That works. Thanks. I should learn calc. ;-}

I now have (I already made changes):
    |---+-------------+--------------+--------------|
    | # | Total hours | 14.00        | 6.00         |
    | ^ |             | totalTime1   | totalTime2   |
    |   | Hourly rate | 40           | 50           |
    | ^ |             | hourRate1    | hourRate2    |
    | # |  To declare | 560.00       | 300.00       |
    | ^ |             | declaration1 | declaration2 |
    |---+-------------+--------------+--------------|
    #+TBLFM: $totalTime1=deg(vsum(@-II..@-I)); f2 :: $totalTime2=deg(vsum(@-II..@-I)); f2 :: $declaration1=$totalTime1*$hourRate1; f2 :: $declaration2=$totalTime2*$hourRate2; f2

This works. One strange thing (not important I think, but I mention
it), I needed to recalculate twice. The first time the 'Total hours'
was displayed correctly, only the second time 'To declare' was
displayed correctly.

I have two formula's that I have to write for every column, I still
would like to now if there is a way to only write them once.

I am not very happy with the long line of formula's. Especially when I
have to repeat formula's. Would something like this be possible?
    #+TBLFM: $totalTime1=deg(vsum(@-II..@-I)); f2 ::
             $totalTime2=deg(vsum(@-II..@-I)); f2 ::
             $declaration1=$totalTime1*$hourRate1; f2 ::
             $declaration2=$totalTime2*$hourRate2; f2

This would at least make updating repeating formula's easier and
easier to check.
