# Ad budgets

> Set a monthly cap on ad spending per brand, see how much is committed, and split one total over every brand.

Each brand runs its own ad campaigns. On **Ad budgets**, head office sets how
much each brand may commit per month. Lethra stops a brand from committing
more than that.

(Screenshot: The Ad budgets page: total caps, committed this month and room left, a cap per brand with a progress bar, and the Split a total budget form.)

## What counts as committed

A campaign commits its daily budget for every day of the month. A campaign of
€10 a day in a 31-day month commits €310. Campaigns that are live or in
review count. Drafts, and campaigns that are approved but not live yet,
paused or completed, do not.

This is what a brand has signed up to spend, not what has been spent so far.

## Setting a cap

Type an amount in euros next to a brand, then press Enter or click elsewhere.
The cap is saved straight away.

- **A cap carries over.** It applies to this month and every month after,
  until you change it. "Since September 2026" under a brand means the cap was set
  then and still applies.
- **Changes start this month.** Earlier months are not touched.
- **No cap.** Clear the field, or click the cross next to it. The brand can
  then commit any amount, from this month on.

## What happens at the cap

When a brand tries to put a campaign live, send it for review, or raise its
daily budget, Lethra adds it to what the brand has already committed. If the
total would go over the cap, the change is refused. Lowering a daily budget is
always allowed.

A brand can still end up above its cap, for example when you lower a cap below
what is already committed. Nothing is stopped in that case. The brand shows
**Above cap** and appears on the overview under **Needs attention**.

## Reading the page

The four numbers at the top are the total of all caps, what is committed this
month, the room left under the caps, and how many brands have a cap.

Each brand shows its committed amount, a bar against its cap, the number of
live campaigns, and one of four states:

- **No cap**
- **Within cap**
- **Close to cap**: 85% of the cap or more
- **Above cap**

## Split a total budget

To divide one monthly amount over every brand, enter it under **Split a total
budget** and click **Split evenly**. Each brand gets the same amount in whole
euros. If the amount does not divide evenly, the first brands get one euro
more. Then fine-tune individual brands.

Splitting replaces the cap of every brand, including brands that had none. The
form only appears when the group has two brands or more.
