Verdict
Your ACOS is well below your break-even point. Your campaigns are profitable.
Ad Spend ÷ Ad Revenue × 100. Should be lower than your product margin for profitable campaigns. Aim for 30–50% below break-even for a comfortable cushion.
This is the ACOS at which you make exactly zero profit on ad-driven sales. If your current ACOS is close to or above this number, your campaigns are unprofitable.
Ad Spend ÷ Total Revenue. A healthier metric than ACOS because it captures the organic sales lift from your advertising investment. Target: 5–15% for most categories.
