Commercial Mortgage Calculator

Purchasing or refinancing a commercial property is a significant financial step, whether you’re a small business owner, a property investor, or a corporation.

Why Use a Commercial Mortgage Calculator?

Commercial property financing often involves:

  • Higher loan amounts
  • Different interest rate structures (fixed or variable)
  • Shorter loan terms compared to residential mortgages
  • Balloon payments in some cases

A Commercial Mortgage Calculator helps you:

  • Estimate monthly repayments
  • Compare loan scenarios
  • Plan cash flow
  • Understand the total interest payable
  • Assess affordability before approaching lenders

How to Use the Commercial Mortgage Calculator

Using the calculator is straightforward. You’ll typically enter:

  1. Loan Amount – The total amount you wish to borrow.
  2. Interest Rate (%) – The annual interest rate offered by the lender.
  3. Loan Term (Years) – The duration over which you plan to repay the loan.
  4. Payment Frequency – Usually monthly, but can be quarterly or annually.

Steps:

  1. Input your desired loan amount.
  2. Enter the interest rate your lender is offering or you expect to receive.
  3. Select your repayment term (e.g., 10, 15, 20 years).
  4. Click Calculate to instantly see:
    • Monthly payment amount
    • Total repayment over the term
    • Total interest paid

Formula Used

The formula for calculating monthly repayments is based on the standard loan amortization equation:

Monthly Payment = [P × r × (1 + r)ⁿ] ÷ [(1 + r)ⁿ – 1]

Where:

  • P = Loan principal (amount borrowed)
  • r = Monthly interest rate (annual rate ÷ 12)
  • n = Total number of payments (months in the loan term)

This formula ensures each payment is the same while covering both principal and interest portions.

Example Calculation

Scenario:

  • Loan Amount: $500,000
  • Interest Rate: 6% per year
  • Term: 15 years

Step 1: Convert interest rate to monthly: 6% ÷ 12 = 0.5% (0.005 in decimal).
Step 2: Total months = 15 × 12 = 180 months.
Step 3: Apply the formula:

Monthly Payment = [500,000 × 0.005 × (1 + 0.005)¹⁸⁰] ÷ [(1 + 0.005)¹⁸⁰ – 1]
Monthly Payment ≈ $4,219.28

Results:

  • Monthly Payment: $4,219.28
  • Total Repayment: $759,470.40
  • Total Interest: $259,470.40

Factors That Affect Your Commercial Mortgage
