Estimate for a US mortgage. Extending the term can lower the payment but add interest overall — check the total-savings card before deciding.
How it works
Savings = old payment − new payment. Break-even = closing costs ÷ monthly savings. Interest saved = old total interest − new total interest.
Example: refinancing $250,000 from 7% to 5.5% over 30 years → saves ~$244/month, break-even ≈ 17 months at $4,200 closing costs.

Frequently Asked Questions
How do I know if refinancing is worth it?
Compare your current monthly payment and total interest against the new loan's. This calculator shows the monthly savings, the break-even point and total interest saved, so you can decide if the closing costs are justified.
What is the break-even point in refinancing?
It is the number of months for your monthly savings to cover the refinance closing costs. If you plan to stay in the home past that point, the refinance generally pays off.
Should I refinance to a lower rate or a shorter term?
A lower rate cuts your payment; a shorter term (for example 30 to 15 years) builds equity faster and saves far more interest, though your monthly payment may rise. Enter both scenarios to compare.
Does refinancing affect my credit score?
Lenders run a hard credit inquiry and your old loan closes while a new one opens, which can cause a small, temporary score dip. Most people's scores recover within a few months of on-time payments.
