Model Your Growth Now

How It Works – Step by Step

• Set Baseline Metrics: Enter initial users, spend, CAC, churn, ARPU, and virality.
• Adjust Variables: Change any one metric and instantly see projected outcomes.
• Review Outputs: The model calculates 6-month revenue and user growth.
• Get AI Insight: The app highlights your highest-leverage change with actionable recommendations.
• Refine Strategy: Use the insights to adjust acquisition tactics, retention plays, or pricing models.

Understanding Your Results

The outputs include:

• 6-Month Revenue: Total projected revenue based on your chosen inputs.
• Users After 6 Months: Growth in active users driven by churn, virality, and acquisition.
• High-Leverage Change: The single adjustment that most improves growth efficiency.
• AI Insight: Contextual explanation of why that lever matters and how to act on it.

How to Use Your Analysis:

• Check Unit Economics: Ensure CAC is sustainable relative to ARPU.
• Prioritize Retention: Lower churn to Stabilize Long-Term Growth.
• Test Pricing Power: Model a higher ARPU to see the impact on faster CAC recovery.
• Balance Acquisition vs. Virality: Adjust the K-Factor to Test Compounding Growth Effects.
• Plan Scenarios: Develop multiple ‘what-if’ models before making significant investments or implementing pricing changes.

When to Use This App

• During fundraising, if you need to validate assumptions in your growth story.
• When planning pricing or packaging changes.
• Before scaling acquisition spend across channels.
• For quarterly reviews of churn, ARPU, and CAC efficiency.
• To evaluate the ROI of retention vs. acquisition initiatives.

Growth Modeling Benchmarks 2025

Benchmarks provide a reference for evaluating your modeled outcomes against typical growth businesses.

Note: These benchmarks are directional averages. Actual performance varies by industry, stage, and market conditions.

Practical Examples

Example 1 – Baseline Scenario
Inputs: CAC $50, ARPU $20, Churn 5%
Outputs: $210k revenue, 3,049 users after 6 months
Interpretation: CAC recovery is too slow, resulting in a loss of money on each new customer.

Example 2 – Pricing Optimization
Inputs: Increase ARPU from $20 to $30
Outputs: Higher 6-month revenue with faster CAC recovery
Interpretation: Pricing is the highest-leverage lever to create sustainability.

Example 3 – Churn Reduction
Inputs: Reduce churn from 5% to 3%
Outputs: Significant uplift in retained users, compounding growth
Interpretation: Retention stabilizes growth and reduces acquisition pressure.

Growth Tips & Business Impact

• Focus on ARPU vs. CAC: Always ensure ARPU covers CAC within a reasonable timeframe.
• Retention Before Scale: Lower Churn Before Increasing Acquisition Spend.
• Leverage Virality: Improving K-Factor, even slightly, creates outsized gains.
• Model Multiple Paths: Compare aggressive vs. conservative assumptions to stress-test growth.
• Share in Investor Decks: Use the outputs to communicate growth levers transparently.

Business Impact: Teams using the What-If Growth Modeler avoid costly scaling mistakes, validate pricing and retention moves, and build a clear roadmap for compounding growth.
