An investment horizon: what is it and how do you determine it?
When you start investing , it is important to work out an investment strategy. An important part of this is the investment horizon . What exactly is that? And how do you do that, determine an investment horizon? In this blog we will discuss this in detail.
Definitions of an investment horizon
There are various definitions for the concept of investment horizon. Roughly speaking, there are two meanings to be distinguished when talking about this. The first meaning describes the investment horizon as “the period of time in which the investment for an investment can be missed”. The second meaning indicates it as “the period of time in which an investor wants to obtain the desired return for his investments at a certain risk”.
It may seem a bit strange that there is no clear definition of the term investment horizon, which is certainly not unimportant. This can be explained, however, because an investment horizon only takes shape when the two aforementioned meanings come together.
An investment horizon should be seen as the period in which the assets can be used for investments and are not needed for other matters. An investment horizon can differ greatly per investment and per person. It is also the case that the longer an investment horizon, the lower the investment risk . With a relatively short investment period, it is called a short investment horizon and you run more risk to obtain the desired return .
What does your investment horizon look like in practice?
Suppose you have a capital of €7,000 at your disposal and want to use this for investments for your child with the intention that he or she can start studying in 10 years. A certain return must then have been achieved with the investments made in order to be able to pay for the study. This means that your investment horizon is then 10 years.
It is wise to only invest in investment products that you can understand and that match your experience and financial knowledge. It is therefore very important to map out your own situation with the financial driving license and thus find out which financial products best fit your knowledge and acquired experience.

How do you determine your investment horizon?
An investment horizon is different for every investor. It is determined by personal circumstances and your current financial situation. The risk you want to take and your investment objectives also play a role. The following aspects are relevant when defining your own investment horizon.
The length of time you can survive without your investment capital.
This is an important question to ask yourself. This will determine the limit of your investment horizon. Here is an example. If you cannot survive without your investment funds for more than 15 years, you should set your horizon at a maximum of 15 years. This is the case, for example, if your mortgage has to be repaid in 15 years.
The amount of your investment capital.
In addition to determining the desired duration of the investments, it is also necessary to know how much money you can afford to lose. Our advice is to only use that money for investments that you do not need at all in the coming years to spend on other things. Your investment horizon is determined by the size of your deposit. The more money you invest in your investments, the faster the desired return is achieved.
In those situations where you do not want to invest a large amount at once, it is also possible to opt for periodic investing . You can then choose to invest a small amount of money every month and thus reduce the investment risk at the same time.The desired risk.
Thirdly, when determining your investment horizon, you consider what risk may be associated with your investments. Do you not mind taking more risk? In that case, you choose an offensive risk profile . However, if you are no longer sleeping well because of the possible price fluctuations and are afraid of losing money, then it is a better choice to simply go for less risk.
The desired level of return.
The next step is to determine how much profit you want to make. Sometimes this is already a fixed amount and you save for the purchase of something. However, it is also possible to set a minimum amount.
The feasibility.
Finally, ask yourself whether the set goals are realistic. Have you decided that you want to make 80% profit in a period of 2 years with as little risk as possible? Then the chance that this will succeed is not very big. Check whether the profit expectation, the deposit, the set risk and the time period need to be adjusted. These aspects are strongly linked. For example, you can opt for a lower risk profile with a longer investment horizon to achieve the same profit as is the case with a shorter investment horizon. It is therefore always good to opt for long-term investments.
Calculation of the feasibility of the chosen investment strategy.
With a clear example we will explain how the calculation of the feasibility of your investment objectives works. We will look at whether the goal of the investments can be achieved with a certain investment horizon.
First we determine some values to calculate with:
- The term
In the example, we assume that the investor is 45 years old and that the assets can be missed until the age of 67. At that age, the plan is to retire and the previous income will disappear. At that time, you want to be able to access your assets again. - The amount
You choose to invest €10,000, because you can easily afford to miss this amount. - The risk
Your willingness to take risks is average and you choose a neutral risk profile. The associated return will average 4.4% per year. - The desired return
You want to have accumulated a capital of €20,000 when you reach retirement age.
We then examine whether these investment goals are achievable within the established horizon. Is it a realistic investment horizon?
For a simple calculation, we take the average profit with a yield of 4.4% per year on your investments. In practice, the investment return can be significantly higher one year and negative the next.
We previously set the investment horizon to 22 years. With a profit expectation of 4.4% and an investment of €10,000, the calculation looks like this:
€10,000 x 1.044^22 = €25,788.
Based on the expected returns, the final total of the investments amounts to €25,788. This result is more than the original investment target of €20,000 at the time of retirement. Conclusion: the stated investment target is realistic and fits well with the investment horizon of this investor.
What is the minimum time of an investment horizon?
When determining your investment horizon, you are not necessarily bound to a minimum period. The period is largely determined by your ambitions, age and the type of investment product. For the most common investment products such as shares and bonds, an investment horizon of 5 years is usually assumed. Financial products such as leveraged securities can have an investment horizon of only a few days or hours.
Flexible investing with a specific investment horizon
It is good to know that you are not obliged to invest your money for the entire term of a once-set investment horizon. If you come to the conclusion that you want to have access to the money sooner due to changed ambitions, that is always possible. Of course, it makes less sense to provide for an investment horizon of decades only to have to come back to it after a few months and stop your investments.
