HMZ GLOBAL — SPONSORED PRODUCTS BID WORKSHEET
Guide: https://hmzglobalservices.com/amazon-placement-bid-adjustments-calculation
Planning arithmetic, not an account-specific bid recommendation.

Marketplace / campaign / product / reporting dates:
Base bid:
Placement adjustment percentage:
Bidding strategy:
Other active audience, business, schedule or bid adjustments:
Clicks / spend / attributed orders / sales:
Revenue per order / non-ad variable costs / contribution:
Desired contribution retained after ads:
Attribution completeness and conversion-rate uncertainty:

Placement-adjusted bid = base bid * (1 + placement percentage / 100)
Only with maximum 100% dynamic uplift and no other adjustments:
Potential bid = base bid * (1 + placement percentage / 100) * 2

Average CPC = spend / clicks
Ad conversion rate = attributed orders / clicks
Break-even average CPC = pre-ad contribution per order * ad conversion rate
Target average CPC = (pre-ad contribution - desired retained contribution) * ad conversion rate

Illustration: 0.60 base * 1.50 placement * 2 dynamic = 1.80 potential bid.
Illustration: 9.00 contribution * 0.10 conversion = 0.90 break-even average CPC.
Undefined denominators stay unknown. Bid ceilings are not actual charged CPC.
