Email marketing ROI calculator

Plug in your list volume and typical rates to estimate the monthly revenue — and the return on investment — an email program can produce. Adjust the numbers to model best and worst cases.

That's roughly 6,048 in revenue per year.

How the estimate works

The calculator chains your funnel rates: emails sent × open rate × click rate × conversion rate gives estimated orders, multiplied by average order value for revenue. ROI compares that revenue against your monthly cost.

It's a model, not a guarantee — real results depend on your list quality, offer and timing. Use it to set expectations and see which lever (deliverability, click rate, order value) moves the number most.

Which levers matter most

  • Deliverability first — revenue is zero for mail that never reaches the inbox
  • Open rate follows subject line, sender trust and send timing
  • Click rate reflects relevance and a clear call-to-action
  • Conversion and order value depend on the offer and landing page

Frequently asked questions

What rates should I enter?

Use your own historical averages if you have them. If not, the pre-filled figures are reasonable starting points for an engaged list — then adjust to your reality.

Why is email ROI usually so high?

Because sending cost is low relative to the revenue an engaged, permissioned list produces. The gap is why email consistently ranks among the highest-ROI channels.
