A coaching or consulting business new to Meta Ads should start with $500 to $1,000 per month. This gives the algorithm enough volume to optimize over 30 days and generates enough data to see what is actually working. Below $300 per month, the data comes in too slowly and the results in the first month rarely reflect what the campaign would do with a reasonable budget.
What follows are actual numbers from campaigns I've run, not ranges from a marketing blog: what each budget tier from under $300 to $2,000+ actually gets you, what $500 a month looks like in leads and calls, and when to know it's time to scale.
