CD: What it is, How it works, and How much you earn 2026

When choosing where and how to invest, we encounter almost infinite options. There are as many investment options as there are investor profiles. Today, we're here to tell you about one of them: CDTs. If you don't know what they are or aren't clear on them, don't worry. In this post, we'll explain in a comprehensive yet simple way what a CDT is, how they work, what types exist, how to start investing in them, their advantages, risks, and everything else you need to know. 

What is a CDT?

A Certificate of Deposit (CDT) is a financial product offered by banks that allows individuals to invest a sum of money for a fixed term, receiving a pre-agreed fixed interest rate in return.

Characteristics of a CDT

For a financial product to be considered a CDT, it must meet the following characteristics:

• Fixed-term investment: The investor must deposit a sum of money in the bank for a specified period, which can range from 30 days to several years. During this term, the money cannot be withdrawn from the account without penalty.
• Fixed interest rate: The bank will establish a fixed interest rate for the CDT, which is applied to the deposited amount throughout the entire investment term. This interest rate is generally higher than what is offered by interest-bearing accounts traditional savings accounts.
• Security: CDT deposits are protected up to a certain amount per client and financial institution. This means that, in the event of bank insolvency, the investor would recover at least a portion of their investment.
• Liquidity: Some CDTs offer an early liquidity option, which allows the investor to withdraw their money before the term matures. However, this option is usually subject to penalties on the interest.
• Initial investment: The minimum investment amount for a CDT will vary depending on the financial institution and the type of CDT. Generally, the initial investment is usually relatively low.
• Return: They have a determined return, which will depend on the fixed interest rate and the investment term. The longer the term, the higher the return. 

Types of CDTs

Currently, there are various types of CDTs, which we'll outline below:

• Traditional: This is the most common type. It is characterized by offering a fixed interest rate and a predetermined investment term. 
• Online or Digital: This type of CDT can be opened and managed through digital channels, such as online banking or mobile banking. 
• Variable: Unlike traditional CDTs, which offer a fixed interest rate, variable-rate CDTs offer a rate that fluctuates according to a market indicator, such as the DIAN rate. This means that the profitability of this type can be higher or lower than that of a traditional CDT, depending on market conditions.
• Specialized Investment: This allows investors to invest in a specific economic sector or activity, such as real estate or agriculture. Specialized investment CDTs typically offer higher returns than traditional CDTs, but they also carry greater risk.
• With Early Interest Payment: This type of CDT allows investors to receive the interest generated by their investment periodically, for example, monthly or quarterly. This can be a good option for investors who need regular access to their interest earnings.
• With Interest Reinvestment Option: This type allows investors to reinvest the interest generated by their investment, which increases the invested capital and, consequently, the final return.

How Do CDTs Work?

How certificates of deposit work is relatively simple:

A sum of money is deposited in the bank.

• The minimum investment amount varies depending on the financial institution and the type of CDT.
• The money must be deposited into a special account for CDTs.

The bank sets a fixed interest rate for the CDT.

• The interest rate is applied to the amount deposited for the entire investment term.

The investor chooses an investment term.

• This investment term can range from 30 days to several years.
• During this term, the money cannot be withdrawn from the account without penalty.

The bank pays the interest to the investor upon maturity.

• The interest can be paid in one lump sum or periodically, depending on the chosen CDT.
• The interest generated is subject to Income Tax.

Investment Withdrawal Upon Maturity

• Upon maturity, the investor can withdraw their initial capital plus the interest generated.
• In some cases, the investor can opt to renew the CDT for a new term.

Benefits of Investing in CDTs

CDT investments are widely used and recommended because they offer the following benefits:

Security

They are a secure investment, as the invested capital is protected up to a certain amount per client and financial institution. This means that, should the financial institution where you invest face financial difficulties, your money will be safe.

Predictable Returns

CDTs offer a fixed interest rate for the entire investment term. This allows you to know in advance how much you will earn from your investment, making financial planning much easier.

Liquidity

CDTs are liquid investments, meaning you can withdraw your money at maturity without penalty. You can withdraw your money early, but you will likely have to pay a certain fee.

Diversification

They are ideal options to start diversifying investments in a portfolio due to the level of security they offer. This also makes them ideal for first-time investors with a very limited risk tolerance. 

Low Costs

They are a low-cost investment, as they typically do not have commissions or additional fees.

Ease of Investment

Investing in a CDT is a simple and quick process. Most likely, you can open a CDT at your trusted bank, the one you already use. 

Risks of Investing in CDTs

While certificates of deposit offer various benefits such as dividend investment, it's also important to consider the risks associated with this savings financial product:

Market Risk

Market interest rates will fluctuate, negatively impacting investment returns. If interest rates fall during the CDT term, you will earn less than expected.

Inflation Risk

Inflation erodes the purchasing power of money over time. If the inflation rate increases during the CDT term, the investment could lose its net asset value real value. This means you could buy fewer goods and services with the same amount of money at maturity.

Liquidity Risk

If you need to withdraw your money before the CDT matures, you will likely have to pay a penalty. This penalty can significantly reduce your earnings or even result in losses.

Default Risk

If the financial institution where you invested experiences financial difficulties, you may not be able to recover your full investment. While the principal is protected, this is only up to a certain amount, and this amount might not be sufficient to cover your entire investment.
