How this calculator works
- APY already includes compounding, so maturity value = deposit × (1 + APY)^years. Interest is taxable as ordinary income in the year it's credited, even if you don't withdraw it.
Frequently asked questions
What happens if I withdraw early?
Most CDs charge a penalty of 3–12 months of interest for early withdrawal. No-penalty CDs exist at slightly lower rates.
Are CDs FDIC insured?
Yes — up to $250,000 per depositor, per bank, per ownership category. Spreading large sums across banks preserves full coverage.
What's a CD ladder?
Splitting money across staggered terms (e.g. 1/2/3/4/5-year CDs) so a portion matures every year — you capture long-term rates while keeping regular liquidity.
