Browser-based
Enter your current loan balance, rate, and remaining term, then compare monthly payment, total interest, and optional closing-cost break-even with a refinanced loan.
How to use this tool
1. Enter current loan balance, rate, and remaining term. 2. Enter the new rate, new term, and optional closing costs. 3. Compare monthly payment, interest savings, and break-even months.
Worked example
Example: $250,000 remaining at 7% with 25 years left vs a 5.5% refinance over 25 years with $3,000 closing costs—see monthly savings and how many months until fees are recovered.
How it works
Compares your current mortgage payment and total interest with a refinanced loan using standard amortization formulas. Closing-cost break-even is estimated when you enter refinance fees.
