eBay Watcher Conversion Calculator

Estimate how many eBay watchers may turn into buyers and the revenue and profit that could result from your listing performance.

Your Details

Overview

The eBay Watcher Conversion Calculator helps you estimate how many watchers on a listing may become buyers. Enter your watcher count, expected conversion rate, average sale price, item cost and selling fees to get a quick estimate of sales, revenue and profit.

How it works

This calculator multiplies your watcher count by your expected conversion rate to estimate the number of sales. It then calculates gross revenue using your average sale price, subtracts percentage-based and fixed fees, and subtracts your item cost to estimate profit. The profit margin is calculated as profit divided by revenue.
