Email Marketing ROI Calculator

Calculate return on investment for an email campaign from emails sent, campaign cost, conversions, and average order value.

Email marketing ROI is (revenue generated minus campaign cost) divided by campaign cost, times 100. Revenue is conversions multiplied by average order value. A campaign that costs $800, sends 50,000 emails, and drives 350 conversions at a $65 average order value generates $22,750 in revenue and roughly a 2,744% ROI.

Formula

Email marketing ROI formula

Revenue = Conversions × Avg. Order Value. ROI = (Revenue − Campaign Cost) ÷ Campaign Cost × 100.

Campaign cost should include everything spent to produce and send the campaign: platform/ESP fees, design and copywriting time, and any list rental or paid promotion.

Step by step

How the calculation works

1Enter total emails sent for the campaign.
2Enter total campaign cost — platform fees, design, copywriting, and any paid promotion.
3Enter the number of conversions (purchases, signups, or whatever counts as a conversion for this campaign).
4Enter the average order value (or average value per conversion) to calculate revenue and ROI.

Example

Email marketing ROI example

A campaign sent to 50,000 subscribers costing $800, driving 350 conversions at a $65 average order value, generates $22,750 in revenue, $21,950 in net profit, and roughly 2,744% ROI.

Quick Answer: How Email Marketing ROI Is Calculated

Email marketing ROI is (revenue generated minus campaign cost) divided by campaign cost, expressed as a percentage. Revenue is conversions multiplied by average order value. A campaign that costs $800 to send to 50,000 subscribers and drives 350 conversions at a $65 average order value generates $22,750 in revenue, $21,950 in net profit, and roughly 2,744% ROI.

Email consistently posts some of the highest ROI of any marketing channel because the marginal cost of sending one more email is close to zero — the campaign cost is largely fixed (platform fee, design time, copywriting), so revenue scales with list size and conversion rate while cost barely moves.

How to Use This Calculator

Enter total emails sent, total campaign cost (platform/ESP fees, design and copywriting time, any list rental or paid promotion used to grow the list), the number of conversions the campaign drove, and the average order value per conversion.

The calculator multiplies conversions by average order value to get revenue, subtracts campaign cost to get net profit, and divides net profit by campaign cost to get ROI. It also reports conversion rate (conversions ÷ emails sent) and cost per conversion (campaign cost ÷ conversions) so you can compare this campaign against others even when list sizes differ.

The Formula This Calculator Uses

$$\text{Revenue} = \text{Conversions} × \text{Average Order Value}$$

$$\text{Net Profit} = \text{Revenue} - \text{Campaign Cost}$$

$$\text{ROI} = \dfrac{\text{Net Profit}}{\text{Campaign Cost}} × 100$$

$$\text{Conversion Rate} = \dfrac{\text{Conversions}}{\text{Emails Sent}} × 100$$

$$\text{Cost Per Conversion} = \dfrac{\text{Campaign Cost}}{\text{Conversions}}$$

Worked Example: A Mid-Size List

50,000 emails sent, $800 campaign cost, 350 conversions, $65 average order value.

Revenue: 350 × $65 = $22,750.

Net profit: $22,750 − $800 = $21,950.

ROI: $21,950 ÷ $800 × 100 = 2,743.75%.

Conversion rate: 350 ÷ 50,000 × 100 = 0.7%.

Cost per conversion: $800 ÷ 350 ≈ $2.29 — extremely low compared to most paid acquisition channels, which is the core economic advantage of an owned email list.

Second Worked Example: A Small List

2,500 emails sent, $150 campaign cost, 20 conversions, $45 average order value.

Revenue: 20 × $45 = $900.

Net profit: $900 − $150 = $750.

ROI: $750 ÷ $150 × 100 = 500%.

Conversion rate: 20 ÷ 2,500 × 100 = 0.8%.

Cost per conversion: $150 ÷ 20 = $7.50. ROI is still strongly positive even at a small list size and a lower absolute order value — email's low fixed cost means it stays efficient at scale in both directions.

