Travel Budget Planner
Know the number before you book. Add flights, lodging and daily spend across your travelers and nights, then watch the total land over or under your budget — and where to cut if it's over.
Under the hood
The math, fully exposed
Each line item scales by the right driver — headcount, nights, or both:
Flights = flight per person × travelers
Lodging = lodging per night × nights
Daily spend = daily per person × travelers × nights
Total = flights + lodging + daily spend
- Lodging scales with nights, not people: one room holds the group, so headcount drives food and activities, not the hotel bill.
- Daily spend compounds: it multiplies by both travelers and nights — the line that quietly balloons on longer group trips.
- Cutting a night cuts twice: it removes a night of lodging and a day of per-person spend — the fastest way back under budget.

Answers
Frequently asked questions
What should a travel budget include?
The big three are transport (flights or fuel), lodging, and daily spend — food, local transit, activities and incidentals. This planner covers those, which capture the large majority of most trips. Add a buffer for the things budgets miss: airport transfers, baggage fees, tips, travel insurance, and the souvenirs and "while we're here" splurges that always appear.
How much should I budget per day?
It varies enormously by destination. A rough guide: budget travel in inexpensive regions can run $40–70 per person per day, mid-range trips $100–200, and major cities or premium travel $250+. Food and activities are the swing factors. Research your specific destination — daily costs in Tokyo or Zurich look nothing like Lisbon or Bangkok.
Why does lodging count per night but food per person?
Because they scale differently. A hotel room or rental usually costs the same whether one or two people stay in it, so lodging scales with nights, not headcount. Food, activities and local transit are per-person costs that multiply with both travelers and days. Modeling them separately gives a far more accurate total than a single "cost per day" lumped together.
How do I bring the total under budget?
The biggest levers are usually flights (dates, airports, points) and lodging (location, rental vs hotel, fewer nights). Daily spend adds up but moves in smaller increments. If you are over budget, test cutting a night or two first — it removes both lodging and a day of spending at once. This is an educational planning tool, not financial advice.
