A certificate of deposit (CD) is a type of savings account that holds your funds for a set period of time, or term. In exchange, the bank pays you a fixed annual percentage yield (APY), which tends to be higher than what you could earn in a traditional savings account.

When you open a CD, you can typically choose between a short-term CD (one year or less), mid-term CD (two to three years), or long-term CD (four years or longer). Generally, the longer the term of the CD, the higher the interest rate will be. However, these days, that’s not always the case. Nonetheless, APY is one of several factors to consider when deciding which type of CD is right for you.

How Do CDs Work?

A certificate of deposit is a type of deposit account offered by a variety of financial institutions, including brick-and-mortar banks, online banks, and credit unions. When you open a CD, you make a lump sum deposit then agree to leave the money untouched until the end of the CD’s term.

Unlike a regular savings account, you typically can’t add money to a CD after your initial deposit. And if you withdraw money before the end of the CD’s term, you will likely get hit with an early withdrawal penalty.

There are some no-penalty CDs on the market that don’t charge a fee for pulling your money out early, but be sure you understand the terms and potential tradeoffs with regard to lower rates or fees.

Are CDs Insured?

Yes, CDs are typically insured by the Federal Deposit Insurance Corporation (FDIC) for up to $250,000, which makes them a relatively safe investment. Any money you deposit, up to $250,000, would be covered in the event of fraud or a bank collapse.

If the CD is issued by a credit union, it would be insured for the same amount, by the National Credit Union Administration (NCUA).

What Is a Short-Term CD?

Short-term CDs are CDs with terms of one year or less. Different banks offer CDs with different terms, but 3-month, 6-month, and one-year CDs are common.

A short-term CD gives you greater flexibility than a longer-term CD, since you’ll have access to your money sooner. But a short-term CD will also typically offer a lower annual percentage yield (APY) than a CD with a longer maturity date.

Advantages and Disadvantages of Short-Term CDs

Short-term CDs come with both pros and cons. Here are some to consider.

Advantages of Short-Term CDs

•   They typically pay a higher interest rate than traditional savings accounts.

•   They offer a safe place to park savings for a big purchase, while earning a steady rate.

•   If rates change or your needs shift, you won’t have to wait long to access your money.

Disadvantages of Short-Term CDs

•   They may offer lower interest rates than long-term CDs.

•   You may be able to find higher rates with other financial products, such as a high-yield savings account.

•   If you need the money before the CD matures, you’ll have to pay an early withdrawal penalty.

What Is a Long-Term CD?

Generally speaking, a long-term certificate of deposit is a CD that has a term of four years or more. Long-term CDs typically offer the highest rates of any type of CD, but the returns you’ll earn even with a long-term CD tend to be lower than historical stock market averages. That said, the beauty of CDs is that they offer a predictable rate of return, in a vehicle that’s relatively low risk.

The tradeoff to the higher interest rates that come with long-term CDs is that you won’t have access to your money for several years without paying a penalty.

Advantages and Disadvantages of Long-Term CDs

As with short-term CDs, long-term CDs come with both benefits and drawbacks. Here are some to keep in mind.

Advantages of Long-Term CDs

•   They typically offer the highest interest rates of any type of CD.

•   The predictable rate of return can help balance more volatile investments in your portfolio.

•   Knowing that you’ll incur penalties for early withdrawal can deter you from dipping into your savings prematurely.

Disadvantages of Long-Term CDs

•   If you end up needing to take money out before the term is over, you will likely get hit with early withdrawal penalty fees.

•   Some long-term CDs require a minimum opening deposit of $1,000 or more.

•   There’s a risk that inflation or interest rates will go up while your money is tied up in the CD.

Main Differences Between Short-Term and Long-Term CDs

Here’s a look at how short- and long-term CDs compare side-by-side.

When Should I Consider a Short-Term or Long-Term CD Over the Other?

Whether you should go with a short-term or long-term CD will depend on your financial goals, the amount of money you can afford to lock away, and your need for flexibility.

Consider a short-term CD if:

•   You may need access to your funds in the near future.

•   You want to take advantage of potentially higher interest rates compared to traditional savings accounts.

•   You are uncertain about future interest rate changes and want to reassess your options sooner.

Consider a long-term CD if:

•   You have money you want to set aside for a specific purpose that won’t happen for several years.

•   You want to maximize your earnings with potentially higher long-term CD interest rates.

•   You are confident you won’t need access to the funds before the CD matures.

It’s also important to consider your overall financial situation, including emergency savings, other investments, and financial goals, before deciding between short-term or long-term CDs.

