Most B2B founders know their email list should be making them money. Few know exactly how much.
This calculator shows you the gap between where you are and where you should be — so you can stop guessing and start building.
Step 1: Your Current Numbers
Fill in these 4 numbers:
Metric | Your Number |
|---|---|
A. Total email list size | |
B. Average monthly emails sent | |
C. Average open rate (%) | |
D. Average offer/product price ($) |
Step 2: Your Current Email Revenue
Monthly email-attributed revenue: $________
If you don't know this number, you're not alone. Most B2B companies don't track it. Write "$0" and keep going — that's exactly why this calculator exists.
Step 3: Calculate Your Revenue Potential
Use the benchmarks below based on what I've seen across 200+ B2B clients:
Benchmark Open Rates (what's achievable)
List Size | Average B2B | Top Performers (what we aim for) |
|---|---|---|
Under 5K | 35-45% | 50-60% |
5K-25K | 30-40% | 45-55% |
25K-50K | 25-35% | 40-50% |
50K+ | 20-30% | 35-45% |
The Revenue Formula
Your potential monthly email revenue =
List Size (A) × Active Rate × Conversion Rate × Average Price (D)
Let's run three scenarios:
Scenario 1: Basic (Consistent Sending Only)
Just sending a weekly email with a clear CTA.
Active subscribers: A × 30% = _______
Monthly click-throughs: Active × 3% CTR = _______
Monthly conversions: Click-throughs × 2% conversion = _______
Monthly revenue: Conversions × D = $_______
Scenario 2: Optimized (Welcome Sequence + Weekly Sends)
Welcome sequence + weekly newsletter + one sales sequence.
Active subscribers: A × 45% = _______
Monthly click-throughs: Active × 5% CTR = _______
Monthly conversions: Click-throughs × 3% conversion = _______
Monthly revenue: Conversions × D = $_______
Scenario 3: Full Revenue Engine (What we build for clients)
Welcome + nurture + behavior-triggered sales + reactivation + weekly newsletter.
Active subscribers: A × 55% = _______
Monthly click-throughs: Active × 7% CTR = _______
Monthly conversions: Click-throughs × 5% conversion = _______
Monthly revenue: Conversions × D = $_______
Step 4: Find Your Revenue Gap
Your Revenue Gap = Scenario 3 Revenue - Current Revenue
Revenue Gap: $_______ per month
Annual Gap: $_______ per year
Real Examples
Client Type | List Size | Before | After (90 days) | Revenue Gap Closed |

B2B Coach | 8,000 | Sporadic revenue | 25% of total revenue | Ongoing predictable income |
Education Company | 11,000 | 22% open rates | 54% open rates | 2.5x engagement, consistent pipeline |
