates?
Often, though not always — a buyer with exceptional credit and a very strong target business can sometimes secure competitive conventional terms.
3. What rate should you expect from seller financing?
Seller financing rates vary widely and are negotiated directly, often falling somewhere between what a bank would charge and a rate reflecting the seller's own risk tolerance.
4. Does a lower rate always mean a better deal overall?
Not necessarily — repayment term, fees, and flexibility all factor into the real cost of financing beyond just the headline interest rate.
