The Commercial Mortgage Calculator is a financial tool designed to help investors, business owners, and real estate professionals estimate the cost of financing commercial property. It calculates monthly mortgage payments, total interest, and full repayment schedules based on loan amount, interest rate, and term.
Commercial real estate loans are often large and long-term commitments. Without proper planning, they can significantly impact business cash flow. This calculator helps users understand affordability before committing to a property purchase.

What Is a Commercial Mortgage?
A commercial mortgage is a loan used to purchase or refinance business property such as:

Unlike residential mortgages, commercial mortgages are:
- Based on business income
- Higher in value
- Shorter amortization periods
- Higher interest rates
How the Commercial Mortgage Calculator Works
The calculator uses the standard amortization formula to estimate repayment.
Core Formula:
Monthly Payment =
P × r × (1 + r)^n / ((1 + r)^n − 1)
Where:
- P = Loan amount
- r = Monthly interest rate
- n = Total number of payments
