First, some clarification of terms:
Margin, also referred to s gross margin, is the difference between cost and selling price. When expressed as a percentage, it is the percentage of the sale price that is (gross) profit.
Markup is the amount that must be added to the cost of an item to determine its sale price. when expressed as a percentage, it is the percentage of the cost price needed to attain the desired gross margin.
Because the markup amount and the margin amount are the same, percent markup is always greater than percent margin.
For a more detailed article regarding margin and markup, see What is the difference between margin and markup at AccountingTools.com
Suppose you had a product that cost you $75, and you wanted to sell for $100, for a gross margin of 25% (of $100)
To achieve that margin, you will need a $25 markup of the cost ($75), or 33,3%
Here are the calculations:
In each row, B is the cost price, C is the margin or markup percentage and D is the retail (sale) price. The two cells with numbers ar the known values. The unknown value shows the formula needed to get the unknown result. The same formula is entered into column D, and calculates the result shown. Column E contains labels naming what has been calculated on that row.
The four formulas are repeated in copyable text below the table.
D2: retail price from cost price and markup %: B2×(1+C2)
C3: margin % from Retail and Cost prices: (D3−B3)÷D3
C4: Markup % from cost and retail prices: (D4−B4)÷B4
D5: Cost price from retail price and margin %:: D5−(C5×D5)
