Key Takeaways
Loan sizes: a 7(a) loan can reach $5 million; the average SBA microloan is about $13,000 and the maximum is $50,000 (SBA program pages, 2026).
504 loans: available only through Certified Development Companies, at fixed rates over 10, 20 or 25 years, and cannot fund working capital or inventory.
SBA Express: caps at $500,000 with a 50% guarantee, against 85% for a 7(a) Small loan of $150,000 or less.
504 job test: a project must create or retain one job per $95,000 SBA guarantees, or per $150,000 for small manufacturers and energy projects.
Collateral: SBA requires none on 7(a) Small loans of $50,000 or less.
The $350,000 line: a 7(a) Small loan increased above $350,000 becomes a Standard 7(a) loan.
What Should You Decide Before Choosing an SBA Loan?
Decide what the money will buy before you decide how much to borrow. Three kinds of need cover most requests: assets that outlast the loan, cash that rises and falls, and a mixed or modest need. Each points to a different SBA program, and the asset narrows the field before size or speed do.
On its 7(a) loans page, SBA says "Your lender will help you figure out which type of loan is best suited for your needs." That helps, but a lender recommends from the channels it works in. 504 loans are available "exclusively through Certified Development Companies," and microloans come only through SBA-approved intermediaries. Knowing which program fits lets you find the right door first.
Assets that outlast the loan = land, buildings and machinery with at least ten years of useful life left. These belong in the 504 program, which lends at a fixed rate over 10, 20 or 25 years and cannot fund working capital or inventory.
Cash that rises and falls = stock and receivables that turn back into cash. These suit a revolving line. CAPLines serve short-term and cyclical needs, and the 7(a) Working Capital Pilot offers monitored lines up to $5 million over 60 months.
A mixed or modest need = equipment, a fit-out, working capital and a change of ownership in one 7(a) loan, which SBA says covers machinery "including AI-related expenses." Below $50,000, a microloan, which averages about $13,000, can buy inventory and equipment, but not real estate, and it cannot repay existing debt.
The asset sets the shortlist. Size and timing choose from it.
What Are the Types of SBA Loans for Small Businesses?
The main types of SBA loans for small businesses are Standard 7(a), 7(a) Small, SBA Express, 504, microloans and CAPLines. They differ most in ceiling, term and fit. The table puts the six side by side, with limits taken from SBA's program pages, its lending rulebook and the 504 regulation.
Program | Maximum | Longest term | Best fit |
Standard 7(a) | $5 million | 10 years; 25 for real estate | Larger, mixed needs |
7(a) Small | $350,000 | 10 years; 25 for real estate | Smaller term loans |
SBA Express | $500,000 | Lines up to 10 years | Lender-led decisions |
504 | $5 million; $5.5 million for some projects | 10, 20 or 25 years, fixed | Buildings, long-life machinery |
Microloan | $50,000 | 7 years | Start-up and small working capital |
CAPLines | $5 million | 10 years (Builders shorter) | Seasonal, contract or receivables cash |
Limits come from SBA's program pages, its lender terms page and its rulebook, SOP 50 10 8.1. The 504 regulation, 13 CFR 120.931, reserves the $5.5 million ceiling for small manufacturers and certain energy projects.
Reality check: the most streamlined program protects the lender least. Under SBA Express the lender mainly uses its own forms and makes the credit decision. SBA guarantees 50%, against 85% for a 7(a) Small loan of $150,000 or less. A lender carrying half of any loss has little reason to stretch. Express suits a borrower already close to bankable. One who is not may find a 7(a) Small loan the likelier yes.
Speed is worth having only when approval is already likely.
What Must Your Business Plan Prove for Each SBA Program?
Each program asks the plan a different question. A 504 loan asks for the project and the jobs it creates. CAPLines ask for the cash cycle in numbers. A microloan asks for prospects at small scale. A generic plan answers none of them, so write toward the program before you write the plan.
