Formula for Interest Compounded Yearly

Total Amount = P(1+(R/100))n

Formula for Interest Compounded Half Yearly

Total Amount = P(1+(R/200))2n

Formula for Interest Compounded Quarterly

Total Amount = P(1 + (R/400))4n

SI [Interest] = (P × R × T) / 100

P [sum] = (SI × 100) / (R × T)

R [Rate/year] = (SI × 100) / (P × T)

T [Time] = (SI × 100) / (P × R)

Where,

C.I = Compound Interest,

S.I = Simple Interest

P = Principle or Sum of amount

n = Time Span in years

R = % Rate per annum

T = Time Span
