Work backwards from a monthly ad-sales goal to the daily budget it actually requires — using your conversion rate and CPC.
Sales goal ÷ average order value = orders needed. Orders ÷ conversion rate = clicks needed. Clicks × CPC = budget. The implied ACOS this produces — CPC ÷ (CVR × AOV) — tells you whether the plan is even profitable: compare it against your break-even ACOS before committing the spend.
Two honest caveats: budgets buy clicks, not orders — short-term variance is real — and scaling spend usually nudges CPC up as you chase more competitive auctions. Treat the output as a planning floor, not a guarantee, and re-check against actuals after two weeks of mature data (attribution lag makes the first days look worse than they are).
