📈 Compounding and APY explained
Compounding frequency determines how often earned interest is added to the principal. More frequent compounding (e.g., daily) yields slightly higher returns than annual compounding for the same nominal rate. APY—annual percentage yield—shows the effective annual return accounting for compounding.
✅ Tips for maximizing CD returns
- Shop around for the best APY
- Consider laddering multiple CDs with staggered maturities
- Match CD term to your liquidity needs
- Check penalties for early withdrawal
