AMAZON ADVERTISING ECONOMICS
Amazon Advertising Profit Planner
Calculate break-even ACoS, current ACoS, TACoS, and contribution after advertising from your own product economics.
Quick answer: A profitable Amazon advertising plan starts with the contribution available before ads. That number sets the break-even ACoS. Actual ACoS and TACoS then show how media affects ad-attributed sales and total account revenue.
Model one product or portfolio scenario
Use the same period for units, revenue, and ad spend. Enter per-unit costs where requested.
This planning tool uses the values you enter. It does not predict results or replace account-level finance.
Formulas used by the planner
| Metric | Formula | Decision it supports |
|---|---|---|
| Pre-ad contribution per unit | Selling price minus product cost, Amazon fees, fulfillment, and return allowance | How much contribution is available to fund advertising. |
| Break-even ACoS | Pre-ad contribution divided by selling price | The theoretical ACoS where modeled contribution reaches zero. |
| Current ACoS | Ad spend divided by ad-attributed revenue | Efficiency of sales attributed to advertising. |
| TACoS | Ad spend divided by total revenue | Media pressure across the full Amazon business. |
| Contribution after ads | Total revenue minus modeled variable costs and ad spend | Whether the scenario creates positive contribution before fixed overhead. |
Attribution windows, discounts, taxes, coupons, storage, returns, and finance conventions vary. Use account and SKU data for final decisions.
How to use the result
Diagnose the unit economics
If pre-ad contribution is weak, lowering bids alone cannot repair the offer. Review price, pack architecture, fees, fulfillment, returns, and landed cost.
Assign campaigns a role
Brand defense, category capture, conquesting, ranking support, launch, and remarketing should not share one target without context.
Connect spend to inventory
A product with limited cover, weak conversion, or a suppressed offer may need a different budget decision than a retail-ready product with reliable supply.
Compare the operating model in the Amazon advertising benchmark framework, then use the Amazon Profitability Playbook to structure the wider plan.
Amazon advertising profit planner FAQ
Is break-even ACoS the right campaign target?
Not automatically. It is a boundary from the entered unit economics. Campaign role, organic lift, customer acquisition, rank, inventory, and marginal contribution can justify different operating targets.
What is the difference between ACoS and TACoS?
ACoS compares spend with ad-attributed revenue. TACoS compares spend with total Amazon revenue. Together they help separate attributed media efficiency from the advertising load carried by the full business.
Should DSP spend be included?
Include it when revenue and attribution are measured on a comparable basis. If DSP uses a different window or objective, model it separately and reconcile the result at portfolio level.
Does the calculation include fixed overhead?
No. Contribution after ads is calculated before fixed overhead, tax, financing, and other company-specific accounting items unless you include them in the per-unit cost inputs.
How often should the model be refreshed?
Refresh it whenever price, fees, landed cost, return behavior, fulfillment, pack size, or media mix changes. High-volume products may need a weekly decision cycle.
