Markup Price Calculator
Turn a cost and markup percentage into a selling price, round it to a .99, .95 or whole-dollar ending and see the profit and margin.
Markup pricing starts from what an item costs you and adds a percentage of that cost on top. It is the quickest way to price stock consistently, and most shops then round the result to a familiar price ending. This calculator gives the marked-up price, rounds it if you want, and shows the profit, the markup you actually end up with and the gross margin.
How to use this tool
- Enter the cost of one unit.
- Enter the markup percentage you want to add.
- Choose a price ending, or keep the exact price.
- Enter a number of units to see the revenue and profit for a whole batch.
Formula
Selling price = Cost × (1 + Markup ÷ 100)
Actual markup = (Price − Cost) ÷ Cost × 100
Gross margin = (Price − Cost) ÷ Price × 100
Price-ending rounding goes upward; a price already at the selected ending stays unchanged. Exact mode retains fractional cents internally even though the currency display rounds them. Totals use that internal value. The comparison table always uses unrounded prices.
Example
An item costs $24. A 50% markup adds $12 for a price of $36.00, which is a 33.33% gross margin. Rounding up to a .99 ending gives $36.99, a $12.99 profit and an actual markup of 54.13%. Selling 100 units at that price brings in $3,699 and $1,299 of gross profit.
Frequently asked questions
What markup should I use?
Choose a rate that covers the costs you include, overhead and your desired return, then compare the resulting price with your market. A 100% markup doubles cost and is called keystone pricing; this is a convention, not a recommended margin.
Is a 50% markup a 50% profit margin?
No. A 50% markup gives a 33.3% margin, because margin divides the same profit by the higher selling price. To reach a 50% margin you need a 100% markup.
Why round prices up to .99?
Prices ending in .99 or .95 are a retail convention many shoppers are used to. Whether they lift sales depends on your customers, so the calculator lets you compare the exact and rounded price.
