Compound Interest Calculator

How Does Compound Interest Differ from Simple Interest?

Compound and simple interest calculations differ in how they compute returns over time. While simple interest is calculated only on the initial principal, compound interest is calculated by combining the principal and accumulated interest from previous periods. Here is the difference between both of these financial terms:

Compound Interest	Simple Interest
Interest is earned on both the principal and previously accumulated interest.	Interest is earned only on the original principal amount.
Grows at an accelerating rate over time.	Grows at a constant rate over time.
Best suited for long-term investments like mutual funds, fixed deposits, and retirement savings.	Best suited for short-term investments like savings accounts and certain bonds.
It can increase debt quickly if interest isn’t paid regularly.	Debt grows at a steady pace, making it easier to manage.

Here is a simple way to understand the difference between both terms: imagine investing INR 300,000 in a bank for 5 years with an interest rate of 8%. With simple interest, a fixed sum of ₹24,000 would be added to the principal over 20 years. However, with compound interest, the principal grows annually as interest is added to the previous year’s balance, resulting in significantly higher returns over time.

Using their respective formulas, you can calculate that an investor earns INR 420,000 with simple interest and a massive sum of INR 440,798 using a compound interest rate.

Investing Rs.100,000 for 20 Years with Compound Interest Returns

Let us take an example to understand the concept of a cumulative interest calculator. Imagine you deposit INR 100,000 in a bank account offering compound interest rates of 6% annually for 20 years. Your compound interest is added to the principal each year, significantly boosting your overall returns.

Here is a tabular representation of the same:

Year	Interest Earned (INR)	New Principal (INR)	Total Balance (INR)
1	6,000.00	106,000.00	106,000.00
2	6,360.00	112,360.00	112,360.00
3	6,741.60	119,101.60	119,101.60
4	7,146.10	126,247.70	126,247.70
5	7,574.86	133,822.56	133,822.56
6	8,029.35	141,851.91	141,851.91
7	8,511.11	150,363.03	150,363.03
8	9,021.78	159,384.81	159,384.81
9	9,563.09	168,947.90	168,947.90
10	10,136.87	179,084.77	179,084.77
11	10,745.09	189,829.86	189,829.86
12	11,389.79	201,219.65	201,219.65
13	12,073.18	213,292.83	213,292.83
14	12,797.57	226,090.40	226,090.40
15	13,565.42	239,655.82	239,655.82
16	14,379.35	254,035.17	254,035.17
17	15,242.11	269,277.28	269,277.28
18	16,156.64	285,433.92	285,433.92
19	17,126.03	302,559.95	302,559.95
20	18,153.60	320,713.55	320,713.55

Hence, your overall returns after 20 years will be INR 320,713.55 if calculated with a compounded interest. Now, if you had invested it with a simple interest rate of 6%, each year, only INR 6000 would have been added to the principal amount. After 20 years, your investment would have grown into INR 220,000, significantly lower than the value earned via compound interest.

Dos and Don’ts of Using A Compound Interest Calculator

Here are some tips and tricks of using (and not using) a Compound Interest Calculator to maximise your utility of this tool:

Dos	Don’ts
Enter the right principal, interest rate, time, and compounding frequency.	Avoid entering very high interest rates or extremely long investment periods right at the beginning, as it might demotivate you.
Test various interest rates and periods to see how your money can grow.	Remember that rising prices can reduce the real value of your future returns, so factor in that while entering your principal amount.
Use the calculator to save for retirement, education, or other future needs.	Your actual returns may be lower after deductions, so clarify that with your desired banks.
Check multiple savings plans to find the best returns.	Don’t assume all banks calculate interest similarly, as different institutions may have different rules.
Use the calculator often and update your calculations as interest rates or goals change.	Always check your results with a financial expert before investing.
