The interest rate on your business loan is just one piece of the total cost equation. Hidden fees, origination charges, prepayment penalties, and the structure of how interest accrues can make loans with similar stated rates look very different when you calculate their true cost. Understanding exactly what you are paying — and why — is essential for making smart financing decisions and negotiating better terms. This guide breaks down every major component of business loan pricing, explains how to compare loans accurately, and shows you what to watch for in the fine print.
In This ArticleBusiness loan interest rates determine what you pay the lender in exchange for borrowing money. Interest is typically expressed as an annual percentage — hence Annual Percentage Rate (APR) — but it accrues based on your outstanding balance according to your loan's amortization schedule.
Most business term loans use simple interest, meaning interest is calculated on the outstanding principal balance each period. As you make payments and reduce the principal, the interest charged each month decreases. This amortization effect means early payments contain more interest and later payments contain more principal.
Some short-term lending products and lines of credit use daily compounding, where interest accrues daily on the current balance. For short loan terms, the difference between simple and compound interest is minimal. For longer terms or revolving products, understanding whether your rate is simple or compounding matters for accurate cost calculation.
On a fully amortized loan, every payment is the same amount but the composition shifts over time. A 5-year $200,000 loan at 12 percent APR has monthly payments of approximately $4,445. In month 1, roughly $2,000 of that payment is interest and $2,445 is principal. By month 60, only about $44 is interest and $4,401 is principal. Total interest paid over 5 years at 12 percent on $200,000 is approximately $66,700.
Lenders set your interest rate by starting from a benchmark rate (like the Federal Funds Rate or Prime Rate) and adding a risk premium based on your specific profile. Factors that increase your risk premium — and therefore your rate — include lower credit score, shorter time in business, weaker cash flow, higher debt-to-income ratio, and operating in a higher-risk industry. Factors that reduce your rate include strong credit, established business history, substantial collateral, and consistent revenue growth.
A fixed rate stays the same for the entire loan term regardless of what happens to market interest rates. Fixed rates provide payment certainty and make budgeting straightforward. The tradeoff is that you cannot benefit if market rates fall, and you typically pay a small premium over variable rates at the time of origination because the lender is bearing the rate risk.
Fixed rates are generally preferable when you believe interest rates are likely to rise, when you need payment predictability for budgeting, or when you are taking a long-term loan where rate volatility over many years is difficult to manage.
Variable rates are tied to a benchmark rate (typically the Prime Rate or SOFR) and adjust periodically — monthly, quarterly, or annually. When benchmark rates fall, your rate and payment fall. When they rise, your payment increases. Variable rates are typically lower than fixed rates at origination because the borrower bears the rate risk.
Variable rates may be preferable for short-term loans where rate moves during the term are unlikely to be dramatic, when you expect rates to fall, or when the initial rate savings are significant enough to justify the uncertainty.
SBA 7(a) loans use variable rates tied to the Prime Rate with the SBA setting maximum spreads: Prime + 2.25% for loans over 7 years, Prime + 2.75% for shorter terms (for loans over $50,000). The current Prime Rate as of early 2026 is approximately 7.5%, placing typical SBA rates in the 9.75% to 12% range. These rates reset quarterly with Prime Rate changes.
Here is a summary of current rate ranges across major business loan products as of 2026. Actual rates depend heavily on your specific financial profile:
| Loan Type | Typical APR Range | Credit Required |
|---|---|---|
| SBA 7(a) Loan | 9.75% – 12.25% | 680+ |
| SBA 504 Loan | 6.5% – 9.5% (fixed) | 680+ |
| Bank Term Loan | 7% – 18% | 660–680+ |
| Business Line of Credit | 10% – 30% | 620–650+ |
| Alt. Lender Term Loan | 18% – 45% | 550+ |
| Equipment Financing | 6% – 25% | 550+ |
| Revenue-Based Financing | 25% – 60% | 550+ |
| Invoice Financing | 12% – 36% (annualized fee) | Flexible |
| Merchant Cash Advance | 60% – 200%+ (effective APR) | 500+ |
These are market ranges as of early 2026 and will change as the Federal Reserve adjusts the federal funds rate. Your actual rate depends on your personal credit score, business credit profile, annual revenue, time in business, collateral, and the specific lender's underwriting standards.
The interest rate and the APR are not the same number, and confusing them leads to poor loan comparisons.
The interest rate is the cost of borrowing expressed as an annual percentage of the loan principal. It does not include fees. Two loans with the same interest rate but different fees have different true costs.
