Frequently Asked Questions
What is a CD?+
A certificate of deposit is a time-locked savings product with fixed rate for a defined term.
What is APY?+
APY includes compounding effects and reflects effective annual yield.
Can I withdraw early?+
Early withdrawal usually triggers penalties that reduce net return.
How does term length affect earnings?+
Longer terms can increase earnings but reduce liquidity.
Are CDs safe?+
Bank-issued CDs are generally low-risk and may be insured within coverage limits.
Can I ladder CDs?+
Yes. CD ladders balance liquidity and yield by staggering maturities.
Should tax be considered?+
Yes. Tax on earned interest can reduce net effective return.
How often should CD rates be compared?+
