Refinance Calculator
🇺🇸 US-specific: mortgage refinance mechanics (closing costs, break-even analysis) follow the US home-loan system.
Enter a positive balance, non-negative rates, and positive terms.
Your new payment is higher than your current one — refinancing at these terms wouldn't lower your monthly cost.
Free refinance calculator that shows your break-even point in months — not just the monthly savings competitors stop at — so you know exactly when a refinance actually pays off.
How it works
- Enter your current loan balance, rate, and months remaining
- Enter the new rate, term, and closing costs
- See your monthly savings and exactly how many months until the closing costs are recouped
Frequently asked questions
What is the break-even point?
It's how many months of monthly savings it takes to recoup what you paid in closing costs. If you plan to stay in the home past that point, the refinance pays off; if you'll move or refinance again sooner, it may not.
Why would my new payment be higher even at a lower rate?
If you reset the clock to a full new 30-year term after already paying down years on your current loan, the lower rate can still be offset by starting over. This tool compares your actual remaining months, not a fresh assumption.
