Free group travel tool
Estimate what your group trip will actually cost per person.
Separate fixed shared costs from individual spending, model a realistic per-person total, and see what happens to the budget if the committed headcount changes.
This is a planning model, not a live booking quote. Enter your own numbers or use an explicitly labeled destination example as a starting point.

Interactive budget
Build the trip from the costs that actually move.
All values are editable planning assumptions in USD. Claira is not quoting live airfare, lodging, tickets, inventory, or availability here.
Use the people you would actually book around, not the invite list.
Food is modeled across nights + 1 travel days.
Use an average only if the group's origins are reasonably similar.
Total stay cost for the whole group, including known taxes and fees.
Airport transfers, taxis, vans, rental cars, parking, or drivers shared by the group.
A planning allowance for meals and routine drinks, separate from nightlife.
Per-person tickets, beach clubs, tours, or activities that are not shared bookings.
For a boat, private table, group tour, or other fixed-cost shared booking.
Tickets and planned individual nightlife spend.
Groceries, tips, supplies, small fees, decorations, or contingency shared by the group.
Method
Shared costs should be modeled at the committed headcount.
Lodging, private transport, boats, and other fixed bookings do not become cheaper just because someone drops out. Claira divides those costs across the committed travelers, then adds per-person categories such as airfare, food, tickets, and nightlife.
Why a range?
One exact number creates false confidence.
Travel prices and discretionary spending move. The low/base/high sensitivity range shows how exposed the group is without pretending Claira can forecast a future fare, hotel rate, table minimum, or activity price from static assumptions.
Use the calculator before the group starts paying deposits.
Confirm the real group
Build around committed travelers so the lodging and shared-booking math is not dependent on people who may never come.
Separate core from optional
Keep required shared costs distinct from nightlife, upgrades, and activities that not everyone has to buy.
Stress-test dropouts
See how one person leaving the trip changes the fixed cost burden for everyone who remains.
Claira research
One dropout can materially change everyone else's fixed-cost share.
Claira stress-tested the same fixed-cost rule across 18 standardized celebration, ski, and Formula 1 trip scenarios with groups of six to ten travelers. The exercise quantifies why organizers should model the committed headcount and then run a one-person-down stress case before making large shared bookings.
- 18
- standardized modeled trips included in the dropout stress test
- $151
- median modeled one-person dropout tax per remaining traveler
- $47–$297
- modeled range of added cost per remaining traveler after one dropout
This is a modeled stress test, not cancellation-rate data, observed traveler spending, or a live-price study. Actual exposure depends on your fixed bookings, refunds, replacement-traveler options, and committed headcount.
Destination examples
Start with an editable destination model.
These versions load illustrative assumptions so the cost categories are easier to understand. They are not live market averages or quotes; replace the example with the group's actual flight, stay, and activity options.
