A Certificate of Deposit (CD) is a savings account that holds your money for a fixed period in exchange for a guaranteed interest rate. Unlike regular savings accounts where you can withdraw anytime, CDs require you to keep your money deposited until the maturity date to earn the full return.
Banks and credit unions offer CDs as a way to reward savers who commit their funds for a specific timeframe. The longer you agree to leave your money untouched, the higher the interest rate you typically receive. This makes CDs an attractive option for people who have money they won't need for months or years.
CD Quick Facts:
FDIC insured up to $250,000 per depositor
Terms typically range from 3 months to 5 years
Minimum deposits often start at $500-$1,000
Early withdrawal penalties apply before maturity
CDs gained popularity in the 1960s when the Federal Reserve allowed banks to offer them to consumers. Before this, only large institutional investors could access similar products. CDs provided everyday Americans with a safe way to earn higher returns than traditional savings accounts while supporting local banks.
Today, CDs remain one of the safest investment options available. Your principal is protected by FDIC insurance, and your return is guaranteed regardless of market conditions. This stability makes CDs particularly appealing during uncertain economic times.
Opening a CD involves depositing money for a predetermined term at a fixed interest rate. Your bank holds these funds, and in return, pays you interest throughout the term or at maturity, depending on how the CD compounds. When the term ends, you receive your original deposit plus all earned interest.
The key feature that distinguishes CDs from regular savings is the commitment period. You agree not to withdraw your funds before the maturity date. If you need access to your money early, you pay a penalty that typically equals several months of interest.
Choose Your Term and Deposit Amount
Select how long you can commit your funds and how much you want to deposit.
Lock In Your Interest Rate
The rate you see when you open the CD stays fixed for the entire term.
Earn Interest During the Term
Interest compounds daily, monthly, or quarterly depending on your CD terms.
Reach Maturity Date
Your CD term ends and you can access your principal plus interest penalty-free.
Decide What Happens Next
Withdraw funds, roll into a new CD, or transfer to another account.
Annual Percentage Yield (APY) differs from the stated interest rate because it includes the effect of compounding. If a CD offers a 4.00% interest rate with monthly compounding, the APY will be slightly higher, around 4.07%, because you earn interest on your interest.
When comparing CDs, always look at the APY rather than just the interest rate. APY gives you the true picture of what you will earn over a full year.
💡 Pro Tip:
CD rates fluctuate based on Federal Reserve policy. When the Fed raises interest rates, CD rates typically increase. Lock in attractive rates when you see them, as they may not last long.
If you withdraw money from a CD before maturity, you pay an early withdrawal penalty. This penalty typically equals 3 to 12 months of interest, depending on the CD term. For a 12-month CD, you might forfeit 6 months of interest. For a 5-year CD, you might lose a full year's worth.
Some CDs allow one penalty-free withdrawal, while others are more restrictive. Understanding these terms before opening a CD helps you avoid surprises if your financial situation changes.
Not all CDs function the same way. Financial institutions offer various CD products designed for different savings goals and financial situations. Understanding the differences helps you choose the right type for your needs.
Most common type
Higher minimums, better rates
Tax-advantaged retirement saving
Request rate increases
Withdraw without fees
Make additional deposits
Traditional CDs are the most straightforward option. You deposit a lump sum, choose your term length, and receive a fixed interest rate for that entire period. When the CD matures, you collect your principal plus all earned interest.
FSB offers traditional CDs with competitive rates across multiple term lengths. Whether you need short-term savings for a down payment or long-term growth for retirement, traditional CDs provide predictable returns.
Jumbo CDs require minimum deposits of $25,000 or more but offer higher interest rates in exchange. These work well for individuals or families with substantial savings who want to maximize returns while maintaining FDIC protection.
Before committing a large sum to a jumbo CD, ensure you won't need those funds before maturity. The early withdrawal penalties on jumbo CDs can be significant.
IRA CDs combine the safety of certificates with the tax advantages of Individual Retirement Accounts. Choose a Traditional IRA CD for tax-deferred growth or a Roth IRA CD for tax-free withdrawals in retirement.
These products make sense for conservative retirement savers who want guaranteed returns without stock market volatility. The annual contribution limits for IRAs apply, so plan accordingly.
CD rates fluctuate based on several factors including Federal Reserve policy, inflation, and bank funding needs. Generally, longer-term CDs offer higher rates because you commit your money for a longer period.
