How Much Should I Spend on Meta Ads?

The Short Answer

Start at $20/day per ad set — Meta's practical minimum for gathering 50 conversion events per week to exit the learning phase. For most businesses, that means $1,500-3,000/month across 2-3 ad sets. Spend less and Meta can't optimize, keeping your CPA elevated. Tie budget to your target CPA: if leads cost $30, budget at least $210/week per ad set.

Budget Stages and Scaling Rules

Testing phase ($1,500-3,000/mo): Run 2-3 ad sets testing different audiences or creatives to find winners. Scaling phase ($3,000-10,000/mo): Increase proven ad set budgets by 20% every 3-4 days. Larger jumps reset the learning phase and spike CPAs 20-40%. Mature phase ($10,000+/mo): Use CBO to let Meta allocate across ad sets. Creative refresh cadence matters more than budget increases at this stage.
