Here's how much interest a $10,000 18-month CD will earn savers who act now

An 18‑month CD locking funds until Jan 2028 now pays about 4.15%–4.20%—a $10,000 deposit would earn roughly $622–$637 by maturity.
A top high‑yield savings account pays around 4.10% (≈$622 on $10k over 18 months) and keeps your money accessible, but the rate can change.
Decide based on whether you value certainty or liquidity—many savers split funds or simply move money out of traditional savings (under 1% rates).
