What it does
Find the sales volume where you stop losing money, and see how much room you have before you do. Then test what a price change or cost change does to profit. You give prices, variable costs and fixed costs. The skill works out the profit per unit, the breakeven in units and in revenue, the volume needed for a target profit, and your margin of safety. It checks whether costs are split fairly, since items like overtime hide variable costs inside fixed ones. It also handles step costs, product mixes and one-off orders, where the answer depends on spare capacity. Use real history if you have it.
