The Markup Calculator is an essential tool for UK businesses looking to determine the selling price from a given cost and markup percentage. This tool is particularly useful for retailers, wholesalers, and service providers who need to set competitive prices while ensuring profitability.
How Markup Calculator works in 2026
In 2026, the Markup Calculator functions by taking the cost of a product or service and adding a specified markup percentage to determine the selling price. This calculation is straightforward: Selling Price = Cost + (Cost x Markup Percentage). For example, if a product costs £100 and the markup is 25%, the selling price would be £125.
HMRC considers the markup when calculating VAT. If a business is VAT registered, the selling price should include VAT at the standard rate, which remains at 20% in 2026. Businesses must accurately calculate and report VAT to HMRC, ensuring compliance with tax regulations. Companies House requires businesses to maintain accurate financial records, including details of pricing strategies and markup percentages used.
When to use Markup Calculator
The Markup Calculator is useful in various situations:
- Scenario 1: A retail shop determining the selling price of imported goods
- Scenario 2: A wholesaler setting prices for bulk orders to maintain profit margins
- Scenario 3: A service provider calculating the price of a new service package
- Scenario 4: An online seller adjusting prices in response to supplier cost changes

Worked example
Consider a UK-based sole trader who sells handmade jewellery. The cost to produce a necklace is £40. The trader decides on a markup of 50% to cover overheads and ensure profit. The calculation for the selling price is as follows: Selling Price = £40 + (£40 x 0.50) = £60. If the trader is VAT registered, they must add the VAT: £60 x 1.20 = £72. The final price to customers will be £72, including VAT.
Common mistakes
- Incorrectly calculating markup percentage. Always use the formula: Cost x Markup Percentage.
- Forgetting to add VAT to the selling price. Ensure VAT is included if applicable.
- Failing to update prices with cost changes. Regularly review supplier costs.
- Setting prices too low, reducing profitability. Analyse market trends and competitor prices.
Related calculations
Users often need to calculate VAT separately from markup. Additionally, understanding the difference between markup and profit margin is important. While markup refers to the percentage added to the cost price, profit margin is the percentage of the selling price representing profit.
What HMRC / Companies House checks
HMRC and Companies House require businesses to keep detailed financial records. This includes maintaining copies of invoices, receipts, and calculations of selling prices. Records should be kept for at least six years. Discrepancies in VAT returns or Corporation Tax filings may trigger audits or inspections.
Bottom line
The Markup Calculator is a valuable tool for UK businesses to ensure their pricing strategies are effective and compliant. Accurately calculating the selling price using the correct markup percentage helps maintain profitability and meet tax obligations. Regularly review and adjust prices in line with market and cost changes to stay competitive.
