eBay Monthly Profit Calculator
Estimate your monthly eBay profit after product costs, shipping, selling fees and ad spend.
Overview
The eBay Monthly Profit Calculator helps you estimate how much profit you keep each month after typical selling costs. Enter your monthly sales volume, average sale price, product cost, shipping cost, eBay fee rate, ad spend rate and fixed monthly expenses to see your estimated profit and margin.
How it works
This calculator starts by estimating your monthly revenue from items sold multiplied by average sale price. It then subtracts the main costs of selling on eBay, including cost of goods, shipping and packing, eBay fees, ad spend and fixed monthly costs. Profit margin is calculated by dividing monthly profit by monthly revenue, giving you a simple view of how efficiently your sales are turning into profit.

Frequently asked questions
What does this eBay Monthly Profit Calculator estimate?
It estimates your monthly revenue, total selling costs, eBay fees, profit and profit margin based on your average monthly sales inputs.
Should I include shipping in the sale price or as a separate cost?
Use the average amount the buyer pays as the sale price, then enter your own average shipping and packing cost separately so your profit estimate reflects fulfilment costs.
Do eBay fees always match the fee rate I enter?
Not always. Actual fees can vary by category, account type, promotions and any additional charges, so using an average fee rate is usually the simplest approach.
Can this calculator include promoted listings costs?
Yes. Enter your average promoted listings or ad spend percentage in the ad rate field to include advertising costs in the estimate.
Does this calculator include returns and refunds?
No. If returns or refunds are a regular part of your business, you may want to increase your costs or reduce your average sale assumptions to allow for them.
What is a good profit margin for eBay selling?
That depends on your category, sourcing method, shipping costs and business model. The calculator helps you compare scenarios and see how changes affect your margin.
