How to Choose the Right Loan Calculator

Not all loans work the same way. Before you plug in numbers, make sure you're using the right tool for your situation.

SBA Loans vs. Conventional Business Loans

SBA loans (7(a) and 504) are partially guaranteed by the federal government, which lets lenders offer lower rates and longer terms than a conventional bank loan — but the application is more involved and approval can take weeks. Use the SBA Loan Calculator if you're applying through an SBA-approved lender and need to model exactly what the government-backed repayment looks like.

Conventional business loans are faster to obtain but typically carry higher rates and shorter terms. Use our Business Loan Calculator to compare both scenarios side-by-side so you can see which saves you more over the full repayment window.

Secured vs. Unsecured Loans — Why the Rate Differs

Secured loans (SBA, land, auto, RV) are backed by collateral — the lender can claim the asset if you default. Because the lender's risk is lower, rates are lower. Unsecured loans (personal loans, some business lines of credit) carry no collateral, so interest rates run higher — typically 10%–36% depending on credit. Always run both scenarios through the appropriate calculator before committing, to determine total cost of borrowing, not just monthly payment size.

What to Look for in Any Loan

Monthly payment is only one number. Before signing, confirm these five factors with your lender:

1. APR vs. interest rate. The interest rate is the base cost of borrowing. The APR (Annual Percentage Rate) includes fees like origination charges, SBA guarantee fees, and closing costs — it's the true annual cost. Always compare APRs across lenders, not just rates.
2. Origination and guarantee fees. SBA 7(a) loans carry a guarantee fee of 0.5%–3.5% of the guaranteed portion, depending on loan size and term. Conventional lenders may charge 1%–5% origination. These are often financed into the loan — meaning you pay interest on them for the full term.
3. Prepayment penalties. SBA 7(a) loans with terms ≥15 years have a sliding prepayment fee in years 1–3 (5% / 3% / 1%). Many conventional lenders charge a flat prepayment fee. If there's any chance you'll refinance or pay off early, factor this in.
4. Variable vs. fixed rate. Variable rates (common with SBA 7(a)) can drop if Prime falls — but also rise. Fixed rates give payment certainty for the full term. Model both with the calculator above using your lender's quoted ceiling rate to stress-test your budget.
5. Total cost of borrowing. A longer term lowers your monthly payment but dramatically increases total interest paid. Use the calculator's "Total Amount Paid" figure — not just the monthly payment — when comparing loan offers.
