For sellers and importers

Free Calculators

Three focused calculators for the questions that come before a pricing or buying decision. Each answers one question from the numbers you enter, with nothing estimated for you. One free MarginGuides account works for all of them, with unlimited calculations and no credit card.

One free account for every calculator

Every calculator works the same way: enter your numbers, then see the result with a free MarginGuides account. One account works for all of them, with no limit on how often you calculate and no credit card. Creating an account is free and does not start a paid subscription.

During the Public Beta, the same free account also gives you full access to the MarginGuides app, including Analyze and the decision tools.

Your numbers, nothing estimated

The calculators use only the amounts you enter. They never look up a duty or tariff rate, an exchange rate or a marketplace fee, never add a cost because of an Incoterm or a country, and work with prices excluding VAT or sales tax. Your inputs are not put in the page address and are kept only in this browser tab while you work.

Which calculator do I need?

  • Pricing a product or checking a marketplace listing: start with the profit margin calculator. To see what goes into a real margin, read how to calculate true profit margin before selling.
  • Planning ads: the break-even advertising calculator shows the return on ad spend a product needs before advertising costs you money.
  • Importing stock: the landed cost calculator turns a supplier quote and the shipment costs into a cost per unit. See landed cost vs product cost.

Each answers one question. For the full decision - target prices, tax, customs, returns, exchange rates and how far costs can move - use the MarginGuides Decision Engine: Analyze and the decision tools.
