This selling price calculator works out the price you need to charge to hit your target profit margin, starting from your product’s cost.
Pricing that leaves you a margin
Setting a price “by feel” or by simply multiplying the cost often leaves money on the table. Instead, start from the margin you actually want and work backwards to the price.
The formula
For a cost C and a target margin m (as a fraction of the sale price), the price is P = C ÷ (1 − m). The profit per unit is then P − C. This is different from adding the margin on top of the cost, which is a markup and produces a lower price than intended.
