CD Calculator
Calculate the maturity value and interest earned on a certificate of deposit (CD) based on your deposit, rate, and term.
Final balance at maturity
$10,460.25
What Your Result Means
The final balance is what your CD will be worth when it matures, combining your original deposit with all the compounded interest earned. CDs typically offer a fixed rate for the full term, so this projection is usually very accurate as long as you hold to maturity.
How It Is Calculated
Final Balance = Deposit × (1 + Rate/n)^(n × Years)
Worked Example
A $10,000 CD at 4.5% APY compounded daily for 12 months grows to approximately $10,460, earning about $460 in interest.
Important Assumptions
- Assumes the CD is held for the full term - early withdrawal typically incurs a penalty not modeled here.
- Uses the APY/rate as a constant for the full term, matching how most fixed-rate CDs work.
Frequently Asked Questions
- What happens if I withdraw early?
- Most CDs charge an early withdrawal penalty, often several months of interest. This calculator assumes you hold the CD to maturity.
