How does this investment calculator work?

This personal finance tool can help you get an idea how an investment or savings portfolio can grow over the time you specify and by taking account of your assumptions. You need to provide the following details:

  • Your initial capital which is the amount of money you have available and want to invest or deposit;
  • Annual contribution is the value you assume you would be able to add year by year to the initial deposited amount. Please note it is an optional value and can be left blank;
  • Interest rate is the return on investment rate you expect. Usually the return rate is a measure of the exposure to risks that is why its level varies from one instrument to another. Specialists say that a risky portfolio usually offers a higher interest rate than a safer one. Please note that when speaking about risks you should take account of the probability that the risk take place. At the opposite side are financial instruments with low risk profile which are characterized by smaller interest rates, that is why you should always keep a balance between potential return and risks.
  • Number of years is the term in years you are available to keep your investment plan;
  • Reinvested profit percentage is the percent of the reinvested profit. The higher this rate is, the higher your balance will grow over time; while small amount from the profit will go directly to your pocket during the time you continue investing.

Please remember that this investment calculator should be used for hypothetical demonstrative purposes only while for a more detailed plan you should seek a financial professional.

How people keep their savings?

Most people prefer to deposit their money either in certificates of deposit with fixed interest rates or saving accounts with or without instant access to their funds. This option is preferred due to the fact it is a quick and easy instrument accessible even through internet banking service and because it is one of the most safest investment.

A smaller number of people are willing to invest in things considered a bit riskier than deposits. These are considered stock and forex exchange market as well as on local, national or international bonds.

Even a smaller number of people are investing in private equity funds financing technology, green energy projects, start-ups and small business ideas because of a higher level of uncertainty.

Based on their preferences in keeping their money in a safe place people may be categorized in 2 major groups:

  • People with adversity to risk.
  • People with risk appetite.

Another perspective that may explain how people prefer keeping their money or how open they are to invest is related to the time frame they expect receiving their money back. From this point of view many people prefer making deposits because in this case the term is fixed and it is under their control, while in case of an investment in a start up for instance, the term to receive their investment back is not that predictable which makes it unattractive. That is why if we would try categorizing people by this criterion there are:

  • People open to place an investment on an uncertain time frame;
  • People oriented to a fixed time frame for their resources.

Moreover people’s behavior in regard of investments can be explained by the time they expect to receive not only their money but their profits too. Taking account of this aspect, most of people prefer smaller time frames which make them use deposits and highly liquid instruments, while there are very few people willing to receive their profits in a longer term.

How to assess an investment opportunity?

By taking account of what specialists and researchers have found, when trying to assess an investment opportunity you really need to have a clear answer on the following questions:

  • What are the risks associated with the opportunity and what is their likeliness and impact in case they take place?
  • Which is the return rate the instrument offers? Is it fixed or variable? It was assessed in an objective way or not? It is higher than the interest rate or below it? Is it higher or lower than in case of other option having the same risk profile?
  • What time frame are you available to keep your money in?
  • What are the perspectives of the investment you assess?
  • What is the time frame you expect return from your investment?