The Takeaway

Opening a CD can be a smart way to earn a higher interest rate than you’d get from a traditional savings account. The tradeoff is that most CDs will charge an early withdrawal penalty if you remove your money before the end of the CD’s term, so you have to be willing to lock up your funds for the specific term of the CD you choose.

Generally, CDs with longer terms offer higher interest rates than shorter-term CDs, but this isn’t always the case so it’s a good idea to shop around and compare rates before opening a CD. You may also be able to find competitive rates with other types of accounts, like high-yield savings accounts.

FAQ

Is a long-term or short-term CD better?

It depends on your financial goals and circumstances. If you have funds you can comfortably lock away for a longer period and want to earn a potentially higher interest rate, a long-term certificate of deposit (CD) might be better. If you need more flexibility or anticipate needing the funds in the near future, a short-term CD might be a better fit.

How are rates different between short-term and long-term CDs?

Certificate of deposit (CD) rates can vary widely, but generally the longer the CD term, the higher the interest rate. Short-term CDs (usually up to one year) tend to offer lower interest rates compared to long-term CDs (four years or more).

SOBK-Q224-1848021-V1

Adding supplementary credit cards — credit cards tied to a primary credit card account — can be a good way to help someone establish credit. For example, adding a supplementary credit card for a child can help them build credit, since they will get the benefit of the primary cardholder’s good credit history. Someone working to rebuild their credit could also benefit.

Still, it’s important to keep in mind that the primary cardholder is responsible for any charges made by any authorized users on the account. Read on to learn more about who can benefit from a supplementary credit card and the pros and cons of adding an authorized user to your account.

What Is a Supplementary Credit Card?

A supplementary credit card, also known as an authorized user credit card, is a secondary credit card tied to the account of an existing user. This existing user could be a trusted friend, family member, or caregiver. The primary cardholder is responsible for all charges made by any authorized users or supplementary credit card holders.

Recommended: What Is Considered a Fair Credit Score?

How Do Supplementary Credit Cards Work?

When you add a supplementary credit card to your credit card account, your credit card company will send a new physical card. The credit card issuer will typically mail the card to the address of the primary cardholder in order to prevent fraud.

In some cases, the supplementary credit card number will be the same as the card number of the primary credit card. In other cases, it may have a different number. Either way, all charges made on the account — including those made by supplementary cardholders — are the responsibility of the primary cardholder.

Supplementary Credit Card Annual Fees

For most credit cards, there is not a charge to add a supplementary credit card or authorized user. However, some premium cards, such as The Platinum Card from American Express, do charge an annual fee for additional cards.

Supplementary Credit Card Sign-Up Bonuses

Typically there is not a sign-up bonus or welcome offer for adding a supplementary card user. If you want to enjoy credit card bonuses, you must apply as the primary account holder.

Supplementary Credit Card Earnings and Redemption Rates

The earnings rates for supplementary credit cards are the same as the rates for the primary credit cardholder. Because the primary cardholder is financially responsible for all charges, they will receive the benefits of all rewards, regardless of which account makes the charges.

Who Needs a Supplementary Credit Card?

A supplementary credit card can be useful for someone who does not meet the credit card requirements to qualify for a credit card on their own.

For instance, you can get a supplementary card for a child to help them establish credit. Adding them to your account also offers an opportunity for you to teach them the ins and outs of using a credit card responsibly.

You might also add a trusted friend or family member to your account to help them build their credit score although this will depend on the primary cardholder keeping the account in good standing. Another reason you might add an authorized user to your account is to allow them to take advantage of travel or other benefits when you are not with them.

It’s also possible to add someone as an authorized user without actually giving them a card. This can allow them to enjoy the benefits to their credit score without the risk that they’ll overspend or otherwise use the card irresponsibly.

Pros and Cons of Supplementary Credit Cards

While there are benefits to supplementary credit cards, there are also downsides that are worth noting. Consider these pros and cons.

Do Supplementary Credit Cards Affect Your Credit Score?

Yes, using a supplementary credit card can affect the credit score of both the primary and the secondary user. Depending on how a credit card is used, the effects could be either positive or negative.

If all cardholders on the account use their credit card responsibly, a supplementary credit card can have a positive impact on their credit scores due to how credit cards work. However, if the supplementary cardholder makes charges that the primary cardholder can’t repay, both of their credit scores could go down. Similarly, if the primary cardholder fails to make on-time payments, that could hurt the supplementary cardholder’s credit rather than helping it.

This is why it’s important that both cardholders are on the same page when it comes to credit card rules and best practices.

Recommended: When Are Credit Card Payments Due

How Much Do Supplementary Credit Cards Cost?

In most cases, there is no charge for adding supplementary credit cards or authorized user cards. However, some credit card issuers do charge an additional fee for adding supplementary cards. Make sure to check with your issuer before ordering one.

