What this calculator does
The Email Marketing ROI Calculator models the full email funnel: list size, open rate, click-through rate, conversion rate and average order value, against your monthly email cost. The output shows expected opens, clicks, conversions, revenue, and ROI per campaign cycle. Agencies use it to forecast what a proposed email program is worth before building it, to set realistic expectations with clients, and to demonstrate the compounding value of list growth and deliverability work. Because every stage multiplies, the tool makes it obvious which lever - list, opens, clicks, or conversion - is the cheapest path to more revenue for a given account.
How to use this calculator

- 2
Enter monthly email costs (platform + production time).
- 3
Review revenue and ROI; test which stage improvement moves revenue most.
Why this matters for agencies
Email is consistently the highest-ROI owned channel, but only when its funnel math is visible. Modeling the stages shows clients why list growth and deliverability deserve budget, and which single-stage fix pays best.
Frequently asked questions
What is the average ROI of email marketing?
Industry studies consistently place email at roughly $30-$40 returned per dollar spent - the highest of any owned channel. Real ROI depends heavily on list quality and deliverability.
What costs should the calculation include?
Platform fees, template and copy production time, list management, and any agency fees for the channel. Undercounting cost overstates ROI.
Which email metric should I improve first?
Model each in this calculator - but typically deliverability and open rate first (subject lines, sender reputation, custom sending domain), because every downstream stage multiplies from opens.
Does this work for B2B lead generation emails?
Yes - replace average order value with average lead value (deal value x close rate) and conversion means a booked call or qualified lead.
