How it works

  • Landed cost = ex-factory cost converted to baht + freight + import duty (+ import VAT if you cannot reclaim it).
  • Net revenue = shelf price divided by (1 + VAT) if you are VAT-registered and the price includes VAT; otherwise the shelf price.
  • Profit = net revenue minus landed cost, commission, payment fee, fulfillment, advertising and returns.
  • Break-even ROAS = 1 divided by your margin before advertising. Below this return on ad spend, each order loses money.
  • Minimum price solves the same equation for the shelf price that delivers your target margin.
  • This is a simplified model for planning and not tax advice. Rates and rules vary by product and change over time; confirm with a qualified adviser.
