Business Mortgage Calculator
Buying property for business purposes is a major financial decision. Whether you’re purchasing an office, retail space, warehouse, or rental property, it’s crucial to understand the financial implications. A Business Mortgage Calculator helps investors and business owners estimate loan payments, total debt service, and even net cash flow when rental income is factored in.
This tool is designed to give a clear picture of borrowing costs and profitability before committing to a commercial real estate purchase.
Formula
- Loan Amount = Purchase Price – Down Payment
- Monthly Payment = [Loan Amount × Monthly Interest Rate] ÷ [1 – (1 + Monthly Interest Rate)^–Number of Months]
- Annual Debt Service = Monthly Payment × 12
- Net Annual Cash Flow = (Rental Income × 12) – Annual Debt Service
How to Use the Business Mortgage Calculator
- Enter the property purchase price.
- Input your down payment.
- Enter the annual interest rate offered by the lender.
- Specify the loan term in years.
- (Optional) Input expected monthly rental income if the property generates revenue.
- Click Calculate to see loan amount, payments, and potential cash flow.
Example
Imagine you want to purchase a commercial property worth $600,000 with a $120,000 down payment. You secure a loan at 6% interest for 20 years.
- Loan Amount = $600,000 – $120,000 = $480,000
- Monthly Payment ≈ $3,441
- Annual Debt Service = $3,441 × 12 = $41,292
If the property generates $5,000 monthly rental income:
- Annual Income = $60,000
- Net Annual Cash Flow = $60,000 – $41,292 = $18,708
This shows the investment can produce positive annual cash flow.
