Investing is the act of using money to make more money. The Investment Calculator can help determine one of many different variables concerning investments with a fixed rate of return.
Variables involved
For any typical financial investment, there are four crucial elements that make up the investment.
- Return rate – For many investors, this is what matters most. On the surface, it appears as a plain percentage, but it is the cold, hard number used to compare the attractiveness of various sorts of financial investments.
- Starting amount – Sometimes called the principal, this is the amount apparent at the inception of the investment. In practical investing terms, it can be a large amount saved up for a home, an inheritance, or the purchase price of a quantity of gold.
- End amount – The desired amount at the end of the life of the investment.
- Investment length – The length of the life of the investment. Generally, the longer the investment, the riskier it becomes due to the unforeseeable future. Normally, the more periods involved in an investment, the more compounding of return is accrued and the greater the rewards.
- Additional contribution – Commonly referred to as annuity payment in financial jargon, investments can be made without them. However, any additional contributions during the life of an investment will result in a more accrued return and a higher end value.
