Trip Budget Summary
Daily Variable Travel Allowance Formula
Daily Allowable Spend = (Target Total Budget - Fixed Transit - Fixed Lodging - Pre-booked Tours) / Trip Duration Days- Fixed Costs Subtotal: Sum of prepaid airline tickets, hotel reservations, and advance tour bookings.
- Remaining Variable Budget: Target Total Budget minus Fixed Costs Subtotal.
- Daily Allowable Spend: Discretionary cash available each day for food, transit, tips, and souvenirs.
Step-by-Step Worked Example
Scenario: You have a target vacation fund of $3,500 for an 8-day trip. Your flights cost $900, hotel reservations cost $1,400, and advance museum passes cost $200.
Calculation Steps:
- Fixed Costs: $900 + $1,400 + $200 = $2,500 (71.4% of budget)
- Remaining Variable Budget: $3,500 - $2,500 = $1,000
- Daily Allowable Spend: $1,000 / 8 days = $125.00/day
Result: After covering your fixed reservations, you have $1,000 remaining, allowing exactly $125.00 per day for food, local transport, and entertainment.