APR includes both the interest rate and most fees (origination fee, closing costs, broker fees) expressed as an annual percentage. APR is a more complete measure of borrowing cost and is the right number to compare across loan offers.
Loan A: $100,000, 12% interest rate, $3,000 origination fee, 3-year term → APR ≈ 14.2%
Loan B: $100,000, 13% interest rate, no origination fee, 3-year term → APR ≈ 13%
Despite Loan A's lower stated rate, Loan B costs less in total due to no origination fee.
Unlike loans that use APR, merchant cash advances and some short-term products use factor rates — a decimal multiplier that determines the total repayment amount regardless of time. A factor rate of 1.3 means you repay $1.30 for every $1.00 borrowed.
Factor rates cannot be directly compared to APRs without converting them. The key formula is:
This illustrates why the effective APR on an MCA depends heavily on how quickly it is repaid — faster repayment means higher effective cost per year.
Beyond the interest rate, business loans come with a variety of fees that significantly affect total cost. Here are the most common:
Charged by most lenders as a percentage of the loan amount (typically 1 to 5 percent), the origination fee covers the cost of processing and underwriting the loan. Some lenders deduct it from the loan proceeds (you receive less than the stated amount) while others add it to the loan balance. Either way, it adds to your total cost. A 3 percent origination fee on a $100,000 loan is $3,000.
Common in SBA loans and commercial real estate financing, closing costs include legal fees, title insurance, recording fees, and appraisal fees. Closing costs on SBA loans typically run 2 to 4 percent of the loan amount. For a $500,000 SBA loan, expect $10,000 to $20,000 in closing costs.
The SBA charges a guarantee fee on 7(a) loans to fund the loan guarantee program. For loans over $150,000, the fee is 3.0 percent of the guaranteed portion for loans up to 12 months, and 3.5 percent for longer-term loans. The fee can be financed into the loan amount. This adds approximately $3,500 per $100,000 of SBA-guaranteed loan amount.
Many loans charge a fee for paying off the loan early. SBA loans have graduated prepayment penalties: 5 percent in year 1, 3 percent in year 2, and 1 percent in year 3 (for loans with terms over 15 years). Some commercial bank loans have flat penalties of 1 to 3 percent. Always check the prepayment terms before signing — they become important if you plan to refinance.
Business lines of credit often charge annual maintenance fees ($100 to $500) to keep the facility open, even if you do not draw on it. Some lenders also charge a monthly maintenance fee ($25 to $100). These fees must be factored into your cost calculation for lines of credit.
Some lines of credit charge a draw fee (typically 1 to 3 percent of the amount drawn) each time you access the credit line. This can significantly increase the effective cost of a line of credit for businesses that make frequent small draws.
Missing a payment typically triggers a late fee (often $25 to $50 or 5 percent of the payment amount, whichever is greater) and may also trigger a penalty interest rate increase. Late payments also damage your business credit score, which affects future borrowing costs.
Some business lines of credit charge a fee on the undrawn portion of the facility — essentially a carrying cost for having the line available. This fee is common in larger commercial credit facilities. If your line has a non-utilization fee, factor that into your cost whether you draw on it or not.
The most accurate way to compare two loan offers is to calculate the total cost of each over the full loan term:
Comparing total cost rather than monthly payment gives you a complete picture of what each option truly costs over its lifetime.

Interest rates and fees are not always fixed — there is often room to negotiate, particularly with conventional lenders and SBA programs. Here is how to improve your rate:
Every 20 to 40 point improvement in your personal credit score can meaningfully lower your rate. Pay down revolving balances, remove reporting errors, and allow time for your score to reflect recent positive payment activity before applying.
Secured loans have lower rates than unsecured loans because collateral reduces the lender's risk. Offering real estate, equipment, or other business assets as collateral — even when not required — can improve your offered rate.
A larger equity contribution reduces the loan-to-value ratio, which reduces lender risk and can lower your rate. For SBA loans, coming in with 20 to 30 percent down (when the minimum is 10 percent) can improve terms.
Lenders price risk differently. The same financial profile may receive a 15 percent rate from one lender and a 22 percent rate from another. Applying to multiple lenders and using competing offers as negotiating leverage consistently produces better outcomes than accepting the first offer. Crestmont Capital's network allows you to compare multiple products with a single application.
Origination fees, annual fees, and draw fees are often negotiable, especially for strong borrowers or existing banking relationships. Simply asking "Can you waive or reduce the origination fee?" results in savings more often than most borrowers expect.
