Answer 1

Answer:

Compound Interest Formula

The compound interest formula is given below:

Compound Interest = Amount – Principal

Where the amount is given by:

Compound Interest

Where,

A= amount

P= principal

R= rate of interest

n= number of years

It is to be noted that the above formula is the general formula for the number of times the principal is compounded in an year. If the amount is compounded annually, the amount is given as-

A=P(1+R100)t

Try out: Compound Interest Calculator

Let us get to know the values of Amount and Interest in case of Compound Interest for different years-

Time (in years) Amount Interest

1 P(1+R100) PR100

2 P(1+R100)2 P(1+R100)

3 P(1+R100)3 P(1+R100)2

4 P(1+R100)4 P(1+R100)3

n P(1+R100)n P(1+R100)n

This data will be helpful in determining the interest and amount in case of compound interest easily.
