Quick Answer

To calculate CD returns, use the compound interest formula: A = P(1 + r/n)^(nt), where P is principal, r is annual rate, n is compounding frequency, and t is years. Our free calculator at practicalwebtools.com instantly shows your maturity value and total interest earned.

Frequently Asked Questions

A Certificate of Deposit is a savings product where you deposit money for a fixed term at a fixed interest rate. CDs typically offer higher rates than regular savings accounts because you commit to leaving your money untouched until maturity. Early withdrawal usually incurs a penalty.
APR (Annual Percentage Rate) is the simple interest rate without compounding. APY (Annual Percentage Yield) includes the effect of compound interest and shows your actual return. A 5% APR compounded monthly has an APY of about 5.12%. Always compare APY when shopping for CDs.
More frequent compounding means higher returns. Daily compounding earns slightly more than monthly, which earns more than annually. For example, $10,000 at 5% for 1 year: daily compounding = $512.67 interest, annual = $500. The difference grows with larger amounts and longer terms.
Early withdrawal typically incurs a penalty, often 3-6 months of interest depending on the term. Some CDs have no-penalty options with slightly lower rates. Always check the early withdrawal penalty before opening a CD, especially for longer terms.
Yes, CD interest is taxable as ordinary income, even if you don't withdraw it. You'll receive a 1099-INT form for interest over $10. Consider tax-advantaged accounts (IRA CDs) or municipal bonds if you're in a high tax bracket.
A CD ladder involves buying multiple CDs with staggered maturity dates. For example, buy 5 CDs maturing in 1, 2, 3, 4, and 5 years. This provides regular access to funds while capturing higher long-term rates. As each CD matures, reinvest in a new 5-year CD.
