## Overview

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 result

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.

## Method

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.

## Example

- **Setup:** 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.
- **Result:** 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.
