Methodology

Bake Pricing uses decimal arithmetic for money, normalizes compatible units, validates impossible inputs, and labels results as estimates.
Target price
Cost ÷ (1 − target margin). Margin must be below 100%.
Break-even
Fixed costs ÷ (selling price − variable cost), rounded up.
Limits
Tax, density, waste, capacity, and local regulations require facts outside a generic calculator.
