This markup calculator turns a cost price and a markup percentage into a selling price, the cash profit you keep and the profit margin behind it. Type in what an item costs you and the markup you want to add, and it does the arithmetic so you can price with confidence.

It is built for UK sole traders, shop owners, makers, tradespeople and anyone quoting jobs who needs a quick, reliable price without second-guessing the maths or confusing markup with margin.

Quick answer

Markup = (price − cost) ÷ cost × 100. Buying at £60 and selling at £90 is a 50% markup, but only a 33.3% margin, because margin divides by price instead. Quoting markup when a client hears margin is how businesses underprice by accident.

Use the markup calculator above

Enter your cost price (what the item or job costs you) and the markup percentage you want to add. The tool returns the selling price, the profit in pounds and the equivalent profit margin. Change either figure and the numbers update, so you can test a few price points before you commit.

How markup actually works

Markup is the amount you add to your cost, expressed as a percentage of that cost. It answers a simple question: "how much am I charging on top of what I paid?" The formulas are short and worth knowing by heart:

  • Selling price = cost × (1 + markup %)
  • Profit = selling price − cost
  • Markup % = (selling price − cost) ÷ cost × 100

So if a product costs you £40 and you apply a 50% markup, the selling price is £40 × 1.50 = £60. Your profit is £60 − £40 = £20. That £20 is half of your £40 cost, which is exactly where the 50% comes from.

The key thing to hold on to is that markup is measured against cost, not against the price the customer pays. That distinction is what separates markup from margin, and getting it wrong is one of the most common pricing errors in small business. A markup percentage calculator and a profit margin calculator answer related but different questions, so it is worth being clear which one you need.

Markup versus margin: the difference that trips people up

Margin is profit as a percentage of the selling price, while markup is profit as a percentage of the cost. Same pounds of profit, different denominator, different percentage. In the £40 cost / £60 price example, the £20 profit is a 50% markup (20 ÷ 40) but only a 33.3% margin (20 ÷ 60). A 100% markup is a 50% margin. A 200% markup is a 66.7% margin. If you tell a supplier or a customer the wrong number, you can badly misjudge how profitable a price really is.

Worked examples with the maths shown

Example 1: a maker pricing a handmade product

Say you run a candle business. Wax, wick, jar, fragrance and packaging cost you £4.50 per candle. You want a 120% markup to cover your time and overheads. Selling price = £4.50 × (1 + 1.20) = £4.50 × 2.20 = £9.90. Profit per candle = £9.90 − £4.50 = £5.40. As a margin, that is £5.40 ÷ £9.90 = 54.5%. Sell 200 a month and you have made £1,080 gross profit before your other costs.

Example 2: a plumber on a cost-plus job

Cost-plus pricing is markup applied to a job's materials and bought-in costs. Suppose parts and a hired tool cost you £180 for a job. You add a 35% markup on materials to cover handling, waste and a small buffer: £180 × 1.35 = £243. Your labour is charged separately. The £63 added to materials is the cost-plus element a simple cost plus calculator would give you. Work out the labour part with an hourly rate calculator and add it on top to reach the full quote.

Example 3: a retailer reverse-engineering a price

Sometimes you start from the price you want on the shelf and need to check the markup. A homeware item costs you £7.20 and you plan to sell it for £14.99. Markup % = (£14.99 − £7.20) ÷ £7.20 × 100 = 108.2%. Margin = (£14.99 − £7.20) ÷ £14.99 = 51.9%. Both numbers describe the same £7.79 of profit, just measured differently.

Choosing a markup that actually leaves you with profit

A markup is not free money. It has to absorb everything between buying stock and banking the proceeds: payment processing fees, packaging, returns, shrinkage, delivery, marketing and your own time. A 20% markup can look healthy on paper and still leave you out of pocket once a 1.5% card fee, free postage and the odd refund are taken out.

Work backwards from the profit you need. If you know your monthly fixed costs, a break-even calculator tells you how many units you must sell at a given markup before you start making money. Pair that with a clear view of your wider numbers using a profit and loss calculator so the markup you set on each item adds up to a business that pays you.

Remember VAT sits on top of your price

If you are VAT-registered, VAT is charged on your selling price and is not part of your markup or your profit. The standard UK VAT rate is 20%, with a reduced 5% rate and a 0% rate on certain goods, as set out by gov.uk VAT rates. Set your markup on the net (ex-VAT) cost and price, then add VAT afterwards. Our VAT calculator handles the add-on so you do not accidentally treat the VAT as margin. Mixing the two up is a fast way to overstate how well a product is doing.

