What It Means
A family vacation is a trip that parents and children take together, from a weekend at a lake to a week abroad. Its budgetBudgetA plan for a set period, usually a month, that lists the money you expect to receive and how you'll spend or save it. See more has two kinds of cost: shared costsShared expensesCosts two or more people agree to split, such as rent, utilities, groceries or a shared subscription, as opposed to costs each person covers alone. See more, such as a rental, a hotel room or gas, which stay about the same whoever comes, and per-person costs, such as plane tickets, admission and meals, which grow with every family member. Children also bring their own paperwork and safety steps, like passports and car seats.

Shared costs stay the same however many people come; per-person costs multiply. Change the number of people and watch the cost per person. Starting numbers are examples.
How People Say It
- "Are we doing a family vacation this summer or saving for next year?"
- "Grandma's coming, so the rental just got cheaper per person."
- "Kids eat free at breakfast, that helps."
The Breakdown
Worked example. A family of four, four days at a lake rental (all example amounts):
| Cost | Type | Math | Amount |
|---|---|---|---|
| Rental | Shared | $900 | |
| Car, gas and parking | Shared | $200 | |
| Tickets and admission | Per person | $60 × 4 | $240 |
| Food | Per person | $35 × 4 days × 4 people | $560 |
| Total | $1,900 |
That's $475 a person. If a grandparent joins, the total rises by one person's $200 to $2,100, but the cost per person falls to $420, because the $1,100 of shared costs is split five ways.
What the result means. When shared costs make up most of the total, adding people (or traveling with another family) lowers the cost each. When per-person costs dominate, as with flights, each extra traveler adds close to the full amount.

FAQ
How much does a family vacation cost?
It depends on where you go, how you get there and how many people come. Add the shared costs (lodging, car) to the per-person costs (tickets, food) times the number of people; the calculator above does it with your numbers.
How can a family vacation cost less per person?
Lean on shared costs, which don't grow with each traveler, such as a rental instead of several hotel rooms or a drive instead of flights. Fee-free days at national parks also cut entrance costs for U.S. citizens and residents.
What paperwork do kids need for a trip abroad?
A U.S. passport. Children under 16 apply in person on Form DS-11 with both parents' consent, and it's valid for 5 years, per the State Department. A passport card covers land and sea travel to Canada, Mexico, Bermuda and the Caribbean, but not international flights.
