Types of Business Loans

Choosing the right type of business loan can save tens of thousands of dollars in interest and fees, and can mean the difference between getting funded and being declined. The three most common types of small business financing — term loans, SBA 7(a) loans, and lines of credit — each serve different purposes and come with distinct characteristics, requirements, and costs.

Term loans are the most straightforward: you borrow a fixed amount, make regular payments over a set period, and the loan is fully paid off at the end. Term loans from banks typically offer the lowest interest rates (prime + 1–3%) but require strong credit, established business history, and collateral. Online lenders offer faster funding with lower requirements but at higher rates. Term loans work best for specific, one-time capital needs: equipment purchases, expansion, acquisition, or refinancing existing debt.

SBA 7(a) loans are government-backed loans that allow lenders to provide financing to businesses that wouldn't otherwise qualify for conventional loans. The SBA guarantees up to 85% of loans under $150,000 and 75% of larger loans. This guarantee reduces lender risk, enabling longer terms (up to 10 years for working capital, 25 years for real estate) and lower rates than conventional small business loans. The trade-off is documentation — SBA loans require extensive paperwork and typically take 30–90 days to close.

Lines of credit work like a credit card for your business: you have a credit limit, borrow what you need, repay it, and borrow again. Interest is paid only on the outstanding balance. Lines of credit are ideal for managing cash flow gaps, seasonal inventory needs, and unexpected expenses. They come in secured (backed by collateral) and unsecured forms. Revolving lines of credit remain available after repayment; non-revolving lines close once fully repaid.

SBA 7(a) Loan Details

The SBA 7(a) program is the SBA's flagship lending program and the most popular small business loan in the United States. In fiscal year 2023, the SBA approved over 57,000 7(a) loans totaling more than $27 billion. Understanding how SBA loans work helps you evaluate whether one is right for your business.

Maximum loan amount: $5 million. There's no minimum, though most lenders have practical minimums of $50,000–$100,000.

Interest rates: SBA loans have maximum rates tied to the prime rate. For loans over $50,000 with terms over 7 years: prime + 2.75% max. For loans under $50,000: prime + 6.5% max. As of 2024, with prime at 8.5%, rates typically range from 10.5% to 15%.

Terms: Up to 10 years for equipment and working capital; up to 25 years for commercial real estate.

SBA guarantee fee: The SBA charges a guarantee fee paid to the SBA by the lender, which is typically passed to the borrower. For 2024: loans of $150,000 or less pay no guarantee fee; loans from $150,001 to $700,000 pay 3% of the guaranteed portion (75%); loans from $700,001 to $5 million pay 3.5% on the first $1 million guaranteed and 3.75% above that. SBA periodically waives fees for certain borrowers — check current SBA guidance.

Use of funds: 7(a) loans can be used for almost any legitimate business purpose: working capital, equipment, real estate, refinancing, inventory, and business acquisition. This versatility is one of the program's biggest advantages over more restrictive loan types.

SBA 504 Loans: The Alternative for Fixed Assets

While 7(a) loans are flexible, the SBA 504 program is specifically designed for major fixed asset purchases: commercial real estate, heavy equipment, and machinery. 504 loans are structured as two loans: typically 50% from a conventional bank, 40% from a Certified Development Company (CDC) backed by SBA, and 10% from the borrower as down payment.

The 504 structure often produces below-market rates on the CDC portion, which is funded by SBA-guaranteed debentures sold to investors. For qualified borrowers purchasing commercial real estate, 504 loans frequently offer lower total costs than 7(a) loans. However, they have more restrictions on use of funds (primarily for fixed assets) and a more complex closing process.

If you're buying a building for your business, comparing 7(a) and 504 side by side is worth the effort. A financial advisor or SBA lender can model both options for your specific transaction.

Debt Service Coverage Ratio (DSCR)

Lenders evaluate business loan applications primarily based on Debt Service Coverage Ratio (DSCR) — the ratio of your business's annual net operating income to its annual debt service (principal + interest payments). A DSCR of 1.0 means your business exactly covers its debt payments; below 1.0 means you can't cover payments from business income; above 1.0 means you have a cushion.

Most lenders require a minimum DSCR of 1.25, meaning your business generates 25% more income than needed to cover debt payments. SBA lenders typically require 1.15–1.25 minimum DSCR. Stronger DSCR (1.5+) results in better loan terms. Lenders calculate DSCR using your most recent 2–3 years of tax returns or financial statements.

Formula: DSCR = Net Operating Income ÷ Annual Debt Service. If your business generates $150,000 in net operating income and your proposed loan payments would be $100,000/year, your DSCR is 1.50 — strong enough to qualify with most lenders.

