SBA Loan Calculator
Estimate your SBA loan monthly payment in seconds
Use LendingTree’s SBA loan calculator below to estimate your monthly payment based on loan amount, interest rate and term. SBA loans typically have repayment terms of up to 10 years (or 25 years for real estate), and payments depend heavily on your rate and repayment period.
An SBA loan calculator helps estimate your monthly payment before applying for financing. By adjusting the loan amount, interest rate and term, you can compare scenarios and find a payment that fits your business budget.
SBA loan calculator limitations
Our SBA loan calculator provides an estimate, but your actual loan terms may differ for several reasons:
Interest rate
Your interest rate depends on the lender and your credit profile. Because the lender sets the final rate, your actual monthly payment may be higher or lower than the calculator estimate.
Guaranty and service fees
SBA loans may include guaranty or service fees that lenders sometimes pass on to borrowers. These fees typically range from 0% to about 3.75% of the loan amount, depending on the lender, loan size and terms. Because the calculator doesn’t include these fees, your actual payment may be higher than the estimate.
Funding time
SBA loans can take 30 to 90 days to fund. This calculator estimates payments only and doesn’t reflect how long it may take to receive funding.

How to use the SBA loan calculator
The SBA loan calculator estimates your monthly payment using three inputs: loan amount, interest rate and loan term.
1. Loan amount
Enter how much you plan to borrow. SBA 7(a) loans typically allow up to $5,000,000, while SBA 504 loans can reach $5,500,000 for real estate and other fixed assets. Adjusting the loan amount in the calculator shows how different borrowing levels affect your monthly payment.
Borrow only what you need to avoid taking on unnecessary debt and to keep your monthly payment as low as possible.
2. Interest rates
Enter your interest rate or APR to estimate your monthly payment. SBA loan interest rates are negotiated between the lender and borrower, but the SBA sets maximum allowable rates.
Fixed interest rates
| Loan amount | Maximum interest rate |
|---|---|
| $0 to $25,000 | 14.75% |
| $25,001 to $50,000 | 13.75% |
| $50,000 to $250,000 | 12.75% |
| Greater than $250,000 | 11.75% |
Variable interest rates
| Loan amount | Minimum interest rate |
|---|---|
| $50,000 or less | 13.25% |
| $50,001 to $250,000 | 12.75% |
| $250,001 to $350,000 | 11.25% |
| Greater than $350,000 | 9.75% |
If you already have a loan offer, enter the annual percentage rate (APR). If not, you can estimate a rate to see how it affects your payment. The calculator doesn’t include lender fees, so your actual costs may vary.
SBA 7(a) rates are typically tied to the prime rate, while SBA 504 rates are based on U.S. Treasury yields, so the rate you receive may change as market rates move.
3. Loan term
Enter your loan term. Longer terms typically mean lower monthly payments but more interest over time, while shorter terms mean higher payments but less total interest.
Most SBA 7(a) loans have terms of up to 10 years, or up to 25 years if the loan is used for real estate. SBA 504 loans typically have terms of 10, 20 or 25 years.
Use the calculator to see how different loan terms affect your monthly payment and total cost.
Example SBA loan payment
Loan amount: $150,000
Interest rate: 10%
Loan term: 10 years
Estimated monthly payment: $1,982.26
This example is for illustration only. Use the calculator above to estimate your own payment.
Each SBA loan payment typically covers both interest and principal. Early in the loan term, a larger portion of your payment goes toward interest. Over time, more of each payment goes toward the principal balance.
This breakdown is called an amortization schedule, which shows how your payments are applied over the life of the loan. After using the calculator, you can review the payment schedule to see how your payments may change over time.
