About this calculator
This calculator turns your email campaign numbers into a clear picture of revenue and return on investment. Enter your list size, deliverability, open rate, click-to-open rate, conversion rate, average order value, and campaign cost — and you get revenue, ROI %, revenue per send, cost per conversion, and a five-stage funnel showing exactly where subscribers drop off.
How to read your results
The headline figures are ROI % and total revenue. A positive ROI means the campaign earned more than it cost; a negative ROI means the campaign ran at a loss. The funnel breakdown (sent → delivered → opened → clicked → converted) pinpoints which stage loses the most subscribers, so you know where to focus optimization. Revenue per send is a useful cross-campaign benchmark: higher is better regardless of list size.
How it's calculated
The calculator applies a sequential funnel: delivered = sends × (deliverability / 100); opened = delivered × (open rate / 100); clicked = opened × (click-to-open rate / 100); converted = clicked × (conversion rate / 100); revenue = converted × average order value. ROI is then (revenue − campaign cost) / campaign cost × 100, returning 0 when campaign cost is zero. Revenue per send = revenue / sends (0 when sends is zero). Cost per conversion = campaign cost / converted (0 when converted is zero). The formula is consistent with the ROI model described by Omnisend and the funnel benchmarks published by Mailchimp.
Worked example
Send 10,000 emails with 98% deliverability, 25% open rate, 10% click-to-open rate, 5% conversion rate, average order value of 50, and a campaign cost of 200.
The funnel delivers 9,800 emails, 2,450 opens, 245 clicks, and 12.25 conversions. Revenue is 612.50, giving an ROI of 206.25% and a revenue per send of 0.0613. Cost per conversion is 16.33.
Frequently asked questions
What does click-to-open rate (CTOR) mean?
CTOR is the percentage of people who opened your email and then clicked a link inside it. It isolates the quality of your email content and call-to-action from list-quality effects. A higher CTOR means the content inside the email is compelling; a lower one suggests the body copy or offer needs work regardless of how many people opened it.
Why is my ROI shown as 0% when I have revenue?
ROI is calculated as (revenue − campaign cost) / campaign cost × 100. If you enter a campaign cost of 0, the calculator returns 0% to avoid a division-by-zero result. Enter the actual cost — including tool subscriptions, copywriting, and design time — to get a meaningful ROI figure.
What is a realistic open rate or CTOR benchmark?
Industry benchmarks vary widely by sector. Mailchimp data puts average open rates between 20–35% for most industries, with CTORs around 10–15%. Omnisend reports broadly similar ranges. These are averages — a highly targeted, permission-based list can exceed them significantly, while a cold or stale list will fall well below.
How do I improve my cost per conversion?
Cost per conversion falls when either the campaign costs less or more recipients convert. Practical levers include segmenting your list to improve relevance, A/B testing subject lines to lift open rates, optimizing your call-to-action to raise CTOR, and improving the landing page to convert more clicks. Each improvement compounds through the funnel.
Does this calculator account for unsubscribes or spam complaints?
No. The model focuses on the revenue and cost side of a single send. Unsubscribes and complaints affect long-term list health and deliverability — factors that influence future campaigns — but are not part of the single-campaign ROI formula used here.
