Lifetime Budget
What is ?
A lifetime budget is the total amount you are willing to spend over the entire duration of your ad set or campaign. You set a start and end date, and Meta distributes the budget across those days to maximize results. Meta may spend more on some days and less on others based on opportunities, but total spend will not exceed your lifetime budget. It is ideal for time-limited promotions and events.
Formula
Average Daily Spend = Lifetime Budget / Number of DaysExample
You set a $1,400 lifetime budget for a 14-day Black Friday promotion. Meta averages $100/day but spends $150 on the weekend with peak shopping activity and $70 on weekdays. By day 14, total spend equals exactly $1,400, with more budget allocated to the highest-opportunity days.

Optimization Tips
- 1
Use lifetime budgets for promotions with fixed start and end dates so Meta can optimize spending across the best days.
- 2
Enable ad scheduling with lifetime budgets to only show ads during specific hours when your audience is most active.
- 3
Set your lifetime budget to at least $100 per week of campaign duration for adequate delivery data.
- 4
Avoid editing the end date or budget mid-flight as it can disrupt Meta delivery optimization and reset the learning phase.
