A daily budget is the amount you tell Meta it may spend on a campaign or ad set each day. In Meta ads it works as a target, not a hard daily cap: Meta's help page says that when you set a daily budget you are "setting a daily spending target over the course of a calendar week."
How much Meta can actually spend
Meta spends more on days with better opportunities and less on others. Its help page sets three limits:
- On days when better advertising opportunities are available, Meta "may spend up to 75% over your daily budget."
- For every day ending at midnight, spending "won't be more than 175% of your daily budget."
- For every week ending Saturday at midnight, spending "won't be more than 7 times your daily budget."
So the weekly total stays at or below 7 times the daily figure, while any single day can run well above it. If you set $40, a day can reach $70 (175% of $40), and the week cannot pass $280 (7 × $40).

| Daily budget | Lifetime budget | |
|---|---|---|
| What you set | A spending target per day | A total for the whole run of the campaign or ad set |
| Meta's wording | A target over a calendar week | The amount you are willing to spend "over the entire run-time" |
| Best for | Always-on campaigns | Promotions with a fixed window and a fixed total |
| Where it can sit | Campaign or ad set | Campaign or ad set |
Both budget types can sit on the campaign with Advantage+ campaign budget, or on individual ad sets.
Choosing a daily budget
- Start from the cost of one result. Take the cost per result you can afford and multiply it by the results you want each day. A $20 result and 5 results a day points to $100.
- Leave room for learning. Ad sets need results to leave Meta's learning phase, so a budget that buys only a couple of results a day makes every test slow.
- Change in steps. Big jumps make the next few days hard to read. Raise or lower the budget in small steps and wait before judging.
- Check against your margins. The ad budget calculator is a free tool that sizes a budget from your goal and costs.
Example. A dental clinic sets a $40 daily budget on a lead campaign to book new-patient visits. On Tuesday Meta finds many people ready to enquire and spends $66, which is inside the $70 day limit. Over the rest of the week it spends less, and the week closes at $262, under the $280 ceiling. The average of $37.43 a day is close to the $40 target, which is how the budget is meant to behave. A clinic that needs exactly $40 every day should not expect that from a daily budget, because Meta treats it as a weekly target.

FAQ
Can Meta spend more than my daily budget?
Yes. On days with better opportunities Meta may spend up to 75% over your daily budget, and a single day will not pass 175%. Over a week ending Saturday at midnight, spending stays at or below 7 times the daily budget.
Is a daily budget the same as ad spend?
No. The budget is what you allow, and ad spend is what Meta actually charged. Spend can sit above or below the daily figure on any given day.
Should I use a daily or lifetime budget?
Use a daily budget for campaigns that run continuously and a lifetime budget for a promotion with a fixed window and a fixed total. Meta's lifetime budget page describes it as the total you are willing to spend over the entire run.
How do I raise a daily budget safely?
Raise it in modest steps and wait a few days before the next one. Big jumps make results harder to read, and the weekly ceiling of 7 times the daily budget moves up with every change.
