What This Calculator Does
The Price from Net Profit Margin Calculator works backward from a profit goal to the price you should charge. Instead of guessing a markup, you tell it your costs and the net profit margin you want to keep, and it returns the exact selling price that delivers that margin. This is essential for product pricing, service quoting, and break-even planning.
The Formula Explained
Net profit margin is profit as a percentage of revenue, not cost. Because the profit is measured against the price itself, you cannot simply add the margin to cost — you must divide:
Here Cost is your variable cost per unit, Fixed per Unit is any fixed overhead allocated to each unit, and Net Margin% is expressed as a decimal (e.g. 30% = 0.30). Dividing by (1 - margin) ensures the desired percentage of the final price is left over as profit.
How to Use It
Enter your variable cost per unit, your fixed cost allocated per unit, and your target net profit margin as a percentage. The calculator shows the required selling price, total cost, profit per unit, and the equivalent markup on cost.
Worked Example
Suppose a product has a 20 variable cost and5 of fixed cost per unit, and you want a 30% net margin. Total cost = $25.
Of that price, exactly 30% ($10.71) is profit.
