Certificate of deposit (CD) interest rates have fluctuated significantly over the past year, impacted by inflation and Federal Reserve rate adjustments. While high rates earlier allowed for lucrative returns, recent declines mean that a $10,000 CD now earns less than it did last spring. For instance, the interest on a 1-year CD was around 4.40% last year, yielding $440, but current rates are closer to 4.10%, earning about $410 over the same term. Despite this dip, rates remain competitive, and savers should consider locking in current rates to maximize returns before further declines. Alternatives like high-yield savings accounts, which also offer around 4%, provide flexibility with variable rates, but may fluctuate over time.
