Compound Interest: A Smart Approach to Choosing the Best Investment Plan

When it is about achieving short-term financial goals, finding the best investment plan for 1 year, 3 years, and 5 years becomes critical. Not only this, but after the first year, you would want your money to compound. The thing with compound interest is that the interest you earn over time is computed and then added to your initial account balance. So, in the next compound period, your interest will be computed on the total of your principal investment plus the interest amount you previously accumulated.

You need to select an investment avenue If you want to invest your savings and earn returns over it. You can invest your money in investment options like fixed deposits, mutual funds, etc. But first, you need to understand how compounding works, as that will help you make smarter decisions. And with a reliable investment calculator, it will be even easier for you to visualize your potential returns.

What is Compound Interest?

Compound interest is the interest calculated on the principal amount as well as the interest earned from the previous period. On the other hand, simple interest is only calculated on the initial investment and doesn’t take into account the interest earned from the previous period. Compound interest accelerates growth over a period of time.

Not only this, if you are looking for the best investment plans for 1 year, you can consider plans compounding every month or every quarter.

Why Compound Interest Matters in Short-Term Investing?

While compounding is more powerful if an investment is kept for a longer tenure. But, it is equally relevant for achieving your short term goals as well. For instance, if you are looking for the best investment plans for 1 year, choosing an option that compounds frequently can help you make the most of your money in a limited period of time.

Let’s say you invest ₹1,00,000 in an investment option that offers 8% interest p.a. compounded monthly. At the end of the year, you would earn more than you would with a simple interest investment option. The difference might seem small, but when you repeat this investment process or do it at scale, it will add up significantly.

Compound Interest Formula

This formula is used to compute the compound interest of any investment option –

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

As you already know, here

  • A is the future value of your investment or maturity amount
  • P is your principal investment amount
  • r is the annual interest rate (expressed in decimal)
  • t is the number of years for which you intend to invest the money
  • n is the number of compounding periods per year

Example of Compound Interest Investment

Suppose Geeta invests Rs.10,00,000 for 1 year to earn an interest of 8.5% on her investment compounded quarterly. Let’s calculate the returns on her investment using the compound interest formula –

  • P = 1000
  • r = 8.5% = 8.5/100 = 0.85
  • t = 1
  • n = 4

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

A = 1000000(1+0.85/4)^(4*1)

A = ₹ 10,87,748

Using the formula, we can estimate that by the end of 1 year, Geeta will receive Rs. 10,87,748 as the maturity amount.
