Estimate email conversion rate and cost per conversion from delivered traffic, actions, and spend.
Use this email conversion rate calculator to evaluate how efficiently email traffic becomes the action you care about. The calculator is designed to give a fast answer, but the quality of the answer still depends on accurate inputs and a clear idea of what decision you are trying to support.
- Enter Email clicks or visits, Email conversions, and Email campaign spend using the same units you plan to compare or report.
- Read the main conversion rate first, then use the supporting outputs to understand the trade-offs behind that result.
- Compare your numbers with the worked examples below if you want a quick reasonableness check.
Conversion rate shows how much of your traffic completes the target action, while cost per conversion links campaign performance directly to spend. On this page, the primary output is conversion rate.
Scenario 1: 4,800 email visits, 312 conversions, $640 spend. Inputs used: visitors: 4800, conversions: 312, adSpend: 640. Example result: 6.50%. This email campaign setup produces a conversion rate of 6.50%. Scenario 2: 12,500 email visits, 510 conversions, $1,800 spend. Inputs used: visitors: 12500, conversions: 510, adSpend: 1800. Example result: 4.08%. For this larger email program, the conversion rate works out to 4.08%.
Core formula: conversion rate = conversions / visitors * 100. The calculator compares completed actions with total traffic to show how efficiently a page, campaign, or funnel turns visitors into results.
- Cost per conversion uses ad spend divided by conversions.
- Consistent attribution windows matter if you compare campaigns across time periods.
Use this calculator when reviewing landing pages, campaigns, funnels, or channel performance and you need a fast conversion benchmark.

Most bad outputs come from a few repeated input errors or interpretation mistakes. Use this short checklist before relying on the result.
- Comparing campaigns that use different conversion definitions.
- Using mismatched time windows for traffic, conversions, and spend.
- Looking only at conversion rate without checking conversion quality or revenue.
