Your Details

Overview

A sales funnel optimisation calculator helps you estimate how improvements in traffic, lead conversion and sales conversion could affect your monthly customers and revenue. Enter your current funnel metrics and expected uplift percentages to compare current and projected performance.

How it works

The calculator starts with your current monthly visitors, then applies your visitor to lead conversion rate to estimate leads and your lead to customer conversion rate to estimate customers. Revenue is calculated by multiplying customers by average order value. It then applies your expected improvement percentages to traffic and conversion rates to estimate an optimised funnel and compares the projected revenue with your current revenue.
