How to read the result

What it means: The displayed value is an estimate based on your inputs. It represents the calculated scenario under current assumptions, not a guaranteed amount.
Next step: Use the result as a starting point. Adjust parameters to compare scenarios and validate with a professional when needed.
Calculation limits: The model uses simplified formulas and cannot account for all variables in your specific case (local regulations, personal conditions, temporal changes).

Methodology

This calculator computes: revenue = selling price × units sold; subtracts COGS, FBA fees (percent + fixed per unit), referral fees, shipping and other costs; applies tax to positive pre-tax profit to produce net profit.

Assumptions: FBA and referral fee rates must be set by the user to match category and marketplace. Results are estimates for planning — consult accounting/tax professionals for filings.

Glossary+

Revenue: Total sales value = selling price × units sold.
COGS: Cost of goods sold — direct cost to produce or purchase each unit, including inbound shipping to Amazon.
FBA fee: Fulfillment fee charged by Amazon for storage and fulfillment. Can include percent-based and per-unit charges.
Referral fee: Amazon's marketplace fee charged as a percentage of the item price (varies by category).
Profit before tax: Revenue minus all operating costs and fees, before applying taxes.
