how to calculate compound interest?

compound interest is the “interest on interest.” unlike simple interest, it also takes into account the interest earned by the investor to date.

here is the compound interest formula –

p * (1 + i)n – p

where,

p – principal amount

i – rate of interest

n – compounding intervals

for example,

mr xy invested rs. 1,00,000 bearing an interest rate of 12% that compounds monthly. what would be his interest for the entire year?

solution:

in this case,

p – rs. 1,00,000

i – 12%/12 = 1%

n – 12 times

compound interest – ₹1,00,000 * (1 + 0.01)12 – ₹1,00,000 = ₹12,680

so, mr. xy earned 12,680 for the entire year by investing ₹10,0000.

how to use compound interest calculator online?

  • principal amount

  • compounding interval in a year

simple interest vs compound interest

there are two ways we calculate interest on the amount deposited – simple and compound.

the former is simple – you take an interest rate and multiply it with the principal amount and the time period.

compound interest is a bit complex. also known as “interest on interest,” we calculate it on the principal amount and the accumulated interest until the calculation date.

formulas for calculating interest:-

simple interest – p x i x n

compound interest – p x (1 + i)n – p

where,

p – principal amount on which interest is to be calculated

i – periodic interest rate

n – number of compounding periods

which one bears higher returns for the investor?

the answer is compound interest. compound interest builds on the principal and the accumulated interest, whereas simple interest only considers the principal amount. the more times you are getting your investment compounded, the higher returns you will get. 

advantages of using compound interest calculator

there are two ways in which we can calculate interest—simple and compound. the former calculates the interest on the principal amount. in contrast, we calculate compound interest on the principal and the interest earned on it till that date.

calculating simple interest is everyone’s cup of tea, whereas compound interest calculation can be out of your ballpark unless you are a finance guy. so, it is always a better option to use a compound interest (ci) calculator online to inform you about your accumulated interest.

what are the frequencies of calculating compound interest?

the basic idea of compound interest is that your principal gets compounded over and over again. it is simple - the lower the compounding period, the higher the interest earned.

a compound interest formula generator can help you calculate your compound interest in the following way –

frequency of compounding

periods of compounding

adjusted periodic rate

daily

365 times every year

annual interest rate (i) / 365

monthly

12 times every year

annual interest rate (i) / 12

quarterly

4 times every year

annual interest rate (i) / 4

half-yearly

2 times every year

annual interest rate (i) / 2

annually

once every year

annual interest rate (i)

understanding important terms of compound interest

principal – it is the seed, i.e., the amount that you initially deposit for compounding.

frequency of compounding - it refers to the times the plant bears fruit, i.e., it is the number of times you pay interest in a year (say monthly, quarterly, half-yearly, or annually).

how do different compounding periods affect interest?

compound interest takes into account several factors, including time horizon, compounding periods, and more. it is the reason many people resort to using a compound interest formula calculator for calculating the same.

compounding periods refer to the number of times the compounding takes into place in a given time horizon. it also impacts the applicable interest rates and other factors. 

for example,

mr. x invested ₹10,000 at an interest rate of 12% that compounds (i) monthly & (ii) quarterly. what would be his interest for the entire year in both scenarios?

 solution – 

(i) 

in this case,

p – rs. 10,000

i – 12%/12 = 1%

n – 12 times

compound interest – rs. 10,000 * (1 + 0.01)12 – rs. 10,000 = rs. 1,268

so, mr. x earned 1,268 for the entire year by investing 10,000.

(ii)

in this case,

p – rs. 10,000

i – 12%/4 = 3%

n = 4 times

compound interest – rs. 10,000 * (1 + 0.03) 4– rs. 10,000 = rs. 1,255.

so mr. x earns ₹13 more by opting for monthly compounding.

a compound interest calculator online would help you compare the different compounding periods and gauge the change in the overall interest earned.
