Loans with terms of 15 years or more have a declining prepayment penalty in the first three years. - Interest on business loans is generally tax-deductible as a business expense. Keep the amortization schedule for your tax filing — total interest paid each year is the deductible portion. - Ask your lender whether the rate is fixed or variable. SBA 7(a) rates are most commonly variable, resetting quarterly with Prime. A rate hike adds to your monthly payment the following quarter. - Factor in the packaging fee. Many SBA lenders charge a one-time packaging fee (typically $2,000–$5,000) in addition to the SBA guarantee fee. Add it to the origination fee field for a complete picture. ## Frequently Asked Questions ### How do I calculate an SBA loan payment? Use the standard amortization formula: monthly payment = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is the principal, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments. For a $250,000 SBA 7(a) loan at 10.5% over 10 years (120 months), the monthly payment is about $3,374. Enter your own numbers in the calculator above for an exact figure. ### What is the SBA loan guarantee fee? The SBA charges a one-time fee on the guaranteed portion of 7(a) loans. Current tiers (fiscal year 2026): 0% on loans ≤$1,000,000, 1.45% on $1,000,001–$2,000,000 (guaranteed portion), and 3.5%+3.75% on loans above $2 million. The fee is paid at closing and can be financed into the loan principal. Enter it in the origination fee field above. ### What are current SBA 7(a) interest rates? SBA 7(a) rates are variable and tied to the Prime rate. The SBA caps the maximum margin at Prime + 3.0% to Prime + 4.5% depending on loan size and term. With Prime near 8.0% in April 2026, typical SBA 7(a) rates fall between 10.5% and 13.5%. Your actual rate depends on the lender, loan size, and your business credit profile. ### How much can I borrow with an SBA loan? SBA 7(a) loans cap at $5 million. SBA 504 loans have the same $5M cap on the CDC portion but the total project cost can be higher. SBA Express loans cap at $500,000. SBA Microloans go up to $50,000. The calculator handles any loan amount — enter what you plan to borrow. ### What are typical SBA loan terms? Terms vary by loan type and use of proceeds. SBA 7(a) allows up to 10 years for working capital and equipment, up to 25 years for commercial real estate. SBA 504 terms are 10, 20, or 25 years. SBA Express allows up to 10 years (7 years for revolving lines of credit). Enter your term in months in the calculator (25 years = 300 months). ### Are there prepayment penalties on SBA loans? SBA 7(a) loans with terms under 15 years have no prepayment penalty. Terms of 15 years or more have a declining penalty in the first three years only: 5% of the prepaid amount in year one, 3% in year two, 1% in year three, then zero. SBA 504 loans have a declining prepayment penalty over the first half of the term. ### Is SBA loan interest tax-deductible? Yes. Interest paid on business loans — including SBA loans — is generally deductible as a business expense on your tax return. Each year's deductible amount equals the total interest paid that year, which you can read directly off the amortization schedule. ### What is the effective APR shown in the calculator? Effective APR is the total cost of the loan (interest + fees) expressed as an annual percentage of the loan amount. It is higher than the quoted interest rate because it includes the SBA guarantee fee and any origination fee. Use it to compare an SBA loan with guarantee fees against a conventional loan with no fees — apples to apples. ## Related Tools - [Business Loan Calculator](https://findutils.com/finance/business-loan-calculator/) - [Loan Calculator](https://findutils.com/finance/loan-calculator/) - [Amortization Calculator](https://findutils.com/finance/amortization-calculator/) - [Mortgage Calculator](https://findutils.com/finance/mortgage-calculator/) - [Break-Even Calculator](https://findutils.com/finance/break-even-calculator/) - [Refinance Calculator](https://findutils.com/finance/refinance-calculator/) - [Compound Interest Calculator](https://findutils.com/finance/compound-interest-calculator/) - [ROI Calculator](https://findutils.com/finance/roi-calculator/)
