Sales Funnel Net Margin Calculator
Estimate net profit and net margin from your sales funnel using traffic, conversion rates, average order value, and costs.
Overview
The Sales Funnel Net Margin Calculator helps you estimate how profitable your funnel is by combining traffic, lead conversion rate, sales conversion rate, average order value, advertising spend, and operating costs. It is useful for checking whether your funnel is generating enough revenue to cover direct and fixed costs.
How it works
The calculator estimates leads from visitors and lead conversion rate, then estimates customers from leads and sales conversion rate. Revenue is calculated by multiplying customers by average order value. Total costs are the sum of advertising spend, variable costs per sale across all customers, and fixed costs. Net profit is revenue minus total costs, and net margin is net profit divided by revenue, shown as a percentage.

With 10,000 visitors, a 25% lead conversion rate, and an 8% sales conversion rate, the funnel produces about 200 customers. At an average order value of $120, revenue is about $24,000. After $3,000 in ad spend, about $7,000 in variable costs, and $1,000 in fixed costs, net profit is about $13,000 and net margin is about 54.2%.
