Practical Examples of Using the Calculator
Example 1: Lower Interest Rate Savings
Imagine you have:
- Loan balance: $250,000
- Current interest rate: 6.5%
- New interest rate: 5.2%
- Loan term: 30 years
- Closing cost: $3,000
After entering this data, the calculator shows:
- Current monthly payment: ~$1,580
- New monthly payment: ~$1,380
- Monthly savings: ~$200
- Break-even point: ~15 months
- Yearly savings after costs: significant positive value
👉 In this case, refinancing is a smart choice if you plan to stay in the home longer than 1–2 years.
Example 2: High Closing Cost Scenario
Now consider:
- Loan balance: $180,000
- Current rate: 5.8%
- New rate: 5.5%
- Closing cost: $6,000
Results may show:
- Small monthly savings (around $40–$60)
- Break-even point: over 8–10 years
👉 In this case, refinancing may not be beneficial unless long-term savings outweigh upfront costs.