Keep an eye on the tax that follows the profit

Markup creates gross profit, and profit is what you are eventually taxed on. A sole trader pays Income Tax and Class 4 National Insurance on taxable profits, while a limited company pays Corporation Tax. None of that changes how you calculate a markup, but it is a reason not to price so thin that there is nothing left after costs and tax. For broader business and money planning, the MoneyHelper service from the government is a useful free resource, and gov.uk's guide to setting up a business covers record-keeping you will need anyway.

Common mistakes when applying markup

  • Calling a markup a margin. A 50% markup is only a 33.3% margin. If you assume they are the same, you will consistently overestimate your profitability.
  • Marking up the VAT-inclusive cost. Always work from the net cost and add VAT at the end, or your figures drift.
  • Forgetting variable selling costs. Card fees, postage and returns eat into the markup. Build them into the cost before you apply the percentage.
  • Using one markup for everything. Fast-moving, low-value items often need a higher markup than premium pieces. Set the percentage per product, not across the board.
  • Discounting without recalculating. Knock 20% off a price and your profit can halve. Check the after-discount markup with a discount calculator before you run a sale.
  • Ignoring rounding. Pricing to £9.99 instead of £9.90 is fine, but round on the final price, not mid-calculation, so the maths stays honest.

These figures are estimates for guidance only and not personal tax or financial advice. For decisions with significant tax consequences, check the position with HMRC or a qualified accountant.

Who should use this calculator

This is for setting a selling price, and it exists because markup and margin are constantly confused — including by people running businesses. They are not the same number. Markup is profit as a percentage of cost; margin is profit as a percentage of the selling price. A 50% markup gives you a 33% margin, and pricing as though they were interchangeable is how businesses quietly undercharge.

If you already have a price and want to know the margin it delivers, the profit margin calculator works from the other direction.

What this calculator assumes

  • Markup is calculated on cost: cost plus the markup percentage of that cost gives the price.
  • The cost you enter is the direct cost of the item — what you paid for the goods.
  • Prices are shown excluding VAT unless you have entered VAT-inclusive figures.

Limitations — what it does not cover

  • Overheads. Markup on direct cost does not pay rent, wages or software — those come out of the gross profit it produces.
  • VAT, which must be added on top for a registered business and is not yours to keep.
  • Payment processing fees, typically 1.5–3%, taken off the price rather than the cost.
  • Discounting and returns, which reduce the realised markup below the intended one.
  • What the market will pay. Cost-plus pricing ignores demand entirely.

Frequently asked questions

What is the difference between markup and margin?
Markup is profit measured against your cost; margin is profit measured against the selling price. The same pounds of profit give different percentages. A product bought for £40 and sold for £60 has a 50% markup (20 ÷ 40) but a 33.3% margin (20 ÷ 60). Markup is usually the larger number.
How do I calculate selling price from cost and markup?
Multiply the cost by one plus the markup as a decimal. Selling price = cost × (1 + markup %). For a £25 cost with a 60% markup, that is £25 × 1.60 = £40. Your profit is £40 − £25 = £15. The markup calculator does this instantly for any figures you enter.
What is cost-plus pricing?
Cost-plus pricing adds a set markup percentage to what an item or job costs you, so the price always covers your costs plus a margin. It is common for tradespeople and manufacturers. A cost plus calculator takes your material or unit cost, applies the markup, and shows the price and profit.
Is a 100% markup the same as a 100% margin?
No. A 100% markup means you double your cost, which gives a 50% margin, not a 100% margin. A margin can never reach 100% because that would mean zero cost. Whenever you see a markup figure, expect the margin to be a smaller percentage on the same sale.
How do I work out the markup percentage from a price?
Subtract the cost from the selling price, divide by the cost, then multiply by 100. Markup % = (selling price − cost) ÷ cost × 100. If something costs £8 and sells for £12, the markup is (12 − 8) ÷ 8 × 100 = 50%. A markup percentage calculator reverses the maths for you.
Does markup include VAT?
No. If you are VAT-registered, set your markup on the net (ex-VAT) cost and price, then add VAT on top of the selling price afterwards. VAT is collected for HMRC and is not your profit, so including it in the markup would overstate how profitable the product really is.
What is a good markup percentage for a small business?
There is no single right answer; it depends on your costs, sector and competition. Retail markups often range widely, while service work may use lower material markups plus separate labour. The key is that the markup covers all your selling costs and still leaves a profit after tax once everything is paid.
Why does my profit drop so much when I discount?
Discounts come straight off your profit, not your cost. If your margin is 30% and you cut the price by 15%, you wipe out half your profit on that sale. Always recalculate the markup after a discount so a promotion does not quietly turn a profitable item into a loss.