However, this relationship is not guaranteed. During periods when the Federal Reserve is expected to cut rates, shorter-term CDs might offer better rates than longer-term options. This creates an inverted yield curve.

The Federal Reserve influences CD rates through its federal funds rate policy. When the Fed raises rates to combat inflation, banks typically increase CD rates to attract deposits. When the Fed lowers rates to stimulate economic growth, CD rates usually fall.
Competition among banks also affects rates. Community banks like FSB often offer competitive rates to attract deposits from local savers, sometimes exceeding national average rates.
Match your CD term to when you will need the money. Planning a down payment in 18 months? Choose an 18-month CD. Saving for retirement in 30 years? Consider laddering multiple CD terms rather than locking everything into one long-term certificate.
Shorter terms provide flexibility if rates rise, while longer terms lock in current rates if you expect them to fall. Your choice depends on your financial timeline and interest rate outlook.
CDs compete with several other savings and investment vehicles for your money. Each option offers different combinations of return, risk, and liquidity. Understanding these tradeoffs helps you allocate your savings effectively.
| Account Type | Typical APY Range | Liquidity | Risk Level | Best For |
|---|---|---|---|---|
| Certificates of Deposit | 3.00% - 4.00% | Low | None | Guaranteed returns on funds you won't need soon |
| Savings Accounts | 0.40% - 4.50% | High | None | Emergency funds and money you need access to |
| Money Market Accounts | 3.00% - 5.00% | Medium | None | Higher balances with check-writing capability |
| Treasury Bills | 4.50% - 5.50% | Medium | None | Government-backed short-term savings |
| Bond Funds | 3.00% - 6.00% | High | Low-Medium | Conservative investors accepting some risk |
| Stock Market Index Funds | 8.00% - 12.00% (historical avg) | High | Medium-High | Long-term growth with volatility tolerance |
High-yield savings accounts offer competitive rates with full liquidity. You can withdraw anytime without penalty, making them ideal for emergency funds. However, the interest rate can change at any time, while CD rates are locked in.
Choose a high-yield savings account for your emergency fund and money you might need on short notice. Use CDs for savings earmarked for specific goals where you know you won't need the funds before maturity.
Money market accounts blend features of savings accounts and checking accounts. They typically offer competitive interest rates with limited check-writing capability. FSB's money market accounts provide flexibility while still earning solid returns.
Money market rates can fluctuate, while CD rates stay fixed. If you need occasional access to your funds but want to earn more than a basic savings account, money markets work well. If you want the highest guaranteed rate and won't need the money, choose a CD.
The stock market historically provides higher long-term returns than CDs, averaging around 10% annually over decades. However, stocks carry significant risk with no guarantee of positive returns in any given year.
CDs work best for short to medium-term savings where you cannot afford to lose principal. For long-term retirement savings, a balanced approach using both guaranteed products like CDs and growth investments like stocks often makes the most sense.
A CD ladder spreads your money across multiple CDs with staggered maturity dates. Instead of putting $20,000 into one 5-year CD, you might divide it into five $4,000 CDs maturing in 1, 2, 3, 4, and 5 years. This approach provides regular access to portions of your money while maintaining higher overall returns.
CD laddering balances the desire for higher interest rates on longer-term CDs with the need for periodic liquidity. As each CD matures, you can either use the funds or reinvest in a new CD at the longest term of your ladder.
Year 1 CD: $5,000 at 3.50% APY
Matures in 2027 → Reinvest in new 5-year CD or use funds
Year 2 CD: $5,000 at 4.00% APY
Matures in 2028 → Reinvest in new 5-year CD or use funds
Year 3 CD: $5,000 at 4.25% APY
Matures in 2029 → Reinvest in new 5-year CD or use funds
Year 4 CD: $5,000 at 4.50% APY
Matures in 2030 → Reinvest in new 5-year CD or use funds
Year 5 CD: $5,000 at 4.75% APY
Matures in 2031 → Reinvest in new 5-year CD or use funds
Result: After Year 1, you have a CD maturing every year while earning higher average rates than short-term CDs
Laddering provides flexibility in changing rate environments. If rates rise, your maturing CDs can be reinvested at the new higher rates. If rates fall, you still have CDs locked in at the previous higher rates. This hedges your interest rate risk.
