Cost Cap
01 Definition
Cost Cap meaning: A Meta bidding control that aims to keep your average cost per result at or below a set amount.
Cost Cap is a Meta Ads bid strategy where you set the highest average cost per result you want to pay. The system bids to maximize results while keeping the average near or under your cap. Individual results may cost more or less, since the cap is an average, not a hard limit.
Why it matters
How Cost Cap fits the work
Cost Cap balances volume and efficiency, letting advertisers scale results while holding the average cost within a planned target.
In context
With a Cost Cap of 20 dollars per purchase, Meta drove 50 sales at an average cost of 19 dollars each.
Practical note
Because the cap controls an average, some results exceed it. Setting the cap too low can limit delivery, and costs may rise as you scale spend.
