Methodology & Accuracy
How this calculator is checked
CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.
Formula used
Food grams = guests x (220 g protein + 120 g salad + 100 g sides + 80 g bread) x meal-format multiplier. Drinks = guests x event hours x 1.1.
Standard or basis
Basis: transparent planning arithmetic using the visible inputs and assumptions on this page.
Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.
