__Compound Interest Formulae__

Compound Interest basic terms
A = Amount

P = Principal

R = Rate of Interest

N = Number of Years

1. Interest Compounded Yearly

Amount (A) = Principal (P) X ( 1 + Rate of Interest (R) / 100 )Number of Years (N)

2. Interest Compounded Half-Yearly

Amount (A) = Principal (P) X [ 1 + Rate of Interest (R) / 2 / 100 ]2 X Number of Years (N)

(or) Principal (P) = [ 1 + Rate of Interest (R) / 200 ] 2 X Number of Years (N)

3. Interest Compounded Quarterly

Amount (A) = Principal (P) X [ 1 + Rate of Interest (R) / 4 / 100 ]

(or) Principal (P) [ 1 + Rate of Interest (R) / 400 ] 4 X Number of Years (N)
