⚠️ Important Financial Notes:
• APY vs APR: Banks quote CDs by APY. If you enter a
nominal APR, this tool converts it to the true effective yield based
on your selected compounding frequency.
• FDIC Insurance: Standard coverage is
$250,000 per depositor, per institution. Amounts
above this are uninsured.
• Tax Treatment: CD interest is taxed as ordinary
income annually, even if reinvested. You'll owe taxes on accrued
interest each year.
• Early Withdrawal: Penalties vary widely by bank and
term length. This calculator assumes you hold to maturity.
