Many of us come across a term “compound interest” when managing our savings and making investments. It is printed on the brochure of every bank, saving schemes and investment companies. While most of us know the meaning and implication of this term, many still find it difficult to understand it completely. However, young generation is more aware of Compound Interest Rate Formula and its implications as it is taught in elementary classes as well as at higher level. In simple word, compound interest is said to occur when interest on the initial principal is added to the principal amount so that it earns an interest. This process is called compounding.

Compounding has many useful applications in banks and other economic institutions. For a full definition of interest rate, compounding frequency and the interest rate need to be disclosed. This is the reason that banks and other financial institutions are legally bound to disclose interest rate as a yearly percentage. Other names of this yearly rate are annual percentage rate, annual equivalent rate, effective interest rate and annual percentage yield. Compound Interest Rate Formula takes into account the principal amount and all interest accumulated. Interest is also stated as a yearly rate and so compounding periods can also be yearly, semiannually, monthly or quarterly.

Compound can be understood by thinking of it as back to back, series of interest contracts. For example if the initial principal is Rs. 5000 and interest for the year is Rs. 50 than the principal amount rises to Rs. 5050. This is the easiest method of understanding compound interest. Compound Interest Rate Formula remains same as the simple interest formula i.e. principal*interest rate; but the value of the principal amount keeps changing every year. Compound Interest Rate Formula has been of great help for mathematicians, financial managers and consumers. This makes comparison between simple interest and compound interest easy and swift. Another major importance of Compound Interest Rate Formula is that it has highlighted and increased the importance of compounding in the world. Today, compounding is a frequently used phenomenon in almost every mathematical subject.

Compound Interest Rate Formula has not only helped consumers in their daily lives; but it has also made them independent in making their own calculations. It is easy to understand and has wide implications in financial institutions and banks. Therefore, if you are not satisfied with the calculations of your bank, you can always use Compound Interest Rate Formula to check it yourself.
