1 Calculate Principal Amount, solve for P. 2  P = A / (1 + r/n) nt. 3  Calculate rate of interest in decimal, solve for r. 4  r = n[(A/P) 1/nt - 1]. 5  Calculate rate of interest in percent. 6  R = r * 100. 7  Calculate time, solve for t. 8  t = ln(A/P) / n[ln(1 + r/n)] = [ ln(A) - ln(P) ] / n[ln(1 + r/n)].
