This tool acts as monthly forecast and projection calculator for your eBay business. It takes your sell-through rate and average sale price, scaling them across the exact days of each month to simulate a day-by-day inventory expansion that projects your sales and revenue over a 12 month timeline.
To help you structure an actionable eBay business plan, the system supports 3 modes:
First, we must measure how fast your items sell. This is called your sell-through rate (STR). If you sold 300 items over 90 days out of 1,000 active listings, your sales speed is 30% for 90 days. To ensure an "apples-to-apples" comparison across all months, we standardise this to a clean 30 day equivalent, which would be 10% per month.
You list items weekly, but months have different lengths (e.g. 31 days in January vs. 28 days in February). We divide your weekly listing quota by 7 to determine your daily pace, then scale it to the number of calendar days in each month. This keeps your inventory projection aligned with actual world calendars.
In an eBay store, you do not list all of your new items on the first day of the month, nor do they sit idle until the last day. Sourcing, listing, and selling are continuous. To ensure an accurate mathematical projection, this calculator computes your sales using your average inventory levels during that month, rather than just the starting or ending stock levels.
Once we establish the ending inventory, we subtract it from your total stock to determine the number of units sold, then multiply by your Average Sale Price (ASP) to calculate your gross monthly revenue.
No mathematical model can predict e-commerce behavior with absolute certainty. Keep these critical store metrics and factors in mind as you plan your eBay growth strategy:
