Simple order estimate
Estimated order profit = selling price − product cost − platform and payment fees − shipping paid by seller − packaging − other order costs. Estimated margin = estimated profit ÷ selling price × 100.
Costs sellers often forget
- Marketplace listing, transaction, payment processing, or currency conversion fees.
- Discounts, refunds, returns, replacements, and chargebacks.
- Advertising, labor, storage, and shipping supplies.
- Sales tax or VAT handling, where applicable to your business.
Check what a fee is based on
A marketplace may calculate fees on more than the item price, or apply fixed charges and category-specific rules. Use the actual fee basis from your sales channel instead of assuming all fees are one percentage.
Keep estimates separate from bookkeeping
This tool helps with a quick planning estimate and is not accounting or tax software. Use your sales records and a qualified adviser for business reporting and tax decisions.
