How are commercial real estate loans different from residential?
Commercial loans are underwritten primarily on property income (NOI and DSCR) rather than personal income. They typically require 25-35% down, carry 5-10 year balloon terms with 25-30 year amortization, and price based on property type, cash flow stability, and borrower experience.
Best for: Investors purchasing office, retail, industrial, or mixed-use commercial properties
How It Works
Understanding the Commercial CRE Calculator
Commercial real estate loans differ fundamentally from residential mortgages in structure, underwriting, and term. This calculator models the unique characteristics of commercial financing — including balloon terms, interest-only periods, and income-based qualification.
Worked example: You're purchasing a 10,000 sq ft retail strip center for $2,200,000 with 30% down ($660,000). Loan: $1,540,000 at 7.25%, 25-year amortization with a 10-year balloon. Monthly P&I: $11,126. The property generates $22,000/month in gross rental income. After 35% operating expenses ($7,700), NOI is $14,300/month. DSCR = $14,300 / $11,126 = 1.29 — above the 1.25 threshold. At the 10-year balloon, remaining balance is approximately $1,225,000.
The calculator supports purchase prices up to $25 million and lets you model amortization periods from 15-30 years and balloon terms from 3-10 years. Pair with our DSCR Calculator for a deeper income analysis.

About This Calculator
What the Commercial CRE Calculator is For
Commercial real estate underwriting is driven by property-level income, not borrower W-2s. This calculator puts the core CRE metrics in one place: enter your property value, loan amount, rate, and amortization to see your monthly debt service and LTV instantly. Open the NOI panel to input gross income, vacancy, management fees, taxes, insurance, and maintenance — the calculator derives NOI, DSCR, cap rate, and debt yield in real time. Toggle between refinance and purchase modes, compare 15- through 30-year amortization schedules, and model interest-only structures for bridge and transitional deals. The built-in amortization table shows principal paydown year by year.
Common Use Cases
- Analyzing a CRE acquisition or refinance before submitting a loan request
- Calculating DSCR, cap rate, and debt yield on an income-producing commercial property
- Comparing amortization terms (15, 20, 25, 30 yr) and interest-only structures
- Modeling how rate changes or NOI improvements affect commercial deal qualification
- Stress-testing different LTV scenarios for conventional CRE, bridge, or construction loans

Selling a home and buying another one at the same time is one of the most logistically complicated things most people do in their financial lives.
