Facebook ads budget: daily vs lifetime, and how Meta spends it

Both work for campaign budgets and ad set budgets:

Meta's daily budget page explains the limits with a $100 daily budget as the example:

• On a good day, Meta may spend up to 75% over your daily budget: up to $175. Some days it spends less.
• Across a week ending Saturday at midnight, it won't spend more than 7 times your daily budget: $700.
• With ad set budget sharing on, up to 20% of the daily budget can move to other ad sets, so a day can reach $210 and a week $840.
• If an ad set starts mid-week, or you change the budget mid-week, the limit for the rest of the week is prorated plus up to 25% of the daily budget.
• Meta says it will consider refunds for spend above 1.75 times the daily budget in a day or 7 times it in a week.

Campaign budgets all use Advantage+ campaign budget: one budget that Meta moves in real time to the ad sets with the best opportunities. Meta says this works best if you're flexible about how spend splits across ad sets.

Ad set budgets give you more control over each ad set, which helps when ad sets have different optimisation goals, bid strategies or very different audience sizes. Ad set budget sharing can't be used with campaign budgets.

You need admin access to the ad account. In Ads Manager:

1. Hover over the campaign (for a campaign budget) or the ad set (for an ad set budget).
2. Click Edit.
3. Change the budget.
4. Click Publish. Meta says the new budget takes about 15 minutes to apply.

• Minimums vary by country, objective and settings, and Ads Manager shows an alert if you're below them. They're calculated per day, so a five-day lifetime budget must be at least five times the daily minimum.
• With a cost per result goal, Meta suggests a daily budget of at least 5 times the goal.
• When lowering a lifetime budget, keep it at or above what you've spent so far plus 10% of the last two days' spend.

Meta's explanations:

• Accelerated delivery spends as fast as possible, sometimes in under an hour. Switch to standard delivery.
• The ad set was in the learning phase, when Meta may deliver more aggressively.
• Your budget is close to or below your bid. Meta says the budget should be higher than the bid.
• Ads paused with budget left: you may have hit your account's daily spending limit, which Meta sets.
• Unpausing straight after a budget change can deliver on the old budget for about 15 minutes, so wait before unpausing.
• A bill after pausing covers spend from before the ad stopped; it doesn't mean the ad restarted.
