Sales Funnel Demo Conversion Calculator
Estimate how many customers and how much revenue your sales funnel can generate from leads, demo bookings, close rate and average deal value.
Overview
The Sales Funnel Demo Conversion Calculator helps you estimate how many demos, customers and revenue your funnel can produce from a given number of monthly leads. Enter your lead volume, lead-to-demo rate, demo-to-sale rate and average deal value to get a quick view of funnel performance.
How it works
This calculator follows a simple funnel model. It first multiplies your monthly leads by the lead-to-demo conversion rate to estimate demos. It then multiplies demos by the demo-to-sale rate to estimate customers. Revenue is calculated by multiplying estimated customers by the average deal value. Annual revenue is based on 12 months of the same performance, and the overall conversion rate combines the two conversion steps into one lead-to-customer percentage.
How to use this calculator
- 1Enter the number of leads you generate each month.
- 2Add the percentage of leads that book or attend a demo.
- 3Enter the percentage of demos that turn into paying customers.
- 4Input your average deal value.
- 5Review your estimated demos, customers, monthly revenue and annual revenue.
Example Calculation
Monthly leads
1000
Lead to demo rate
12%
Demo to sale rate
25%
Average deal value
$2,500
Average sales cycle
30
Estimated monthly customers
30
With 1000 monthly leads, a 12% lead-to-demo rate and a 25% demo-to-sale rate, the funnel would generate about 120 demos, 30 customers and 75000 in monthly revenue, or about 900000 per year.
Frequently asked questions
What does this calculator estimate?
It estimates how many demos, customers and how much revenue your sales funnel may generate from your monthly lead volume and conversion rates.
How is the overall conversion rate calculated?
It multiplies the lead-to-demo rate by the demo-to-sale rate to show the combined percentage of leads that become customers.
Can I use this calculator for B2B or SaaS sales funnels?
Yes. It is suitable for many sales funnels where leads book demos and some of those demos become paying customers.
Why does the annual revenue projection differ from actual yearly revenue?
The calculator assumes every month performs the same. In practice, lead volume, conversion rates and deal values can change throughout the year.
Does the sales cycle affect the calculation?
Not directly in this version. It helps provide context for how long conversions may take, but the main estimates are based on volume, conversion rates and deal value.