You also maintain regular access to portions of your savings without paying early withdrawal penalties. This makes ladders ideal for retirees who need periodic income or savers building toward medium-term goals.
Start by determining your total savings amount and time horizon. Divide your funds equally across CDs with different maturity dates. A simple approach uses annual maturities, but you can also create quarterly or semi-annual ladders for more frequent access.
As each CD matures, decide whether to use the funds or reinvest. If reinvesting, choose the longest term in your ladder to maintain the structure. Over time, your entire ladder will consist of long-term CDs earning higher rates, but with regular maturity dates providing liquidity.
The Millers from Hiawatha had $30,000 in a single 5-year CD earning 4.00% APY. When it matured, they built a ladder with six $5,000 CDs in 1, 2, 3, 4, 5, and 6-year terms.
Before laddering: Entire $30,000 locked up with no access for 5 years. Average return: 4.00% APY.
After laddering: $5,000 available every year. Average return across all CDs: 4.35% APY. Greater flexibility with higher overall returns.
Their insight: "We sleep better knowing we have access to money every year if we need it, plus we're earning more than before."
CDs provide guaranteed returns with zero market risk, making them attractive for conservative savers. However, they require you to lock up your money and may not keep pace with inflation during low-rate periods.
CDs excel for specific savings goals with known timelines. Saving for a down payment in 2 years? A 24-month CD guarantees your money will grow safely. Planning a wedding in 18 months? An 18-month CD ensures funds are available when needed.
Retirees and conservative investors also benefit from CDs as part of a diversified portfolio. The guaranteed income from maturing CDs provides stability that complements other investments.
✓ A CD is right for you if:
✗ Consider alternatives if:
Don't put your emergency fund in a CD. Emergency money must be liquid and available within hours, not months. Keep 3-6 months of expenses in a regular savings or money market account instead.
Similarly, if you have high-interest debt like credit cards charging 20% or more, paying that off provides a guaranteed 20% "return" that far exceeds any CD rate. Handle expensive debt before locking money into CDs.
A Certificate of Deposit (CD) is a savings account that holds a fixed amount of money for a fixed period (term) at a guaranteed interest rate. When the term ends (matures), you receive your original deposit plus all earned interest. If you withdraw early, you typically pay a penalty.
CDs can be attractive when interest rates are high, which has been the case recently. They provide guaranteed returns with no market risk, making them excellent for short to medium-term savings goals. However, they may underperform stocks over long time periods and may not always keep pace with inflation.
When your CD reaches its maturity date, you enter a grace period (typically 7-10 days) when you can withdraw your funds without penalty, add money, or roll the CD into a new term. If you take no action, most banks automatically renew the CD for the same term at current rates.
Minimum deposit requirements vary by bank and CD type. FSB's traditional CDs typically require $500 minimum, while jumbo CDs require $25,000 or more. Some banks offer CDs with minimums as low as $100, while others require $10,000 or more.
CDs are FDIC insured up to $250,000 per depositor per bank, so you cannot lose your principal in the traditional sense. However, if you withdraw early and the penalty exceeds your earned interest, you could receive back less than your original deposit. Additionally, inflation can erode purchasing power over time.
A no-penalty CD (also called liquid CD) allows you to withdraw your money after a short initial period (usually 7 days) without paying an early withdrawal penalty. In exchange for this flexibility, these CDs typically offer lower interest rates than traditional CDs with the same term.
CD interest is taxed as ordinary income in the year it's earned, even if you don't withdraw it. Your bank will send you a 1099-INT form showing the interest earned. IRA CDs defer taxes until withdrawal (traditional IRA) or grow tax-free (Roth IRA), following normal IRA tax rules.
Choose a CD term that matches when you'll need the money. Short-term CDs (3-12 months) provide flexibility if you think rates might rise, while long-term CDs (3-5 years) lock in current rates longer. Consider building a CD ladder to balance both approaches and maintain regular access to portions of your savings.
Traditional CDs do not allow additional deposits after opening. However, add-on CDs specifically permit you to make additional deposits during the term, though these are less common and may offer slightly lower rates. All deposits in an add-on CD earn the same interest rate.
The interest rate is the stated rate the CD pays, while APY (Annual Percentage Yield) includes the effect of compounding. For example, a 4.00% interest rate with monthly compounding results in a 4.07% APY. Always compare CDs using APY for an accurate picture of your returns.
