How to Use This Tool

Follow these steps to generate accurate marketing attribution revenue reports:

  1. Enter your total campaign revenue and select the appropriate currency for your region.
  2. Choose the attribution model that matches your current marketing measurement strategy.
  3. Input total conversions generated across all marketing channels during the campaign period.
  4. Fill in details for up to 3 core marketing channels: include the channel name, total spend, and attributed conversions for each.
  5. Click the Calculate Attribution button to view your breakdown, or Reset Form to clear all inputs.

Formula and Logic

This calculator uses standard marketing attribution formulas adjusted for your selected model:

  • Revenue per Conversion = Total Campaign Revenue / Total Campaign Conversions
  • Base Attributed Revenue (First/Last Touch) = Channel Attributed Conversions × Revenue per Conversion
  • Linear Model Attributed Revenue = (Channel Conversions / Total Touchpoints) × Revenue per Conversion (assumes 3 touchpoints per conversion, one per tracked channel)
  • Time-Decay Model allocates 50% of revenue to the most recent channel, 30% to the middle channel, 20% to the earliest channel
  • Position-Based Model allocates 40% to first touch, 40% to last touch, 20% to middle touchpoints
  • ROAS (Return on Ad Spend) = Attributed Channel Revenue / Channel Spend
  • ROI (Return on Investment) = ((Attributed Channel Revenue - Channel Spend) / Channel Spend) × 100

All calculations assume conversions are evenly distributed across touchpoints for multi-touch models unless specified otherwise.

Practical Notes

For accurate results, align inputs with standard e-commerce and marketing benchmarks:

  • Most small e-commerce businesses aim for a minimum ROAS of 3x to maintain healthy profit margins after deducting product costs and overhead.
  • Last-touch attribution is the most common model for direct-to-consumer brands, while linear models are preferred for long sales cycle B2B businesses.
  • Attributed conversions should reflect unique customer interactions: avoid double-counting customers who interact with multiple channels.
  • Channel spend must include all associated costs: ad creative, management fees, and platform commissions, not just media spend.
  • Industry average marketing ROI ranges from 10% to 30% for retail, and 20% to 50% for software-as-a-service (SaaS) businesses.

Why This Tool Is Useful

Marketing teams and business owners often struggle to allocate budget effectively without clear attribution data:

  • Identify underperforming channels that drain budget without generating proportional revenue.
  • Justify marketing spend to stakeholders with clear ROI and ROAS breakdowns per channel.
  • Adjust attribution models to test how different measurement approaches impact budget allocation decisions.
  • Compare performance across 3 core channels in one view, eliminating the need for manual spreadsheet calculations.
  • Copy results directly to reports or presentations with the one-click copy function.

Frequently Asked Questions

What attribution model should I use for a new e-commerce store?

New stores with short sales cycles (1-3 days) should start with last-touch attribution, as most customers convert quickly after their final interaction. Switch to linear or position-based models once you have 6+ months of customer journey data.

How do I calculate attributed conversions for a channel?

Use your analytics platform (Google Analytics, Meta Ads Manager) to pull conversion data assigned to each channel under your chosen attribution model. For last-touch, this is the number of conversions where the channel was the final interaction before purchase.

What is a good ROAS for social media marketing?

Average ROAS for social media channels ranges from 2x to 5x depending on industry: fashion and lifestyle brands average 3.5x, while high-margin electronics brands often see 4.5x+. Aim for at least 3x to cover product costs and overhead.

Additional Guidance

To get the most value from this tool, follow these best practices:

  • Run calculations monthly to track changes in channel performance over time, rather than relying on one-off snapshots.
  • Cross-reference results with your platform-native analytics to catch discrepancies in conversion tracking.
  • Exclude branded search campaigns from attribution calculations if you want to measure new customer acquisition performance.
  • Adjust channel inputs quarterly as you scale spend: high-growth channels may see decreasing ROAS as you reach saturation.
