Email Marketing ROI Calculator

Email marketing ROI is the return you generate from email relative to what you spend on it, expressed as a percentage. It's calculated as ((Revenue - Cost) / Cost) × 100, using the revenue you attribute to email and the cost of running your email marketing for the same period.

Subtract your email marketing cost from the revenue it generated, divide that by the cost, then multiply by 100. For example, $2,000 revenue and $500 cost gives ((2000-500)/500) × 100 = 300% ROI. Just make sure the cost and revenue cover the same time period or campaign.

ROI = ((Revenue - Cost) / Cost) × 100. Related figures worth tracking alongside it are Net Return (Revenue - Cost) and Revenue Multiple (Revenue / Cost), which show the same relationship in different, sometimes more intuitive, forms.

It should, if you want an accurate number. Your email marketing cost should include your email platform subscription and any design, copywriting, or agency/freelancer fees tied specifically to email — not just ad spend or none of your costs at all.

No. This calculator measures return based on revenue attributed to email, not true business profit. It doesn't account for product costs, fulfillment, refunds, payment processing, staff costs, or other operating expenses unless you've included them in your email marketing cost input.

There's no single universal benchmark. What counts as good depends on your business model, gross margins, customer lifetime value, acquisition costs, attribution method, and campaign objectives. A 300% ROI might be strong for one business and unremarkable for another with higher margins.

It's only as accurate as the numbers and attribution method you put in. This tool does the arithmetic correctly and flags edge cases like zero cost, but it can't verify whether your revenue figure genuinely came from email rather than other marketing running at the same time.
