About This Commercial Loan Payment Calculator

Our Commercial Loan Payment Calculator helps business owners, real estate investors, and developers estimate monthly payments on commercial mortgages, equipment loans, and business property financing. Commercial real estate loans have different structures than residential mortgages and require careful financial planning.

Unlike home loans, commercial loans are evaluated primarily on the property's income-generating ability (Net Operating Income) and the borrower's business financial strength. Most commercial loans have 20–25 year amortization schedules but balloon (come fully due) in 5–10 years.

How to Use This Calculator

1

Enter the loan amount (commercial property value minus your down payment).

2

Enter the interest rate — often tied to SOFR, Prime Rate, or Treasury yields plus a spread.

3

Enter the amortization period — typically 20–25 years for commercial real estate loans.

4

Click Calculate to see your monthly payment and remember to plan for the balloon payment at term end.

How the Payment Formula Works

Our calculator uses the standard loan amortization formula used by all US banks, mortgage lenders, and credit unions:

// Standard Amortization Formula M = P × [ r(1+r)ⁿ ] / [ (1+r)ⁿ − 1 ]

// Variables: M = Monthly payment amount P = Principal (loan amount) r = Monthly interest rate (APR ÷ 12 ÷ 100) n = Total number of monthly payments (term in months)

Each payment covers two components: interest (charged on your remaining balance) and principal (which reduces your balance). In the early months, more of your payment goes toward interest. As your balance decreases, more goes toward principal — this is called front-loaded interest amortization.

What to Know Before Taking a Commercial Loan

Commercial loans are used to purchase, refinance, or improve income-producing real estate such as office buildings, retail centers, and apartment complexes. Unlike residential mortgages, commercial loans are evaluated primarily on the income generated by the property rather than the personal income of the borrower.

The key metric lenders use is the Debt Service Coverage Ratio (DSCR): net operating income divided by annual loan payments. Most lenders require a DSCR of at least 1.25, meaning the property generates 25 percent more income than needed to cover the loan. A higher ratio improves approval odds and may unlock better interest rates.

Commercial loan structures differ significantly from residential mortgages. Amortization periods of 20 to 25 years are common, but loans often have balloon payments due after 5, 7, or 10 years — meaning the remaining balance must be refinanced or repaid in full at the balloon date. Factor this into long-term cash flow projections.

Use this calculator to model different rate and term scenarios before approaching a lender. For businesses that also need operating capital, our Business Loan Calculator covers term loans and SBA options. Property owners looking to tap equity without a full refinance should explore our HELOC Calculator for flexible alternatives.

Frequently Asked Questions

Debt Service Coverage Ratio (DSCR) = Net Operating Income (NOI) ÷ Annual Debt Service. Most commercial lenders require a minimum DSCR of 1.20–1.25, meaning the property generates at least 20–25% more income than needed to cover loan payments. A DSCR below 1.0 means the property can't cover its own debt — a major red flag for lenders.
Many commercial loans have a shorter term (5–10 years) than their amortization period (20–25 years). When the term ends, the entire remaining principal balance becomes due as a 'balloon payment.' Borrowers typically refinance or sell the property before the balloon comes due. Always have a clear exit strategy before taking a balloon commercial loan.
Common commercial loan types include: conventional commercial mortgages (from banks), SBA 504 loans (owner-occupied commercial real estate, up to $5.5M), SBA 7(a) loans (general business purposes, up to $5M), CMBS loans (securitized, for larger properties), bridge loans (short-term financing), construction loans, and commercial hard money loans (asset-based, for quick closings).
Commercial underwriting focuses primarily on the property's income potential (NOI, cap rate, DSCR) rather than just the borrower's personal finances. Lenders evaluate the property's occupancy rate, lease terms, tenant quality, and market conditions. The borrower's business financial strength, global cash flow, and net worth are also evaluated. Environmental assessments and professional appraisals are typically required.
Commercial loan closing costs typically run 2–5% of the loan amount and include: origination fee (0.5–2%), appraisal ($2,000–$10,000+), environmental assessment ($1,500–$5,000), title insurance, legal fees, and lender processing fees. SBA loans have additional guarantee fees (0.5–3.5% of the guaranteed portion). Always request a complete fee breakdown before committing to a lender.
