A= P (1+r/100) ^n

A= Amount,

P= Principal,

R= Rate %,

N= no. of years.

Compound Interest = [P (1+r/100) ^ N – P]

= P [(1+r/100) ^ n – 1]

Condition:-

(1).When  interest is compounded annually,

Amount = P(1+r/100)^n

(2).When interest  is compounded half yearly,

Amount = P(1+(r/2)/100)^2n

(3).When interest is compounded Quarterly,

Amount =P(1+(r/4)/100)^4n

(4)When interest is compounded annually but time is in fraction, say 3 whole 2/5 year

Amount = P(1+r/100)^3×(1+(2r/5)/100)

(5).When Rates are different for different years, say r1%, r2%, and r3% for 1st, 2nd and 3rd year respectively.

Then,

Amount = P(1+r1/100)×(1+r2/100)×(1+r3/100).

Present worth of Rs. x due n years hence is given by:

Present Worth = x/(1+r/100)
