This calculator gives an estimate for planning only and is not financial, accounting or tax advice. A profitable selling price also depends on costs this tool does not capture, such as overhead, shipping, payment fees, returns, discounts and tax, plus what your market will actually pay. Confirm your numbers with full costing and a qualified adviser before setting prices.
A cost-plus pricing calculator sets a selling price by adding a fixed markup percentage on top of what a product costs you. It is the simplest pricing method and a sensible starting point for retailers, makers, freelancers and wholesalers. Enter your unit cost and the markup percent you want, and this cost-plus pricing calculator shows the selling price, the profit you keep per unit, and the profit margin that markup actually produces.
What is the Cost Plus Pricing Calculator?
Cost-plus (or markup) pricing works in one step: take what the item costs you, add a percentage of that cost as markup, and the result is your selling price. The formula is selling price = cost x (1 + markup% / 100). A 50% markup on a $40 cost adds $20, giving a $60 price. The appeal of a cost-plus pricing calculator is that it is fast, transparent and guarantees that every sale covers cost plus a planned profit, as long as your cost figure is complete.
The single most important thing to understand is that markup and margin are not the same number. Markup is the profit measured as a percentage of cost, while margin is the same profit measured as a percentage of the selling price. Because the price is always larger than the cost, the margin is always a smaller number than the markup. A 50% markup gives only a 33.33% margin, and a 100% markup (doubling the cost) gives a 50% margin. Quoting one when you mean the other is one of the most common and expensive pricing errors, which is why this cost-plus pricing calculator shows both side by side.
Cost-plus pricing is used across almost every industry. Retailers convert wholesale unit costs into shelf prices, contractors add a margin to labour and materials, manufacturers price finished goods off their bill of materials, and regulated suppliers sometimes use cost-plus contracts where an agreed markup is added to audited costs. In each case the markup pricing calculator turns a cost you know into a price you can defend, because the profit is built in by design rather than guessed.
Cost-plus pricing has real limits. It ignores what customers are willing to pay and what competitors charge, so it can leave money on the table for a desirable product or price you out of the market for a commodity one. It is also only as good as your cost number: if you mark up the bare purchase cost while forgetting overhead, shipping, packaging, payment-processing fees and an allowance for returns, the margin you think you are earning will be eaten away. Treat the output of the cost-plus pricing calculator as a floor to build on, then sanity-check it against your market.
The fix for those limits is to feed the cost-plus pricing calculator the fullest cost you reasonably can, then compare its selling price against real competitor prices before you commit. Used that way, cost-plus markup gives you a reliable price floor that protects your margin, while market awareness tells you how much headroom you have above that floor. Many sellers price with a markup pricing calculator first and then adjust upward or downward by a few percent to match perceived value.
When to use it
- Setting a retail shelf price by adding a standard markup to your wholesale unit cost.
- Pricing a handmade or print-on-demand product so each sale covers materials plus a target profit.
- Quoting a freelance or service rate by adding a markup to your direct cost of delivering the work.
- Converting a supplier price list into selling prices at a consistent markup across a whole catalog.
- Checking whether a proposed price hits the profit margin you assumed when you set the markup.
- Explaining to a client or partner exactly how a cost-plus contract price was built from cost.
How to use the Cost Plus Pricing Calculator
- Enter the unit cost: what one item costs you, ideally including direct costs like materials and inbound shipping.
- Enter the markup percent you want to add on top of that cost.
- Use a quick-pick button (10%, 25%, 50%, 75%, 100%) if you just want a common markup.
- Read off the selling price, the profit per unit, and the profit margin that markup produces.
- Compare that selling price against competitor prices and adjust the markup if it is too high or too low.
Formula & method
Worked examples
A product costs you $40 and you want a 50% markup.
- selling price = 40 x (1 + 50 / 100) = 40 x 1.5 = 60.00
- profit per unit = 60 - 40 = 20.00
- profit margin = 20 / 60 x 100 = 33.33%
Result: Selling price $60.00, profit $20.00 per unit, margin 33.33%
An item costs $8 and you apply a 60% markup.
- selling price = 8 x (1 + 60 / 100) = 8 x 1.6 = 12.80
- profit per unit = 12.80 - 8 = 4.80
- profit margin = 4.80 / 12.80 x 100 = 37.50%
Result: Selling price $12.80, profit $4.80 per unit, margin 37.50%
You need a 40% profit margin on a $30 cost and want the equivalent markup.
