Sales Funnel Lead Generation Calculator
Estimate how many leads, customers, revenue and profit your sales funnel could generate based on traffic, conversion rates and average sale value.
Overview
The Sales Funnel Lead Generation Calculator helps you estimate how many leads and customers your funnel could produce from your monthly traffic. Enter your visitor volume, visitor-to-lead rate, lead-to-customer rate, average sale value, visitor acquisition cost and gross margin to see projected revenue and profit.
How it works
This calculator follows a simple funnel model. It first estimates leads by multiplying monthly visitors by your visitor-to-lead conversion rate. It then estimates customers by applying your lead-to-customer conversion rate to those leads. Revenue is calculated from customers multiplied by average sale value. Marketing cost is based on your cost per visitor, and net profit is estimated by applying gross margin to revenue and subtracting marketing cost.

Example Calculation
Monthly Visitors
10000
Visitor to Lead Conversion Rate
8%
Lead to Customer Conversion Rate
15%
Average Sale Value
$500
Cost per Visitor
$2
Gross Margin
60%
Estimated Leads
800
With 10,000 monthly visitors, an 8% lead conversion rate and a 15% close rate, the funnel would generate about 800 leads and 120 customers. At an average sale value of $500, that equals roughly $60,000 in revenue and about $21,000 in estimated net profit after marketing.
Frequently asked questions
What does this calculator estimate?
It estimates monthly leads, customers, revenue, marketing cost, customer acquisition cost and net profit based on your funnel assumptions.
What is a good visitor to lead conversion rate?
That depends on your traffic source, offer and landing page quality. Many funnels improve performance by testing messaging, forms and calls to action.
What is lead to customer conversion rate?
It is the percentage of leads that become paying customers after your sales or follow-up process.
Does this calculator include repeat purchases?
No. It focuses on new-customer funnel performance unless you manually increase average sale value to reflect additional revenue.
How should I enter cost per visitor?
Use your average marketing spend per visitor across the channels driving traffic to the funnel.
Why is net profit only an estimate?
Because real business results can vary based on fulfillment costs, traffic quality, refunds, discounts, sales cycle length and other operating expenses.
