When to refinance

Refinancing replaces your current loan with a new one, ideally at better terms. It makes sense when the savings outweigh the costs.

Rule of thumb

Refinancing often makes sense if you can lower your rate by at least 1%, and you plan to keep the loan long enough to pass the break-even point.

Refinance checklist

  • Lower rate available? — Compare offers from multiple lenders
  • Closing costs reasonable? — Factor in all fees
  • Break-even timeline? — Will you keep the loan long enough?
  • Term considerations? — Longer term = lower payment but more interest

Common refinancing scenarios

  • Auto loans — Rates drop or your credit improves
  • Student loans — Federal to private (be cautious), or rate reduction
  • Personal loans — Credit score improvement unlocks better rates
  • Mortgages — Rate drops significantly (usually 0.5-1%+)
