Hosting a gathering means making one of the trickiest decisions in cooking: how much to buy. Buy too little and you're rationing slices of meat at the grill while guests politely smile. Buy too much and you're eating raclette leftovers for a week — or worse, throwing food away.

Kitchen calculators take the guesswork out of portion planning. Whether you're firing up the grill for a casual Saturday with six friends, organizing a raclette night for ten, planning drinks for a 30-person birthday, or putting together a cheese board that actually feeds the table, the math is the same problem: scaling portions to people, appetite, and occasion.

These tools cut through the rough estimates ("about 200g per person?") and give you concrete numbers tailored to your specific event. They factor in the variables that actually matter: how many adults vs. kids, whether it's a main meal or a snack, and how long the gathering runs. The result is a shopping list you can trust.

Why Portion Planning Matters

Underbuying ruins the event. Running out of meat halfway through the grill turns a relaxed afternoon into an emergency supermarket run — assuming the store is even open. Underbuying drinks at a party is worse: guests start leaving early.

Overbuying is the quieter problem. The cheese you bought "just in case" goes moldy. The extra wine sits in a cupboard for two years. The unused meat takes up freezer space until you eventually toss it. Beyond the wasted money, food waste at home accounts for a meaningful chunk of household environmental impact — far more than most people realize.

Getting portions right isn't just about saving twenty euros on a single party. Over a year of regular hosting, the difference between rough guessing and precise planning adds up to real money, less stress, and a reputation as the host who actually has enough wine.

Our Kitchen Calculators

Each tool here solves a specific portion-planning problem hosts run into. The Grilling Calculator handles meat quantities for BBQs — adjusted for whether your guests are casual snackers or serious eaters. The Raclette Calculator works out the cheese-to-potatoes-to-sides ratio that keeps everyone fed without leftovers piling up.

For drinks, the Party Drinks Calculator covers beer, wine, soft drinks, and ice — calibrated to event length and crowd type. And the Cheeseboard Calculator builds a balanced board with the right variety and amount of cheese for your group size.

Pick the tool that matches your event, plug in the numbers, and walk into the supermarket with a list instead of a guess. Browse all the calculators below to find the right one for your gathering.

Common Questions About Kitchen Planning

Do I really need a calculator for a small dinner? For four people, probably not — you cook this often enough to know. But the second you cross into "I've never hosted this many before" territory, intuition fails fast. Eight people aren't twice four; appetites, drink rates, and side dishes all scale differently.

How precise do I need to be? Precise enough that you don't run out, with a small buffer for big eaters. Calculators give you the realistic baseline. Add 5–10% if your crowd skews toward bigger appetites, or if you'd rather have leftovers than risk shortage.
