Portion maths without guesswork
The calculation is people × servings per person ÷ recipe servings. Six servings feeding nine people at one serving each needs a 1.5× batch. The tool also shows how many servings you would actually make if you round up to whole batches, and what is left over.
What counts as a serving
Recipe servings are optimistic. A cake recipe claiming 12 servings usually feeds 8 at a party; a chilli claiming 4 feeds 3 hungry adults. When feeding a group, set servings per person to 1.2–1.5 for a buffer rather than cooking exactly to the number.
Sides, mains and appetites
- Buffet: assume 1.2 servings per person — people take a bit of everything
- Kids: count them as 0.6 of an adult portion
- Heavy sides: reduce the main by 20%
- Dessert: 0.7 per person is usually enough after a big meal
Round up to whole batches
It is easier to cook 1.5× than 1.35× — measuring gets error-prone and the leftovers are usually welcome. The tool shows the leftover servings so you can decide consciously.
Frequently Asked Questions
How many servings per person should I plan?
1 for a plated dinner, 1.2–1.5 for a buffet, 0.7 for dessert after a large meal.
Does the calculator round up?
It shows both the exact multiplier and the leftover if you round up to a whole batch.
Can I use it for a party of 50?
Yes, though for large events cook in batches sized to your equipment rather than one giant batch.
