Example results use the default display profile. The calculator above follows your selected country and units.
How to read the result
- Read the main result first. The supporting figures for portions, and core portions explain how the estimate is built.
- The method is (People × meals + extra portions) × portion weight. Keep the units consistent and use values from the same time period.
Edge cases worth checking
When people is unusual
Every portion uses the same total food weight. Double-check this input before relying on the result.
When extra portions is uncertain
Ingredient-specific cooking loss is excluded. Run a lower and higher value to see a useful range.
What changes the result most
People
Use the count you expect in real life. Round up when a partial people cannot be purchased or used.
Meals per person
Measure meals per person with the same unit shown beside the input. Convert first if your source uses another unit.
Food per portion
Change food per portion on its own first. This shows how strongly it affects the answer.

Common mistakes
Check people
Every portion uses the same total food weight. Make sure this matches the number you enter.
Keep extra portions consistent
Ingredient-specific cooking loss is excluded. Use the same units and time period throughout the calculation.
Do not rely on one meal prep batch size scenario
Run a cautious case and an optimistic case. The range is often more useful than one exact-looking number.
