Sales Funnel Revenue Calculator
Estimate revenue from your sales funnel using visitor volume, conversion rates and average order value.
Overview
The Sales Funnel Revenue Calculator helps you estimate how much revenue your funnel could produce from visitor volume, stage-by-stage conversion rates, average order value and optional marketing spend. It is useful for planning campaigns, setting targets and comparing funnel performance over time.
How it works
The calculator moves people through your funnel one stage at a time. First it estimates leads from total visitors, then opportunities from leads, and then customers from opportunities. It multiplies the final customer estimate by average order value to project revenue. If you include marketing spend, it also estimates return on marketing spend and cost per lead.

Frequently asked questions
What does this calculator estimate?
It estimates how many leads, opportunities, customers and how much revenue your funnel may generate from the traffic and conversion rates you enter.
Can I use this calculator for monthly or annual planning?
Yes. You can use any time period as long as your visitor count, conversion rates, order value and spend all relate to the same period.
What is average order value?
Average order value is the average revenue you earn from each completed sale or customer transaction.
Why are there multiple conversion rates?
Sales funnels usually have several stages. Breaking the funnel into separate rates helps you see where performance is strongest or weakest.
What does return on marketing spend mean here?
It shows how many units of revenue are generated for each unit of marketing spend based on your inputs. It is a simple revenue multiple, not profit.
Does this calculator account for refunds or repeat purchases?
