How it is calculated
Profit before the change = (price − variable cost) × volume − fixed costs. Profit after the change uses the same formula with a new price = current price × (1 + price change ÷ 100). Sales volume is assumed unchanged in this calculation.
Because fixed costs don't change and the entire margin from each unit sold flows straight into profit, even a small price change usually produces a disproportionately large profit change — especially if the margin (price minus variable cost) is small relative to the price itself.
This calculation doesn't account for the fact that a price change almost always shifts sales volume too (demand elasticity) — it estimates an 'all else equal' effect, i.e. the boundary impact of price alone. To assess profit when both price and volume change, use the separate calculators or work through it step by step.
