How to plan an ad budget properly
Most budgets are set by picking a number that feels affordable and hoping. Working backwards from the target is more useful: it tells you immediately whether the goal is reachable at your current conversion rate and CPC, or whether something has to change first.
- Budget = (goal ÷ AOV) ÷ conversion rate × CPC. Every input is one you can measure today, so the output is checkable rather than aspirational.
- Check the implied ROAS before committing. If the plan needs a ROAS below your break-even, the budget is not the problem — the funnel is.
- CPC rises as you scale. Doubling spend rarely doubles conversions at the same cost. Assume a 10–30% CPC increase when planning a step up.
- Give the algorithm room. Smart Bidding and Advantage+ need roughly 30–50 conversions a month to leave the learning phase. A budget that cannot reach that will underperform regardless of targeting.
- Plan monthly, watch weekly. Daily budgets fluctuate by design — platforms overspend on high-intent days. Judge pacing on the month.
