How to Use the Commercial Real Estate Mortgage Calculator
Using the calculator is simple. You only need to input a few details, and it will instantly provide your estimated mortgage payment. Here’s a step-by-step guide:
- Enter the Loan Amount – The total amount you plan to borrow for the commercial property.
- Input the Interest Rate – The annual interest rate offered by your lender (e.g., 6.5%).
- Set the Loan Term – The duration over which you’ll repay the loan (in years).
- Add Down Payment (if applicable) – This reduces your loan amount and overall interest.
- Click Calculate – The tool will show your monthly payment, total payment, and total interest.
Formula Used in the Calculator
The calculator uses the standard mortgage amortization formula:
Monthly Payment (M) = 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 (loan term × 12)
Example Calculation
Example 1:
- Loan Amount: $1,000,000
- Interest Rate: 6% per year
- Loan Term: 20 years
Step 1: Convert interest rate to monthly → 6% ÷ 12 = 0.005
Step 2: Total payments → 20 × 12 = 240 months
Step 3: Apply formula:
M = 1,000,000 × [ 0.005 × (1 + 0.005)^240 ] ÷ [ (1 + 0.005)^240 – 1 ]
M ≈ $7,164.31 per month
Total Payment = $7,164.31 × 240 = $1,719,434.40
Total Interest = $1,719,434.40 – $1,000,000 = $719,434.40
