Example Calculation

Let’s walk through an example to illustrate how the calculator works:

Loan Amount: $300,000
Annual Interest Rate: 4%
Loan Term: 30 years
Extra Monthly Payment: $200

Step 1: Standard Monthly Payment
The regular monthly payment without extra contributions is calculated using the mortgage formula:
≈ $1,432.25

Step 2: Impact of Extra Payment
Adding $200 per month toward the principal will:

Reduce total interest paid by approximately $50,000
Shorten the loan term from 30 years to around 25.3 years

This demonstrates how even a small extra monthly payment can have a significant impact over time.
