Investment calculator is a simple tool which helps you estimate how much profit an investment will yield in the future, taking into account a fixed interest rate and duration of your investment. You can calculate both final balance of your investment and total interest. It also lets you determine these quantities while including a monthly contribution to your initial investment.
Asking yourself whether to make an investment or which product to choose? Planning a trip of a lifetime and wondering if your are going to gather the necessary sum? Are you on track with your financial goals? In all of these situations our investment calculator might come in handy. All you need to know is: how much you want to invest, what is the interest rate and how long are you willing to wait for return on your investment.
Let's try it on a simple example.
Your initial investment is 100 EUR.
Yearly interest rate is 5%.
To make it easier - you do not plan to contribute any amount of money during the period of your investment.
The duration of your investment is 3 years.
By investing 100 EUR at a 5% interest rate you will have 105 EUR - '100 EUR * 5%'
By the beginning of the second year your investment sum already equals 105 EUR. You multiply it again by 5% and get about 110 EUR
By the beginning of the third year your investment sum equals 110 EUR. You multiply it again by 5% and get 116 EUR.
If you're planning for a longer investment you need to carry out this operation for every year. Or... you could simply use our investment calculator to do it faster.
If you want to know how to calculate the final balance of your investment for a period of time, the equation is the same for any asset:
final_balance = initial_amount * (1 + interest_rate / compound_frequency)^(compound_frequency * years). The time period will usually be one year as interest rates are commonly calculated annually.
Compound interest is one the most powerful concepts in finance, which most financial/investment products are based on. What it means is that the interest you make every year/month (depending on the compound frequency) is added to your initial investment sum. This way money you invested grows at an increasing rate. Just like in our example above: after one year the interest is not calculated for the initial sum of 100 EUR but 105 EUR that you already made. Calculating future value of an invested sum with compound interest can be a bit tricky, so you might want to use our compound interest calculator.
Another popular term used in finance is return on investment (ROI). ROI tells you how efficient your investment is or lets you compare performance of a couple of investment options.
