Margin, break-even, ROI, ROAS, CAC, CLV and commission formulas are the same in the US, UK, EU, Australia, Canada and India. What changes is the currency and whether GST, VAT or sales tax sits inside the price you typed. Say which costs you included before you compare two campaigns or two prices.

A worked check

Sell at 100, spend 60 on the product and 10 on ads, and profit is 30. Margin is 30%. ROAS on the ads is 100 / 10 = 10, which can look excellent while the margin is ordinary. Add 20% VAT on a VAT-exclusive price and the customer pays 120, but that 20 is not profit.
