Business Loan Calculator
A business loan calculator helps you estimate monthly payments, total interest, and overall repayment costs before committing to any financing. Whether you are applying for an SBA loan or a commercial term loan, simply enter your loan amount, interest rate, and term. You get an instant payment breakdown showing exactly what you owe each month. Understanding the full cost of borrowing helps business owners compare lenders and choose the loan structure that best fits their cash flow.
How Business Loan Payments Are Calculated
Most business loans use standard amortization, which spreads principal and interest into equal monthly payments over the loan term. The formula is:
Monthly Payment = P × [r(1+r)^n] ÷ [(1+r)^n − 1]
Where P is the loan principal. The variable r is the monthly interest rate (annual rate divided by 12), and n is the total number of monthly payments.
Example: A $100,000 business loan at 7% annual interest over 5 years (60 months) gives a monthly interest rate of 0.5833%. Monthly payment = $1,980. Total paid over 5 years = $118,800. Total interest cost = $18,800.

Types of Business Loans
Different loan types have different structures, terms, and qualification requirements. Choosing the right type affects both your monthly payment and your total borrowing cost.
SBA Loans
The U.S. Small Business Administration (SBA) guarantees a portion of loans made by approved lenders, reducing lender risk and allowing lower interest rates for qualifying borrowers. SBA loans are among the most affordable business financing options available for small businesses.
- SBA 7(a) Loan: According to the U.S. Small Business Administration (SBA), the 7(a) program lends up to $5M. Terms run up to 10 years for working capital and 25 years for real estate. Interest rates typically 10.5%–13%. The SBA guarantees 75%–90% of the loan amount, making approval more accessible for businesses that cannot qualify for conventional financing.
- SBA 504 Loan: The SBA 504 program provides up to $5.5M specifically for major fixed assets such as commercial property or heavy equipment. Combines a bank loan (50%), a Certified Development Company (CDC) contribution (40%), and a borrower down payment of 10%. This structure results in below-market interest rates.
- SBA Microloan: Up to $50,000 for startups and small businesses needing limited capital. The average SBA Microloan size is $13,000. Terms up to 6 years, with interest rates typically 8%–13%. Funds come through nonprofit intermediary lenders who also provide business counseling.
- SBA Express Loan: Up to $500,000 with an approval decision within 36 hours. Higher rates (11%–14%) in exchange for faster processing. Useful for urgent working capital needs.
Conventional Term Loans
Offered directly by banks and credit unions without SBA backing. Terms range from 1 to 10 years. Interest rates depend on business credit score, revenue history, and collateral. A business with strong financials and a credit score above 700 may secure rates of 5%–8% from traditional lenders. Loan amounts range from $10,000 to $5M depending on the institution.
Equipment Loans
Designed specifically for purchasing business equipment — machinery, vehicles, manufacturing tools, or technology. The equipment itself serves as collateral, which often makes qualification easier than unsecured financing. Loan terms typically match the expected useful life of the equipment, usually 3–7 years. Average rates range from 4%–20% depending on lender and borrower creditworthiness.
Business Lines of Credit
A line of credit lets you draw funds as needed up to a set limit. You repay on a revolving basis, similar to a business credit card. Lines of credit are best for managing cash flow gaps or covering irregular expenses. They typically carry higher interest rates than term loans (8%–24%) and may include annual maintenance fees.
Commercial Real Estate Loans
Used to purchase, develop, or refinance commercial property. Terms range from 5 to 25 years, often with a balloon payment at the end of the term. Interest rates are typically 5%–9% for well-qualified borrowers. Loan-to-value (LTV) ratios are usually capped at 75%–80%, meaning a $500,000 property may require a $100,000–$125,000 down payment.
Secured vs Unsecured Business Loans
Understanding the difference between secured and unsecured business loans is critical for choosing the right product and negotiating better terms.
