CDs are similar to savings accounts in that they are insured and thus virtually riskfree; they are "money in the bank". CDs are insured by the Federal Deposit Insurance Corporation (FDIC) for banks and by the National Credit Union Administration (NCUA) for credit unions. They are different from savings accounts in that the CD has a specific, fixed term (often monthly, three months, six months, or one to five years), and, usually, a fixed interest rate. It is intended that the CD be held until maturity, at which time the money may be withdrawn together with the accrued interest.
In exchange for keeping the money on deposit for the agreed-on term, institutions usually grant higher interest rates than they do on accounts from which money may be withdrawn on demand, although this may not be the case in an inverted yield curve situation. Fixed rates are common, but some institutions offer CDs with various forms of variable rates. For example, in mid-2004, interest rates were expected to rise, many banks and credit unions began to offer CDs with a "bump-up" feature. These allow for a single readjustment of the interest rate, at a time of the consumer's choosing, during the term of the CD. Sometimes, CDs that are indexed to the stock market, the bond market, or other indices are introduced.
A few general guidelines for interest rates are:
- A larger principal should receive a higher interest rate, but may not.
- A longer term will usually receive a higher interest rate, except in the case of an inverted yield curve (i.e. preceding a recession)
- Smaller institutions tend to offer higher interest rates than larger ones.
- Personal CD accounts generally receive higher interest rates than business CD accounts.
- Banks and credit unions that are not insured by the FDIC or NCUA generally offer higher interest rates.
How CDs work 
CDs typically require a minimum deposit, and may offer higher rates for larger deposits. The best rates are generally offered on "Jumbo CDs" with minimum deposits of $100,000.
The consumer who opens a CD may receive a paper certificate, but it is now common for a CD to consist simply of a book entry and an item shown in the consumer's periodic bank statements; that is, there is often no "certificate" as such. Consumers who wish to have a hard copy verifying their CD purchase may request a paper statement from the bank or print out their own from the financial institution's online banking service.
Closing a CD 
Withdrawals before maturity are usually subject to a substantial penalty. For a five-year CD, this is often the loss of six months' interest. These penalties ensure that it is generally not in a holder's best interest to withdraw the money before maturity—unless the holder has another investment with significantly higher return or has a serious need for the money.
Commonly, institutions mail a notice to the CD holder shortly before the CD matures requesting directions. The notice usually offers the choice of withdrawing the principal and accumulated interest or "rolling it over" (depositing it into a new CD). Generally, a "window" is allowed after maturity where the CD holder can cash in the CD without penalty. In the absence of such directions, it is common for the institution to roll over the CD automatically, once again tying up the money for a period of time (though the CD holder may be able to specify at the time the CD is opened not to roll over the CD).
CD refinance 
Insured CDs are required by the Truth in Savings Regulation DD to state at the time of account opening the penalty for early withdrawal. It has been generally accepted that these penalties cannot be revised by the depository prior to maturity. However, there have been cases in which a credit union modified its early withdrawal penalty and made it retroactive on existing accounts. The second occurrence happened when Main Street Bank of Texas closed a group of CDs early without full payment of interest. The bank claimed the disclosures allowed them to do so.
The penalty for early withdrawal is the deterrent to allowing depositors to take advantage of subsequent enhanced investment opportunities during the term of the CD. In rising interest rate environments the penalty may be insufficient to discourage depositors from redeeming their deposit and reinvesting the proceeds after paying the applicable early withdrawal penalty. The added interest from the new higher yielding CD may more than offset the cost of the early withdrawal penalty.
While longer investment terms yield higher interest rates, longer terms also may result in a loss of opportunity to lock in higher interest rates in a rising-rate economy. A common mitigation strategy for this opportunity cost is the "CD ladder" strategy. In the ladder strategies, the investor distributes the deposits over a period of several years with the goal of having all one's money deposited at the longest term (and therefore the higher rate), but in a way that part of it matures annually. In this way, the depositor reaps the benefits of the longest-term rates while retaining the option to re-invest or withdraw the money in shorter-term intervals.
For example, an investor beginning a three-year ladder strategy would start by depositing equal amounts of money each into a 3-year CD, 2-year CD, and 1-year CD. From this point on, a CD will reach maturity every year, at which time the investor would re-invest at a 3-year term. After two years of this cycle, the investor would have all money deposited at a three-year rate, yet have one-third of the deposits mature every year (which can then be reinvested, augmented, or withdrawn).
