Selling Price Calculator

Enter what one unit costs you and the markup you want. The calculator returns:

• Selling price: cost × (1 + markup ÷ 100)
• Profit: selling price − cost
• Profit margin: profit ÷ selling price × 100

With the defaults, a $25 cost and a 60% markup give a $40 selling price, $15 of profit and a 37.50% margin.

The tool asks for a markup, not a margin. If your plan is written as a margin, convert it first with markup = margin ÷ (100 − margin) × 100. For a 45% margin on the $25 item, that is 81.82%, which gives a $45.46 price and a margin line of 45.00%. Check the margin line every time; it is the quickest way to catch a margin typed into the markup field.

A percentage fee taken at checkout comes out of the price, so it eats into the margin the calculator shows. Take the $40 price from above and a 2.9% + $0.30 card fee: the fee is $1.46, profit drops from $15 to $13.54 and the margin from 37.50% to 33.85%.

To keep a target margin after fees, price with:

price = (cost + fixed fee) ÷ (1 − target margin − fee rate)

For the $25 item, a 37.5% margin and that fee: ($25 + $0.30) ÷ (1 − 0.375 − 0.029) = $42.45. Check: the fee on $42.45 is $1.53, leaving $15.92 of profit, which is 37.5% of the price. To get the same result from this calculator, enter the $25 cost and a 69.80% markup.

Sometimes the price is fixed by competitors and the question is what you can afford to pay a supplier. Divide the price by one plus your markup:

maximum cost = market price ÷ (1 + markup ÷ 100)

If similar products sell for $39.99 and you need a 60% markup, the most you can pay is $39.99 ÷ 1.6 = $24.99. Enter $24.99 at 60% and the calculator shows $39.98. Bring that figure into supplier negotiations: any quote above it means a lower markup or a higher price.

Rounding to a price ending also moves the margin. Starting from the $25 cost:

A single markup gives every item the same margin, but very different dollars of profit. That matters once each order carries a fixed cost, such as packaging and a per-order fee. Here is a 60% markup on three items, with $1.80 of fixed cost per order:

The calculator shows 37.50% for all three. The cheap item barely pays for its own handling. Either use a higher markup on low-cost items, add the per-order cost to the unit cost before marking up, or sell them in bundles. The calculator writes the price with a trailing zero dropped, so $6.40 appears as $6.4.
