Method and limitations

Margin = profit ÷ price; markup = profit ÷ cost. Target price = cost ÷ (1 − margin), or cost × (1 + markup). The invoice price is rounded to cents; displayed ratios use that price. A zero denominator gives an undefined rate.

Taxes assume a fully taxable sale at the selected province’s general rates. Taxes are not profit. Excise taxes, exemptions, complex discounts, payment fees and automatic allocation of fixed costs are excluded.