Applying for a Supplementary Credit Card

Because any supplementary credit cards are tied to the account of the primary cardholder, you can’t apply for a supplementary credit card directly. Instead, the primary cardholder will need to request an additional card directly from the issuer.

To do so, the primary cardholder can either call the customer service number listed on the back of their credit card or request an additional card through their online account or app.

Alternatives to Supplementary Credit Card

Opening a supplementary credit card can be a good way to help a family member build their credit, but it does come with some risk. One alternative to giving someone a supplementary credit card is to open a supplementary credit card account but keep the actual card.

With this arrangement, the authorized user gets the advantages of a supplementary account — namely, building their credit through the primary cardholder’s responsible use — without the risk that they will use their card irresponsibly.

The Takeaway

Supplementary credit cards, or authorized user cards, are additional cards tied to the credit card account of a primary cardholder. When used responsibly, they can help the authorized user build or establish credit. However, the primary account holder is responsible for all charges made by supplementary cardholders, so there is also some risk if the supplementary credit card is used irresponsibly.

Whether you're looking to build credit, apply for a new credit card, or save money with the cards you have, it's important to understand the options that are best for you. Learn more about credit cards by exploring this credit card guide.

FAQ

Are bills paid with the card number of the primary or supplementary card?

The card numbers of the primary and supplementary cards are both tied to the primary cardholder’s account. As such, the primary cardholder is responsible for all charges made, including by authorized users.

Is a supplementary credit card the same as a joint card?

A joint credit card account allows two people to use the same credit card account, with both account owners holding responsibility for all charges made to the account. In contrast, a supplementary credit cardholder is not responsible for charges they make. Instead, only the primary cardholder is financially responsible for all charges made by any user.

Who is responsible for a supplementary credit card?

Only the primary account holder is responsible for charges made by any and all authorized users. Any secondary or supplementary cardholders are not considered financially liable for any charges they make.

Does a supplementary card affect credit score?

Yes, having a supplementary card can affect your credit score. It can help build credit when used responsibly. But because the primary cardholder is ultimately responsible for all charges, their credit could suffer if an authorized user uses the card irresponsibly. An authorized user could also see their score suffer if the primary account holder fails to manage their account responsibly.

SOCC-Q224-1910822-V1

An IRA account with limited margin is a retirement account that allows investors to trade securities with unsettled cash. It’s a more lenient structure versus a cash account, where you must wait for trades to settle before using the money for further trading. But an IRA account with limited margin isn’t a true margin account in that you can’t use leverage.

Nonetheless, an IRA account with limited margin offers a few advantages, including the ability to defer or avoid short-term capital gains tax, and you’re protected against good faith violations. That said, there are still restrictions, so before setting one up, it may be beneficial to learn more about how these accounts work.

What Is an IRA Account With Limited Margin?

An IRA account that may have limited margin — often called simply a limited margin IRA — presents a more flexible option to invest for retirement than a traditional IRA. These types of IRAs may allow you to trade with unsettled funds, meaning that if you close a position you don’t have to wait the standard two days after you trade, you can use those funds right away.

There may also be tax benefits. In a traditional IRA margin account, capital gains taxes are deferred until funds are withdrawn. This is similar to a regular IRA, where you don’t pay taxes on contributions or gains until you withdraw your money.

You may also be able to use limited margin in a Roth IRA, and there may be even more tax benefits when using limited margin in a Roth IRA. You don’t pay any capital gains because Roth accounts are tax-free, since Roth contributions are made with after-tax money.

As noted, an IRA account with limited margin may allow investors to trade with unsettled cash. However, a limited margin IRA is just that — limited. It is not a true margin account, and does not allow you to short stocks or use leverage by borrowing money to trade with margin debits. In that sense, it is different from margin trading in a taxable brokerage account.

You may be able to use limited margin in several IRA types. In addition to having margin IRAs with traditional and Roth accounts, rollover IRAs, SEP IRAs, and even small business SIMPLE IRAs are eligible for the margin feature. While mutual funds are often owned inside an IRA, you cannot buy mutual funds on margin.

💡 Quick Tip: How to manage potential risk factors in a self-directed investment account? Doing your research and employing strategies like dollar-cost averaging and diversification may help mitigate financial risk when trading stocks.

How Does Limited Margin Work?

Limited margin works by allowing investors to trade securities without having to wait for funds to settle. You can think of it like an advance payment from positions recently sold.

The first step is to open an IRA account and request that the IRA margin feature be added. Once approved, you might have to request that your broker move positions from cash to margin within the IRA. This operational task will also set future trades to the margin type.

IRAs with limited margin will state your intraday buying power — you should use this balance when day trading stocks and options in the IRA.

