I will try to answer
KjSaif:
ok @Reynelle
KjSaif:
just googled and found this....
KjSaif:
Calculate Total Amount Accrued (Principal + Interest)
A = P(1 + rt)
Calculate Principal Amount, solve for P
P = A / (1 + rt)
Calculate rate of interest in decimal, solve for r
r = (1/t)(A/P - 1)
Calculate rate of interest in percent
R = r * 100
Calculate time, solve for t
t = (1/r)(A/P - 1)
