What is Trip Budget Calculator?

The trip budget calculator sums daily costs across categories plus one-time costs (flights), with a percentage buffer for unexpected expenses.

Formula

Subtotal = (daily costs sum) × days + flights. Total = subtotal × (1 + buffer%/100).

Worked example

7 days, $150 lodging + $80 food + $30 transport + $50 activities = $310/day × 7 = $2170. Plus $600 flights = $2770. With 15% buffer = $3186.

How to use this calculator

  1. Enter trip length and per-day costs by category.
  2. Add total flights/transit cost.
  3. Pick a buffer percentage (10–20% typical).

Frequently asked questions

What buffer percentage should I use?

15% is a good default. 25% for less-developed destinations or trips with a lot of activity options. 10% for tightly-planned trips with prepaid lodging and tours.

What's a typical food budget abroad?

U.S. cities: $60–100/day for comfortable eating. Western Europe: €60–90/day. SE Asia: $20–40/day. Japan: ¥7,000–10,000/day. Adjust based on your eating style.

Should taxis be in transport or activities?

Daily transit (airport, intercity, local taxis) → transport. Specific tour transport (bus tour, day trip transport) → activities.

What about souvenirs?

Add a separate "miscellaneous" line or include in your buffer. Easy to forget but easily $100+ over a 1-week trip.
