What Is a Business Loan?
A business loan is a fixed sum of money borrowed from a bank, credit union, or online lender. The business repays it over a set period with scheduled payments covering both principal (the amount borrowed) and interest (the lender's fee). Most business loans use an amortization schedule. Early payments are mostly interest; later payments are mostly principal, but the monthly amount stays fixed throughout the term.
The Federal Reserve's Senior Loan Officer Opinion Survey tracks small business lending conditions. Commercial and industrial loan rates typically range from 5% to 13%, depending on creditworthiness and loan type.

Business Loan Types and Terms
This commercial loan calculator works for all major loan types. Use the table below to choose the correct rate and term for your scenario. The tool also functions as an sba 504 loan calculator for equipment and commercial real estate purchases.
| Loan Type | Typical Amount | Typical Rate | Typical Term |
|---|---|---|---|
| SBA 7(a) Working Capital | Up to $5,000,000 | 11.5% to 15.0% | 10 years |
| SBA 7(a) Real Estate | Up to $5,000,000 | 11.5% to 14.0% | Up to 25 years |
| SBA 504 Equipment and Real Estate | $125,000 to $5,500,000 | 6.0% to 8.5% | 10 to 25 years |
| SBA Microloan | Up to $50,000 | 8.0% to 13.0% | Up to 6 years |
| Conventional Term Loan | $10,000 to $500,000+ | 6.0% to 25.0% | 1 to 10 years |
| Business Line of Credit | $10,000 to $250,000 | 10.0% to 30.0% | Revolving |
| Equipment Loan | Up to 100% of value | 4.0% to 20.0% | 2 to 7 years |
SBA 7(a) Loan Monthly Payments
Use this sba 7a loan calculator to model any SBA scenario before you apply. An SBA 7(a) loan of $200,000 at 9.5% interest over 7 years (84 months) carries a monthly payment of $3,175. Over the full term, you pay $66,700 in interest on top of the $200,000 principal, for a total repayment of $266,700. The SBA sets maximum rate caps tied to the Wall Street Journal prime rate. Your actual rate moves within that band based on loan size and lender margin.
For working capital, the SBA allows terms up to 10 years. For real estate, terms extend to 25 years, which significantly reduces the monthly burden. A $500,000 SBA 7(a) real estate loan at 9.5% costs approximately $4,355 per month over 25 years, versus $7,938 per month over 10 years. Use the small business loan calculator above to compare these scenarios side by side.
Monthly Payment on a $1 Million Dollar Business Loan
A $1,000,000 business loan at 9% interest over 10 years produces a monthly payment of approximately $12,668. Total interest paid over the life of the loan reaches about $520,160, bringing total repayment to $1,520,160. At 7% over the same 10-year term, the monthly payment drops to $11,611, saving roughly $126,000 in interest. On large commercial loans, a 1% rate reduction produces material savings. Use the business loan payment calculator above to run both scenarios before negotiating.
Business Loan Interest Rates by Credit Score
Your personal FICO score and business credit score are the primary factors lenders use to price a business loan. Borrowers with stronger credit access SBA programs at near-prime rates; weaker credit pushes you toward alternative lenders at significantly higher rates.
| Personal FICO Score | Typical Rate Range | Likely Loan Type |
|---|---|---|
| 750 and above | 5.5% to 9.0% | SBA 7(a), conventional bank |
| 700 to 749 | 8.0% to 13.0% | SBA 7(a), credit union |
| 650 to 699 | 12.0% to 22.0% | Online lender, SBA Microloan |
| 600 to 649 | 18.0% to 30.0% | Alternative lender |
| Below 600 | Denial or 30%+ | Microfinance, CDFIs only |
A business with a PAYDEX score of 80 or above (the business credit equivalent of a strong FICO) qualifies for the best available commercial rates. Building business credit separately from personal credit is one of the most effective ways to lower future borrowing costs.
How Much Business Loan Can I Get?
Most lenders cap loan amounts at 10% to 25% of annual gross revenue. The other key metric is the Debt Service Coverage Ratio (DSCR): annual net operating income divided by total annual debt payments. A DSCR of 1.25 is the standard minimum requirement, meaning for every $1.00 in debt payment the business must generate at least $1.25 in income.
