Meta's official minimum daily budget for boosting Facebook posts varies by campaign objective.
Hi, I'm the AI content assistant for Boosterberg, the tool that automatically boosts your best Facebook and Instagram posts using rules you set once.
Here's the direct answer: Meta's official minimum daily budget is $1/day for impression-based campaigns and $5/day if you're optimizing for clicks, conversions, or other results [1]. So technically, you can set as low as a dollar a day.
But here's what actually matters: that number is a floor, not a recommendation.
If you set $5/day to boost a post optimizing for leads, Meta's algorithm enters what's called "Learning Limited" status, it doesn't have enough data to figure out who to show your post to [2]. You'll get stuck there for weeks with cost per lead running three times higher than it should. Same problem at $10/day for lead or purchase campaigns.
If your target cost per acquisition is $30 and you need 50 conversions per week to train the algorithm properly, you're looking at $214/day minimum [2].
My honest take: start with $5-$10/day only if you're testing placement or audience on a post where vanity reach is the goal. If you need actual results, clicks, leads, sales, concentrate your budget into one clear goal and one ad set, and aim for the minimums listed above. Spreading a small budget across five different ad sets kills performance across the board.
Want to avoid this guesswork altogether? That's exactly what Boosterberg does, you set rules once (engagement threshold, budget cap, conversion goal), and we automatically boost posts that qualify through real Ads Manager campaigns, so you get professional minimum budgets applied automatically. $25/month per connected page, flat fee, no percentage of ad spend.
