What Is an SBA Loan?

An SBA loan is a small business loan partially guaranteed by the U.S. Small Business Administration. These loans are commonly used for:

• Business expansion
• Equipment purchases
• Real estate investments
• Working capital
• Startup funding
• Debt refinancing

SBA loans are popular because they often offer:

• Lower interest rates
• Longer repayment terms
• Flexible financing options
• Easier qualification compared to traditional loans

The calculator helps borrowers understand the financial impact of these loans before committing.

How to Use the SBA Loan Calculator

Using the SBA Loan Calculator is easy and requires only a few inputs.

Step 1: Enter the Loan Amount

Input the total amount you want to borrow for your business.

Example:

• $50,000
• $150,000
• $500,000

This amount becomes the base for all calculations.

Step 2: Add the Interest Rate

Enter the annual interest rate offered by your lender.

Example:

• 5%

The calculator uses this rate to estimate monthly payments and total interest.

Step 3: Enter the Loan Term

Choose how long you plan to repay the loan.

Examples:

• Monthly payments
• Total interest costs

Step 6: Enter Extra Monthly Payments (Optional)

You can include additional monthly payments to see how early repayment affects the loan.

Extra payments can:

• Reduce total interest
