Provides a clear side-by-side comparison of Gross Margin % (profit based on selling price) and Markup % (profit based on cost price) to eliminate pricing confusion.
Gross Profit Margin measures the proportion of revenue retained as profit after accounting for the direct Cost of Goods Sold (COGS).
The fundamental pricing formulas computed by this tool are:
\(\text{Gross Profit} = \text{Revenue (Selling Price)} - \text{Cost of Goods Sold (COGS)}\)
\(\text{Gross Margin (\%)} = \left(\frac{\text{Gross Profit}}{\text{Revenue}}\right) \times 100\)
\(\text{Markup (\%)} = \left(\frac{\text{Gross Profit}}{\text{COGS}}\right) \times 100\)
\(\text{Required Selling Price} = \frac{\text{COGS}}{1 - \frac{\text{Target Margin}}{100}}\)
A common mistake in pricing is confusing margin with markup. A 50% markup on a $100 cost item results in a $150 selling price, which yields a 33.33% gross margin.
