How to use the Commercial Loan Calculator

The Commercial Loan Calculator is free and runs entirely in your browser — no sign-up, and nothing you enter leaves your device. It opens pre-filled with a realistic example, so you can see how it works before replacing any figure with your own; the results update as you type. Press Calculate to refresh the result panel, or Reset to return to the example.

The inputs it asks for:

  • Loan Amount — a dollar amount.
  • Annual Interest Rate — a percentage (enter 6 for 6%).
  • Amortization Period (yrs) — a number.
  • Balloon / Loan Term (yrs) — a number.

Worked example

Using the example values — Loan Amount $1,000,000.00, Annual Interest Rate 6.5%, Amortization Period (yrs) 25, Balloon / Loan Term (yrs) 5 — the Commercial Loan Calculator returns a Monthly Payment of $6,752.07. It also reports Balloon Payment Due ($905,621.63), At End of (Years) (5), Interest Paid Before Balloon ($310,745.93).
