What is an Email Marketing ROI Calculator?
Email marketing consistently delivers the highest ROI of any digital channel — often ₹35–42 return for every ₹1 spent globally. But most Indian small businesses track vanity metrics like open rates and ignore what actually matters: revenue generated per campaign and cost per conversion.
This free email marketing ROI calculator walks you through the funnel: list size → open rate → click rate → conversion rate → average order value. It outputs campaign revenue, total cost, ROI percentage, and cost per conversion — the four numbers your email program actually needs.
Use it to benchmark campaigns, justify email software costs to stakeholders, or set targets for your next newsletter. For Indian SaaS companies, typical benchmarks are 22–28% open rate, 2.5–4% CTR, and 1–3% conversion rate.

Using the Email Marketing ROI Calculator in 4 steps
No onboarding, no signup. Answer three fields and the numbers update live.
Enter list size and open rate
Your subscriber count and the percentage who open your emails (check your ESP dashboard for actuals).
Set CTR and conversion rate
CTR = clickers / openers. Conversion rate = buyers / clickers. Both available in your ESP and Google Analytics.
Enter average order value and campaign cost
AOV from your store backend. Campaign cost = ESP cost + copywriting + design time.
Review ROI and cost per conversion
Compare against your channel benchmarks. A positive ROI above 1000% is excellent for email.
Tips to get the most out of it
Segment your list — even a simple active/inactive split improves open rates by 20–30%.
A/B test subject lines on 20% of the list before sending to the rest.
Scrub inactive subscribers every 90 days to maintain deliverability and reduce ESP costs.
Calculate ROI per campaign type — promotional vs. nurture vs. transactional — they vary dramatically.
Include email cost as the fully-loaded cost: ESP fees, copywriter time, designer time, and your own time.
Real-world scenarios
How Indians actually use this calculator — concrete inputs, concrete outcomes.
Flash sale campaign
List: 10,000. Open rate: 25% (2,500). CTR: 8% (200). Conversion: 5% (10 sales). AOV: ₹2,500. Revenue: ₹25,000. Cost: ₹3,000. ROI: 733%.
Monthly newsletter (SaaS)
List: 5,000. Open: 30% (1,500). CTR: 4% (60). Trial signups: 10% (6). LTV: ₹15,000. Revenue attributed: ₹90,000. Cost: ₹5,000. ROI: 1700%.
Low-engagement list
List: 20,000 but 10% open rate (2,000). CTR: 1.5% (30). Conversion: 2% (0.6 sales — basically zero). This signals a list hygiene problem, not a copy problem.
Frequently Asked Questions
Still have a question? Our team replies within a business day.
Email ROI above 500% (₹5 return per ₹1 spent) is good. Best-in-class campaigns return 2000–4000%. If your ROI is under 100%, focus on list segmentation and subject line testing first.
Three levers: improve subject lines (raises open rate), improve CTA clarity (raises CTR), or improve landing page (raises conversion rate). Targeting (segmentation) affects all three simultaneously.
Yes. An hour of your time at ₹1,000/hr is a real cost. Most small business owners undercount this and overstate ROI.
B2C: 20–25%. B2B: 25–35%. Anything under 15% signals deliverability or list quality issues. Check spam folder placement and unsubscribe from inactive subscribers.
Absolutely. Email reaches users directly in their inbox without algorithm interference, has zero incremental cost per send on most plans, and works across all device types including feature phones via SMS fallback.
