Many borrowers who purchased homes between 2023 and 2025 could still save money by refinancing, even with current rates above 6.5%. At a 6.37% rate, 32.5% of recent borrowers might benefit, with average annual savings of $2,320. Savings improve if rates drop to 6%. Refinancing costs must be weighed against monthly savings, typically requiring about a half-point rate drop to be worthwhile. Geographic differences affect potential savings.
