Best Answer

p = principal

r= rate in decimal

a =amount or final total

t = time in years

i = accumulated interest

Simple interest:

i=prt

therefore t = i/pr

Compound interest:

a=(1+r)^t

alright I'm going to throw in logs (logarithms) baby

therefore log a = log ((1+r)^t)=t x log (1+r)

therefore t = log a / log (1+r)
