What is compound interest?

Compound interest, or interest on interest, is a method of charging interest in a that the interest calculated in each period is added to the principal to calculate the interest in the next period and so on. In this way, the amount receivable or payable will be corrected by the interest rate and will be calculated on the new amount.

In other words, imagine that you put $100.00 into a compound interest application yielding at a rate of 10% per month, in the first month your capital earned $10.00 and this amount is added to the capital adding $110.00 for the following month to yield another 10% which will yield $11.00 and totaling $121.00 and so on.

What is the difference between compound interest and simple interest?

While in compound interest we have the yield that is added to the initial amount to yield more in the next yield, in simple interest this does not happen because the income will always be levied on the initial amount, hence the name of simple interest.

Let's review the example of a loan of $100.00 as simple interest. Now imagine that you put $100.00 in a simple interest application yielding at a rate of 10% per month, so every month your application will yield $10.00, which is the amount referring to 10% of $100.00.

How to calculate compound interest?

The formula for calculating compound interest is:

Fv = Iv (1 + i) ^ t

where

  • Fv:  The final value at the end of the periods
  • Iv:  The initial value
  • i:  The interest rate
  • t:  The time or number of periods

You can use our basic calculator to calculate compound interest according to the formula.

Tips for maximizing your compound interest earnings

Investing in compound interest can be a great way to make your money grow. However, it is important to know how to maximize your earnings to make the most of this investment strategy. Here are some tips and suggestions that can help you earn more with compound interest:

  • Start investing as soon as possible  Time is one of the most important factors when it comes to compound interest. The sooner you start investing, the more time you have for your money to grow. Even if you start with a small investment, with time and regular application of compound interest, your money can grow exponentially.
  • Make regular contributions  In addition to investing as early as possible, it's important to make regular contributions to maximize your earnings. The more money you invest, the more money you have to apply compound interest. Even small regular contributions can make a big difference over time.
  • Stay consistent  Maintaining a consistent strategy is key to maximizing your compound interest earnings. When deciding how much to invest and when, it is important to stick with this strategy for a long period of time. Constant changes in investment strategy can disrupt the compounding process and hurt your earnings.
  • Research and compare interest rates  Don't forget to research and compare the interest rates offered by different types of investments. Investments with compound interest can have different interest rates, so it is important to choose the best investment for your profile and objective.
  • Avoid premature withdrawals  Withdrawing your money ahead of time can drastically reduce your compound interest earnings. It is important to keep your money invested for a long period of time to maximize your earnings. Try to avoid premature withdrawals unless absolutely necessary.

With these tips, you can maximize your compound interest earnings and get the most out of your compound interest calculator. Remember, the key to maximizing your earnings is investing as early as possible, contributing regularly, staying consistent, researching and comparing interest rates, and avoiding premature withdrawals.

Example of compound interest

Imagine that Peter borrowed $1,000.00 from Susan, who agreed to receive the amount corrected by compound interest at a rate of 10% per month to receive in 12 months. The formula would look like this:

Fv = 1,000 (1 + 0.1) ^ 12

Fv = 1,000 * 1.1 ^ 12

Fv = 1,000 * 3.138428377

Fv = 3,138.43

Peter must pay Susan $3138.43 divided into 12 installments.

Note: In the formula, the interest rate must be divided by 100.
