As the name suggests, business loans are financing tools meant for commercial activities. Like other credit products, they oblige borrowers to repay the principal together with interest. Most of these loans are structured with monthly installments, though some may be arranged weekly, daily, or as interest‑only schedules, and a few are due in full at maturity.

Business financing is available in numerous formats. Below is a rundown of the typical loan types offered to U.S. enterprises.

SBA Loans

Loans backed by the U.S. Small Business Administration (SBA) are government‑guaranteed programs that cater to a wide range of business financing needs. Depending on the specific SBA program, borrowers may use the proceeds for several purposes, such as:

• Business start-ups
• Acquisitions
• Working capital
• Real estate
• Franchise financing
• Debt refinancing
• Improvements
• Renovations

Although SBA loans are guaranteed by the agency, the actual cash comes from banks, community lenders, or other financial institutions. The SBA backs 75‑90 % of the loan amount for the lender, lowering their risk. This guarantee makes lending easier but comes with extra paperwork, additional fees, longer approval times, stricter covenants, and often lower loan ceilings that may not satisfy larger projects.

SBA Loan Types

The SBA offers four types of small business loans:

7(a) Loan

This is the primary small business loan offered by the SBA, and it is usually what one means when referring to an "SBA loan."

The 7(a) program accounts for over three‑quarters of all SBA lending, supporting a variety of needs—from working capital to equipment, land, or building purchases. Borrowers may also refinance debt with these loans. Funding can reach up to $5 million for a 10‑year term for working capital or up to 25 years for fixed‑asset financing.

Microloan

Micro‑loans target start‑ups and expanding small businesses. They can be used for any purpose allowed under the 7(a) program except for paying off existing obligations or buying real estate. Lenders may approve amounts as high as $50,000, though the typical loan is around $15,000, with a maximum term of six years.

Real Estate & Equipment Loan (CDC/504)

CDC/504 loans are designed for long‑term, fixed‑rate financing of real estate or equipment and for refinancing debt. Because they are earmarked for these specific assets, they cannot be used for working capital or inventory. The program caps loans at $5.5 million, available in 10‑, 20‑, or 25‑year terms.

Disaster Loan

In the event of a declared disaster, owners can draw on these loans to repair or replace damaged machinery, property, equipment, inventory, or other business assets. The maximum financing limit is $2 million, and eligible catastrophes include earthquakes, storms, floods, fires—whether natural or man‑made—and civil unrest.

Other Loan Types

Conventional Loans

Conventional business loans are typically originated by banks or other lenders and do not carry a federal guarantee like SBA loans. Consequently, they often feature higher interest rates and shorter repayment periods. Borrowers with weaker credit or limited financing options may find SBA loans more appealing, while borrowers with strong credit may obtain personal loans at lower rates, benefiting from a faster, less regulated approval process.

Banks offer conventional loans in many different forms, such as mezzanine financing, asset-based financing, invoice financing, business cash advances, and cash flow loans.

Personal Loans

Sometimes entrepreneurs turn to personal loans to fund a fledgling business, especially when they lack a track record that would qualify them for a traditional business loan. These loans can help dodge the steep rates that many business‑specific products carry. See the Personal Loan Calculator for details or to run your own numbers.

Interest-Only

An interest‑only loan works differently from a regular loan: the borrower pays just the accrued interest for the life of the loan, while the full principal stays untouched until the final due date. This structure can lower monthly outlays now, which may be attractive if the borrower expects a sizable income boost later on.

Business Loan Fees

Beyond the base interest, most business credit products carry additional charges. Lenders usually impose fees to cover tasks like verifying applicant data, preparing documentation, and other administrative work. The most frequent of these are the origination fee and the documentation fee.

Origination Fee

The origination fee compensates the lender for reviewing and approving the loan request, which often involves checking the borrower's credit and financial background. This charge can be a flat amount or a percentage of the loan—typically between one and six percent—and is frequently added to the total loan balance.

Documentation Fee

This is a common fee associated with loans that banks charge to cover the cost of processing paperwork.

Besides the origination fee and documentation fee, some lenders may also charge an application fee upfront to review the application.

During the life of a loan, banks may also levy a variety of other charges, such as:

• Monthly administrative fees
• Annual fees
• Service or processing fees
• Prepayment penalties
• Referral fees
• Late payment fees
• Wire transfer fees

Not every creditor applies all of these fees. Some, like late‑payment penalties or pre‑payment charges, only come into play under specific circumstances.

The Bottom Line

All of these additional costs can push the true expense of a loan above the headline interest rate. Our calculator factors in these fees, giving borrowers a clearer picture of the loan’s overall cost.
