Markup is a pricing tool expressed as a percentage that represents the ratio of profit to cost. It tells you how much you are adding on top of your production or purchase cost to arrive at your final selling price. For example, a 50% markup means you take your cost (say, $100) and add 50% of that cost ($50) to the final price ($150). It ensures that every sale covers the direct cost of the item plus a contribution towards your overhead and net profit.

The difference is mathematical and strategic. Markup is calculated based on the Cost Price (Profit ÷ Cost), whereas Margin is based on the Revenue or Selling Price (Profit ÷ Revenue). Because Revenue is always higher than Cost (assuming you made a profit), the Margin percentage will always be lower than the Markup percentage for the same transaction. For instance, selling a $100 item for $200 is a 100% Markup, but only a 50% Margin. Retailers use markup to set prices, but accountants use margin to measure profitability.

To calculate the markup percentage, first determine your gross profit by subtracting the cost price from the selling price. Then, divide that profit by the original cost price. Finally, multiply the result by 100 to get the percentage. The formula is: ((Selling Price - Cost Price) / Cost Price) × 100. This simple calculation allows you to standardize your pricing strategy across different products with varying costs, ensuring a consistent return on investment for your inventory.
