CD Calculator
CD Calculator
How it works: This calculator calculates the growth of a Certificate of Deposit (CD) using compound interest. The formula is: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years. APY (Annual Percentage Yield) shows the effective annual rate including compounding effects.

FAQ
What's the difference between interest rate and APY?
Interest rate is the nominal rate. APY (Annual Percentage Yield) includes the effect of compounding and shows the effective annual rate.
How does compounding frequency affect CD returns?
More frequent compounding (daily vs monthly) yields slightly higher returns. The difference is small but increases with higher rates and longer terms.
Are CDs better than regular savings accounts?
CDs typically offer higher interest rates than savings accounts but lock your money for the term. Consider your liquidity needs before choosing.
What happens if I withdraw early from a CD?
Early withdrawal usually results in a penalty, typically several months of interest. Check the specific terms before opening a CD.
Should I build a CD ladder?
A CD ladder involves buying CDs with staggered maturity dates. This provides regular access to cash while taking advantage of higher rates on longer terms.
