Calculate markup percentage and selling price based on product cost.
This Markup Calculator helps you set the right selling price for any product based on your cost and desired markup percentage. Enter your product cost, markup rate, and monthly sales volume to instantly see the selling price, profit per unit, profit margin, and projected monthly revenue and profit. Use it to price products correctly, compare markup rates, and understand the difference between markup and margin.
Every product you sell needs to be priced to cover its cost, contribute to your overheads, and leave something behind as profit. The markup percentage is the mechanism that connects cost to selling price — and getting it wrong, even slightly, compounds across every unit you sell. Too low a markup and the business slowly bleeds. Too high and you price yourself out of the market. This calculator makes the arithmetic instant so every pricing decision starts from the right number.
Markup is the percentage you add to a product's cost to arrive at its selling price. If a product costs $50 and you apply a 40% markup, you add $20 — and the selling price becomes $70. The formula is: Selling Price = Cost + (Cost × Markup ÷ 100).
Where most sellers go wrong is treating these two figures as interchangeable. They are not the same thing, even though both are expressed as percentages and both relate profit to price and cost.
Calculated against cost. A 40% markup on a $50 product means profit is 40% of $50, which is $20. The selling price becomes $70.
Calculated against selling price. On that same product — sold at $70 with $20 profit — the margin is $20 ÷ $70 = 28.6%. A 40% markup produces only a 28.6% margin.
These numbers are fundamentally different, and using one when you mean the other produces systematic errors in your pricing. This calculator shows both simultaneously so you always have both figures in front of you when making pricing decisions.
If you have a target margin in mind, you can work backward to find the markup you need. The formula is: Required Markup = Margin ÷ (1 − Margin)
A 100% markup — doubling the cost — produces only a 50% margin, not a 100% margin. Understanding this conversion is essential for anyone setting prices with a margin target in mind.
The dollar amount you earn from each unit sold above the product cost. At a 40% markup on a $50 product, profit per unit is $20 — the per-unit contribution that goes toward overheads and building profit.
The price you charge the customer — cost plus the markup amount. This is the number that goes on the product listing, the shelf, or the invoice.
What percentage of the selling price is profit. Seeing markup and margin side by side immediately shows that a seemingly high markup translates to a more modest margin — the relationship that catches most people out.
Selling price multiplied by monthly units sold — the gross top-line figure. Alongside monthly profit, it tells you how much of your revenue converts to actual profit at your current markup.
Profit per unit multiplied by monthly units sold. A small profit per unit can be an excellent business at high volume. Monthly profit brings both dimensions together into a single number.
Keystone pricing
A 100% markup that doubles the cost — historically the default in retail. It produces a 50% gross margin, sufficient to cover rent, staff, and overhead in traditional retail environments. Online and direct-to-consumer businesses often operate with higher markups because their overhead structure is different.
Cost-plus pricing
Starts from your fully loaded cost — not just the product cost, but your allocated share of shipping, storage, fulfillment, and overhead — and adds a target markup on top. The key is using the fully loaded cost, not just the raw product cost.
Competitive pricing
Works backward from the market price. If the market price is $80 and your product cost is $35, your inherent markup is 128.6% and your margin is 56.3%. Whether that is acceptable depends on what costs you need to cover.
Value-based pricing
Sets the price based on what the customer is willing to pay rather than what the product costs to make. In this model, markup is a consequence of the pricing decision rather than a driver of it.
Applying markup to the wrong cost base
The cost base needs to include every expense tied to getting that unit ready to sell — freight, duties, inspection, packaging, and storage all count. When these are not included, the effective markup and margin are much lower than the calculation suggests.
Confusing markup with margin in target-setting
A business targeting a 40% margin that calculates 40% markup will consistently underprice every product. A 40% margin requires a 66.7% markup — significantly higher. Running this calculator with both figures visible prevents this from compounding across an entire catalogue.
Using a flat markup for every product regardless of category
A commodity product where price comparison is easy requires a tighter markup. A differentiated product with unique features can support a higher markup. A single blanket markup rate ignores these differences.
Not adjusting markup when costs change
If a supplier increases cost, the same markup percentage produces a higher selling price — which may not be acceptable in your market. Running the numbers through this calculator when costs change tells you exactly what the impact is before you make a decision.

A tool that takes your product cost and desired markup percentage and immediately returns your selling price, profit per unit, profit margin, and monthly figures — so pricing decisions take seconds rather than requiring a spreadsheet.
Subtract the cost from the selling price to get profit, then divide that profit by the cost and multiply by 100. A product costing $50 that sells for $70 has a $20 profit — divide $20 by $50 to get 0.40, multiply by 100, and the markup is 40%.
Because they measure different things from different starting points. Markup divides profit by cost — margin divides the same profit by the selling price. Price a product at $70 with a $50 cost and your markup is 40% but your margin sits at 28.6%. The denominator changes, so the percentages will always differ — and the higher your markup, the bigger that gap becomes.
It depends on your cost structure and industry. Retail businesses typically need 40% to 100% markup to cover overhead and still land a healthy margin. Digital products and software can support much higher markups because the variable cost per unit is near zero. Start by calculating your fully loaded cost — including freight, storage, and fees — then apply a markup that leaves enough margin after all downstream expenses.
A 100% markup that doubles the cost to arrive at the selling price. It produces a 50% gross margin and has historically been the standard in retail because it provides enough room to cover rent, staff, and returns. Many online sellers use higher markups because their cost structures and sales volumes differ from traditional retail.
Use this formula: Required Markup = Margin ÷ (1 − Margin). To hit a 40% margin, divide 0.40 by 0.60 — the required markup is 66.7%. To hit 50%, divide 0.50 by 0.50 — you need a 100% markup, meaning you double the cost.
Your selling price rises if you keep the same markup percentage, which may put you above what the market will accept. Run the new cost through this calculator to see the impact on both selling price and margin before deciding whether to absorb the increase, adjust your price, or negotiate with the supplier.
