Compound Interest Formula
The formula for calculating Compound Interest is:
Compound Interest = Amount – Principal
Where the Amount is given by
A = P(1+r/n)^{nt}
where,
A = Amount
P = Principal
R = Rate of Interest
N = Number Of Years
T = Time
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
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} |
