Business Loan Calculator

About the Business Loan Calculator

Financing a business purchase, equipment, real estate, or working capital requires a clear understanding of the true cost of borrowing. Our business loan calculator handles all common loan structures: term loans, SBA 7(a) and 504 loans, equipment financing, and lines of credit. Understanding your debt service coverage ratio (DSCR) and monthly cash flow impact is essential before taking on any business debt.

How It Works

Business loans use the same amortization mathematics as personal loans, but with additional considerations: loan fees (origination, guarantee fees) affect the true APR, balloon payments are common in commercial real estate loans, and the tax deductibility of interest reduces the effective cost. SBA 7(a) loans have rates of prime + 2.25–4.75% with terms up to 25 years for real estate and 10 years for working capital.

Tips & Best Practices

• ✓SBA loans offer the best rates and terms for small businesses but require strong credit and documentation.
• ✓The debt service coverage ratio (DSCR) must be at least 1.25× for most commercial lenders.
• ✓Business loan interest is fully tax-deductible as a business expense, reducing effective borrowing cost.
• ✓Equipment financing often requires only the equipment itself as collateral.
• ✓Invoice factoring and revenue-based financing are alternatives when traditional loans aren't available.

Who Uses This Calculator

Small business owners evaluating expansion financing, entrepreneurs modeling startup costs, and commercial real estate investors underwriting acquisition loans all benefit from accurate business loan payment modeling.
