Example Calculation

To see how it works, consider this scenario:

House Price: $400,000
Down Payment Percentage: 20%
Loan Term: 30 years
Interest Rate: 6%

Step 1: Calculate Down Payment
Down Payment = House Price × (Down Payment % / 100)
= 400,000 × 0.20
= $80,000

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

Step 3: Calculate Monthly Payment
Monthly Rate = 6% / 12 = 0.005
Total Months = 30 × 12 = 360
Monthly Payment = (Loan Amount × Monthly Rate) / (1 − (1 + Monthly Rate)^−Total Months)
= (320,000 × 0.005) / (1 − (1 + 0.005)^−360)
≈ $1,918.56

This calculation shows that with a $80,000 down payment, your loan amount will be $320,000, and your monthly mortgage payment will be approximately $1,918.56.
