About This Calculator
The CD (Certificate of Deposit) Calculator helps you determine how much your CD investment will be worth at maturity and how much interest you'll earn. CDs are low-risk savings instruments offered by banks with fixed interest rates and terms.
This calculator accounts for different compounding frequencies (daily, monthly, quarterly, etc.) to provide accurate maturity value calculations. Compare different CD terms and rates to find the best option for your savings goals.
Formula & Calculation Method
CD Maturity Value Formula:
Maturity Value = Principal × (1 + r/n)^(n×t)
Interest Earned = Maturity Value - Principal
Where:
r = Annual interest rate (as decimal)
n = Compounding frequency per year
t = Time period in years
More frequent compounding (daily vs. annually) results in slightly higher returns due to compound interest working more often. This calculator supports daily, monthly, quarterly, semi-annual, and annual compounding.

Frequently Asked Questions
What is a CD (Certificate of Deposit)?
A CD is a time deposit offered by banks with a fixed interest rate and maturity date. You deposit money for a specific term and earn interest. CDs typically offer higher rates than savings accounts but require you to keep the money invested until maturity.
What happens if I withdraw early?
Early withdrawal from a CD typically results in a penalty fee, which reduces your earnings. This calculator shows the value at maturity; early withdrawal would be less after penalties.
How does compounding frequency affect returns?
More frequent compounding (daily vs. annually) results in slightly higher returns because interest earns interest more often. The difference is usually small but compounds over longer terms.
Are CD earnings taxable?
Yes, CD interest is taxable as ordinary income in the year it's earned. Some CDs, like those in IRAs, may have different tax treatment.