Why Email ROI Looks So High Compared to Paid Channels

Paid acquisition channels (search ads, social ads) charge per impression or per click regardless of whether that traffic converts, so cost scales directly with volume. Email marketing cost is largely fixed once you've built the list — the ESP platform fee and the time to write and design a campaign don't change much whether you send to 5,000 subscribers or 500,000. That's why the ROI percentages above look dramatically higher than typical paid-channel benchmarks: the denominator (campaign cost) stays small while revenue scales with list size and engagement.

This doesn't mean email replaces paid acquisition — list building itself has real costs (lead magnets, paid list growth, content creation) that this calculator doesn't capture. It's a channel-efficiency comparison, not a complete picture of total marketing cost.

What Counts as Campaign Cost

Include every real cost tied to producing and sending the campaign: your email service provider (ESP) fee for that send (or an allocated share of a monthly subscription), design and copywriting time (valued at a reasonable hourly rate if done in-house), any stock imagery or paid creative assets, and any spend used specifically to grow the list this campaign was sent to. Leaving out labor cost is the most common way email ROI gets overstated — a campaign that took eight hours of a marketer's time to write and design isn't actually free just because the ESP fee is small.

What This Number Doesn't Capture

This calculator measures a single campaign's direct, attributed conversions — it doesn't account for multi-touch attribution (a customer who saw this email but converted after also seeing a retargeting ad), brand-awareness value that doesn't show up as an immediate conversion, unsubscribe or spam-complaint cost to long-term list health, or the cost of building the list in the first place. Treat a single high ROI figure as one data point, and compare it against your own campaign history rather than external benchmarks, since list quality and audience intent vary enormously between businesses.

Related Calculators

If open rates are lagging and conversions are suffering as a result, diagnose the funnel with the email open rate calculator. For a blended view across every channel, compare against the marketing ROI calculator, and if you also run SMS campaigns, the SMS marketing conversion calculator uses the same conversion-rate logic for that channel.

Attribution

The method used to credit a conversion to a specific marketing touchpoint — single-touch (like this calculator assumes) or multi-touch across several channels.

Frequently Asked Questions

What's a good ROI for an email marketing campaign?+

There's no universal benchmark, since it depends heavily on list quality, industry, and average order value, but email consistently ranks among the highest-ROI marketing channels because the marginal cost per send is very low. Compare a campaign against your own historical campaigns rather than an external number.

What should I include in campaign cost?+

Your ESP or platform fee, design and copywriting time (even if done in-house), any paid creative assets, and any spend used to grow the specific list the campaign was sent to. Leaving out labor time is the most common way ROI gets overstated.

Why is my conversion rate so much lower than my open rate?+

Open rate measures who opened the email; conversion rate measures who completed the target action (a purchase, signup, etc.). A large gap between the two usually points to a weak call-to-action, an unclear offer, or friction on the landing page the email links to.

Should I use total revenue or incremental revenue for this calculation?+

Ideally, use revenue you can reasonably attribute to this specific campaign — a discount code, a UTM-tagged link, or a dedicated landing page. Using total store revenue for the period would overstate the campaign's actual impact.

Does list size alone predict ROI?+

No. A smaller, highly engaged list often outperforms a larger, disengaged one on both conversion rate and ROI, since campaign cost stays roughly fixed regardless of list size while irrelevant sends can hurt deliverability and long-term engagement.

How is this different from marketing ROI in general?+

This calculator is scoped to a single email campaign's direct cost and conversions. A blended marketing ROI figure would combine multiple channels and total marketing spend — use the marketing ROI calculator for that broader view.

What if my campaign had zero conversions?+

ROI would be −100% (you spent the campaign cost and generated no attributable revenue). This is a useful signal to review subject lines, segmentation, offer relevance, or deliverability before the next send.

How the calculation works

1Enter total emails sent for the campaign.

2Enter total campaign cost — platform fees, design, copywriting, and any paid promotion.

3Enter the number of conversions (purchases, signups, or whatever counts as a conversion for this campaign).

4Enter the average order value (or average value per conversion) to calculate revenue and ROI.