The responsibility for maintaining the ladder falls on the depositor, not the financial institution. Because the ladder does not depend on the financial institution, depositors are free to distribute a ladder strategy across more than one bank, which can be advantageous as smaller banks may not offer the longer terms found at some larger banks. Although laddering is most common with CDs, this strategy may be employed on any time deposit account with similar terms.
Deposit insurance 
The amount of insurance coverage varies depending on how accounts for an individual or family are structured at the institution. The level of insurance is governed by complex FDIC and NCUA rules, available in FDIC and NCUA booklets or online. The standard insurance coverage is currently $250,000 per owner or depositor for single accounts or $250,000 per co-owner for joint accounts.
Some institutions use a private insurance company instead of, or in addition to, the Federally backed FDIC or NCUA deposit insurance. Institutions often stop using private supplemental insurance when they find that few customers have a high enough balance level to justify the additional cost.
The Certificate of Deposit Account Registry Service program allows investors to keep up to $50 million invested in CDs managed through one bank with full FDIC insurance. However rates will likely not be the highest available.
Terms and conditions 
There are many variations in the terms and conditions for CDs.
The federally required "Truth in Savings" booklet, or other disclosure document that gives the terms of the CD, must be made available before the purchase. Employees of the institution are generally not familiar with this information; only the written document carries legal weight. If the original issuing institution has merged with another institution, or if the CD is closed early by the purchaser, or there is some other issue, the purchaser will need to refer to the terms and conditions document to ensure that the withdrawal is processed following the original terms of the contract.
- The terms and conditions may be changeable. They may contain language such as "We can add to, delete or make any other changes ("Changes") we want to these Terms at any time."
- The CD may be callable. The terms may state that the bank or credit union can close the CD before the term ends.
- Payment of interest. Interest may be paid out as it is accrued or it may accumulate in the CD.
- Interest calculation. The CD may start earning interest from the date of deposit or from the start of the next month or quarter.
- Right to delay withdrawals. Institutions generally have the right to delay withdrawals for a specified period to stop a bank run.
- Withdrawal of principal. May be at the discretion of the financial institution. Withdrawal of principal below a certain minimum—or any withdrawal of principal at all—may require closure of the entire CD. A US Individual Retirement Account CD may allow withdrawal of IRA Required Minimum Distributions without a withdrawal penalty.
- Withdrawal of interest. May be limited to the most recent interest payment or allow for withdrawal of accumulated total interest since the CD was opened. Interest may be calculated to date of withdrawal or through the end of the last month or last quarter.
- Penalty for early withdrawal. May be measured in months of interest, may be calculated to be equal to the institution's current cost of replacing the money, or may use another formula. May or may not reduce the principal—for example, if principal is withdrawn three months after opening a CD with a six-month penalty.
- Fees. A fee may be specified for withdrawal or closure or for providing a certified check.
- Automatic renewal. The institution may or may not commit to sending a notice before automatic rollover at CD maturity. The institution may specify a grace period before automatically rolling over the CD to a new CD at maturity. Be careful as some otherwise respectable banks have been known to renew at scandalously low rates.
CD interest rates closely track inflation. For example, in one situation interest rates may be 15% and inflation may be 15%, and in another situation interest rates may be 2% and inflation may be 2%. Of course, these factors cancel out, so the real interest rate is the same in both cases.
In this situation, it is a misinterpretation that the interest is an increase in value. However, to keep the same value the rate of withdrawal must be the same as the real rate of return, in this case, zero. People may also think that the higher-rate situation is "better," when the real rate of return is actually the same.
Also, the above does not include taxes. When taxes are considered, the higher-rate situation above is worse, with a lower (more negative) real return, although the before-tax real rates of return are identical. The after-inflation, after-tax return is what's important.
It is a common belief that, "You don't make any money in bank accounts (in real economic terms), simply because you're not supposed to."; on the other hand, bank accounts and CDs are fine for holding cash for a short amount of time.
However this applies only to "average" CD interest rates. In reality, some banks pay much lower than average rates while others pay much higher rates (differences of 100% are not unusual, e.g., 2.50% vs 5.00%). In the United States, depositors can take advantage of the best FDIC-insured rates without increasing their risk. Furthermore, a long-term CD might have a high nominal interest rate with a relatively low real interest rate due to high inflation at the time of purchase (as indicated above); however inflation rates often change rapidly and the final real interest rate could be significantly higher than riskier investments.
Investors should be suspicious of an unusually high interest rate on a CD. Allen Stanford used fraudulent CDs with high rates to lure people into his Ponzi scheme.
Finally, the statement that "CD interest rates closely track inflation" is not necessarily true. For example, during a credit crunch banks are in dire need of funds and CD interest rate increases may not track inflation.
