This calculator totals categories for planning. It does not determine deductibility, depreciation, home office rules, vehicle method, inventory accounting, or filing treatment.
Reconcile expense totals with fee data
Schedule C planning needs marketplace fee totals, but listing decisions need the current fee model behind those totals. Use the Fee Index for same-input marketplace rows, Fee Changes for recent policy updates, and Seller Reports for dated summaries of platform fee pressure.
Use this calculator for grouped expense planning, then cite the data assets when you need a source for the marketplace fee assumptions behind seller records.
Turn this result into a listing decision
Use the tool result as a starting point, then test payout, break-even price, shipping, and marketplace fit before you publish the listing.
What to track
Resellers usually need separate records for gross sales, returns, cost of goods sold, marketplace fees, postage, supplies, mileage, software, and other ordinary business costs. This calculator groups those totals before they go into tax software or a preparer workflow.
It does not decide whether an expense is deductible or where it belongs on your tax return. Use the IRS Schedule C instructions and a tax professional for filing decisions.
