Simple markup math: takes a cost and a markup percentage, returns the selling price. The "implied margin" line shows the corresponding profit margin — a useful sanity check, because most people confuse markup and margin.
The formula: selling price = cost × (1 + markup %)
Use markup when setting prices from a cost basis ("I'll mark this up 100%"). Use the Selling Price Calculator (which targets margin) when you want to hit a specific profit margin after all costs including ads.
Markup doesn't include ad cost or payment fees — it's a pure cost-plus calculation. For dropshipping, where ad costs are a major expense, the Selling Price Calculator is usually more useful.
| Input | Value |
|---|---|
| Cost | $20.00 |
| Markup | 100% |
| Selling price | $40.00 |
| Profit per unit | $20.00 |
| Implied margin | 50.00% |
Note: 100% markup = 50% margin. If you said "we have 100% margins" based on this, you'd be wrong by a factor of 2×. Always use margin when reporting financial performance.
Find the selling price that hits a target margin after product cost, shipping, transaction fees, and ad spend per unit.
See the difference between markup % and margin % for the same product. The two are not interchangeable and mixing them up loses money.
Calculate sale price after a discount, and the effective margin you keep. Stop giving away profit without realizing it.
A 50% markup is not a 50% margin. This article shows why mixing them up costs you money, with a real product example.
