Our Business Loan Payment Calculator helps small business owners estimate monthly payments on term loans, SBA loans, equipment financing, and commercial real estate loans. Understanding your debt service is essential for maintaining healthy business cash flow.
Business loan rates in 2025 vary widely — from 6–7% on SBA 504 loans to 30%+ on short-term online business loans. The right loan depends on your business age, revenue, credit profile, and what the funds will be used for.

Enter the interest rate quoted by your lender, SBA, or business bank.
Enter the loan term — equipment loans are typically 5–7 years; commercial real estate up to 25 years.

Our calculator uses the standard loan amortization formula used by all US banks, mortgage lenders, and credit unions:
Each payment covers two components: interest (charged on your remaining balance) and principal (which reduces your balance). In the early months, more of your payment goes toward interest. As your balance decreases, more goes toward principal — this is called front-loaded interest amortization.
Business loans come in many forms: term loans, SBA loans, lines of credit, and equipment financing. Each serves a different purpose. Term loans work best for large one-time investments like equipment or expansion. Lines of credit are better suited for managing day-to-day working capital needs where the amount required varies month to month.
SBA 7(a) loans offer some of the most competitive rates for small businesses — currently around 10.5 to 13 percent — because the SBA guarantees a portion of the loan, reducing lender risk. The trade-off is a longer approval process and more documentation. If you need funding quickly, a conventional bank loan or online business lender may be faster.
Lenders evaluate business loans based on time in business (typically 2 years preferred), annual revenue, the owner's personal credit score, and debt-service coverage ratio (DSCR). A DSCR of 1.25 or higher — meaning your business earns $1.25 for every $1 of debt payment — is the standard approval benchmark.
Always compare the total cost of a loan, not just the rate. Origination fees and prepayment penalties can significantly increase the true cost of borrowing. If you have commercial real estate to use as collateral, our Commercial Loan Calculator shows how secured rates compare. For smaller unsecured amounts, our Personal Loan Calculator can help evaluate financing options for owner-operators.
