Що таке CD (депозитний сертифікат)?

A certificate of deposit (CD) is a savings product offered by banks and credit unions with a fixed interest rate and a fixed term. You agree to leave your money deposited for the term length—from a few months to several years—in exchange for a typically higher rate than regular savings accounts. At maturity, you receive your initial deposit plus the accrued interest.

A = P × (1 + r/n)^(n×t)

P = principal, r = annual rate, n = compoundings per year, t = years

This calculator shows how much your CD will be worth at maturity, how much interest you earn, and how your balance grows over time. You can compare different term lengths and compounding frequencies.

Ключові поняття

APY (Annual Percentage Yield)

The annual rate of return including compound interest. APY is what banks typically advertise and is higher than the nominal rate when interest compounds more than once per year.

Compounding Frequency

How often interest is added to your balance—daily, monthly, quarterly, semi-annually, or annually. More frequent compounding generally means slightly higher effective returns.

термін

The length of time you commit to leave your money in the CD. Longer terms often offer higher APYs but your funds are locked until maturity (or you pay an early-withdrawal penalty).

  • CDs at FDIC-insured banks (USA) are protected up to $250,000 per depositor, per bank. This makes them one of the safest places to park cash.
  • For specific product details and rates, consult your bank or a financial advisor.

Tips

  • Compare CD terms: longer terms often have higher APYs but lock your money longer.
  • Daily compounding typically yields the highest effective return for a given APY.
  • Use the comparison table to see 3-month through 5-year terms at your chosen rate.

Compounding Reference
