How to use this calculator
- Enter what the item has cost you and the profit you need.
- Enter commission and processing percentages.
- Open the offer comparison section, enter buyer proposals, and compare profit rather than looking only at the headline offer.
How the estimate works
The minimum price formula is (fully loaded cost + desired profit) ÷ (1 − combined percentage fee rate). It works when the combined percentage fees are below 100%.
Fixed fees should be added to overhead or the item-cost fields. Do not enter the same expense twice.
Frequently asked questions
Is the minimum selling price the same as market value?No. It is your financial floor. The market may support a higher price or force you to reconsider your costs.
Why does the fee rate change the minimum price?A percentage of every dollar goes to fees, so the asking price must be high enough to leave the required net amount.
What costs belong in overhead?Allocate a reasonable share of rent, storage, utilities, insurance, and other recurring costs, while avoiding double-counting.
Should I always reject an offer below the minimum?Not necessarily. A quick cash sale or reduced storage burden may matter, but compare those benefits explicitly with the loss in profit.
Can I include taxes?This tool is for dealer economics. Sales tax collected for a tax authority generally should not be treated as dealer profit; use a tax tool for checkout calculations.
