How To Calculate Compound Interest In 6 Easy Steps?

The main issue related to loans is that people don’t pay enough attention to additional expenses that they will have to pay overtime. One of those expenses is related to compound interest, which is a special form of interest that is growing over time and can be fixed to various periods like monthly, annually, and more. It is very important to be aware of this term when you are taking the loan since a certain model of funding might not be as effective as you were thinking in the beginning.

On the other hand, it is always recommended to make proper plans for your financial stability, and you can visit to learn more about different online tools, literature, and other resources that can help you to make the right moves.

On the other side, when you are investing in a saving account, the compound interest can improve its efficiency over time. Therefore, it is crucial to learn how to calculate it and determine the right option for any of your investments.

Here are some simple methods that can help you to calculate it.

1. Annual Model


When it comes to the annual compound interest rate, it represents the percentage that will increase the amount of saving or debt over one year. For instance, if you took a loan with a 5% interest rate per year, you will have to pay that amount each year related to the full value of the loan. Also, some financial institutions introduce more favorable options where the amount given through this interest will decrease as you are paying it out.

2. Determine the Rate for the First Year

It is important to understand that compound is affecting the amount of money to increase the rate over the rate after the first year. For example, if you invest $1,000 in your savings account, and the rate is 5%, you will have $1,050 after one year. In the second year, you will calculate the amount for $1,050.

3. Create Advanced Calculation


You should focus on a longer period, which is especially important if you want to get a loan. As you can see, even a difference of only 1% can make a big impact when you are investing in a savings account or taking a bigger loan that you will have to pay in the next 10 or 20 years. For example, investing $1,000 with a 5% rate will provide you with a profit of over $250 in the next five years.

4. Use Excel

This software is a perfect way to easily calculate this rate. You will have to create a table and add additional data about your loan or investment. It has an integrated system with formulas that can provide you with advanced calculation and you will have to add the starting amount, percentage rate, and several years. You will only need to type the Year 2, and the software will provide you with a detailed plan.

5. Learn the Process


It might seem as too complex to people with less experience in math and statistics. However, there is a simple formula that you can use to check the amount of interest that you will gain or pay over time. You will have to implement factors like principal, future value, frequency, and years. This will help you to determine the amount of money after a longer period, and it will be easier to find the best deals related to loans and investments.

Moreover, there are different models where you will need different calculations and formulas with more details. That is the case with interests that are not measured annually, but per month, day, and other periods. The frequency is the factor that you will add to that form of measurement. If you are not sure that you are doing it correctly, you can find some online tools that will calculate it for you.

6. What About Monthly Installments?

When it comes to formula, it appears to be even more complex. However, you will only add another factor to it, which is related to monthly fees. This is common for loans and leases where you are paying monthly installments. In most cases, compound rates are much lower because it would prolong the payment time in another way.

Advantages of Compound Interest

The main advantage is related to your investment. The financial institutions that are using this rate will provide you with higher profits over time. For example, if you invest with a rate of 10%, the amount of $1,000 will provide you with a profit of an additional $6,000 over a period of 20 years. When it comes to simple interest, you can get 50% of the amount in 10 years, while compound one gives you over 62%.

Last Words

The best options where you can acquire higher profit over time with this feature are savings accounts, bank accounts, and investments. Also, banks are often using it as a way to motivate people to return the loan in a determined time. If you are delaying your payments, the compound will make your expenses much higher over time. However, you cannot expect higher rates in most of these cases, especially when it comes to bank accounts, where an average amount is under 0.3%.

Also, it is crucial to learn the difference between the basic rate and this model since the amount of money you gain or owe over time can be much higher depending on the amount of compounding. Besides that, it is important to consider other factors related to the interest, such as risks, inflation, liquidity, and more.

When it comes to the calculating process, you only need to know the basic parts of the formula and details of the loan or investment. The great thing is that you can find various online tools where you can easily get more details about the financial terms in the following years where this type of rate is applied. That will help you to make better financial choices.
