P = principal (loan amount minus down payment)
r = monthly interest rate
n = total number of payments (months)

What is a Commercial Building Mortgage?

A commercial building mortgage is a loan specifically designed for purchasing, refinancing, or renovating commercial real estate properties such as offices, retail centers, warehouses, and industrial buildings. Unlike residential mortgages, commercial mortgages often have different terms, interest rates, and qualification criteria.


How Does the Commercial Building Mortgage Calculator Work?

By inputting your loan amount, interest rate, loan term, and payment frequency, the calculator applies standard amortization formulas to provide:

  • Estimated monthly or periodic mortgage payments
  • Detailed breakdown of principal and interest components
  • Total interest paid over the loan period
  • Amortization schedule showing remaining loan balance over time

The Core Mortgage Payment Formula

The monthly mortgage payment MMM is calculated using the amortization formula: M=P×r(1+r)n(1+r)n−1M = P \times \frac{r(1 + r)^n}{(1 + r)^n – 1}M=P×(1+r)n−1r(1+r)n​

Where:

  • MMM = monthly payment
  • PPP = loan principal amount
  • rrr = monthly interest rate (annual rate divided by 12)
  • nnn = total number of payments (loan term in months)

How to Use the Commercial Building Mortgage Calculator

  1. Enter Loan Amount: The principal loan amount.
  2. Input Interest Rate: Annual interest rate (APR) as a percentage.
  3. Specify Loan Term: The loan duration in years or months.
  4. Choose Payment Frequency: Usually monthly, but options may include quarterly or annual.
  5. Calculate: View your estimated mortgage payment, amortization breakdown, and total interest.

Example Calculation

Let’s assume you have a $2,000,000 commercial building mortgage with a 5.5% annual interest rate over 20 years, with monthly payments.

  • Loan Amount, P=2,000,000P = 2,000,000P=2,000,000
  • Monthly Interest Rate, r=5.5%12=0.004583r = \frac{5.5\%}{12} = 0.004583r=125.5%​=0.004583
  • Number of Payments, n=20×12=240n = 20 \times 12 = 240n=20×12=240

Calculate monthly payment MMM: M=2,000,000×0.004583(1+0.004583)240(1+0.004583)240−1≈13,216.74M = 2,000,000 \times \frac{0.004583(1 + 0.004583)^{240}}{(1 + 0.004583)^{240} – 1} \approx 13,216.74M=2,000,000×(1+0.004583)240−10.004583(1+0.004583)240​≈13,216.74

Your estimated monthly mortgage payment would be approximately $13,216.74.
