Family Trip Budget Planner
Real per-child cost modeling, not a rule of thumb. Everything runs in your browser — nothing you enter is sent anywhere or saved.
Your Trip
Airlines vary widely; check your specific fare rules. 75% is a reasonable working default, not a quote.
Souvenirs, a missed reservation, a rainy-day backup plan.
Your Estimate
This is a planning estimate from what you entered, not a live price feed. Nothing you type is saved or sent anywhere — it recalculates entirely in your browser.
How to use this well
Pull real numbers from wherever you can: flight search results for your actual dates, a specific hotel or rental's nightly rate, and the cost-per-day figures on our destination guides where we've already researched them. The default values above are reasonable US domestic starting points, not a quote for your trip — the whole point of this tool is replacing them with your own real numbers.
For destination-specific cost research, see our flagship guide or any individual destination guide's "What It Costs Per Child, Per Day" section.
