Oops, I did misunderstand. I think this is what you wanted:

|---+------+-------+-------+-------+-------+---|
| ! | Jahr | Menge | Preis |  BIPn |  BIPr | W |
|---+------+-------+-------+-------+-------+---|
| # |    1 |    10 |   2.8 | 28.00 |     0 |   |
| # |    2 |    12 |   0.7 |  8.40 | 33.60 |   |
| # |    3 |     4 |  4.00 | 16.00 |  2.80 |   |
|---+------+-------+-------+-------+-------+---|
| _ |      |       |       |  suma |  sumb |   |
|   |      |       |       | 52.40 |  36.4 |   |
#+TBLFM: $6=$3*@-1$4;%.2f::@2$6=0::$sumb=vsum(@II..@III)

Here I add a formula to set the first row to 0.

Yours,
Christian
