How Does the Email ROI Calculator Work?
Quick Answer
The Email ROI Calculator estimates how much revenue your email marketing should generate based on your current ecommerce performance. It compares your existing email revenue against industry benchmarks to uncover missed opportunities from campaigns, automated flows, and subscriber growth.
Unlike a basic ROI calculator, this tool focuses specifically on Klaviyo email marketing performance and estimates your potential revenue gap.
What Does the Calculator Measure?
The calculator evaluates several metrics that directly influence email revenue.
| Metric | Why It Matters |
|---|---|
| Monthly Store Revenue | Establishes your baseline |
| Email Revenue % | Shows how much revenue email currently generates |
| Flow Revenue % | Measures automation performance |
| Subscriber List Size | Indicates audience potential |
| Average Order Value | Determines revenue per conversion |
| Campaign Frequency | Measures engagement opportunities |
Together, these metrics estimate how much additional revenue your email program could produce.
What Is a Good Email Marketing ROI?
Most ecommerce brands see email marketing generate one of the highest returns of any marketing channel.
While results vary by industry, healthy programs typically produce:
- Email contributes 20–40% of total ecommerce revenue
- Automated flows generate 30–50% of email revenue
- Welcome, abandoned cart, and post-purchase flows often produce the highest ROI
- Email marketing regularly outperforms paid social in long-term profitability
If your email revenue falls below these benchmarks, there may be opportunities to improve segmentation, automation, deliverability, or campaign strategy.
How Is Email ROI Calculated?
A simple ROI formula is:
Email ROI = (Revenue Generated − Cost of Email Marketing) ÷ Cost × 100
For example:
- Email revenue: $60,000
- Monthly email costs: $6,000
ROI
= ($60,000 − $6,000) ÷ $6,000 × 100
= 900% ROI
Our calculator goes beyond this formula by estimating unrealized revenue based on your current performance and industry benchmarks.
