When you look at a small business loan offer, the price tag feels mysterious. Why does one lender charge 8% interest while another charges 15%? The answer lies in how lenders think about risk and what it costs them to do business.

Small businesses represent genuine risk to lenders. Unlike large corporations with decades of financial history and established credit markets, a small business might be three years old or three months old. The lender doesn't know if the owner will succeed or fail. They're essentially betting money on an uncertain future. To protect themselves from potential losses, lenders charge higher interest rates to small businesses than to large corporations, which can borrow at rates around 5-6%. A typical small business loan runs between 7% and 30%, depending on dozens of factors.
The cost of originating a loan—the paperwork, the underwriting, the compliance work—gets built into what you pay. Lenders must verify your identity, pull credit reports, review tax returns and bank statements, and assess your business plan. For a $50,000 loan, these steps might cost the lender $1,000 to $3,000 in labor and systems. That cost gets recouped through your interest payments and any upfront fees.
Your personal credit score significantly influences the rate you'll see. Someone with a credit score of 750 might receive a 9% rate on a $100,000 term loan, while someone with a score of 650 might see 16% for the same loan amount. Credit scores reflect your history of repaying debts. Lenders use this as a proxy for whether you'll repay the business loan.
The type of collateral you can offer also drives costs down. If you pledge business equipment, real estate, or personal assets as collateral, you're offering the lender a safety net. They can seize and sell that collateral if you default. Unsecured loans—those without collateral—carry much higher rates because the lender has no recovery option besides pursuing legal action.
Takeaway: Small business loan rates reflect three main things: risk (based on your credit and business history), lender operating costs, and collateral availability. Understanding this framework helps you see why your rate looks the way it does and where you might negotiate or improve your position.
Small businesses don't borrow money in just one way. Different loan structures serve different purposes, and each comes with different costs. Learning the differences between types helps you compare apples to apples when reviewing offers.

A term loan is the most straightforward option. You receive a lump sum of money upfront, and you repay it over a fixed period—typically 2 to 10 years—with a fixed or variable interest rate. If you borrow $100,000 at 10% interest over five years, you'll make 60 equal monthly payments of approximately $2,125. The predictability makes budgeting easier. Term loans work well for equipment purchases, expansion projects, or working capital needs. Banks, credit unions, and online lenders all offer term loans.
Lines of credit function differently. Instead of receiving one lump sum, you receive access to a pool of money. You can draw from it as needed, repay what you've drawn, and draw again—similar to a credit card. You only pay interest on the amount you actually use. A $50,000 line of credit might cost you nothing per month if you don't use it, but if you draw $30,000, you'll pay interest only on that $30,000. Interest rates on lines of credit often run 1-3 percentage points higher than term loans because of this flexibility. Many small businesses use lines of credit for seasonal fluctuations or unexpected expenses.
SBA loans are programs created by the U.S. Small Business Administration where the government backs a portion of the loan—typically 75-90%. This backing reduces the lender's risk, which translates to lower interest rates for you. SBA 7(a) loans, the most common type, typically charge interest rates 2-3 percentage points below market rates for unsecured term loans. The trade-off: SBA loans involve more paperwork and take 4-8 weeks to process. The SBA also charges guarantee fees (typically 2-3% of the loan amount) that you must pay.
Equipment financing ties the loan directly to the equipment you're purchasing. The equipment itself serves as collateral. This reduces the lender's risk, so rates run lower—often 6-12%. If you default, the lender repossesses the equipment. This option works when you need specific machinery, vehicles, or technology.
Invoice factoring and merchant cash advances operate on different economics entirely. With invoice factoring, a company buys your outstanding invoices at a discount—perhaps paying you 80 cents for every dollar owed—and collects the full amount from your customers. You get cash immediately but lose revenue. Merchant cash advances work with credit card processors; the lender provides upfront cash and takes a percentage of your daily credit card sales until they've recouped their investment plus their profit. These options are expensive—effectively 30-100% annual rates—but require minimal underwriting and reach businesses with poor credit.
Takeaway: Match the loan type to your actual need. Buying equipment? Equipment financing saves you money. Unpredictable cash flow? A line of credit offers flexibility. Building credit or needing speed? A merchant cash advance might make sense despite the cost. Comparing across loan types is comparing different products, not just different prices.
Interest rates get all the attention, but they tell only part of the story about what you'll actually pay. A loan advertising a "9% rate" might end up costing you significantly more when you factor in fees, origination charges, and prepayment penalties.

Origination fees are the most common add-on cost. These are charged by the lender to process your loan application and set up the loan account. Origination fees typically range from 1% to 5% of the loan amount. On a $50,000 loan with a 3% origination fee, you'd pay $1,500 upfront. Some lenders deduct this fee from your loan proceeds, meaning you receive $48,500 and owe back the full $50,000—effectively increasing your interest rate.
SBA loans include guarantee fees. When you use an SBA 7(a) loan, you pay the SBA a guarantee fee (2-3% of the loan amount) and potentially a servicing fee (0.55% annually) to cover the government's costs of guaranteeing the loan. These aren't optional if you want the SBA's backing and lower rates.
Prepayment penalties can trap you. Some lenders charge you a fee if you repay the loan early—sometimes a percentage of the remaining balance or a flat amount. If you refinance with better terms a year later, prepayment penalties can cost you $2,000-$10,000 or more. Always ask: "Is there a prepayment penalty, and if so, what is it?"
Annual maintenance fees, administrative fees, and account fees add up quietly. Some lenders charge $25-$100 per year just to keep the account open. Credit unions and traditional banks tend to charge fewer ancillary fees than online lenders.
For lines of credit, watch for annual fees and unused fees. You might pay $100-$300 per year just to have the line open, regardless of whether you use it. Some lenders also charge fees if you don't draw a minimum amount.
Insurance requirements can be a hidden cost. Some SBA lenders require you to carry life insurance on yourself as the business owner, naming the lender as beneficiary. Term life insurance for a 40-year-old in good health might cost $50-$150 per year for the coverage needed, but lenders sometimes require specific policies they approve.
To calculate true cost, use the Annual Percentage Rate (APR). APR incorporates the interest rate plus fees, expressed as an annualized percentage. A loan showing a 9% interest rate but with a 3% origination fee might have an APR of 10.2%. Lenders are required to disclose APR in the United States, so always ask for it and compare APR across lenders, not just stated interest rates.
