Budget & Pacing

Accelerated Delivery vs Lifetime Budget for Short Flights

In short: Only one of these still exists. Accelerated delivery was pacing that spent as fast as auctions allowed, and it has been removed from mainstream Google and Meta campaign setup. A lifetime budget is a live setting: a total paced across a scheduled window. For short flights, the lifetime budget plus a tight schedule now does the job accelerated used to.

Accelerated Delivery

Legacy pacing option that spent the budget as fast as auctions allowed instead of spreading it across the day.

Google removed it from Search, Shopping, and Display campaigns, and Meta dropped it from ordinary ad set setup, so standard pacing is effectively what you get today. It was used to front-load spend on short flights or to test whether the budget was the limiting factor. Anyone still asking for it wants faster delivery, which now comes from raising budgets, loosening targets, or widening targeting.

Lifetime Budget

A total amount spent across a campaign or ad set's entire scheduled run, paced by the platform over that whole window.

You set the pot and the end date, and delivery is paced across the flight instead of resetting each day. On Meta it is the prerequisite for ad scheduling, so any dayparting requires it. It fits fixed promotions and hard-capped budgets. The constraint people hit is editing: shortening the schedule or raising the amount mid-flight resets pacing and can push the ad set back into learning.

What actually separates them.

01

One is a retired pacing mode and the other is a live budgeting decision, so they were never really alternatives.

02

Accelerated changed how quickly a budget drained; a lifetime budget changes how much there is and over what window.

03

The modern way to concentrate delivery is a shorter flight plus a schedule, not a faster pacing mode.

04

Standard pacing applies to lifetime budgets automatically, spreading the total across the flight rather than front-loading it.

Which one should you use?

Use Accelerated Delivery when

  • You are reading an old guide or inherited account note and need to know what replaced it.
  • A launch or flash sale has to deliver inside hours and you want the current mechanism.
  • Delivery is slower than expected and you want to rule pacing out as the cause.
  • You are auditing a structure originally built around front-loaded spending.

Use Lifetime Budget when

  • A promotion has a hard total and a fixed end date you cannot exceed.
  • You need dayparting on Meta, which is unavailable without a lifetime budget.
  • The budget was approved as a pot for a window rather than a monthly rate.
  • You want delivery weighted toward the strongest days inside the flight.

Common questions.

What replaced accelerated delivery for short campaigns?

A lifetime budget with a tight window and, where relevant, an ad schedule. Concentrating the same total into fewer days or hours produces the front-loading people used accelerated for, without the failure mode of exhausting the budget before the day's better auctions. Loosening bid targets adds further headroom if delivery still lags.

Does a lifetime budget spend faster than a daily budget?

Not inherently. It spends the total across the window you set, so a short window means a higher effective daily rate and a long one means a lower rate. The speed comes from the length of the flight relative to the amount, not from any difference in how pacing works.

Can I front-load a lifetime budget deliberately?

Only by shaping the flight. Shorten the window, or split the campaign so an early flight carries a larger share of the total, and use an ad schedule to confine delivery to chosen hours. There is no setting that tells the platform to spend aggressively now and slowly later within one flight.

Or stop choosing between them.
