Margin vs markup — they're not the same
This trips up a lot of new sellers. Markup is how much you add on top of your cost; margin is your profit as a share of the final price. A 100% markup on a £6 item gives a £12 price — but that's only a 50% margin, not 100%. If you price to a markup when you meant a margin, you'll quietly undercharge. This calculator lets you work either way and shows you both, so there's no confusion.
Don't forget your time
If you make the product yourself, your labour is a real cost — leaving it out is the fastest way to a business that feels busy but never pays you. Put in the minutes per unit and an honest hourly rate, and the price reflects the work, not just the materials.
Covering the overheads
Materials and labour are the direct costs; rent, tools and subscriptions are the overheads you pay whether you sell one or a hundred. Pop your monthly fixed costs and rough sales volume into the advanced section and the calculator spreads them across each unit and tells you how many you need to sell to break even.

Common questions
What margin should I aim for?
It varies by trade — physical products often target 50–70% gross margin to leave room for marketplace fees, discounts and returns; handmade and premium goods go higher. Whatever you pick, make sure the price covers your true cost (including your time) with margin to spare.
Does this include selling-platform fees?
Not directly — this prices the product itself. If you sell on Amazon, eBay or Etsy, use those reverse fee calculators (in our free tools) to work out what to list at so you still keep this margin after their cut.
What's the Premium CSV for?
It downloads the full costing breakdown as a spreadsheet you can keep, share or use across a range of products. It's one of the Premium features available when you log in.