- To hit a margin, divide cost by (1 - margin): price = 30 / (1 - 0.40) = 30 / 0.60 = 50.00
- profit per unit = 50 - 30 = 20.00
- equivalent markup = profit / cost x 100 = 20 / 30 x 100 = 66.67%
Result: Selling price $50.00, a 40% margin needs a 66.67% markup
How a markup percent translates into the profit margin it actually delivers
| Markup on cost | Multiply cost by | Resulting margin |
|---|---|---|
| 10% | 1.10 | 9.09% |
| 25% | 1.25 | 20.00% |
| 50% | 1.50 | 33.33% |
| 75% | 1.75 | 42.86% |
| 100% | 2.00 | 50.00% |
| 200% | 3.00 | 66.67% |
The markup you need to reach a target profit margin
| Target margin | Divide cost by | Required markup |
|---|---|---|
| 10% | 0.90 | 11.11% |
| 20% | 0.80 | 25.00% |
| 30% | 0.70 | 42.86% |
| 40% | 0.60 | 66.67% |
| 50% | 0.50 | 100.00% |
| 60% | 0.40 | 150.00% |
Typical markup ranges by industry (illustrative starting points, not rules)
| Sector | Common markup range | Notes |
|---|---|---|
| Grocery and staples | 5% to 25% | High volume, thin margins |
| General retail | 50% to 100% | Keystone pricing doubles cost |
| Apparel and fashion | 100% to 300% | Covers returns and markdowns |
| Restaurants (food) | 200% to 300% | Labour and waste are high |
| Jewelry and specialty | 100% to 400% | Perceived value drives price |
Common mistakes to avoid
- Treating markup and margin as the same thing. Markup is profit as a percent of cost, margin is profit as a percent of price. A 50% markup is only a 33.33% margin. If you set a 30% markup believing it earns a 30% margin, you are quietly underpricing every sale.
- Marking up an incomplete cost. If your cost figure leaves out shipping, packaging, payment fees, overhead or an allowance for returns, the real margin is lower than the calculator shows. Build the fullest cost you reasonably can before applying markup.
- Ignoring the market entirely. Cost-plus does not look at competitors or what buyers will pay. A standard markup can leave easy profit unclaimed on a sought-after item, or price you out on a commodity. Always compare the result against real market prices.
- Forgetting that discounts shrink the margin. A price set for a 40% margin does not keep that margin once you run a sale. A 20% discount off the price can wipe out most of the profit, so plan promotions against the margin, not the markup.
- Applying one flat markup to every product. Fast sellers, slow movers, fragile goods and items with high return rates all carry different real costs. A single blanket markup overprices some lines and underprices others. Vary the markup by product where the economics differ.
- Leaving payment and platform fees out of the plan. Card processing, marketplace commissions and listing fees can take 3% to 15% off every sale. If the markup only covers product cost, those fees come straight out of your profit, not the buyer.

Frequently asked questions
How do I calculate selling price from cost and markup?
Multiply the cost by one plus the markup as a decimal: selling price = cost x (1 + markup% / 100). For example, a $40 cost with a 50% markup gives 40 x 1.5 = $60. This cost-plus pricing calculator does it instantly and also shows your profit per unit and margin.
What is the difference between markup and margin?
Markup measures profit against the cost, while margin measures the same profit against the selling price. Since the price is higher than the cost, the margin is always smaller than the markup. A 50% markup equals a 33.33% margin, and a 100% markup equals a 50% margin.
What markup percentage should I use?
It depends on your industry, costs and competition. Retail often runs 50% to 100% markup, while groceries and commodities run much thinner and fashion or jewelry can run far higher. Pick a markup that covers your overhead and target profit, then check the resulting price against what the market will bear.
Is cost-plus pricing a good method?
Cost-plus pricing is simple, transparent and ensures every sale covers cost plus profit, which makes it a solid starting point. Its weakness is that it ignores demand and competitors, so use it as a baseline and adjust toward what customers will actually pay.
Does the unit cost include shipping and overhead?
For an accurate result it should include the direct costs of getting and selling the item, such as materials, inbound shipping and packaging. Fixed overhead like rent is usually covered by the margin rather than baked into unit cost, but the more you capture, the truer the margin.
How do I reach a target profit margin instead of a markup?
To hit a target margin, divide the cost by (1 minus the margin as a decimal). For a 40% margin on a $40 cost, that is 40 / 0.60 = $66.67. The equivalent markup is 66.67%, which is why a margin always needs a larger markup number to achieve it.
How do I convert a markup into a margin?
Divide the markup by one plus the markup: margin = markup / (1 + markup). For a 50% markup that is 0.50 / 1.50 = 33.33%. This markup vs margin conversion is why the calculator always reports both numbers so you never confuse the two.
What is keystone pricing?
Keystone pricing is the retail habit of doubling the cost to set the price. Doubling is a 100% markup, which produces a 50% profit margin. It is a quick default, but on cheap items it can undercharge and on premium items it can leave value on the table.
Can I use a cost-plus pricing calculator for services?
Yes. Add up your direct cost of delivering the work, such as your hourly labour cost plus any materials or subcontractors, then apply a markup that covers overhead and profit. The result is a defensible rate, though for services you should also check it against typical market rates.
Why is my profit lower than the markup suggests?
Usually because the cost you marked up was incomplete or because fees and discounts ate into the price after the sale. Payment processing, marketplace commissions, returns and promotions all reduce the realized margin below the figure the markup implied.
