Calculating Marketing ROI

Marketing ROI shows the return on marketing investment. It's essential for justifying budgets and optimizing spend.

Basic ROI Formula

ROI = (Revenue - Marketing Cost) / Marketing Cost × 100%

A 5:1 ratio (500% ROI) is generally considered good.

Attribution Challenges

Marketing often has delayed and indirect effects. Use attribution models to assign credit appropriately.

Channel-Specific ROI

Calculate ROI for each marketing channel to identify your most profitable investments.

Campaign ROI

Measure ROI for individual campaigns to learn what works and replicate success.

Long-Term Value

Consider customer lifetime value, not just immediate revenue, for accurate ROI calculation.

Improving Marketing ROI

  • Optimize underperforming channels
  • Reallocate budget to winners
  • Improve targeting and messaging
  • Reduce waste and inefficiency
  • Test and iterate continuously
