Budgeting
You know where the factor is, what it multiplies in a supplement and in an extra cost, and which number or formula to enter.
The **Factor** adjusts a supplement or an extra cost for one account. The supplement's or extra cost's definition in Settings sets the standard for the whole budget. The factor multiplies that standard for this account. The factor does not change the definition or any other account. To change the standard for every account, edit the definition.
The **Factor** column is on the **Supplements** tab of the dialog **Fringes & Supplements: {account}** and in the dialog **Extra Costs: {account}**. The **Fringes** tab has no factor. You open the dialogs in the account details with  **Edit fringes & supplements** and  **Edit extra costs**.
The **X** column in the budget grid is a different factor. It is part of the account's own total. See [how an account total is calculated](/kb/article/how-an-account-total-is-calculated).
| Dialog | The definition sets | The factor multiplies | | ----------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------- | | **Supplements** tab of **Fringes & Supplements: {account}** | the share of working time the supplement covers, shown in **Percentage Of Work Time**, for example 10% overtime | that share. With `2`, this account runs at 20% overtime | | **Extra Costs: {account}** | an amount and a quantity. **Value** shows their product, for example one hotel night at 95.00 EUR | **Value**. **Total** shows **Value** × **Factor** |
Enter the factor that fits the account:
- This account runs at twice the standard overtime: enter `2`. - The standard is one hotel night and this account needs 35 nights: enter `35`. - The account matches the standard: enter `1`, or leave the field empty. KOSMA counts an empty factor as 1.
The factor is not a percentage. If you enter `20` on a supplement and mean twenty per cent, KOSMA multiplies the share by 20. KOSMA shows no error.
On the **Supplements** tab, KOSMA deletes the factor of a row when you untick it.
In both dialogs, **Factor** also accepts a formula. KOSMA then calculates the factor from other budget values. A formula can use the work-phase variables, your own variables and the subtotal `DFFF`. Only on the **Supplements** tab can it also use the net production costs, `NPC`. No factor formula can use the grand total `GT` or a function such as `SUM_COMPANY`.
In the demo project, the budget Demo Feature has a *Hotel* row on account 3.01 Director with this factor:
`Shooting_TD` holds the total days of the shooting phase, 35. KOSMA multiplies the 95.00 EUR of one hotel night by 35, and **Total** shows 3,325.00 EUR. When the days of the phase change, KOSMA recalculates the row.
A preset saves the ticked rows for reuse on other accounts, along with their factors. See [apply fringes and supplements](/kb/article/apply-fringes-and-supplements) and [apply extra costs](/kb/article/apply-extra-costs).
