# What are calculation rules in Capitech?

Calculation rules determine how Capitech calculates hours, overtime, compensation, breaks, rounding, and which dates registrations are assigned to. Changes can affect the payroll basis, so you must always submit a support request to have a calculation rule changed.

## What does this cover?

Calculation rules are the settings that determine how registered hours are interpreted in Capitech.

This may include:

-   regular hours
-   overtime
-   compensation
-   break deductions
-   rounding
-   how hours are allocated to dates

These settings form the basis for how hours are calculated throughout the system. Small changes can therefore have significant effects.

## Why are employee groups important?

In most cases, calculation rules in Capitech are based on **employee groups**.

This means that an employee’s group often determines which calculation logic applies to them. For example, you may have separate groups for salaried employees who do not receive overtime or for employees covered by different collective agreements.

Employee groups are therefore often an important part of how hours, overtime, and compensation are calculated.

## When is this relevant to you?

This article is relevant if you:

## How to get started

If you want to change or review calculation rules, you must submit a support request to [support@capitech.no](mailto:support@capitech.no).

Briefly describe:

-   what you want to achieve
-   which employees or employee groups it applies to
-   the date from which the change should apply

## Important information

Calculating hours often affects:

-   payroll
-   compensation

-   balances
-   reporting

If a rule is configured incorrectly, hours may be interpreted incorrectly and, in the worst case, employees may receive incorrect pay. We therefore always recommend contacting us before any changes are made.
