Business & SBA Loan Calculator
See the real cost of borrowing before you sign. Estimate your monthly payment, total interest and origination fee for a term loan or SBA loan — and check whether the offer in front of you is actually a good deal.
How this business loan calculator works
The tool treats your financing as a standard amortizing loan: a fixed monthly payment that covers interest first and chips away at principal over the term. The math is the same one banks and SBA lenders use, so the numbers should line up closely with a real offer that shares the same amount, rate and term.
- Monthly payment — calculated from your loan amount, annual rate and the number of months (term × 12) using the standard amortization formula.
- Total interest — every payment added up, minus the amount you borrowed. This is the price of the money over the full term.
- Origination fee — a one-time charge most lenders take, shown here as a percentage of the loan amount. Some lenders deduct it from your proceeds, so you receive slightly less than the face amount.
- Total cost — all your payments plus the origination fee, so you can see the true all-in number rather than just the monthly figure.
Business loan FAQs
An SBA 7(a) loan typically offers the lowest rates and the longest terms but takes the longest to fund and requires the most paperwork. A conventional term loan funds faster and suits a one-time investment such as equipment or an expansion. A business line of credit is best for ongoing or unpredictable needs because you draw and repay as you go and pay interest only on the balance you use.
Rates vary widely by loan type and credit profile. SBA 7(a) loans are commonly in the high single digits to low teens, bank term loans are often similar for strong borrowers, and online or short-term lenders can run much higher. Your rate depends on credit score, time in business, revenue, collateral and the lender — so treat any single figure as an estimate and compare offers.
Lenders typically weigh your personal and business credit, time in business (often two or more years for the best terms), annual revenue and cash flow, debt-service coverage, and available collateral or a personal guarantee. Strong, well-documented financials usually unlock lower rates and larger amounts.
Online lenders can fund a term loan or line of credit in as little as one to a few business days. Conventional bank loans often take a couple of weeks. SBA loans usually take the longest — frequently several weeks to a couple of months — because of the extra underwriting and the government guarantee process.
