For an exact computation of a joinery structure, beside material costs, should be calculate also some additional costs that a company has: leasings, factory expenses (electricity, rent, etc.), employees expenses (salaries, taxes), tehnological manufacturing losses, etc. All these costs may be entered to Ra Workshop application as Extra Costs.

The extra costs dialogue is accessed through Materials » Extra
Costs menu as seen from the picture below:
Extra Costs Dialog
Extra Costs dialog allows the following operations: add, change,
delete, copy / paste, print, export. For each facility access the
corresponding button on the toolbar.
Extra costs can belong to one of the following types:
- Materials. Extra costs will be aplied only on materials: quantities and prices to obtain a base price called Sell Value (Sv).
- Project. Extra costs will be applied on project for client price offer.
- Component. Extra costs will be applied on component for client price offer.
- Delear. Extra cost will be applied to calculate dealer offer.
Each extra costs has one ore more costs attached to it that will be applied in cost computation process. Costs can belong to one of the following types:
- Quantity Loss. Is available only for material extra cost type and will be applied to quantity.
- Production. Is available only for material extra cost type and will be applied to material value. Together with Quantity Loss cost type will compute Production Cost (PC) based on materials quantites and prices.
- Addition.
- Installation. Also an addition extra costa that will be applied separately.
- Transport. Also an addition extra costa that will be applied separately.
- Discount. Discount extra cost that will be aplied in the end.
The following formulas and parammeters are used to compute a jonery structure final price:
- Net Quantity (Nq)
- Sum of all quatities computed by our application for all project's components. (i.e. how much profile is needed for designed components). The value doesn't contains any losses.
- Gross Quantity (Gq)
- Gross quantity needed for completed the project. Contains all technological process losses.
- Gq = Nq + Nq*EC_QL, where EC_QL are all extra costs of quantity loss type.
- Unit Production Price (Pp)
- Price per measure (i.e. profile's price).
- Materials costs (Mc)
- Sum of all meterials used for a component or project.
- Mc = Nq * Pp
- Production Cost (Pc)
- Project's production cost: materials cost plus quantity losses and production costs.
- Pc = Mc + Mc*EC_P, where EC_P are extra costs of production type.
- Sell Value (Sv)
- Project's sales price: cost of material in final offer (i.e. effective amount that a client should pay for profiles).
- SV_ND = Pc + Mc*(EC_P + EC_A), SV_ND is the value of final offer with no discount and EC_A are extra costs of addition type.
- Sv = SV_ND - SV_ND*EC_D, EC_D are extra costs of discount type (discount is applied in the end of price computation process).
Add Extra Costs
To add a new extra cost click on the first registration (where it
says: "Click here to enter a new record") and complete the
following fields:
- Name. (required) Name of new extra cost.
- Description. Description of the new extra cost.
- Type. (required) Select a type for the extra cost.
