Frequently Asked Questions
Clear explanations of compounding frequency, FDIC safety, and interest taxation.
How much interest does a $10,000 CD earn at 4.8% APY in 1 year?
A $10,000 1-year Certificate of Deposit paying 4.8% APY will generate exactly $480 in guaranteed interest at maturity, resulting in a final payout of $10,480.
What happens if I withdraw my money from a CD early?
If you withdraw funds from a CD before the maturity date, the bank will impose an early withdrawal penalty. For a 12-month CD, the typical penalty is 90 to 180 days of interest, which reduces your total profit.
Can you add money to a Certificate of Deposit after opening?
Most standard CDs do not allow ongoing deposits after the initial funding. You invest a lump sum at the start. If you want to make recurring monthly deposits, an HYSA or an "add-on CD" is a better option.
