Inputs and definitions
Count the pieces you will offer, not only the grid you intended to cut. A broken edge or rejected portion still consumed ingredients and labor. Preserve the whole batch cost in the numerator and reduce the sellable denominator instead of making the cost of rejected pieces disappear.
| Input | Unit / meaning | SAMPLE DATA |
|---|---|---|
| Number of trays | trays | 2 |
| Ingredients and pan supplies per tray | USD | 12 |
| Cut pieces per tray | pieces | 16 |
| Unsellable pieces across all trays | pieces | 3 |
| Total labor cost | USD | 24 |
| Total allocated overhead | USD | 8 |
| Packaging per sellable piece | USD | 0.2 |
| Markup | % | 40 |
Formula and worked example
Piece price = ((trays × tray cost + labor + overhead) / (trays × cuts − rejects) + pack) × (1 + markup/100)
SAMPLE DATA — fictional inputs, not US market benchmarks. ((2 × 12 + 24 + 8) / (2 × 16 − 3) + 0.20) × 1.40 ≈ $2.98.
Two fictional trays cost $12 each in ingredients and pan supplies. Add $24 labor and $8 allocated overhead. With 16 cuts per tray and three rejected pieces overall, 29 pieces share $56. Add $0.20 packaging and 40% markup for approximately $2.98 per sellable piece.
Apply the result to this task
If the packaging is a box of several brownies, calculate packaging per piece consistently or prepare a separate box offer. A discount changes the final selling price, not how many trays you actually produced. Check both the unit price and the total order before agreeing to a large-volume offer.
Validation, exclusions and limits
Reject counts must be below the total cut count. Fractional trays and pieces are not a practical production plan. The result excludes unentered delivery, tax, fees and ongoing overhead. It is a sample cost model, not an assertion about US brownie prices or expected profit.
Use finite numbers and keep money precise until the displayed result. Costs and time cannot be negative; required quantities must be positive. Check that your package, recipe and order quantities use compatible units. Clear a field to see the input error rather than carrying an old result into a decision.

A markup multiplies cost by one plus the rate; a target margin divides cost by one minus the rate. They are not interchangeable.
