- See the maturity value. Read the value at maturity and the interest earned.
CDs vs high-yield savings
A CD trades liquidity for a locked, fixed rate — useful when you won’t need the money before maturity and want certainty. If you need access, a high-yield savings account keeps the money liquid at a variable rate. The APY calculator helps compare quotes on an equal footing.
Educational tool only — not financial advice. Assumes the CD is held to maturity; interest is generally taxable. Figures are estimates.
Frequently asked questions
- A certificate of deposit (CD) pays a fixed APY for a fixed term. This calculator compounds your deposit at that APY over the term and shows the maturity value and the interest earned.
- Enter the CD’s term in months (e.g. 12 for a 1-year CD). The APY is the rate the bank advertises; it already accounts for compounding.
- Most CDs are a single lump-sum deposit with no additions until maturity, which is what this models. For recurring deposits use the savings or high-yield savings calculator.
- Withdrawing before maturity usually forfeits some interest as a penalty; this tool shows the value if held to maturity.
- No — it computes in your browser.
