The idea in briefAdd smaller on-trip costs after the big bookings.

Booking the big items can bring relief, but small payments during a trip can push the total away from expectations. This calculator organizes the numbers you enter; it does not predict current prices.

01

Decide whose budget you are counting

At a glancePut every input on the same whole-group basis.

State whether the figures cover one person or the whole group. Mixing shared costs such as rooms with individual fares can distort the total. The calculator below expects whole-group totals in the edition's displayed currency.

02

List the easy-to-miss items

At a glanceInclude transport, meals, activities, connectivity and a reserve.

Include airport and hotel transfers in local transport. Estimate meals by number per day and days, and use final booking totals for activities, admission and connectivity. Choose a reserve yourself for unexpected transport or changes.

03

Separate confirmed and estimated costs

At a glanceReview the budget once before departure and again after returning.

Keep paid amounts apart from estimates for unbooked items. Exchange rates and card charges can change the final bill. Replace estimates with actual spending after the trip to improve the next plan.

04

A fictional example of shared and individual costs

At a glanceMultiply personal fares by travelers, but use the booked room total once.

These are practice numbers, not market prices. Two travelers each paying KRW 300,000 for flights and sharing a KRW 400,000 room total should record KRW 600,000 in flights and KRW 400,000 in accommodation. Multiplying the room total by two again would double-count it. For personal settlement, agree how to split the group total. Keep this KRW example separate from the calculator's currency; no exchange conversion is performed.

05

What to change when you are over budget

At a glanceRevise costs you can actually change, including the cost of changing them.

First separate changeable spending from confirmed commitments. Lowering the recorded price of an already-booked flight only changes the spreadsheet, not reality. Adjust undecided activities, meals or transport, and include any change fees.

A useful term · Reserve

At a glanceA reserve covers unexpected costs, not omitted planned spending.

Money set aside for unexpected spending rather than a predetermined purchase. Do not omit known meals or transport and assume the reserve covers them.

Make the budget useful for the next trip too

Take this with youAfter the trip, note why important spending differences occurred.

Before leaving, a budget helps you choose. After returning, it becomes evidence for the next plan. Add a short reason beside one or two differences between forecast and actual spending. Then you can allocate money where it is needed rather than raising the budget blindly.
