Frequently Asked Questions

Everything you need to know.

Are CDs worth it in 2026?

With 1-year CD rates around 4.15%, CDs offer competitive guaranteed returns. They make sense for money you will not need for the term. For money you might need, a HYSA at 4.40% with full liquidity is often the better choice.

What is the early withdrawal penalty for a CD?

Penalties vary by institution and term. Typical penalties: 6-month CD = 3 months interest; 1-year CD = 6 months interest; 2-year CD = 12 months interest. Some institutions offer no-penalty CDs — worth comparing if you may need the money early.
