###### Tip For You

Invest early. The longer your money has time to work for you, the more significant the effect of compounding can be. Compounding is known as the eighth wonder of the world!

## Introduction

The main purpose of any type of savings is either earning regular returns or gradually building a corpus fund that can be used to meet the long-term financial goals. The returns generated on any investment can be in the form of dividends or interest that may be received at fixed intervals or reinvested in the investment fund to generate more returns.

When the investor reinvests the interest income, they are essentially earning more returns on their income already earned. This is the basic premise of compounding where money generates more money. Compounding is the easiest and the fastest way to build a corpus fund. Most dynamic investment products rely on the concept of compounding to maximize investor’s wealth. Compound interest is calculated at many intervals like daily compounding, monthly compounding, quarterly compounding, half-yearly compounding, and yearly compounding.

However, it may often be difficult for an average investor to calculate the exact fund value to be received upon maturity based on such compound interest investing. This is where a compound interest calculator can be quite helpful.

Given below are a few details of the compound interest calculator and the need for the same.

### What is a compound interest calculator?

A compound interest calculator is a simulation or a financial tool that can be used to calculate the compounded interest and the accumulated wealth at the end of the tenure at the specified rate of interest. This mathematical tool drastically reduces the efforts of the investors to calculate the accumulated amount at the end of the tenure for any investment. It also helps them work out many permutations and combinations of the amount to be invested to meet their target financial goals. This tool is available on the website of lenders or other portals that assist in making sound investments on behalf of the investors.

### How does a compound interest calculator work?

We have discussed the meaning of the compound interest above. Let us now understand how it works. For this, we can take a basic example of an investment of Rs. 1,00,000 which is invested for 5 years at an annual compounded interest rate of 10%. The amount of interest and the final value of the investment value is shown in the table below.

Year | Amount invested at the start of the year | Interest rate | Interest amount | Investment value at end of the year |
---|---|---|---|---|

1 | 100000 | 10% | 10000 | 110000 |

2 | 110000 | 10% | 11000 | 121000 |

3 | 121000 | 10% | 12100 | 133100 |

4 | 133100 | 10% | 13310 | 146410 |

5 | 146410 | 10% | 14641 | 161051 |

Total | 61051 |

From the above example, we can see that the investor has earned net earnings of Rs. 61,051 on the initial investment of Rs. 1,00,000.

The above example was quite basic but in the real world, these calculations can run into pages when the investment is long-term and the compounding factor is daily or monthly. It can become quite cumbersome for the investors to calculate the compounded value of an investment in such cases.

Compound interest calculators can be a huge help in such cases. Investors have to simply provide certain basic inputs in such calculators to get the final value of the investment at the end of the tenure.

### Formula for Compound Interest Calculation

As mentioned above, a compound interest calculator
requires the investors to provide few basic parameters for
getting the final fund value. The basic formula to calculate the
compounded interest is,

A = P(1+r/n) ^ nt

Where

- A = Final amount at the end of the term
- P = Principal amount or initial investment
- r = compounding rate of interest
- n = compounding frequency per year
- t = number of years in the tenure

If we consider the above example again, the final amount will be derived in the following manner.

A = 100000(1+0.10/1)^1*5

A = Rs. 1,61,051

The amount of
interest earned over the years is Rs. 61,051.

### How to use Finity compound interest calculator?
