# Raise budgets that run out

> Find campaigns that spend their whole daily budget and raise it, but only when their results justify the extra spend.

Some campaigns could spend more than you let them. They run out of budget before the day is over, so
demand you have already paid to create goes unserved. This automation finds those campaigns and
raises their daily budget.

It only ever raises. If you want budgets to come down again when demand falls, use
[Raise and lower budgets](/docs/automations/scale-budgets-up-and-down) instead.

## How it decides

The automation works from **how much of its budget a campaign spends**: what it actually spent over
a window, compared with what its daily budget allowed across that window. A campaign with a 10 euro
daily budget that spent 70 euro over 7 days has spent 100% of its budget. One that spent 49 euro has
spent 70%.

That is measured over a window you pick: 2, 3, 7, 14 or 30 days. A campaign qualifies when it has
spent **at least** the figure you set over that window. A short window reacts to a budget running
out this week. A long one ignores a single busy day. The window ends yesterday, because today's spend
is still coming in and would make every campaign look like it spent less than it did.

A campaign that qualifies then has to meet your performance checks before anything is suggested:

- **Minimum conversions** is the volume you want before you trust the numbers. Set it to 0 to skip it.
- **Performance check** picks how you judge results: **ROAS**, **CPA** or no check at all. Only the
  target for the check you pick is shown. ROAS is a percentage, so 300% means the campaign has to
  bring in three times what it spends. CPA is an amount in the account currency.

Results are judged over the last 30 days whatever window you pick, since a conversion count or a CPA
over a few days says very little.

A campaign with spend and no conversions has no cost per conversion and no ROAS. It fails those
checks rather than passing them. This is deliberate: a missing number is not evidence of good
results.

## How much it raises

The increase is a percentage of the current daily budget, then clamped between a minimum and a
maximum amount in the account currency.

The clamps are what make the percentage safe across a mixed account. On a 5 euro budget a 10%
increase is 50 cents, which is not worth a change, so the minimum lifts it. On a 2,000 euro budget
the same 10% is 200 euro, which is a bigger jump than you probably want in one run, so the maximum
holds it back.

## Settings

**Filters** restricts the automation to campaigns carrying a campaign label. Leave it empty to
include every campaign.

**Thresholds** holds the budget-spent figure with its window, minimum conversions and the
performance check.

**Actions** holds how much each raise adds and its smallest and largest amounts.

## Suggested approach

Every run changes budgets in Google Ads, a run by hand included, so start with conservative
settings: a small raise and a low largest amount. Budgets are the setting where an automation you
have not checked costs the most.

Read the first few runs. The reason column tells you how much of its budget each campaign spent over
the window, so you can see whether the threshold matches how you would have judged the account
yourself.

Once it is running, remember that each run measures spend against the budget it raised last time. A
campaign with genuine unmet demand climbs over several runs rather than jumping in one, which is the
intended behaviour.
