Ad Budget Planner

Setting the right ad budget is one of the most important decisions for any eCommerce brand. Spend too little and you never get enough data to optimize. Spend too much without a plan and you burn cash.

Start with your target monthly revenue. This is the number you want your ad campaigns to generate. Then set your expected ROAS based on historical performance or industry benchmarks. The calculator divides revenue by ROAS to give you the required ad spend.

Adding your average order value unlocks estimated order volume and CPA. These metrics help you validate whether the budget makes sense: if the CPA is higher than your profit per order, you need a higher ROAS target or better margins.

The projection table shows cumulative spend and revenue at 3, 6, and 12 months, giving you a roadmap for planning cash flow and inventory around your growth targets.
