%
Must be less than 100%.
Engineering Assumptions
- Margin is measured on the selling price, not on cost.
- All percentages and inputs are user-defined; the calculation is purely arithmetic and assumes no particular code or specification.
Formula Summary
- Selling price = cost ÷ (1 − margin%)
- Gross profit = selling price − cost
- Markup% = gross profit ÷ cost × 100

Engineering Insight
As the target margin rises, the selling price rises non-linearly; a 50% margin means doubling the cost. A 100% margin is mathematically impossible as it implies zero cost.
Recommended Action
Compare the required selling price with market levels and client affordability before adopting the target margin.
