What Travel Budget Planner does, with a checked example
Enter what each part of the trip will cost - flights, hotels, food, activities, transportation - and mark each item as happening once or every day. The tool multiplies daily items by the trip length, totals each category, and lays the spending out day by day, so you get both a grand total and a sense of what each day costs. The thing people get wrong: it does not know what anything actually costs. It is arithmetic, not a price database. A figure like "hotel, $140 per night" is a guess you supply, and the total is only as good as that guess.
Worked example
A concrete input and expected output from the current implementation.
Input
7-day trip. Flight: $320 once. Hotel: $120 per night. Food: $45 per day. Activities: $30 per day. Local transport: $18 per day. Airport taxi: $35 once.
->
Expected output
Grand total: $1,846. By category: flights $320, hotel $840, food $315, activities $210, transportation $161 (local transport $126 plus taxi $35). Per-day recurring costs: $213 (hotel $120 + food $45 + activities $30 + local transport $18). One-time costs: $355 (flight $320 + taxi $35). About $264 per day on average.
Each per-day item is multiplied by the 7-day trip: hotel $120 x 7 = $840, food $45 x 7 = $315, and so on, while the flight and taxi are added once. The category subtotals, the per-day recurring figure, and the one-time figure all reconcile to $1,846, so the only inputs that move the total are the amounts, the frequencies, and the day count.