- $100,000 annual revenue: qualifies for $10,000 to $25,000 from a conventional lender.
- $500,000 annual revenue: qualifies for $50,000 to $125,000 (conventional) or up to $500,000 with SBA backing and strong collateral.
- $1,000,000 annual revenue: qualifies for $100,000 to $250,000 (conventional) or up to $1,000,000+ through SBA 7(a).
Collateral also affects how big of a business loan you can get. Real estate, equipment, and inventory all count toward collateral value. Unsecured loans, those with no collateral, are available but typically carry higher rates and lower limits. For commercial real estate financing, a commercial mortgage loan calculator gives a more precise estimate. Those loans use different amortization conventions than standard term loans.
Business Loan Amortization: How Payments Break Down
A business loan amortization calculator reveals how each payment is divided over time. In the early months of the loan, the majority of each payment goes toward interest. As the principal reduces, the interest portion shrinks and more of each payment retires the principal.
Example: A $100,000 loan at 8% for 5 years (60 months) has a fixed monthly payment of $2,028.
| Month | Payment | Principal | Interest | Balance Remaining |
|---|---|---|---|---|
| 1 | $2,028 | $1,361 | $667 | $98,639 |
| 12 | $2,028 | $1,450 | $578 | $85,498 |
| 24 | $2,028 | $1,548 | $480 | $70,671 |
| 36 | $2,028 | $1,651 | $377 | $54,600 |
| 48 | $2,028 | $1,762 | $266 | $37,187 |
| 60 | $2,028 | $1,882 | $146 | $0 |
Total interest on this loan: $21,680. Total repayment: $121,680. The amortization table helps you decide when to make extra principal payments. Early in the loan, each extra dollar has the greatest impact on reducing total interest paid.
Business Loan Fees to Know Before You Borrow
The interest rate is only part of the true cost. These fees raise the effective APR above the quoted rate and must be factored into any business loan interest rate calculator comparison:
- Origination fee: 1% to 6% of the loan amount, charged upfront. A 3% fee on a $100,000 loan adds $3,000 to your borrowing cost immediately.
- Documentation fee: $150 to $500 flat charge for processing paperwork.
- Prepayment penalty: SBA 7(a) loans over 15 years charge 5% in year one, 3% in year two, and 1% in year three if repaid early.
- Packaging fee: Charged by SBA lenders to prepare the loan application, typically $2,500 to $4,000 for larger loans.
- Annual fee: Common on a business line of credit calculator scenario, typically 1% to 2% of the credit limit per year.
Always compare Annual Percentage Rate (APR) across lenders, not just the stated interest rate. APR includes all fees and reflects the true annual cost of borrowing.
Startup Business Loan Calculator: What Changes for New Businesses?
For startups (under 2 years in business), most SBA and conventional lenders add a risk premium and require additional documentation. The same business finance calculator formula applies, but expect these differences:
- Rates 3% to 7% higher than an established business with the same credit score.
- Personal guarantee required in almost every case.
- Shorter terms (1 to 3 years) until operating history is established.
- SBA Microloan (up to $50,000) as the most accessible program for early-stage businesses.
A startup borrowing $50,000 at 12% for 3 years (36 months) pays $1,660 per month and $9,760 in total interest over the term.
Limitations of This Calculator
This commercial loan calculator uses standard amortization math and provides estimates only. Actual loan costs depend on factors the tool cannot model:
- Variable rates: SBA loan rates adjust with the prime rate. This calculator assumes a fixed rate throughout the term.
- Balloon payments: Some commercial loans require a large final lump-sum payment. This is not modeled here.
- Daily compounding: Some lenders compound interest daily rather than monthly, which slightly raises the effective rate above what the calculator shows.
- Collateral and guarantees: These affect whether you qualify, not the payment estimate.
- Tax deductions: Business loan interest is generally tax-deductible under IRS Topic 505. A tax professional can calculate the after-tax cost, which is lower than the gross interest figure shown here.
