5. Frequently Asked Questions (FAQ)

Q1: What is the advantage of monthly compounding?
A: Monthly compounding allows your investment to grow faster than annual compounding because interest is added to the principal more frequently, creating a snowball effect.

Q2: How does CD interest compare to regular savings accounts?
A: CDs typically offer higher interest rates than regular savings accounts but require you to lock in your money for a specific term.

Q3: Are there penalties for early withdrawal from CDs?
A: Yes, most CDs charge early withdrawal penalties, which can significantly reduce your earned interest if you access the funds before maturity.

Q4: Can I add more money to a CD after opening it?

Q5: Are CD interest rates fixed or variable?
A: Most CDs offer fixed interest rates for the entire term, though some financial institutions may offer variable-rate CDs.
