Formula

Clicks

clicks = emailsDelivered × clickThroughRate

Attributed conversions

attributedConversions = clicks × clickToConversionRate × attributionRate

Net revenue per conversion

netRevenuePerConversion = (averageOrderValue + repeatPurchaseValue) × (1 - refundRate)

Email ROI

roi = (grossProfit - totalCost) / totalCost

Break-even conversion rate

breakEvenConversionRate = totalCost / (clicks × attributionRate × netRevenuePerConversion × grossMarginRate)

Assumptions

Click-through, click-to-conversion, unsubscribe, refund, attribution, and gross margin percentages are entered as human-readable percentages and converted to decimals internally.
Attributed conversions are gross conversions multiplied by the entered attribution rate.
Total cost includes campaign cost, list acquisition cost, software cost, and creative cost.
Outputs are deterministic scenario math, not campaign forecasts or guarantees.

Worked example

Example: campaign ROI

With 50,000 delivered emails, a 3% click-through rate, 4% click-to-conversion rate, 80% attribution, $200 net revenue per conversion before refunds, 65% gross margin, and $3,500 total cost, attributed revenue is $9,408 and ROI is about 75%.

FAQ

Is this an email revenue forecast?

No. It is a deterministic scenario model based only on the assumptions entered in the form.

Why use an attribution rate?

Attribution rate lets you credit only a portion of modeled conversions to email when other channels or touchpoints may have contributed.

How is break-even conversion rate calculated?

The calculator solves for the click-to-conversion rate required for gross profit to equal total campaign cost under the entered click volume, attribution, net revenue, and margin assumptions.
