How Do You Calculate ROI With Attribution?
To calculate ROI with attribution, you quantify the value created by marketing touchpoints, validate influence across the buying journey, and compare that revenue impact against total program and channel costs to determine return.
ROI with attribution is calculated by connecting touch-level credit to pipeline and revenue outcomes, assigning value through a declared attribution model, and dividing the net revenue impact by total marketing investment. The formula is: (Attributed Revenue − Cost) ÷ Cost.
What You Need Before Calculating ROI
The ROI Calculation Workflow
A practical sequence to connect attribution outputs to financial impact.
Step-by-Step
- Define the revenue output — Choose pipeline, bookings, or ARR as the anchor metric.
- Select the attribution model — Ensure the model reflects your buying journey and lookback window.
- Collect marketing costs — Capture channel, program, tech, and labor spend for the same timeframe.
- Apply credit weighting — Use your attribution model to distribute value across touches.
- Calculate attributed revenue — Sum credited revenue across channels or programs.
- Compute ROI — Use: (Attributed Revenue − Total Cost) ÷ Total Cost.
- Reconcile with Finance — Validate revenue, cost, and timing to ensure accuracy.
Attribution Models and ROI: Key Differences
| Model | How ROI Is Calculated | Best For |
|---|---|---|
| First Touch | Credit assigned to the earliest interaction; measures early-stage influence. | Top-of-funnel visibility and new-market development. |
| Last Touch | Credit assigned to the final converting touch; measures closing impact. | Sales acceleration and conversion optimization. |
| W-Shaped | Weighted credit to first touch, lead creation, and opportunity creation. | B2B journeys with complex buying committees. |
| Data-Driven | Algorithmically distributes credit based on lift patterns. | High-volume digital programs. |