For a 504 loan, the project and the jobs. Under SOP 50 10 8.1, a project must create or retain one job opportunity per $95,000 guaranteed by SBA. The ratio is $150,000 for small manufacturers and energy projects. Jobs count if created within two years of receiving the funds. A project may qualify instead on a public-policy goal, such as cutting energy use by at least 10%. The application "must indicate how the Project will meet the specified economic development objective." The plan needs a headcount for today and for two years out.
For CAPLines, the cycle in numbers. A Seasonal CAPLine requires 12 months of operation and "a definite pattern of seasonal activity." Its amount rests on cash flow projections of the buildup. One permitted sizing for a Working Capital CAPLine is: Working Capital CAPLine = (Prior-year net sales / 365) x Days in the sales cycle A business with $730,000 in prior-year sales and a 60-day cycle gets $2,000 a day times 60, or $120,000. A Contract CAPLine paid in installments is sized at 20% above the greatest projected cash deficit. Each method reads from a monthly cash forecast.
For a microloan, prospects at small scale. Under 13 CFR 120.707, intermediaries should generally lend no more than $10,000. Above $20,000 the borrower must show it cannot get comparable credit elsewhere and "has good prospects for success." SBA does not review microloans for creditworthiness. The intermediary, a nonprofit lender that also provides technical assistance, decides.
A generic plan answers none of these questions. Our SBA loan business plan guide covers the parts every program reads.
Can You Combine SBA Loan Programs?
Yes. Many businesses carry two financing problems at once, such as a building to buy and stock to fund. The programs can run side by side: a 504 loan on the premises and a revolving line for the cycle. The risk is stretching one loan to cover both and crossing a threshold without noticing.
Under the SOP, a 7(a) Small loan may only be increased up to $350,000. Above that, "it becomes a Standard 7(a) loan." A request near the line should be sized deliberately, not rounded up.
Reality check: the programs built for assets and cycles will not fund the trough. The 504 program excludes working capital. Seasonal CAPLine funds must not be used to "Maintain activity during the slow periods of the business's cycle." Microloans cannot repay existing debt. The quiet months are paid for by margin saved in the peak or by a term loan repaid from the same seasonal cash. The plan must show which.
What Does an SBA Loan Really Cost?
The cost of an SBA loan depends on four levers. Is the rate fixed or variable? Does the term match the asset? Might you prepay early? And how do collateral rules shift with size? Each one changes the total cost more than the headline rate does.
Fixed against variable. 504 rates are fixed and pegged above the 10-year Treasury rate. 7(a) rates may be fixed or variable, per SBA's lender terms page. Variable caps run from base rate plus 6.5% on loans of $50,000 or less to base rate plus 3.0% above $350,000. Microloans generally cost 8% to 13%.
Match the term to the asset. A 7(a) term runs ten years or less unless it finances real estate or longer-lived equipment, up to 25 years. A short need on a long term wastes interest. A building on a short term squeezes cash.
Long terms carry exit costs. On 7(a) loans of 15 years or more, prepaying 25% or more of the balance in the first three years carries a penalty. It is 5% of the amount prepaid in year one, 3% in year two and 1% in year three. Prepay $200,000, half the balance of a 20-year loan, in year one and the penalty is $10,000. A plan for an early sale should price that in.
Collateral rules shift with size. SBA requires no collateral on 7(a) Small loans of $50,000 or less. Above that, "a loan is not to be declined solely on the basis of inadequate collateral." Cash flow, not collateral, is the primary source of repayment, the SOP says.
Conclusion: Match the Program, Then Write the Plan
Choosing among SBA loans for small businesses is a matching exercise. Long-life assets point to 504, cycling cash to CAPLines or a working capital line, mixed needs to 7(a), and small first steps to a microloan.
Owners who settle the program first write a sharper plan: jobs for 504, the cycle for CAPLines, prospects for a microloan. A plan built around the right question, with a monthly cash forecast behind it, is ready for whichever lender holds the right door. SBA loans are one route to funding a small business. Grants and other funding alternatives sit alongside them, and each reads the same forecast.
