Campaign Scenario Calculator

About the Campaign Scenario Calculator

The Campaign Scenario Calculator is a powerful what-if analysis tool designed for digital marketers and advertisers. It allows you to model different budget scenarios and forecast how changes to your campaign parameters will impact key performance indicators (KPIs) like ROAS, CPA, conversions, and revenue.

Key Features

• Budget Scaling Analysis: See how increasing or decreasing your budget affects performance with realistic diminishing returns modeling
• Objective Change Simulation: Compare performance across different campaign objectives like Conversions, Traffic, Awareness, and more
• Best/Worst Case Projections: Understand the range of possible outcomes with adjustable uncertainty parameters
• Transparent Assumptions: All calculations are explainable with visible multipliers and elasticities
• Preset Management: Save and load your scenarios for future reference

How It Works

Enter your baseline campaign metrics (spend, CPM or CPC, CTR, CVR, AOV) and define a scenario by adjusting the budget multiplier and/or changing the objective and optimization mode. The calculator applies industry-standard elasticity curves to model how metrics scale with spend changes, then generates three projections: base case, best case, and worst case.

Use Cases

• Planning quarterly budget increases or decreases
• Evaluating the impact of switching from awareness to conversion objectives
• Preparing budget proposals with realistic performance projections
• Understanding the efficiency trade-offs of scaling campaigns
• Comparing different optimization strategies before implementation
