Budgeting
You can apply extra costs to an account and set how many units of each cost this person needs.
You add extra costs such as flights, hotel nights and per diems to an account and set how many units of each the person budgeted on the account needs. You need at least one account selected in Budgeting.
In the account details of the selected account, click  **Edit extra costs** in the **Extra Costs** panel. If the account has no extra costs yet, you can also click the panel's heading **Extra Costs**. KOSMA opens the dialog for this account.
Under **Extra Costs Groups**, expand a group and tick each cost this person incurs.  **Expand all** and  **Collapse all** open or close every group. When you tick or untick a group, KOSMA ticks or unticks every cost in it. For each ticked row, **Total** shows **Value** times **Factor**.
When you point at **Value**, KOSMA shows where it comes from:
The value of this extra cost is set in extra costs settings
KOSMA lists only the costs that are not hidden in the settings. If a cost is missing or its value is wrong, click  **Settings**. KOSMA opens the **Extra Costs** settings on top of this dialog. When you close them, the dialog lists the updated definitions. See [define extra costs](/kb/article/define-extra-costs).
If this person needs more or fewer units than the definition covers, enter the number in **Factor**. **Factor** starts at 1. For example, the definition Hotel covers one night at 95.00 EUR, and this person stays 35 nights. Set **Factor** to 35. KOSMA shows 3,325.00 EUR in **Total**. When you untick a row, KOSMA removes its factor.
In **Factor**, you can enter a formula instead of a number, see [what the factor does](/kb/article/what-the-factor-does). To see the formulas instead of their results, click  **Show/hide expressions**. Click it again to see the values.
Click **Ok**. KOSMA saves the extra costs on this account. To discard everything you changed in the dialog, click **Cancel** or close the dialog.
To remove every extra cost from this account, click **Reset**. KOSMA removes them without asking. Until you click **Ok**, **Cancel** restores them.
If several accounts get the same extra costs, for example a crew on location, save the combination once as a preset. In the dialog, open **Select Preset...** and choose **Save as Preset**. KOSMA saves the ticked costs and their factors. To apply the preset to another account, open that account's dialog, open **Select Preset...** and choose the preset. KOSMA replaces the extra costs on that account with those of the preset. Extra costs have their own list of up to ten presets. Fringe and supplement presets don't appear in it. To name and edit presets, see [save and reuse a fringe preset](/kb/article/save-and-reuse-a-fringe-preset).
You can also apply a preset without opening the dialog. When a preset exists and you can edit the account, the **Extra Costs** panel shows  **Apply Preset**. Click it and tick a preset under **Extra Cost Presets**. KOSMA applies it to the account.
With a subaccount selected, KOSMA greys out the **Extra Costs** panel. Select the account itself.
You can edit several accounts together if none of them has extra costs yet, or if all of them have the same extra costs with the same factors. Select the accounts and click  **Edit extra costs**. KOSMA opens the dialog for the account you selected first. Because the accounts match, what you see applies to all of them. At the top, the dialog shows:
Applies to {rows} rows.
Work through steps 2 and 3 and click **Ok**. Every selected account now has the extra costs and factors from the dialog. If a selected account changed while the dialog was open, for example in a second KOSMA window, it stays as it is and KOSMA shows:
{number} of the selected rows changed while the dialog was open and were left as they were.
With several accounts selected, the panel offers no presets. If the selected accounts differ, for example in a cost or a factor, the panel shows:
Mixed contents · Click ↺ to reset
**Edit extra costs** is then unavailable. To edit them together, first remove their extra costs.
**Reset extra costs** removes every extra cost from all selected accounts.
Click  **Reset extra costs** and confirm. Unlike **Reset** in the dialog, it asks first.
