At the moment I am using the following formula:
#+TBLFM: @<<$4..@>>$4 = $2 - $3 :: @>$2=vsum(@<<$2..@>>$2) ::
@>$3=vsum(@<<$3..@>>$3) :: @>$4=vsum(@<<$4..@>>$4)
This does what I want, but there are two things that could be improved.
- The second, third and fourth formula do exactly the same, only on
different columns. Could this be rewritten to one formula?
- The line becomes long and hard to evaluate for a person. Is there a
possibility to put the formulas below each-other?

I don't believe so but my belief may be out of date. It has been
discussed before: check the list archives.

Sort of but not really. See "Using multiple #+TBLFM lines" in the
manual.
,----
| Using multiple #+TBLFM lines
| ............................
|
| You may apply the formula temporarily. This is useful when you switch
| the formula. Place multiple ‘#+TBLFM’ lines right after the table, and
| then press ‘C-c C-c’ on the formula to apply. Here is an example:
|
| | x | y |
| |---+---|
| | 1 | |
| | 2 | |
| #+TBLFM: $2=$1*1
| #+TBLFM: $2=$1*2
|
| Pressing ‘C-c C-c’ in the line of ‘#+TBLFM: $2=$1*2’ yields:
|
| | x | y |
| |---+---|
| | 1 | 2 |
| | 2 | 4 |
| #+TBLFM: $2=$1*1
| #+TBLFM: $2=$1*2
|
| Note: If you recalculate this table (with ‘C-u C-c *’, for example), you
| will get the following result of applying only the first ‘#+TBLFM’ line.
|
| | x | y |
| |---+---|
| | 1 | 1 |
| | 2 | 2 |
| #+TBLFM: $2=$1*1
| #+TBLFM: $2=$1*2

That I found. Is handy, but only for debugging. But with the shortened
formula line, it is less of a problem.

Works like a charm. Thanks.

I should study that more diligently.
