Email Marketing ROI Calculator

What this does

An email marketing ROI calculator models a campaign from sends through opens, clicks, and conversions to revenue, then ROI against the campaign cost.

How to use it

1. Enter the number of sends.
2. Enter open, click, and conversion rates.
3. Enter average order value and cost.
4. Read the revenue and ROI.

How it works

Each stage applies a rate to the one before it, so the click rate here is the share of openers who click (click-to-open rate). If your platform reports clicks as a share of sends, divide that by the open rate first.

revenue = sends × open% × click% × conv% × AOV

Understanding your result

The result traces how a send list narrows through opens, clicks, and conversions into revenue, then weighs that against cost. Because each stage multiplies the one before it, a small lift early in the funnel compounds, so find the weakest stage to see where extra effort returns the most.

Example

10,000 sends at a 20% open rate, 10% click-to-open and 5% conversion is 2,000 opens, 200 clicks and 10 orders; at $80 each that is $800 of revenue, a 60% ROI on a $500 campaign.
