Markup adds a percentage of cost to that cost. If the included cost is PKR 600 and markup is 50%, the resulting price is PKR 900. The PKR 300 difference is one third of revenue, so the margin is 33.33%.
The Whatson Markup Calculator shows price, profit and resulting margin together. It is useful when a supplier or internal price list is expressed on a cost plus basis.
Build the cost basis before applying the percentage
Enter the included unit cost and the markup percentage. A product cost alone gives a price based only on that product cost; a fuller landed and handling cost gives another price.
Keep comparable products on the same cost basis. Applying the same markup to one product’s supplier cost and another product’s landed cost does not create a like for like comparison.
The checked 50% example
For an illustrative PKR 600 included cost and 50% markup, the formula is 600 × (1 + 50/100) = PKR 900.
The checked profit is PKR 300. Margin is 300 ÷ 900 × 100 = 33.33%. The calculator has not taken a marketplace fee, shipping subsidy or output tax out of that amount unless you already included it in the cost basis.
The preset buttons offer example markups of 25%, 50% and 100%. They populate an input; they do not recommend a markup for your product category.
The same percentage can mean different prices
A 50% margin target would require PKR 1,200 revenue from PKR 600 cost before other deductions. A 50% markup produces PKR 900 instead.
Profit Margin Calculator can check either completed price against cost. Target Selling Price Calculator is the better worksheet when percentage selling fees must be allowed for while solving a margin target.
Revenue based charges cannot be hidden in a guessed markup
A fee calculated on the final selling price changes when that price changes. Treating it as a fixed amount in the cost field can give a misleading result unless the assumed amount matches the final quote.
The target price tool handles that relationship explicitly. This markup worksheet keeps the cost plus calculation simple and does not infer a platform’s charge structure.
Record the policy as well as the number
Save the markup percentage, included costs and product description together. A note saying “PKR 900” cannot explain whether the price arose from markup, margin or a market comparison.
Use your own current supplier and operating costs before issuing a quote. A mathematically reproducible markup is a pricing input, not evidence that customers will buy at that price or that every business expense has been covered.
