Daily vs. lifetime budget in ChatGPT Ads: which one, when?

Every ChatGPT campaign starts with one fundamental choice: a daily budget or a lifetime budget. Both cap your spend — but in very different ways. Here's how to decide.

The difference in one line

• Lifetime budget: a cap for the entire run of the campaign.
• Daily budget: a cap per day that resets every day.

Important: you pick exactly ONE per campaign — you can't combine a daily and a lifetime budget.

When to use a daily budget

• For always-on campaigns with no fixed end date.
• For testing new ads with predictable, even daily spend.
• When you want to cap what you spend per day rather than over the whole run.

When to use a lifetime budget

• For time-boxed pushes: a product launch, a sale, an event.
• When you have a fixed total to spend across the campaign's run.
• Paired with a start and end date for a clear campaign window.

Good to know

• The daily budget has a minimum of 15 per day (in your account currency).
• A daily budget doesn't get exhausted over time — it starts fresh each day.
• Both caps are per campaign. Eligible accounts also have a separate, account-wide daily cap across all campaigns.