Secured loans require collateral — real estate, equipment, inventory, or accounts receivable — that the lender can claim if you default. Because the lender's risk is lower, secured loans offer lower interest rates and larger loan amounts. SBA loans, commercial mortgages, and equipment loans are all secured.
Unsecured loans require no collateral but depend entirely on the borrower's creditworthiness and financial history. They carry higher interest rates (typically 8%–30%) and lower loan limits. Business credit cards, short-term working capital loans, and merchant cash advances are common unsecured products.
For most small businesses, secured loans are the lower-cost option when assets are available to pledge as collateral.
What Affects Your Business Loan Interest Rate?
Interest rates for business loans vary widely — from 4% at credit unions to 30%+ for short-term online lenders. These factors determine where your rate falls:
- Business credit score: Scores above 80 on the Dun & Bradstreet PAYDEX scale or personal FICO scores above 700 typically unlock the best rates. Scores below 600 may result in loan denial or rates above 20%.
- Time in business: Most traditional lenders require at least 2 years of operating history. Startups face higher rates or must use SBA Microloan programs or alternative lenders.
- Annual revenue: Traditional lenders typically require $100,000–$250,000 in annual revenue. Higher and more consistent revenue reduces perceived risk and lowers your rate.
- Collateral: Loans backed by real estate, equipment, or inventory carry lower rates than unsecured products. The quality and liquidity of collateral affects the rate offered.
- Loan term: Shorter terms generally carry lower interest rates. A 2-year loan costs less per dollar borrowed than a 10-year loan at the same lender.
- Economic conditions: Business loan rates are influenced by the Federal Reserve's benchmark interest rate. When the Fed raises rates, business loan rates typically rise within 30–90 days.
Business Loan Fees to Factor In
The stated interest rate is only part of the true borrowing cost. Fees can significantly increase what you actually pay. Always review these charges before signing any loan agreement:
- Origination fee: Charged upfront, typically 1%–6% of the loan amount. A $100,000 loan with a 3% origination fee adds $3,000 to your cost before the first payment. This fee is often rolled into the loan balance.
- Documentation fee: Covers the cost of processing paperwork and legal review. Usually $150–$500 for standard business loans, higher for complex commercial deals.
- Prepayment penalty: Some lenders charge a fee if you repay the loan ahead of schedule. SBA 7(a) loans with terms over 15 years carry prepayment penalties if repaid within the first 3 years. Typical penalty: 5% in year one, 3% in year two, 1% in year three.
- Annual fee: Common on lines of credit — typically $75–$250/year to keep the account open, regardless of usage.
- Late payment fee: Usually 3%–5% of the overdue payment amount, or a flat fee of $25–$50.
Always ask lenders for the Annual Percentage Rate (APR), which includes both the interest rate and fees. Two loans with the same stated interest rate but different fees can have meaningfully different APRs and total costs.

| SBA 504 | $5.5M (SBA) | 20 years | Commercial real estate, equipment | 5%–7% |
| SBA Microloan | $50K | 6 years | Startups, very small businesses | 8%–13% |
| SBA Express | $500K | 10 years | Fast approval (36 hours) | 11%–14% |
| SBA Export | $5M (SBA) | 25 years | Export-focused businesses | Varies |

Limitations of This Calculator
This business loan calculator provides estimates based on standard fully amortizing loan structures. It does not account for:
- Variable interest rates: SBA 7(a) loans and many conventional business loans have variable rates tied to the prime rate. Actual monthly payments may increase or decrease over time.
- Origination fees and closing costs: Not included in the payment estimate. Add them separately when comparing total loan costs between lenders.
- Balloon payments: Some commercial loans require a large lump-sum payment at the end of the term. This calculator assumes fully amortizing loans with no balloon.
- Interest-only periods: Certain loan structures allow interest-only payments for the first 12–24 months. This tool assumes principal plus interest from payment one.
- Compound frequency: This calculator uses monthly compounding. Some lenders compound interest daily, which increases the effective annual rate slightly.
For a precise loan cost analysis, consult your lender's official loan disclosure documents or a certified financial advisor (CFA) before making any borrowing decision.
