Frequently Asked Questions — Amazon Max CPC & Target Bidding
Clear answers on how to set profitable bids based on conversion rate and selling price
What is Max CPC (Target Bid) on Amazon?▼
Max CPC (Cost Per Click) is the maximum bid amount you can afford to pay for a click on Amazon PPC ads while maintaining your target ACoS (Advertising Cost of Sale) and profit goals.
How is Max CPC calculated?▼
Max CPC formula: Selling Price × (Target ACoS % ÷ 100) × (Conversion Rate CVR % ÷ 100). For example, a $50 product with a 25% target ACoS and a 10% CVR has a Max CPC of $50 × 0.25 × 0.10 = $1.25.
Why should I use actual CVR from Seller Central?▼
Using actual conversion rates from Seller Central (found in Business Reports or Campaign Manager) ensures your max bids are realistic. Estimating CVR can lead to overbidding and lost profitability.
What is Effective ACoS at Current CPC?▼
Effective ACoS calculates what your ACoS will actually be if you pay your current CPC, given your current selling price and unit conversion rate: Effective ACoS = (Current CPC ÷ (Price × CVR %)) × 100.
How do I use the recommended bid adjustment %?▼
The recommended bid adjustment percentage shows how much you should increase or decrease your current CPC to align with your target max bid. Recommended Bid Adjustment = ((Max CPC - Current CPC) ÷ Current CPC) × 100.
