ACOS vs Profit on Ad Spend
ACOS = ad spend ÷ ad sales. It is revenue-based and ignores COGS and fulfillment. Profit on Ad Spend answers whether ad-attributed units actually earn after all variable costs.
Hybrid merchants advertising Amazon and DTC should not compare ACOS to DTC Return on Ad Spend — use Profit on Ad Spend on each channel with consistent cost rules.
FBA and fee accuracy
FBA fees vary by size tier and season. Keep COGS and fee assumptions updated monthly. Profit Bid recalculates Profit on Ad Spend when costs change.
