If you invest 70000 at 12 return what is it worth in 15 years?

The answer depends on how the interest is compounded - but in simple interest compounded annually on $70,000 at 12 percent, the total value would be $383,150. The first year the investment would earn $8,400 ($70,000 x .12), and the "principle balance" would increase to $78,400. The second year interest would be earned on $78,400 ($70,000 + $8,400 earned in year one), which would be $9,408 ($78,400 x .12), making the new principle balance $87,808. Interest in the fifteenth year would be $41,052 paid on a principle balance of $342,098, for a total of $383,150.
