An SBA loan is a business loan partially guaranteed by the U.S. Small Business Administration. It helps small businesses access funding with favorable terms, such as lower down payments and longer repayment periods.

What does the SBA guarantee fee cover?

The guarantee fee is a one-time fee charged by the SBA to guarantee a portion of your loan. It helps reduce lenders' risk, making it easier for small businesses to qualify.

How does the interest rate affect my SBA loan payments?

A higher interest rate increases your monthly payment and the total interest paid over the life of the loan. Even small rate changes can significantly impact long-term costs.

Understanding SBA Loans

A Small Business Administration (SBA) loan is a government-backed loan designed to help small businesses access affordable funding.

These loans are used for business expansion, equipment purchases, working capital, or even refinancing existing debt. SBA loans often offer lower down payments, longer repayment terms, and competitive interest rates compared to many traditional business loans.

However, understanding the true cost of an SBA loan, including monthly payments, interest, and fees, can be challenging.

Many business owners want to know exactly how much they’ll pay each month, how much interest will accrue, and what fees are involved. This calculator is designed to provide clarity and help you make informed borrowing decisions before committing to a loan.

How This Calculator Helps

This SBA Loan Calculator is built to give you a clear picture of what to expect when considering an SBA loan. By entering your loan amount, interest rate, and loan term, you’ll instantly see:

The one-time SBA guarantee fee you’ll pay up front
Your estimated monthly loan payment
The total interest you’ll pay over the life of the loan

Beyond these key figures, the calculator provides interactive charts and detailed schedules. You can see how your remaining balance changes year by year, how much of each payment goes to principal versus interest, and review a full amortization schedule. Tools for copying results or exporting them as PDF or Excel files make it easy to save or share your estimates.
