Example Calculation

Let’s walk through an example:

Property Price: $400,000
Down Payment Percentage: 20%
Interest Rate: 5% per year
Loan Term: 30 years

Step 1: Calculate Down Payment
Down Payment = Property Price × (Down Payment Percentage ÷ 100)
= 400,000 × 0.20 = $80,000

Step 2: Calculate Loan Amount
Loan Amount = Property Price − Down Payment
= 400,000 − 80,000 = $320,000

Step 3: Calculate Monthly Payment
Monthly Interest Rate = 5% ÷ 12 = 0.004167
Total Months = 30 × 12 = 360
Monthly Payment = (Loan Amount × Monthly Rate) ÷ (1 − (1 + Monthly Rate)^−Total Months)
= (320,000 × 0.004167) ÷ (1 − (1 + 0.004167)^−360) ≈ $1,718.63

So, using the calculator, you would need $80,000 as a down payment, borrow $320,000, and pay approximately $1,718.63 monthly.
