Practical Example: Refinancing Scenario

Let’s say Sarah has a $200,000 mortgage at 6.5% interest with 25 years left to pay. She’s considering refinancing at 5.25% for a new 30-year term, with $3,500 in closing costs. She plans to stay in her home for another 7 years.

After entering these values and hitting Calculate, the tool provides the following estimates:

• Current Payment: $1,350
• New Payment: $1,107
• Monthly Savings: $243
• Break-even Time: 14 months
• Total Interest Saved: $21,700
• Total Cost of New Loan: $92,000 (for the duration she stays)

In Sarah’s case, refinancing makes sense—she recovers her closing costs in just over a year and enjoys thousands in savings over time.
