🏦 CD vs High‑Yield Savings

🔒 CD	Fixed rate / lock‑in / penalty for early withdrawal
🏦 HYSA	Variable rate / instant access / current ~3.8-4.3%
📜 T‑Bills	Short‑term, state tax exempt, very low risk

💡 If rate cuts expected, lock longer CDs.

📘 What is a CD Calculator & How to Maximize Your Deposit?

A Certificate of Deposit (CD) offers a fixed interest rate for a specific term, usually higher than regular savings. Early withdrawal incurs a penalty. This tool helps you compute maturity earnings, set up a CD ladder, adjust for inflation, and see the impact of Federal Reserve rate changes.

🔍 How is CD interest calculated?

Using the compound interest formula: A = P × (1 + r/n)^(n×t). Monthly compounding typically yields higher returns than annual.

⚖️ CD vs High‑Yield Savings Account

CDs lock your rate; HYSAs are flexible. If you expect falling rates, locking a CD is advantageous; if rates might rise, a ladder or HYSA gives flexibility.

📅 Is now a good time to lock a long‑term CD?

With the Fed expected to cut rates in 2026, current 4%+ APY offers a rare opportunity. If you can lock funds for 2‑5 years, consider longer CDs. Otherwise, use a CD ladder.
