How It Works

How to Plan a Travel Budget

Break travel costs into categories: transportation, lodging, food, activities, and local transit.

Formula

Total = Flights + (Hotel x Nights) + (Food + Activities + Transport) x Days

Worked Example

6-day, 5-night trip: $400 flight, $150/night hotel, $60 food, $40 activities, $20 transport per day.

flight_cost = 400hotel_per_night = 150nights = 5daily_food = 60daily_activities = 40daily_transport = 20trip_days = 6
  1. 01Flights = $400
  2. 02Lodging = 5 x $150 = $750
  3. 03Daily expenses = (60 + 40 + 20) x 6 = $720
  4. 04Total budget = $400 + $750 + $720 = $1,870
  5. 05Per day average = $1,870 / 6 = $312/day
