Marketing Calculators
Email Marketing ROI Calculator
Estimate what your newsletter or email campaigns earn each month.
Runs entirely in your browser — nothing you enter is sent or stored.
How it works
Emails sent = subscribers × sends. Clicks = sent × click rate. Orders = clicks × conversion rate. Revenue = orders × order value. ROI = (revenue − cost) ÷ cost. Open rates are shown for context only — Apple Mail Privacy Protection inflates them, so clicks are the reliable number.
Frequently asked questions
Why not calculate from opens?
Since 2021 many email apps pre-load images, which records an "open" whether or not a person read the email.
How often should I email?
As often as you have something useful to say. Weekly is a sustainable rhythm for most small businesses.
