    Email Marketing ROI Calculator

    Email remains the highest-ROI channel in marketing — averaging roughly $36 back per $1 — but your list's economics are what matter. This calculator walks the full funnel: sends × click rate × conversion rate × order value, against campaign cost, to project revenue and ROI per send.

    Email averages ~$36 back per $1 spent across industries

    Use it to value list growth too: once you know revenue per send, each subscriber has a concrete monthly value — which tells you what you can afford to pay for acquisition.

    How to Use the Email Marketing ROI Calculator

    1. 1Enter sends, click rate, and click-to-purchase conversion.
    2. 2Add average order value and campaign cost.
    3. 3Read projected clicks, orders, revenue, and ROI.
    4. 4Divide revenue by list size to get per-subscriber value.

    Frequently Asked Questions

    What are average email marketing benchmarks?
    Across industries: open rates 25–40% (post-Apple-MPP inflated), click rates 1–3% of delivered, click-to-purchase 2–5% for e-commerce. Beat your own history, not the averages.
    Is email really 36:1 ROI?
    That's the widely cited cross-industry average (DMA/Litmus studies) — driven by email's near-zero marginal send cost. Your number depends on list quality and offer fit; this calculator gives yours.
    How much is one subscriber worth?
    Monthly email revenue ÷ list size. If 10,000 subscribers drive $4,000/month, each is worth $0.40/month (~$4.80/year) — your ceiling for acquisition cost per subscriber.
