At low-6% market rates in Early-Q2 2026, ~33% of recent 30-yr fixed borrowers could refinance and save ~$2.3K yearly before considering upfront costs.
If rates returned near ~6%, the share of recent 30-yr buyers who may benefit would reach ~57%, including ~60% of 2024 borrowers nationally.
Borrowers who purchased earlier show stronger upside: 2023 buyers could save ~$223 monthly, versus ~$191 for 2024 and ~$152 for 2025 buyers.
Refinancing costs usually run ~2% to ~6% of loan amount, so borrowers should compare fees, monthly savings, and planned ownership horizon first.
State savings vary widely: California averaged ~$363 monthly, Hawaii ~$355, while Iowa averaged ~$110, still meaningful room for broader household financial goals.