An advantage to trading in limited margin IRAs is that you can avoid or defer capital gains tax. Assuming you earn profits from trading, that can be a major annual savings versus day trading in a taxable brokerage account. If you trade within a pre-tax account, such as a traditional or rollover IRA, then you simply pay income tax upon the withdrawal of funds. When using Roth IRA margin, your account can grow tax-free forever in some cases.

The drawback with an IRA with limited margin versus day trading in a taxable account is you are unable to borrow money from your broker to create margin debits. You are also unable to sell securities short with an IRA with limited margin account. So while it is a margin account, you do not have all the bells and whistles of a full margin account that is not an IRA.

Who Is Eligible for an IRA With Limited Margin?

Some brokerage firms have strict eligibility requirements such as a minimum equity threshold (similar to the minimum balances required in full margin accounts). When signing up, you might also be required to indicate that your investment objective is the “most aggressive.” That gives the broker a clue that you will use the account for active trading purposes.

Another restriction is that you might not be able to choose an FDIC-insured cash position. That’s not a major issue for most investors since you can elect a safe money market fund instead.

IRA Margin Calls

An advantage to having margin in an IRA is that you can more easily avoid margin calls by not having to wait for cash from the proceeds of a sale to settle, but margin calls can still happen. If the IRA margin equity amount drops below a certain amount (often $25,000, but it can vary by broker), then a day trade minimum equity call is issued. Until you meet the call, you are limited to closing positions only.

To meet the IRA margin call, you just have to deposit more cash or marginable securities. Since it is an IRA, there are annual contribution limits that you cannot exceed, so adding funds might be tricky.

💡 Quick Tip: One of the advantages of using a margin account, if you qualify, is that a margin loan gives you the ability to buy more securities. Be sure to understand the terms of the margin account, though, as buying on margin includes the risk of bigger losses.

Avoiding Good Faith Violations

A good faith violation happens when you purchase a security in a cash account then sell before paying for the purchase with settled cash. You must wait for the funds to settle — the standard is trade date plus two days (T+2 settlement) for equity securities. Only cash and funds from sale proceeds are considered “settled funds.” Cash accounts and margin accounts have different rules to know about.

A good faith violation can happen in an IRA account without margin. For example, if you buy a stock in the morning, sell it in the afternoon, then use those proceeds to do another round-trip trade before the funds settle, that second sale can trigger a good faith violation. Having margin in an IRA prevents good faith violations in that instance since an IRA with limited margin allows you to trade with unsettled funds.

Pros and Cons of Limited Margin Trading in an IRA

Can IRA accounts have margin? Yes. Can you use margin in a Roth IRA? Yes. Should your IRA have the limited margin feature added? It depends on your preferences. Below are the pros and cons to consider with IRAs with limited margin.

The Takeaway

An IRA account with limited margin allows people investing in individual retirement accounts to trade securities a bit more freely versus a cash account. The main benefit to having an IRA with limited margin is that you can buy and sell stocks and options without waiting for lengthy settlement periods associated with a non-margin account.

But remember: Unlike a normal margin account, this type doesn’t allow you to use leverage. That means a margin-equipped IRA doesn’t permit margin trading that creates margin debit balances. You are also not allowed to have naked options positions or engage in selling shares short.

Invest in what matters most to you with SoFi Active Invest. In a self-directed account provided by SoFi Securities, you can trade stocks, exchange-traded funds (ETFs), mutual funds, alternative funds, options, and more — all while paying $0 commission on every trade.

FAQ

Is an IRA a cash or a margin account?

An IRA can either be a cash account or a limited margin account. While a cash account only lets you buy and sell securities with a traditional settlement period, a limited margin IRA might offer same-day settlement of trades. You are not allowed to borrow funds or short sell, however.

Is day trading possible in an IRA?

Yes. You can day trade in your IRA, and it can actually be a tax-savvy practice. Short-term capital gains can add up when you day trade in a taxable brokerage account. That tax liability can eat into your profits. With a limited margin IRA that offers same-day settlement, however, you can buy and sell stocks and options without the many tax consequences of a non-IRA. The downside is that, in the case of losses, you cannot take advantage of the $3,000 capital loss tax deduction because an IRA is a tax-sheltered account. Another feature that is limited when day trading an IRA is that you cannot borrow funds to control more capital. A final drawback is that you are limited to going long shares, not short.

Can a 401(k) be a margin account?

Most 401(k) plans do not allow participants to have the margin feature. An emerging type of small business 401(k) plan — the solo brokerage 401(k) — allows participants to have a margin feature. Not all providers allow it, though. Also, just because the account has the margin feature, it does not mean you can borrow money from the broker to buy securities.
