Refinances come in two main forms, and they do very different things to your loan balance:
Rate-and-term. The new loan pays off the old one for roughly the same amount you still owe, then continues on new terms. A borrower might move from a 30-year to a 15-year term, or from one rate to another. Because no equity is withdrawn, the amount owed doesn’t jump — the goal is to reshape the loan, not to extract money.
Cash-out. Suppose you owe less than your home is worth — that gap is your equity. In a cash-out refinance, the new loan is written for more than your current payoff, the old loan is cleared, and the extra amount is paid to you in cash. That cash comes at a cost: your total balance is now larger, and you’ll typically pay interest on it over a fresh loan term. Lenders limit how much you can take out, usually leaving a cushion of equity in the home.
Both types carry closing costs (commonly ~2–5% of the loan amount) and both fully replace your existing mortgage, including its rate.

Trade-offs to weigh
The CFPB notes that cash-out refinancing turns home equity into debt secured by the home, and encourages comparing it against other ways of borrowing before deciding.
The distinction is simple to state: rate-and-term reshapes the loan you have, while cash-out enlarges it to pull equity out as cash. To reason between them, start from your goal. If the goal is a different rate or term, rate-and-term is the relevant tool — and its worth turns on break-even math. If the goal is accessing equity, weigh a cash-out refinance against tapping equity while leaving your first mortgage untouched — through a HELOC or second mortgage — and compare the full cost of each. Neither is inherently better; the right frame is which one matches your goal at the lowest total cost.
