Work backwards from cost and a target margin to the selling price you need.
Selling price = Cost ÷ (1 − Target margin).
Cost 450 and a 30% target margin. Price = 450 ÷ 0.70 = 642.86.
If you add 30% of cost, you do not get a 30% margin. You get a 23% margin. To land on a margin, divide cost by one minus the target. The selling price calculator exists because that mistake shows up in spreadsheets constantly.
At minimum: product cost. Better: product + inbound freight + packaging. Best for channel pricing: add expected payment fees, marketplace commission and average shipping subsidy. The more complete the cost, the more honest the price.

Use any currency as long as every input uses the same one. The math does not depend on a currency code.
Selling price = Cost ÷ (1 − Target margin).
Calculate gross profit and profit margin from revenue and cost. Use it before you set a selling price or judge a channel.
Convert cost into a selling price using a markup percentage, and see the implied profit margin.
Find how many units you need to sell to cover fixed costs at a given price and variable cost.
Start an online store from offer and unit economics through platform, catalog, payments, shipping and a launch checklist — without treating legal registration as a how-to.
Build product pages that shoppers and search engines can use: media, specs, shipping and returns, related products, and SEO working with conversion — without invented reviews.
Gross, contribution and net margin answer different questions. Channel fees, shipping and returns sit between list price and cash. Worked numbers included.
Markup is the add-on over cost. Margin is profit as a share of selling price. Mixing them up is a common pricing error. Formulas and a conversion table.
D2C, marketplaces, wholesale, subscriptions and dropshipping differ in margin, inventory risk and ops load. Compare the economics before you pick a model.
Before you launch, lock the offer, suppliers, margin, photos, policies and support. A practical checklist for opening a store—not a platform sales pitch.
