Business Loan Calculator
Calculate commercial business loan periodic payments, cumulative interest, total cost with upfront closing & documentation fees, and fee-adjusted Real True APR with interactive amortization schedule.
Business Loan Calculator
The Business Loan Calculator calculates the payback amount and the total costs of a business loan. The calculator can also take the fees into account to determine the true annual percentage rate, or APR for the loan. The APR gives borrowers a more accurate assessment of a loan's actual cost.
• Input your principal loan amount, nominal interest rate, compounding schedule, and payback frequency.
• Add origination, documentation, and administration fees to reveal the True Real APR.

Understanding Commercial Business Loans and Real APR
Business loans allow enterprises to fund capital expenditures, expand operations, or bridge working capital. When comparing loan proposals from commercial banks, SBA lenders, or alternative fintech platforms, comparing nominal interest rates alone can be misleading because upfront closing and origination fees significantly increase the true cost of borrowing.
Nominal Rate vs. Real APR
The nominal interest rate is the base percentage charged on the principal balance. The Real APR (Annual Percentage Rate) incorporates all mandatory upfront fees (origination, documentation, packaging), expressing the true annualized cost of capital.
SBA 7(a) and 504 Financing
US Small Business Administration (SBA) loans provide government-backed guarantees that lower interest rates for small businesses. However, SBA loans often carry statutory guaranty fees (up to 3.75%) that must be factored into the overall loan cost.
Debt Service Coverage (DSCR)
Lenders assess your business's ability to service debt using the Debt Service Coverage Ratio (Net Operating Income / Total Debt Service). Most commercial institutions require a minimum DSCR of 1.25x before approving term loans.

Business Loan Calculator — Frequently Asked Questions
Q1 What is the difference between Nominal Interest Rate and Real APR on a business loan? ▾
The nominal interest rate is the base percentage applied to your outstanding principal balance to calculate periodic interest charges. The Real APR (Annual Percentage Rate) incorporates all mandatory upfront fees (origination, documentation, packaging, underwriting), expressing the true annualized cost of capital.
Q2 What fees are typically charged on commercial and SBA business loans? ▾
Common business loan fees include loan origination fees (typically 1% to 6%), SBA statutory guaranty fees (up to 3.75%), packaging/documentation fees ($500 to $2,500), appraisal fees for commercial real estate, and legal closing costs.
Q3 How does payment frequency affect total business loan interest? ▾
Making more frequent payments (such as weekly or bi-weekly instead of monthly) reduces the outstanding principal balance faster, resulting in lower cumulative interest paid over the life of the commercial loan.
Q4 What is the Debt Service Coverage Ratio (DSCR) and why do lenders require it? ▾
DSCR measures a business's available cash flow to cover debt obligations (Net Operating Income / Total Debt Payments). Commercial lenders typically require a minimum DSCR of 1.20x to 1.35x before approving term financing.
Q5 Are business loan interest and fees tax-deductible? ▾
In many jurisdictions including the United States, commercial loan interest and amortized loan origination expenses incurred for legitimate business purposes are generally tax-deductible as operating expenses. Consult a CPA or tax advisor for your specific tax situation.
