Vacation Food Planner and Grocery Calculator
Calculate trip food by converting adults, teenagers and children into adult-equivalent portions, multiplying by the meal occasions covered by groceries, and then applying portion size, one leftover buffer and equipment limits.
Use the calculator for a vacation rental, road trip, camping stay, hotel, hostel, campervan or group holiday. Grocery-covered meals and restaurant meals stay separate so the same food is not counted twice.

Storage and packing guidance
- A freezer allows batch-cooked portions and frozen ingredients; label quantities and thaw safely.
- Confirm cookware, refrigerator space and basic pantry items with the host before buying duplicates.
How much food do you need for a vacation?
The amount of food depends more on the meals actually covered by groceries than on trip length alone. Seven nights do not automatically mean seven complete self-catering days: arrival, departure, restaurants and day trips change the shop. The planner therefore counts breakfast, lunch, dinner and snacks separately.
How the vacation food calculator works
Adults count as 1.0, teenagers as 1.1, children as 0.6 and toddlers as 0.35. Those adult equivalents are multiplied by the meal occasions covered by groceries. Portion level, trip type and one leftover buffer then adjust quantities. Storage and cooking equipment do not change hunger, but they do change suitable foods and shopping frequency.
Planning groceries by people, days and meals
Plan the whole group first and split the finished shopping list afterwards. Teenagers on active trips may need more than an average adult baseline, while younger children often need less. Use the portion setting for the actual group instead of adding a separate safety margin for every age band.
Vacation rental grocery planning
Confirm refrigerator and freezer space, stove, oven and existing pantry basics. Secure the first meal and first breakfast before arrival; a second shop is often fresher and easier to store on longer stays.
Road-trip food planning
Separate travel-day food from groceries for the accommodation. Keep drinks, snacks and a defined packed meal accessible in the vehicle; perishable food needs a reliable cold chain.
Group holiday meal planning
One combined quantity plan prevents duplicate shopping. Then assign meals, ingredient categories and dietary needs. Plan the reserve centrally rather than asking every shopper to add their own buffer.
Cooking versus eating out
The grocery-covered and restaurant percentages always total 100%. Restaurant meals create no grocery quantity. Additional packed meals and backup meals are added separately and remain visible in the result.
Reducing food waste while travelling
Waste-reduction mode caps the leftover buffer at 5% and recommends smaller shops during longer stays. Use ingredients across several dishes, check supplies already at the accommodation, and reserve the final meal for safely stored leftovers or unopened food.
Worked example: six people for seven days
Example: four adults and two children travel for seven days. They plan seven breakfasts, seven lunches and seven dinners. Breakfast and dinner plus two lunches are grocery-covered; five lunches are eaten outside. That is about a 76% grocery share. The plan also includes one backup meal and a 5% leftover buffer.
Adult equivalents: 5.2. Estimated food weight: 50.7 kg; drinks baseline: 48.2 L.
| Category | Example quantity |
|---|---|
| Bread and bakery | 5.7 kg |
| Rice, pasta and grains | 4.2 kg |
| Vegetables | 10.5 kg |
| Fruit | 7.3 kg |
| Meat or alternatives | 8.9 kg |
Calculation methodology
Adult equivalents = adults + teenagers × 1.1 + children × 0.6 + toddlers × 0.35.
Grocery servings by meal = adult equivalents × planned meal occasions × grocery share × portion factor × trip factor. Light, standard and generous portions use 0.85, 1.0 and 1.15. Camping uses 1.12; road trips 1.03; campervans 1.07; group holidays 1.03. Hotel and hostel settings use 0.9 and 0.95 because fewer complete meals are commonly prepared there.
Leftover allowance = food amount × one selected buffer from 0% to 15%. Waste-reduction mode caps it at 5%. Backup meals are calculated separately at 250 g of shelf-stable food per adult-equivalent meal. Drinks do not receive the leftover multiplier.
Category portions are baselines for a mixed menu. Rice, pasta and potatoes are divided across the starch allowance rather than counted as three complete sides. Replace the category plan with actual recipe yields and adjust for package sizes, climate, activity and individual needs.

Frequently asked questions
How much food do I need for a one-week vacation?
Multiply the travelers by seven days and the meal occasions you will cover with groceries, then adjust for age and portion size. A week with breakfast and dinner cooked needs much less grocery food than a fully self-catered week. The planner separates restaurant meals, packed meals and backup food so they are not counted as full grocery meals twice.
How do I calculate groceries for a group trip?
Convert the group to adult equivalents, count the breakfasts, lunches, dinners and snack occasions, and apply the percentage covered by groceries. Divide responsibility by meal or category only after calculating the combined total, otherwise several people may buy the same buffer.
How much food should I plan for children?
This planner counts a child as 60% and a toddler as 35% of an adult baseline. Teenagers count as 110%. These are planning assumptions rather than nutrition advice, so adjust the portion setting when ages, appetite or activity suggest a different amount.
How much extra food should I bring?
Use a 5% buffer for ordinary variation, 10% when leftovers are intentional, or add clearly defined backup meal occasions for disruption. Do not add a percentage to every category and then add another full emergency reserve, because stacked buffers create unnecessary weight and waste.
How do I plan food for a vacation rental?
Confirm refrigerator space, freezer access, cookware, oven and pantry basics before shopping. Plan the first meal and breakfast before arrival, then schedule another shop if the stay exceeds the safe storage life or capacity of the kitchen.
What food is best when there is no full kitchen?
Choose food that matches the available storage and equipment: whole fruit, bread or gluten-free alternatives, shelf-stable grains, canned beans or fish, ready-to-eat vegetables and suitable dairy alternatives. Without reliable refrigeration, buy perishables in small batches and follow the product's storage instructions.
How can I reduce food waste during a trip?
Use the waste-reduction setting, keep the leftover buffer at 5% or less, plan versatile ingredients across several meals and shop more than once for longer stays. Check what the accommodation already provides and reserve the final meal for safe leftovers or unopened foods.
