How to use this calculator

  • Enter your current loan balance, rate, and years remaining.
  • Type the new rate you've been quoted and the new term.
  • Add the lender's estimated closing costs (often 2–5% of loan).
  • Check the break-even — only refinance if you'll stay past that point.

About this tool

Refinancing is a bet: you pay closing costs upfront in exchange for a lower monthly payment over the new loan's life. The two numbers that matter are the break-even month (how long until the monthly savings cover the closing fees) and the lifetime savings (does the deal still win once you account for the longer term you're probably extending into?). Rule of thumb: if you'll stay in the home longer than the break-even period and the lifetime savings are positive, refinance. If either fails, stick with the current loan.

Frequently asked

Lower payment, but you're extending the loan and likely paying more total interest. The lifetime-savings number above tells you the truth.
