How CD earnings are calculated
final balance = deposit × (1 + APY)years
Because the calculator takes APY (annual percentage yield), compounding is already baked in — no need to know whether the bank compounds daily or monthly. A $10,000 CD at 4.00% APY for 2 years: 10,000 × 1.04² = $10,816, or $816 in interest.
If a bank quotes an interest rate instead of APY, the APY is slightly higher once compounding is included — here's the difference. Two caveats the math ignores: early-withdrawal penalties (typically 3–12 months of interest) and taxes (CD interest is ordinary income). Details in the FAQ below.
CD calculator FAQ
- How are CD earnings calculated?
- CD earnings use compound interest: final balance = deposit × (1 + APY)^(years). Because a CD's rate is fixed for the whole term, you can calculate your exact payout the day you open it — that certainty is the main appeal of a CD over a savings account.
- What's the difference between CD yield (APY) and the interest rate?
- APY includes compounding; the plain interest rate doesn't. A 5.00% rate compounded monthly is about a 5.12% APY. Always enter and compare APY — it's the number that determines what you actually earn.
- Do CD calculators account for early-withdrawal penalties?
- No — this calculator assumes you hold to maturity. Breaking a CD early typically costs 3–12 months of interest, which can erase your earnings entirely. Only commit money you won't need before the term ends.
- Are CD earnings taxable?
- Yes — CD interest is taxed as ordinary income in the year it's credited, even if you don't withdraw it. The bank sends a 1099-INT for interest over $10. (CDs held inside an IRA follow that account's tax rules instead.)
