Formulas and assumptions
- Gross profit = selling price - cost; margin = gross profit / selling price; markup = gross profit / cost.
- A zero selling price has no defined margin; a zero cost has no defined markup. These display as Not available, not 0%.
- Negative profit and rates are possible. This is a per-unit comparison, not an accounting net-profit calculation.
