Calculate exactly how much interest a CD earns over any term, and compare different CD rates side by side.

Quick answer: CD yield is the guaranteed interest earned over a fixed term at a stated APY. Compare CDs by APY, term, early-withdrawal penalty, and whether you need access before maturity.

The Safe-Money Playbook: Match Cash to Its Timeline (2026)Safe money is not one product, it is a spectrum, and the mistake is putting all your cash in one place. The right vehicle depends on when you will need the money and, just as importantly, how it is taxed. This playbook sorts your savings into timeline buckets, shows why a lower-rate Treasury can beat a higher-rate CD after tax, and explains the laddering move that protects you when rates fall.

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.
