    How It Works

    Two ways to calculate an Amazon PPC budget

    Method 1

    ROAS-Based Budget

    Required Ad Sales ÷ Expected ROAS

    This determines how much you can spend while maintaining the selected ROAS.

    Method 2

    Traffic-Based Spend

    Required Clicks × Average CPC

    This estimates what the required traffic will cost based on CPC and conversion rate.

    Feasibility Test

    Maximum CPC

    ROAS Budget ÷ Required Clicks

    This shows the average CPC your conversion rate can support at the selected ROAS.

    Feasibility Test

    Required Conversion Rate

    Required Orders ÷ Affordable Clicks

    This shows the conversion rate required at the entered CPC and ROAS-based budget.

    Planning Realistically

    Why revenue goals and PPC budgets often disagree

    A revenue target may appear achievable based on ROAS alone, but CPC, conversion rate, and average order value determine whether the required traffic can actually be purchased within that budget.

    If traffic-based spend exceeds the ROAS-based budget, at least one assumption must change. You may need a lower CPC, higher conversion rate, higher order value, larger budget, lower revenue goal, or lower ROAS target.

    Analyze your current ROAS, ACoS and TACoS

    Before finalizing your budget

    01

    Use a realistic, recent advertising conversion rate.

    02

    Use a blended CPC that reflects the campaigns you plan to run.

    03

    Separate aggressive growth goals from profitability targets.

    04

    Allow for seasonality, promotions, and changes in competition.

    Frequently Asked Questions

    Amazon PPC budget FAQs

    How do I calculate an Amazon PPC budget?

    Divide the ad-attributed sales you need by your expected ROAS. For example, generating $40,000 in advertising sales at a 4.00x ROAS requires approximately $10,000 in ad spend.

    How do I calculate a daily Amazon advertising budget?

    Divide your planned monthly advertising spend by the number of selling days. Account-level daily budgets may need to be higher to accommodate uneven demand and campaign-level budget allocation.

    Why does traffic-based spend differ from my ROAS budget?

    Your entered CPC and conversion rate may imply a different ROAS than the ROAS target selected. The calculator displays the maximum CPC and required conversion rate needed to reconcile those assumptions.

    Does this calculator forecast actual Amazon sales?

    No. It translates your assumptions into budget and traffic requirements. Actual sales can differ because of demand, competition, inventory, pricing, conversion changes, and advertising attribution.
