Hello !


I am trying to calculate my margins on my projects.


All my costs appear in the “Costs” box.


I would like to add up all these costs in the next cell “total costs”.


Which dormule should I write?


Then what formula should I write to subtract “TTC cell” - “Total Cost”?


Thank you very much for your help, very much appreciated 🙂



  1. Turn {Total Costs} into a Rollup-type field that uses the aggregation SUM(values)

  2. Turn {Margin} into a Formula-type field that uses the formula {Total Costs} - {TTC}
