Calculate email campaign ROI with list size, open rate, CTR, conversion rate, average order value, and campaign costs.
The Email Marketing ROI Calculator turns a mailing list and campaign performance assumptions into estimated opens, clicks, conversions, revenue, profit, and return on investment. It applies the open, click-through, and conversion rates in sequence, then multiplies conversions by average order value and compares the resulting revenue with campaign cost. A frequent mistake is entering a conventional delivered-email CTR. Here, CTR follows opens in the funnel, so it represents the share of estimated opens that click.
A concrete input and expected output from the current implementation.
Input
List size: 2; open rate: 100%; CTR: 100%; conversion rate: 100%; average order value: $10; campaign cost: $5
Expected output
Estimated opens: 2; estimated clicks: 2; estimated conversions: 2; estimated revenue: $20; net profit: $15; ROI: 300%
All two recipients pass through every funnel stage. Two conversions at $10 produce $20 revenue; subtracting $5 leaves $15, and $15 / $5 x 100 equals 300%.
List size is multiplied by open rate to estimate opens. Those opens are multiplied by CTR to estimate clicks, and clicks are multiplied by conversion rate to estimate conversions. Average order value then converts the expected conversions into revenue. Fractional conversions can appear because the calculation represents an expected outcome rather than a count of completed orders.
Net profit is estimated revenue minus campaign cost. ROI is that net profit divided by campaign cost, multiplied by 100. A 0% result means estimated revenue exactly covers the entered campaign cost. A negative result indicates a modeled loss. ROI is not meaningful when campaign cost is zero because the calculation would require division by zero.
Open rate estimates how many listed recipients open the message, while CTR estimates how many of those opens lead to clicks. For this funnel, enter an open-based click rate, often called click-to-open rate. No, a CTR calculated from all delivered messages is not interchangeable without converting it to the required denominator.
No, not as separate inputs. Average order value converts estimated orders into revenue, while campaign cost supplies the expense used in ROI. If product costs, refunds, payment fees, discounts, or fulfillment costs matter, account for them separately or incorporate an appropriate amount into costs. Otherwise, treat the result as campaign ROI rather than complete business profitability.
