# Set up calculation

In construction projects, quantities are often calculated based on specific settings. In Project Control Suite, this setup is done in calculation groups.

Use calculation groups to define:

- The formulas that are used to calculate the estimate line quantities for activities in the work breakdown structure.
- The models with the default formulas for each transaction type.
- The setup that is required for progress billing: a variable that is marked as scheduled unit. For progress billing, usually, the scheduled unit variable is a percentage.
- The setup that is required for subcontracting: a variable that is marked as scheduled unit and for which the unit is defined as well. Reason: Subcontracting uses purchase orders, and on the purchase lines a unit is required.
- A cost price (expense) or sales price (expense) for a specific scheduled unit.
