Scenarios assume each change happens on its own terms — e.g. a price increase doesn’t automatically reduce volume. Use the volume slider to model customer reaction.
Revenue = price × units (or entered directly; then units = revenue ÷ price)
COGS = COGS per unit × units · Gross profit = revenue − COGS
Operating profit = gross profit − variable expenses − fixed expenses
Contribution margin ratio = (revenue − COGS − variable expenses) ÷ revenue
Break-even revenue = fixed expenses ÷ contribution margin ratio
