Early Penalty = Principal × (APR/12) × Penalty Months

CDs offer higher rates than regular savings accounts in exchange for locking up your money for a fixed term. Early withdrawal penalties typically range from 3–12 months of interest. CD laddering — splitting deposits across multiple terms (3mo, 6mo, 1yr, 2yr, 5yr) — provides both higher rates and regular liquidity windows. Always compare CD APY to the best HYSA rates before locking in.
