Frequently Asked Questions

How is CD growth calculated?

APY (annual percentage yield) already accounts for how often interest compounds, so the math is simply your deposit compounded annually at the APY over the term: Total = Deposit × (1 + APY)^years.

Is my rate guaranteed for the whole term?

For a standard fixed-rate CD, yes — the APY you lock in at opening applies for the full term, unlike a savings account rate which can change at any time.

What happens if I withdraw early?

Most CDs charge an early withdrawal penalty, often a number of months' interest, which isn't factored into this calculator. Check your CD's terms before committing funds you might need early.

Is this financial advice?

No — this is an estimate for planning purposes only, not financial advice. Confirm exact terms with your bank or credit union.
