How the calculation works
Keep the ingredient unit unchanged during scaling. The factor applies to the ingredient quantity, while the portion size stays the same. Check cooking capacity separately because a larger vessel may change evaporation.
Formula: Current quantity × required portions ÷ current portions.
Worked example
The starting inputs are illustrative assumptions: Current recipe portions: 10; Required portions: 25; Current ingredient quantity (same unit): 400. They produce 1000.00 units. These inputs are editable and are not market prices or industry benchmarks.
Use the result
Scale a recipe on paper, then measure the finished yield. Seasoning, equipment limits and service losses need a practical check.
Keep the period, unit and currency consistent across the inputs. A calculator cannot identify a missing cost from the figures you provide. Retain an invoice or stock-count record for the inputs, and use the result as a check on your operating decision.
