eBay Bulk Purchase Profit Calculator
Estimate your profit, profit margin, and return on investment when buying items in bulk to resell on eBay.
Overview
Use this eBay Bulk Purchase Profit Calculator to estimate whether a wholesale or job lot purchase is worth reselling. Enter the number of items, your total bulk cost, expected sale price, eBay fee rate, and per-item shipping and other costs to see estimated profit and margin.
How it works
The calculator estimates total revenue by multiplying the number of items by the expected sale price per item. It then estimates eBay fees as a percentage of revenue and adds those fees to your bulk purchase cost, shipping costs, and other per-item expenses. Net profit is revenue minus total costs. Profit margin is net profit divided by revenue, and ROI is net profit divided by the original bulk purchase cost.

Frequently asked questions
What does this eBay bulk purchase calculator estimate?
It estimates your total profit, profit per item, profit margin, ROI, and total cost when buying items in bulk to resell on eBay.
Does this calculator include eBay fees?
Yes. You enter an estimated fee percentage, and the calculator applies it to your total sales revenue.
Should I include shipping in the sale price or as a cost?
If you offer free shipping, include postage and packaging in the shipping cost per item. If buyers pay shipping separately, you may want to adjust your expected sale price or costs to reflect your actual setup.
Does it account for unsold items or returns?
No. It assumes all items sell at the expected average sale price unless you adjust your inputs to allow for losses.
What other costs should I include?
You can use other cost per item for expenses such as cleaning, testing, inserts, labels, storage, and similar variable costs.
How can I use this calculator to compare deals?
Run the numbers for different bulk lots using the same expected selling price and cost assumptions. The higher profit and margin may indicate the better deal.
