# Overview

The **calculations** in Surface Solutions are the central tool for performing all computations for your coating projects efficiently, consistently, and transparently. They make it possible to manage offers, positions, and items in a structured way, carry out calculations automatically, and apply individual adjustments.

With the calculations, you can:

- Calculate positions with various items and individual properties
- Define complex calculation logics using templates and formulas
- Display notes and warnings for users directly in the calculation editor
- Manage items centrally and assign specific formulas to them if needed

</div></div></div></div></div></div>The calculations are modular in structure and consist of several areas:

<div class="text-base my-auto mx-auto pb-10 [--thread-content-margin:--spacing(4)] thread-sm:[--thread-content-margin:--spacing(6)] thread-lg:[--thread-content-margin:--spacing(16)] px-(--thread-content-margin)" id="bkmrk-calculation-overview"><div class="[--thread-content-max-width:40rem] thread-lg:[--thread-content-max-width:48rem] mx-auto max-w-(--thread-content-max-width) flex-1 group/turn-messages focus-visible:outline-hidden relative flex w-full min-w-0 flex-col agent-turn" tabindex="-1"><div class="flex max-w-full flex-col grow"><div class="min-h-8 text-message relative flex w-full flex-col items-end gap-2 text-start break-words whitespace-normal [.text-message+&]:mt-1" data-message-author-role="assistant" data-message-id="a872d96e-1849-4fe3-b5f2-821668025480" data-message-model-slug="gpt-5" dir="auto"><div class="flex w-full flex-col gap-1 empty:hidden first:pt-[1px]"><div class="markdown prose dark:prose-invert w-full break-words dark markdown-new-styling">1. [Calculation Overview](https://academy.surface-solutions.com/books/user-manual-en/page/calculation-overview "Calculation Overview"):   
    Displays all existing calculations in a clear overview. Here, new calculations can be created and existing ones can be viewed.
2. [Calculation Editor](https://academy.surface-solutions.com/books/user-manual-en/page/calculation-editor "Calculation Editor"):  
    Allows detailed editing of individual calculations. You can add positions, fill in fields, override calculations, and display notes.
3. [Calculation Definition](https://academy.surface-solutions.com/books/user-manual-en/page/calculation-definition "Calculation Definition"):  
    Here, you define the calculation logic, set up templates, fields, and formulas, and structure the calculation using sections. You can also manage notes and the visibility of fields.
4. [Item Database](https://academy.surface-solutions.com/books/user-manual-en/page/item-database "Item Database"):  
    Contains all items of your organization. Here, items can be created, edited, or deleted, including images, article numbers, and specific formula overrides.

</div></div></div></div></div></div>Thus, the calculations provide an **end-to-end solution** that covers everything from defining the calculation logic and managing items to creating calculations and offers.

By combining the overview, editor, definition, and item database, it is ensured that calculations can be performed **accurately**, **transparently**, and **flexibly**—regardless of how complex the items or orders are.
