Email Marketing ROI Calculator - Calculate Email ROI

Measure email marketing ROI from attributed revenue, direct product or service costs and campaign spend, then compare net return with revenue per dollar spent.

Email Revenue, Direct Costs and Campaign Spend

Revenue attributed to the email campaign or selected email program.
Direct costs tied to the attributed revenue, such as COGS or delivery cost.
Email platform, creative, labor, agency or other campaign cost included in this ROI scope.

Example: $20,000 Revenue From a $2,500 Email Campaign

Attributed email revenue: $20,000

Direct product/service costs: $6,000

Email campaign cost: $2,500

Gross profit: $14,000

Net return after email cost: $11,500

Email marketing ROI: 460.00%

Revenue per $1 spent: $8.00

The sample inputs shown here match the default calculator values so the example can be reproduced directly.

Formula

Gross Profit = Attributed Revenue - Direct CostsNet Return = Gross Profit - Email Campaign CostEmail Marketing ROI = Net Return / Email Campaign Cost x 100Revenue per $1 Spent = Attributed Revenue / Email Campaign Cost

Input Checklist

Attribution scope: Use revenue attributed to the same campaign or email program whose costs you enter.Direct-cost scope: Include the product or service delivery costs tied to that attributed revenue when you want a profit-based ROI.Campaign-cost scope: Apply one documented rule for platform, labor, creative, agency and other email costs when comparing periods.

Reporting Note

Attribution models and windows can assign different revenue to email. Keep the attribution method, revenue scope and cost policy consistent across comparisons. Revenue per $1 spent is an efficiency multiple; it is not the same calculation as profit-based ROI.

How to Interpret the Result
Email ROI depends on attribution and cost scope. Compare campaigns using the same attribution window, direct-cost treatment and campaign-cost policy. A high revenue-per-dollar multiple can still produce a much lower profit-based ROI when product or service delivery costs are material.

Use the costs relevant to the decision, such as platform fees, creative work, labor, agency fees and other campaign-specific expenses. Keep the scope consistent across comparisons.
No. Revenue per dollar ignores direct costs. ROI uses the net return after direct costs and email campaign cost.
