How the Business Loan Calculator Works

This business loan calculator uses the standard fixed-rate amortization formula to compute your monthly payment for a commercial or small business loan, then builds a full repayment schedule showing how much of each payment goes to principal versus interest.

Formula

Monthly Rate (r) = Annual Rate / 12 / 100
Number of Payments (n) = Term in Months
Monthly Payment = P × r × (1 + r)ⁿ / [(1 + r)ⁿ − 1]
(If r = 0: Monthly Payment = P / n)

Worked Example

A $100,000 small business loan at 8% annual interest over 5 years (60 months): monthly payment ≈ $2,027.64, total repayment ≈ $121,658, and total interest ≈ $21,658 over the life of the loan.

How to Use This Business Loan Calculator

  1. Enter the loan amount you're borrowing (commercial or small business loan principal).
  2. Enter the annual interest rate offered by the lender.
  3. Choose years or months, then enter the loan term.
  4. If your lender charges an origination fee, enter it as a percentage to see its dollar cost.
  5. Your monthly payment, total interest, and a 12-month repayment schedule preview appear instantly.

Frequently Asked Questions

What's the difference between a business loan and a commercial loan?

"Business loan" and "commercial loan" are often used interchangeably to describe financing for a business, though "commercial loan" sometimes specifically refers to larger loans for commercial real estate or equipment. This calculator works for either.

What is a typical interest rate on a small business loan?

Rates vary widely based on the lender, loan type, your business credit, and collateral — anywhere from roughly 6% to 30%+ depending on the loan product (bank term loan, SBA loan, or online/alternative lender).

What is an origination fee?

An origination fee is a one-time charge some lenders deduct from your loan amount (or add to your closing costs) for processing the loan, typically expressed as a percentage of the loan amount.

Does a shorter repayment term save money on a business loan?

Generally yes — a shorter term means less time for interest to accrue, so total interest paid is lower, though the monthly payment will be higher.
