Frequently Asked Questions about Refinance Calculator
When does refinancing make financial sense?
Refinancing is typically worthwhile if you can lower your interest rate by at least 0.75% to 1.0% and plan to stay in the home longer than the break-even period.
What fees are included in closing costs?
Closing costs typically range from 2% to 5% of loan principal, including appraisal, loan origination, title search, insurance, and recording fees.
What is a no-closing-cost refinance?
In a no-closing-cost refinance, the lender covers upfront fees in exchange for a slightly higher interest rate or by rolling the costs into your principal balance.
Does refinancing hurt your credit score?
Applying for a refinance causes a small, temporary dip (usually 5 to 10 points) due to hard credit inquiries, but your score rebounds quickly with on-time payments.
