APY already includes the effect of compounding, so the maturity value is your deposit grown at that yield for the term. Early withdrawal from a CD usually means a penalty, so plan to leave the money in place.

Frequently Asked Questions

What is a CD?

A certificate of deposit is a savings product where you lock money away for a fixed term at a fixed rate, usually earning more than a regular savings account.

How is the maturity value calculated?

APY already reflects compounding, so the tool grows your deposit at that yield for the length of the term to give the value at maturity.

What is the difference between APY and APR?

APR is the simple annual rate, while APY includes the effect of compounding. Banks advertise CDs by APY, which is what this tool uses.

Can I take the money out early?

Usually only with a penalty, often several months of interest. Plan to leave the money until the term ends.

Are CDs a good place for savings?

They suit money you will not need for a set period and want to keep safe with a guaranteed return. For money you might need sooner, a high-yield savings account is more flexible.

Is my data private?

Yes. The calculation runs entirely in your browser.
