Calculate the maturity value of your Certificate of Deposit, total interest earned, and effective APY. Compare different CD terms, interest rates, and compounding frequencies to maximize your savings returns.
A Certificate of Deposit (CD) is a time deposit offered by banks and credit unions that typically offers higher interest rates than regular savings accounts in exchange for locking your money for a fixed term. Early withdrawal penalties apply if you withdraw before maturity.
Example: $10,000 CD at 5.25% APY compounded monthly for 5 years
Monthly rate = 0.0525 ÷ 12 = 0.004375
Number of periods = 12 × 5 = 60
Future Value = $10,000 × (1.004375)60 = $12,989.19
Total Interest = $2,989.19
| Term | Maturity Value | Total Interest | Effective APY |
|---|---|---|---|
| 6 months | $10,259.12 | $259.12 | 5.31% |
| 1 year | $10,537.54 | $537.54 | 5.38% |
| 2 years | $11,104.82 | $1,104.82 | 5.38% |
| 3 years | $11,703.52 | $1,703.52 | 5.38% |
| 5 years | $12,989.19 | $2,989.19 | 5.38% |
❓ What is APY vs Interest Rate?
APY (Annual Percentage Yield) includes the effect of compounding, while the stated interest rate does not. The more frequent the compounding, the higher the APY. For the same stated rate, daily compounding gives the highest return.
❓ Are CDs FDIC insured?
Yes, CDs from FDIC-member banks are insured up to $250,000 per depositor, per bank. Credit union CDs are NCUA insured with the same limit.
❓ What happens when a CD matures?
At maturity, you typically have a grace period (7-10 days) to withdraw or renew. If you don't act, most banks automatically renew at current rates.
❓ What are early withdrawal penalties?
Most CDs charge penalties for early withdrawal, typically 3-12 months of interest. Our calculator helps you compare penalty vs potential returns.
❓ CD Laddering Strategy
CD laddering involves splitting your investment across multiple CDs with different maturity dates (e.g., 1, 2, 3, 4, 5 years). This provides liquidity while capturing higher long-term rates.
❓ Callable vs Non-Callable CDs
Callable CDs allow the bank to "call" (redeem) your CD before maturity, typically when interest rates drop. Non-callable CDs guarantee the rate for the full term.
❓ Brokered CDs vs Bank CDs
Brokered CDs are sold through brokerage firms and may offer higher rates but have different liquidity and early withdrawal rules. Traditional bank CDs are simpler and directly FDIC insured.
💡 Pro Tip: Use our calculator to compare CD rates from different banks. Even a 0.25% rate difference on a $10,000, 5-year CD can mean over $130 in additional interest. Always check the early withdrawal penalty terms before investing.
