Small Business Administration (SBA) loans are government-backed financing options designed to help small businesses access capital. Our SBA loan calculator helps you estimate monthly payments, understand guarantee fees, and compare different SBA loan programs before applying. By entering your loan amount, interest rate, and term, you'll see the true cost of SBA financing including the SBA guarantee fee that most borrowers must pay.
SBA loans are partially guaranteed by the U.S. Small Business Administration, reducing risk for lenders and enabling more favorable terms for borrowers. The SBA doesn't lend directly—instead, it guarantees a portion of loans made by participating banks, credit unions, and online lenders. This guarantee ranges from 40% to 85% depending on the loan type. Because of this backing, SBA loans typically offer lower down payments (10-20%), longer repayment terms (up to 25 years), and competitive interest rates compared to conventional business loans.
Monthly Payment Formula
M = P × [r(1+r)^n] / [(1+r)^n - 1]SBA loans include guarantee fees of 2-3.5% that are often rolled into the loan. Our calculator shows these upfront so you know exactly what you're paying.

The SBA guarantee fee is a one-time fee paid by borrowers to the SBA for guaranteeing the loan. For 7(a) loans, it's 2% of the guaranteed portion for loans up to $1M, 3% plus 0.25% on the portion over $1M for loans $1-2M, and 3.5% plus 0.25% for loans over $2M. This fee is typically rolled into the loan amount.
7(a) loans are the most flexible, usable for working capital, equipment, and real estate up to $5M. 504 loans are specifically for fixed assets (real estate, major equipment) and combine a bank loan (50%), CDC loan (40%), and borrower equity (10%). 504 loans offer fixed rates on the CDC portion but have stricter requirements.
Most SBA lenders require a minimum credit score of 650-680, though requirements vary by lender and loan type. A score of 700+ typically qualifies for the best rates. SBA Microloans may have more flexible credit requirements since they're issued through nonprofit intermediaries.
Timeline varies by loan type: SBA Express loans can be approved in 36 hours to 2 weeks, standard 7(a) loans take 60-90 days, and 504 loans typically take 30-45 days for the CDC portion. Using an SBA Preferred Lender can speed up the process.
SBA 7(a) loan rates are typically Prime + 2.25% to 4.75% depending on loan size and term, currently around 10-13% (as of 2024). 504 loan CDC portion rates are fixed and tied to 5 and 10-year Treasury rates, typically around 6-7%. Microloans average 8-13% set by intermediary lenders.
Yes, but it's more challenging. SBA Microloans (up to $50,000) are designed for startups. For larger 7(a) loans, you'll typically need a strong business plan, relevant industry experience, personal credit score of 680+, and often a co-signer or additional collateral.
SBA loans typically require 10-20% equity injection (down payment), though exact requirements depend on the loan type and your qualifications. 504 loans specifically require 10% borrower equity, while 7(a) loans may require 10-30% depending on the use of funds and collateral.
SBA loans can fund: real estate purchase/construction, equipment and machinery, working capital and inventory, business acquisition, debt refinancing, and leasehold improvements. Each loan type has specific permitted uses—504 loans are limited to fixed assets while 7(a) loans are more flexible.
