Email Marketing ROI Calculator
Estimate email campaign ROI using your campaign data. Build and plan your next email campaign.
How this Email Marketing ROI Calculator Works?
What this tool does: it estimates the money you will make (or lose) from one email campaign after all the main costs. You enter a few simple numbers; we crunch the funnel, revenue, costs, and ROI.
Pick your input style:
- Funnel Mode: You know your typical open rate, click-through rate (CTR), and conversion rate from clicks, plus your average order value (AOV). We simulate the journey: Delivered → Opens → Clicks → Conversions.
- Known Conversions Mode: You already have a conversion forecast. Enter either a conversion count or a conversion % of delivered (and your AOV).
- Known RPE Mode: Fastest option. If you track Revenue per Email (RPE), type that in and we will multiply by the number of emails sent.
Costs first (what we add up): Delivered emails are Emails × Deliverability. Sending cost uses your ESP model (per-email, a flat campaign fee, or a monthly fee with a % allocation for this campaign). Then we add creative/design, list/lead, other, and labor (hours × rate). That total becomes your Total Campaign Cost.
Revenue & contribution (what you earn): Revenue depends on the mode you chose:
• Funnel/Known conversions: Conversions × AOV (plus any extra per-conversion revenue if you added it).
• Known RPE: Emails × RPE.
We then estimate contribution (the part of revenue available to cover costs and profit). You can:
- Apply a Gross margin % to revenue (common in ecommerce/CPG), or
- Subtract a variable cost per conversion (useful if each conversion has a known cost), or
- Mark revenue as already net of COGS (we treat revenue as contribution).
Profit & ROI (the bottom line): Net Profit = Contribution − Total Cost. Then ROI % = (Net Profit ÷ Total Cost) × 100. We also show handy rates-RPE, EPC (earnings per click), and CPA (cost per acquisition)-plus a quick break-even view (e.g., required RPE or conversions).
A quick example:
When you plan to send 5,000 emails with 98% deliverability (so ~4,900 delivered). You pick the Funnel mode with CTR 2.5% and conversion rate 1.5% of clicks. That gives ~123 clicks and ~2 conversions (rounded). If your AOV is $2,000, revenue is about $4,000. With a 60% margin, contribution is $2,400.
Let’s say sending cost is per-email at $0.80 ($4,000), plus creative $5,000, and a little labor $4,000 (5 hrs × $800). Total campaign cost ≈ $13,000. Net Profit ≈ $2,400 − $13,000 = −$10,600 → a negative ROI. That is your cue to adjust: increase volume, improve CTR/CVR, raise AOV, trim costs, or switch to Known RPE if you already track a stronger revenue/email.
Tips:
- Deliverability: 95–99% is typical; if it is lower, check list quality and sender reputation.
- Where rates apply: CTR is on delivered; Funnel conversion rate is on clicks; Known-conversions rate is on delivered.
- Sensitivity: use the Conservative/Optimistic toggle (±10% to conversion) to see best/worst case quickly.
- Break-even shortcuts: In RPE mode, compare your RPE to the tool’s break-even RPE (Total Cost ÷ Emails). Above it? You’re profitable.
