Practical Example: Estimating Mortgage Repayments

Suppose you want to buy a house and plan the following:

• Loan amount: $500,000
• Loan term: 30 years
• Interest rate: 6% per annum
• Repayment frequency: Monthly
• Extra repayment: $200 per month

Using the Commbank Mortgage Calculator:

• Standard monthly repayment: ~$2,997
• Total interest over 30 years without extra repayments: ~$579,000
• With $200 extra per month:
  • Repayment period reduces to ~26.5 years
  • Interest savings: ~$46,000

This example demonstrates how small extra repayments can significantly reduce both interest paid and loan duration.
