The target needs $66.99 per order against $22.68 of contribution, so hitting it would lose money. Either the funnel improves or the target comes down. Budget the monthly figure and let daily spend vary — hard daily caps cut off the best hours, and the learning phase needs volume to stabilise.
How the Facebook Ads Budget Calculator works
Budget the monthly figure and let daily spend vary. Hard daily caps cut off the best-performing hours, and the learning phase needs conversion volume to stabilise — starving a campaign is one of the more reliable ways to make it perform badly.

Frequently asked questions
What is the minimum viable Meta budget?
Enough to produce around fifty conversions a week per ad set for the algorithm to exit the learning phase. At a £30 cost per acquisition that is roughly £1,500 a week, which is why small budgets underperform structurally.
Should I use daily or lifetime budgets?
Lifetime for fixed-duration campaigns where pacing across days helps; daily for always-on. Either way, avoid frequent changes — every significant edit restarts learning.
How fast can I scale spend?
Increases of 20% every few days are the common guidance, because larger jumps reset learning. Duplicating into a new campaign at a higher budget is the alternative, at the cost of starting learning again.
Why did my costs rise after I increased budget?
Because the algorithm reaches further into the audience for the extra volume. That is expected, and it is why the break-even ceiling matters more than the historical average.
