Commercial Mortgage Calculator
Estimate the monthly payment and total interest on a commercial property mortgage, amortized over 20–25 years. Most commercial mortgages have a balloon — a long amortization but a shorter term — so read the balance column at your term's end to see the balloon you'll refinance or pay off. Free, no signup.

Frequently asked questions
- How does a commercial mortgage differ from a home mortgage?
- Commercial mortgages are underwritten on the property's income and the business, not a household. They typically carry shorter terms with a balloon (e.g. amortized over 25 years but due in 10), require larger down payments (often 20–35%), and price on the debt-service-coverage ratio. Rates and terms vary far more than residential.
- How do I find the balloon payment?
- Enter the full amortization period (e.g. 25 years) as the term, then open the amortization schedule and read the balance column at the month your actual loan term ends (e.g. month 120 for a 10-year term). That remaining balance is the balloon you'll refinance or repay.
- Does this account for property taxes, insurance, or fees?
- No — it shows principal and interest only. Commercial mortgages often escrow taxes and insurance and charge origination, appraisal, and legal fees separately. Treat the result as the P&I floor and confirm the all-in cost with your lender.
