Sales Funnel Traffic Calculator
Estimate how much website traffic you need at each stage of your funnel to reach a target number of customers or revenue.
Overview
The Sales Funnel Traffic Calculator helps you work backward from a customer or revenue goal to estimate how much traffic you need at each stage of your funnel. Enter your average order value and your visitor-to-lead, lead-to-opportunity, and opportunity-to-customer conversion rates to see the volume required.
How it works
This calculator starts with your end goal and works backward through the funnel. If you enter a revenue target, it first divides revenue by average order value to estimate how many customers are needed. It then divides that customer target by each stage conversion rate to estimate the opportunities, leads and visitors required at the top of the funnel.
How to use this calculator

- 2Enter your target number of customers or target revenue.

A revenue goal of 10000 with a 200 average order value means you need 50 customers. With the example conversion rates, that works out to about 8334 visitors, 417 leads and 84 opportunities.
Frequently asked questions
What does the Sales Funnel Traffic Calculator estimate?
It estimates how many visitors, leads and opportunities you need to reach a target number of customers or a revenue goal.
Can I use a revenue target instead of a customer target?
Yes. If you choose a revenue goal, the calculator converts that amount into a customer target using your average order value.
Why do small conversion rate changes affect traffic so much?
Because each funnel stage compounds the next one. A small improvement in one conversion rate can reduce the total traffic needed significantly.
What is a good visitor to lead conversion rate?
That depends on your traffic source, offer, audience and landing pages. Use your own historical data where possible for a more useful estimate.
Should I include repeat purchases in average order value?
This version is best used with the average value of a typical sale or customer conversion. If repeat purchases matter, use a value that reflects that behavior.
Can I use this for B2B and B2C funnels?
Yes. The calculator is generic and works for both, as long as your conversion rates and average order value reflect your own funnel.
