Use the calculator beside this guide for your own values. The workflow is educational and does not replace a quote, contract, appraisal, or professional review.
Build the complete baseline
Commercial loans often amortize longer than their contractual maturity. Review monthly debt service, DSCR, leverage, fees, and the remaining balloon together.
- Separate amortization from maturity.
- Use lender-adjusted NOI when available.
- Plan for refinance or payoff of the balloon.
Test the assumptions that can change
Save a baseline, then run a conservative case and an alternative. A decision that changes after a small adjustment needs more margin or better source information.
Verify before acting
Use the commercial mortgage calculator: payment & balloon to organize the numbers, then compare the result with current documents, official rules, and provider-specific terms.
