Scaling a recipe or production batch up or down for a different quantity means the total ingredient cost scales proportionally too, and working that out for a food business or catering order benefits from a quick, reliable calculation.
Enter your original batch's total cost and size (number of units it produces), and your new target batch size, and this calculator determines the per-unit cost and the total cost for the new batch size, scaled proportionally.
This assumes costs scale linearly with batch size, which holds true for most straightforward ingredient scaling — though very large batches sometimes benefit from bulk ingredient discounts that would make the actual per-unit cost lower than this simple proportional estimate.

Frequently asked questions
Does this account for bulk discounts on larger batches?
No, this calculates a straightforward linear scaling; if buying ingredients in bulk for a larger batch actually costs less per unit, the real total may be somewhat lower than this proportional estimate.
Can I use this for scaling down a recipe too, not just up?
Yes, the same proportional calculation works in either direction — enter a smaller new batch size to see the scaled-down cost.
