What Are SBA Loans?
SBA (Small Business Administration) loans are government-backed financing options designed to help small businesses access capital that might otherwise be unavailable through conventional lending. The SBA doesn't directly lend money; instead, it guarantees a portion of loans made by approved lenders, reducing their risk and enabling them to offer more favorable terms to small businesses.
SBA loans are renowned for their competitive interest rates, longer repayment terms, and lower down payments compared to conventional business loans. However, they also require more documentation and have longer approval times. Understanding the different SBA loan programs helps business owners choose the right financing option for their specific needs.
How SBA Loan Payments Are Calculated
SBA loans use standard amortization, similar to other fixed-rate loans:
Where P is the loan principal, r is the monthly interest rate, and n is the total number of monthly payments. SBA interest rates are typically based on the Prime Rate plus a spread determined by the loan amount and term.

Worked Example: $250,000 SBA 7(a) Loan
Let's calculate payments for a typical SBA 7(a) loan:
- Loan amount: $250,000
- Purpose: Working capital
- Term: 10 years
- Interest rate: 10.5% (Prime + 2.75%)
Calculation:
Monthly rate: 10.5% ÷ 12 = 0.875%
Number of payments: 10 years × 12 = 120
Monthly payment: $250,000 × [0.00875 × (1.00875)^120] / [(1.00875)^120 - 1] = $3,377.63
Result:
- Monthly payment: $3,377.63
- Total payments: $405,315.60
- Total interest: $155,315.60
