A Lower Rate Does Not Always Mean Lower Total Cost
Refinancing replaces an existing mortgage with a new loan. A lower rate or monthly payment can be attractive, but extending the repayment period or financing closing costs can change the long-term result.
The strongest refinance comparison considers both near-term cash flow and the total cost of carrying the new mortgage for as long as you expect to keep it.

Frequently Asked Questions
When does refinancing a mortgage make sense?
Refinancing may make sense when the expected financial benefit of the new loan outweighs closing costs and other tradeoffs and aligns with how long you expect to keep the mortgage.
What is a refinance break-even point?
The refinance break-even point estimates how long monthly savings may take to recover the closing costs and upfront expenses associated with the new loan.
Does refinancing restart a mortgage?
A refinance replaces the existing mortgage with a new loan and new repayment schedule. Choosing another long term may extend the total time you remain in debt.
What is cash-out refinancing?
A cash-out refinance generally replaces the existing mortgage with a larger loan and provides part of the difference to the borrower in cash, subject to qualification and available equity.
Is a lower mortgage rate always worth refinancing for?
Not necessarily. Closing costs, loan term, remaining balance, planned time in the home and total future interest should also be considered.
What is the difference between refinancing and recasting?
Refinancing replaces the existing mortgage with a new loan. Recasting generally keeps the existing mortgage but recalculates the payment after a substantial principal reduction, when the lender permits it.
Which refinance calculator should I use first?
Start with a general Mortgage Refinance Calculator to compare the existing and proposed loans. Then evaluate the break-even point and amortization schedule before deciding whether the refinance supports your goals.
