Results are calculated using the APY you entered for each CD. APY already reflects the effect of your institution's compounding method, providing a direct apples-to-apples comparison between both CDs. These are hypothetical values — not rates quoted, guaranteed, or committed to by any financial institution. Enter the APY quoted to you by your institution for the most accurate estimate.
Calculation Method Ending Balance = Principal × (1 + APY)Term÷12  —  APY is applied as an annualized rate over the fractional year represented by the term entered. No intra-period compounding is assumed; the APY already captures your institution's compounding method. Assumes a standard fixed-rate CD held to maturity.

⚠ Important: The prorated estimate above uses APY only and does not represent an early withdrawal value. Actual proceeds from early CD withdrawal are subject to your institution's penalty terms and could result in reduced earnings or loss of principal. This estimate assumes a standard fixed-rate CD and may not apply to variable-rate, step-rate, bump-up, or add-on CD products.

Rates & Results Rates are entered manually and do not reflect currently offered, guaranteed, or locked rates. Rates and terms are subject to change without notice. Results assume a single standard fixed-rate CD term with no reinvestment, rollover, or automatic renewal. A 12-month CD renewed at maturity is not equivalent to a single longer-term CD and may earn a different rate.
Important Disclosures
For Illustrative Purposes Only This calculator provides estimates only and does not constitute a deposit commitment, contract, or official rate quote. Results are not guaranteed. Please contact a branch representative for official CD rates, terms, and Truth in Savings disclosures.
Deposit Product — Not a Loan or Lending Offer This calculator relates solely to certificate of deposit (CD) products, which are deposit instruments. It does not constitute, imply, or advertise any offer to lend, extend credit, or enter into any lending arrangement. No commitment to accept deposits is expressed or implied. CD deposits are subject to your institution's account agreements and applicable law.
Annual Percentage Yield (APY) — Regulation DD & TISA APY (Annual Percentage Yield) is a standardized measure of the total interest earned on a deposit account over one year, expressed as a percentage, as defined under the Truth in Savings Act (TISA) and Regulation DD (12 CFR Part 1030). APY accounts for the effect of the institution's compounding method, enabling a direct comparison regardless of compounding frequency. Rates entered in this calculator are hypothetical and have not been verified or quoted by any institution. Always use the APY quoted by your institution.
Standard Fixed-Rate CD Assumption All calculations in this tool assume a standard fixed-rate certificate of deposit held to maturity. Results may not apply to variable-rate, step-rate, bump-up, add-on, or other specialty CD products. Contact your institution for terms specific to the CD product you are considering.
Early Withdrawal CDs are intended to be held to maturity. Early withdrawal penalties vary by institution and CD agreement and could result in reduced earnings or loss of principal. The prorated interest figures shown in this calculator use APY only and do not represent actual early withdrawal proceeds. Contact your institution for specific penalty terms before opening or withdrawing from a CD.
Taxes Interest earned on CDs is generally subject to federal income tax in the year it is credited or constructively received, regardless of whether funds are withdrawn. Interest may be reported to you on Form 1099-INT. State and local income taxes may also apply and vary by jurisdiction. This calculator does not account for any tax obligations. Consult a qualified tax advisor for guidance specific to your situation.
No Solicitation This calculator is provided for educational and illustrative purposes only and does not constitute a solicitation, advertisement, or offer to open a deposit account or purchase any financial product. No commitment to lend, invest, or accept deposits is expressed or implied.
FDIC Insurance FDIC deposit insurance covers up to the current standard maximum deposit insurance amount (SMDIA) per depositor, per ownership category, per insured institution. Balances exceeding applicable limits are not insured. If the principal entered approaches or exceeds the SMDIA, an inline notice will appear above the input field. Visit FDIC.gov for current coverage limits and ownership category details.
