Refinancing

IntermediatePersonal Finance2 min read

Quick Definition

Replacing an existing loan with a new one, typically to obtain a lower interest rate, different term, or access equity.

Key Takeaways

  • The general rule is to refinance when you can reduce the rate by 0.75-1% or more
  • Calculate the break-even point: closing costs divided by monthly savings
  • Refinancing to a shorter term (30 to 15 years) builds equity faster despite higher payments
  • Cash-out refinancing converts home equity to cash but increases your loan balance

What Is Refinancing?

Refinancing is the process of replacing an existing loan with a new loan that has different terms, most commonly to secure a lower interest rate, reduce monthly payments, change the loan duration, switch from a variable to fixed rate, or access home equity through a cash-out refinance. The refinancing process involves a new application, appraisal, underwriting, and closing, with associated costs (typically 2-5% of the loan amount). The break-even point — the time required for monthly savings to offset closing costs — is a critical calculation for determining whether refinancing makes financial sense. Rate-and-term refinancing adjusts the loan terms, while cash-out refinancing converts equity into cash for other purposes.

Refinancing Example

  • 1Refinancing a $300,000 mortgage from 7.5% to 6.0% saves $318/month and $114,000 in total interest over 30 years.
  • 2With $4,500 in closing costs and $300/month savings, the break-even point is 15 months — refinancing makes sense if staying 2+ years.
  • 3A cash-out refinance on a $500,000 home with $200,000 remaining mortgage provides $100,000 cash (at 80% LTV) for home renovation.
