Set prices with confidence. Calculate selling price from cost and markup, work backwards from a target margin, or see what margin and markup a given price hits.
Adds a percentage of your cost on top to get the selling price. A 100% markup on a $25 cost gives a $50 selling price (50% gross margin).
The shaded area shows the typical 2×–3× cost retail range (50%–67% margin). Your selling price is shown as a dot.
This is a three-mode calculator that turns your unit cost into a defensible selling price — and shows the markup, gross margin, gross profit per unit, and break-even volume behind it. Pick Cost + Markup to add a percentage on top of cost, Cost + Margin to work backwards from a target gross margin, or Price + Cost to reverse-engineer the margin and markup a price you already have in mind actually hits.
The whole point is to stop the markup-versus-margin confusion that quietly erodes profit: a 100% markup is only a 50% margin, and treating them as the same number leaves money on the table. People use it to:

Cost-plus pricing sets the selling price by adding a fixed markup percentage on top of the unit cost. In Cost + Markup mode, a $25 cost with a 100% markup gives a $50 price. It is simple and guarantees a margin, but it ignores demand and competitor pricing, so always sanity-check the result against the market.
Markup is profit divided by cost; margin is profit divided by selling price. The same $5 profit on a $10 cost and $15 price is a 50% markup but only a 33% margin. They are never the same number, which is why this calculator shows both at once.
Margin = markup ÷ (1 + markup). A 100% markup becomes 100 ÷ 200 = 50% margin; a 50% markup becomes 50 ÷ 150 = 33% margin. To go the other way, markup = margin ÷ (1 − margin). The calculator does both conversions automatically.
In Cost + Margin mode it solves backwards using price = cost ÷ (1 − margin). For a 60% target margin on a $25 cost, that is 25 ÷ 0.40 = $62.50. Target margin is capped just under 100% because a 100% margin would require an infinite price.
Break-even units = monthly fixed costs ÷ gross profit per unit. With $2,000 of fixed costs and $25 profit per unit, you need 80 units a month to cover overhead before earning a net profit. If profit per unit is zero or negative, break-even is undefined.
It varies by category: groceries run 20–35%, apparel 50–60%, and software 70–80%. The margin must comfortably cover all operating costs to leave a net profit, so a "good" number depends on your overhead, not just your industry.
It is a classic retail heuristic: 2× cost gives a 50% margin and 3× cost gives a 67% margin. Use the range bar as a starting point, then adjust for competitor pricing, perceived value, and whether the product is premium or low-volume.