Personal Guarantees

Almost all small business loans — including SBA loans — require personal guarantees from owners with 20% or more ownership. A personal guarantee means that if the business defaults, the lender can pursue the owner's personal assets: home equity, savings, vehicles, and investment accounts.

SBA loans require an unlimited personal guarantee from all owners with 20%+ ownership. Some conventional lenders offer limited personal guarantees — capping liability at a specific dollar amount — but these are rare for small business loans. Larger businesses with strong financial profiles and significant collateral may negotiate reduced or limited guarantees.

Understanding the personal guarantee implications before signing is critical. Many business owners don't fully appreciate that a failed business loan can result in personal bankruptcy. Strong business insurance, LLC structure, and conservative borrowing help manage this risk, but they don't eliminate it.

Credit Requirements for Business Loans

Lenders evaluate both your personal credit and your business credit when underwriting a business loan. Requirements vary by lender type:

• Traditional banks: Typically require 680+ personal FICO, 2+ years in business, $250,000+ annual revenue
• SBA 7(a) through bank: Usually 680+ FICO, 2+ years, positive cash flow; SBA allows lenders some flexibility
• Online lenders: May approve 600+ FICO with 1 year in business, but at significantly higher rates
• Microloans (under $50,000): May approve startups and lower credit scores; focus on cash flow and business plan

Business credit scores (Dun & Bradstreet PAYDEX, Experian Business, Equifax Business) are separate from personal credit. Building a strong business credit profile — registering with D&B, opening trade accounts, paying vendors on time — improves access to credit and loan terms over time.

Alternative Lenders and Fintech Business Loans

Online and fintech lenders have democratized access to business financing for companies that don't qualify for traditional bank loans. Major platforms include OnDeck, Kabbage, Fundera, BlueVine, Lendio, and Credibly. These lenders typically approve faster (sometimes same-day) and with less documentation, but at significantly higher interest rates — often 20–40% APR or more.

Revenue-based financing is another alternative: the lender provides capital in exchange for a percentage of future revenue until the advance plus fees is repaid. This structure suits seasonal businesses or companies with inconsistent cash flow but strong revenue. Merchant cash advances (MCAs) are similar but tied to credit card sales — and are notoriously expensive, with effective APRs often exceeding 50%.

If you're considering alternative financing, always convert quoted rates to APR for an apples-to-apples comparison. A "factor rate" of 1.3 over 6 months sounds manageable, but the effective APR is often 50–80%.

How to Apply for an SBA Loan

Step 1: Prepare your documents. SBA loan applications typically require: 3 years of business tax returns, 3 years of personal tax returns, current financial statements, business plan (for newer businesses), a list of existing debts, and information on collateral being offered.

Step 2: Find an SBA-approved lender. Use the SBA's lender match tool at sba.gov, or contact local SBA district offices for referrals to preferred lenders (PLPs) who have streamlined approval authority.

Step 3: Complete the application. SBA applications include SBA Form 1919 (borrower information) and Form 912 (statement of personal history), plus lender-specific forms.

Step 4: Wait for approval. SBA Express loans can be approved in 36 hours. Standard SBA 7(a) loans take 30–90 days from application to funding. Having complete documentation speeds the process significantly.

Frequently Asked Questions

What credit score do I need for a business loan?

For traditional bank loans and SBA loans, most lenders require a personal credit score of 680 or higher. Some SBA lenders will work with scores in the 650–679 range with compensating factors (strong revenue, collateral, time in business). Online and alternative lenders may approve scores as low as 600, but at higher interest rates. Building your personal credit score before applying can significantly improve your terms — even a 20-point improvement can move you from one rate tier to a better one.

What is the SBA guarantee fee?

The SBA guarantee fee is a one-time fee charged on the guaranteed portion of an SBA 7(a) loan. For 2024: no fee on loans of $150,000 or less; 3% of the guaranteed portion (75% of loan) for loans from $150,001 to $700,000; 3.5% of the first $1 million guaranteed plus 3.75% above that for larger loans. The fee is typically rolled into the loan, so you don't need cash upfront. The SBA periodically waives fees for certain underserved communities or during economic stimulus periods — check the current SBA website for the latest fee schedule.

How long does SBA loan approval take?

SBA Express loans (under $500,000 with expedited review) typically receive a decision within 36 hours, though full funding takes 30–60 days. Standard SBA 7(a) loans take 60–90 days from application submission to funding. Preferred Lender Program (PLP) lenders have delegated approval authority and can process loans faster than standard lenders. The timeline depends heavily on how quickly you provide complete documentation — incomplete applications are the most common cause of delays. Working with an experienced SBA lender who specializes in your loan type can reduce approval time significantly.
