Example: Comparing Two Mortgage Scenarios
Imagine you’re buying a home with these details:
- Home Price: $350,000
- Down Payment: $50,000
- Loan Amount: $300,000
Scenario 1: 30-Year Loan at 6.5%
- Monthly Payment: ~$1,896
- Total Interest Paid: ~$382,000
- Total Loan Cost: ~$682,000
Scenario 2: 15-Year Loan at 6.0%
- Monthly Payment: ~$2,531
- Total Interest Paid: ~$156,000
- Total Loan Cost: ~$456,000
Result: By choosing a 15-year loan, you pay ~$635 more per month but save $226,000 in interest over the life of the loan.
