Thailand Trip Cost Calculator

1. 01Enter travelers and nightsSet how many people are going and how many nights you will stay. Accommodation is charged per night; food, transport, and activities are per traveler per day.
2. 02Add your nightly and daily costsFill in accommodation per night for the whole party, and food, local transport, and activities per traveler per day, using prices you researched.
3. 03Add one-time costsEnter intercity travel and transfers (such as domestic flights, overnight trains, or a ferry to the islands) and a shopping and misc allowance, both per traveler.
4. 04Set a bufferAdd a contingency percentage for price changes and surprises. Ten to fifteen percent is a common starting point you can adjust.
5. 05Read and copy the estimateSee the total, the cost per traveler, the daily average, and the category breakdown. Copy the summary to compare trips or share with travel companions.

• First trip to ThailandTurn a rough idea into a concrete number before you commit, so you know whether the trip you imagine fits your savings.
• Comparing trip lengthsSee how the total and daily average change between a one-week Bangkok stay and a two-week island-hopping itinerary with the same daily spend.
• Splitting a group tripUse the per-traveler figure to see what each person should budget, then split shared costs fairly with a companion tool.
• Deciding where the money goesThe biggest-category readout shows whether accommodation, food, or intercity travel dominates, so you know where trimming helps most.

• Two travelers, ten nightsWith accommodation at 35 per night, food at 18 per person a day, and modest transport and activities, plus an island-transfer allowance and a buffer, the tool sums each category and shows a total and per-person figure. Replace every number with your own.
• Shorter, faster tripA five-night trip with higher daily activity spend shows how a shorter stay can still carry a high daily average when you pack in tours and diving.
• Solo backpackerOne traveler with low accommodation and food per day, and little shopping, produces a lean total that makes the effect of intercity travel obvious.

• Research a few real prices firstLook up two or three actual hotel and meal prices for your dates and area before you fill in the fields, so the estimate rests on real numbers.
• Keep the currency consistentThe currency is only a label and nothing is converted, so enter every amount in the same currency to keep the total meaningful.
• Treat intercity travel as its own lineDomestic flights and island ferries can be a large share of a Thailand budget, so estimate them separately rather than folding them into local transport.
• Revisit the bufferA larger buffer is sensible for peak season such as the cool, dry months around the new year, when prices and demand rise.

Accommodation is your per-night figure multiplied by the number of nights. Food, local transport, and activities are each multiplied by the number of travelers and the number of nights, because they are entered per traveler per day. Intercity travel and shopping are multiplied by the number of travelers only, since they are one-time costs. Those six category totals are added into a subtotal, the buffer percentage is applied on top, and the result is the total. The per-traveler figure divides the total by the number of travelers, and the daily average divides it by the number of nights.

Inputs are travelers, nights, accommodation per night, food, local transport, and activities per traveler per day, intercity and shopping per traveler, a buffer percentage, and a currency label. Outputs are the total trip estimate, the cost per traveler, the daily average, a per-category breakdown, and the biggest category. The tool assumes your figures are in one currency and that the daily amounts apply to each night of the trip. It does not model flights from home unless you include them in intercity travel.

The same calculator handles a range of styles by changing the inputs. A budget trip uses low accommodation and street-food spend with more local transport; a comfort trip raises accommodation and activities such as tours and diving; a group trip raises travelers so shared nightly costs spread across more people in the per-traveler figure. You can model a same-day or zero-night side trip by leaving nights at zero and using only the one-time categories.

Prices for accommodation, food, and transport in Thailand vary by region, season, and travel style, and they change over time. Building typical figures into the tool would be out of date quickly and would give a false sense of precision. Instead you enter the prices you researched, so the estimate reflects your real trip. There is no currency conversion either, which is why the currency field is only a display label.

The estimate is only as good as the numbers you enter, and it will not warn you if a figure is unrealistic. A common mistake is mixing currencies, or entering a per-person nightly rate in the accommodation field, which is defined as the whole-party cost per night. It also does not include travel insurance, visa fees, or home-country flights unless you add them to a category yourself.

Everything runs in your browser. The amounts you type and the results are not uploaded, not saved to storage, and not sent to analytics beyond a general usage signal. Refreshing the page clears everything, so nothing about your trip is retained.

Does it use real Thailand prices?

No. You enter every amount yourself. There are no built-in prices, which keeps the estimate current and specific to your trip.

Does it convert currencies?

No. The currency selector is only a label and nothing is converted, so enter all amounts in the same currency.

How should I handle island transfers and domestic flights?

Put domestic flights, overnight trains, and island ferries in the intercity and transfers field, which is charged per traveler. Keep tuk-tuks, songthaews, and city rides in local transport.

Is the accommodation figure per person or per room?

It is the cost per night for the whole party, so enter the nightly room or lodging total rather than a per-person rate.

What buffer should I use?

A buffer of ten to fifteen percent is a common starting point. Raise it for peak season or a loosely planned trip, and lower it if your prices are already firm.

Is my data saved?
