Refinancing can save you thousands of dollars, or it can cost you money if done wrong. It all depends on your "Break-Even Point".

The 1% Rule of Thumb

Historically, experts said you should only refinance if you can lower your interest rate by at least 1%. However, with closing costs rising, you need to do the math.

Calculating Your Break-Even Point

Refinancing isn't free. Closing costs typically run 2% to 5% of the loan amount. To find your break-even point:

Total Closing Costs ÷ Monthly Savings = Months to Break Even

Example: If closing costs are $4,000 and you save $200/month, it will take 20 months to break even. If you plan to move in 12 months, don't refinance.

Reasons to Refinance

  • Lower Monthly Payment: Improve cash flow.
  • Shorten Term: Switch from 30-year to 15-year to pay off the home faster.
  • Cash-Out: Tap into your home equity for renovations (Use our BRRRR calculator for investors).
  • Remove PMI: If your home value has increased, refinancing might eliminate mortgage insurance.
