How to Calculate Email Marketing ROI
Email marketing consistently delivers the highest ROI of any marketing channel, averaging $36 return for every $1 spent. This calculator helps you measure the profitability of your email campaigns.
The Email Marketing ROI Formula
ROI = ((Revenue - Costs) / Costs) × 100
Also expressed as: (Net Profit / Costs) × 100
Step-by-Step Calculation
Step 1: Calculate Total Email Marketing Costs
Include all expenses related to email campaigns:
- ESP platform fees (Mailchimp, Klaviyo, SendGrid)
- Email design and development
- Copywriting and content creation
- Marketing team labor costs
- List acquisition or rental costs
- Automation and personalization tools
- A/B testing and analytics platforms
Step 2: Track Revenue from Email
Measure revenue attributed to email campaigns:
- Use UTM parameters to track in analytics
- Implement conversion tracking in ESP
- Track unique promo codes per campaign
- Use multi-touch attribution in CRM
- Count revenue within 7-30 day window post-send
Step 3: Apply the Formula
Example Calculation
- Revenue from Email: $50,000
- Email Marketing Costs: $2,000
- Net Profit: $50,000 - $2,000 = $48,000
- ROI: ($48,000 / $2,000) × 100 = 2,400%
For every $1 spent on email, you generated $24 in revenue, or $24 in profit.
