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.

to get better returns as compared to simple interest options.
This helps them achieve their investment targets faster and
