How Much Should You Spend on Social Ads? A Simple Budget Framework

"As much as we can afford" isn't a budget — it's an absence of one. A real ad budget starts from a goal (leads, sales, signups) and works backward through your numbers, not from a leftover line item in a marketing spreadsheet.

Start from the goal, not the spend

Decide what you're actually trying to buy — 100 trial signups, 50 leads, a certain number of sales — before deciding how much to spend. Spend-first budgeting tends to produce vague results because there was never a target it was measured against.

Work backward through your funnel math

If a customer is worth $80 and your historical cost-per-acquisition runs around $20, that's a 4x return per dollar spent — a number you can scale a budget against. Without knowing your own cost-per-acquisition and customer value, any ad budget is a guess dressed up as a number.

New accounts need a testing budget, not a scaling budget

The first weeks of any ad account are about learning what works — which creative, which audience, which placement. Budget for testing separately from budget for scaling; treating early spend as if it should already be efficient leads to premature conclusions about what's "working."

The 70/20/10 rough split

A reasonable starting allocation: roughly 70% to proven, working campaigns, 20% to scaling something promising but not yet fully validated, and 10% to genuinely new tests. This keeps spend mostly anchored to what's working while leaving room to find the next thing that does.

Revisit monthly, not quarterly

Social ad platforms change fast — costs shift, audiences fatigue, creative wears out. A budget set once a quarter and left alone tends to keep funding what used to work rather than what's working now. Monthly review catches the drift before it gets expensive.
