Planning
Ad Spend Scenario Planning for Ecommerce
Scenario planning helps sellers avoid scaling based on one optimistic ad result. Build at least three cases before committing more budget: conservative, expected and aggressive.
Conservative case
Use higher ad cost, higher return rate and lower conversion assumptions. If the product still has positive contribution profit, it may be resilient.
Expected case
Use realistic numbers from early tests or comparable products. This should be the base case for inventory and budget planning.
Aggressive case
Use improved conversion and stronger ad efficiency. This case is useful for upside planning, but should not be the only reason to launch.
How to use scenarios
Save each calculator result, compare profit per order and monthly profit, then identify which cost input has the biggest effect. Improve that input before scaling.
