Start with people, nights and the route
Budget by trip first, then divide by travellers and days. Count paid rooms by night and meals by person. For a seven-day trip arriving on Day 1 and departing on Day 7, this worksheet assumes six hotel nights. A late departure, early arrival or overnight train can change that count.
Use this formula: rooms × nights × nightly price + people × days × meals allowance + local journeys + intercity journeys + chosen activities + contingency. Add international flights and other excluded items separately. Ask whether each quote is per room, per person, per seat or per vehicle.
The examples below are arithmetic exercises in Thai baht (THB), created by bloggsandco. Room and meal inputs are deliberately hypothetical. They are not observed market averages, advertised hotel deals or a claim that every traveller can book at these prices.
Worked example: solo versus two sharing
| Option | Practical comparison |
|---|---|
| Accommodation | Solo: 6 nights × THB 1,200 = THB 7,200. Two sharing one room at the same assumed rate: THB 7,200 for the room, or THB 3,600 each. Confirm that the quoted rate actually covers two guests. |
| Meals | THB 500 per person × 7 days = THB 3,500 each. For two people the total is THB 7,000. Breakfast included in a room quote should be reflected in the meal allowance. |
| Local transport | Assume THB 1,400 for one person, or THB 2,000 for the two-person party. These are placeholders for a journey list; the shared example assumes some per-vehicle trips. |
| Intercity transport | Assume THB 1,500 per person: THB 1,500 solo or THB 3,000 for two. Replace it with the actual route, date, bags and booking conditions. |
| Activities | Assume THB 1,000 per person: THB 1,000 solo or THB 2,000 for two. List the activities and current admission quotes rather than counting every saved place as paid. |
| Subtotal | Solo: THB 14,600. Two people: THB 21,200 for the party, or THB 10,600 each. |
| Illustrative 10% contingency | Solo: THB 1,460. Two people: THB 2,120. This is an example reserve, not a guarantee that it covers every disruption. |
| Example total | Solo: THB 16,060. Two people: THB 23,320 for the party, or THB 11,660 each. International flights and the exclusions below are additional. |
The shared-room saving comes mainly from dividing one room bill. Do not divide meals, rail seats or admissions by two. If you each need a separate room, the accommodation line doubles instead.
Checked fare examples to replace an allowance
These dated examples help build a real journey list. They are not all journeys one traveller would take, so do not add them automatically to the worksheet.
- BKK–Hua Hin coach: THB 361 per seat on the Roong Reuang Coach route page. Two seats are THB 722 one way, before the separate hotel transfer.
- SRT Red Line airport journey: the operator’s fare table lists THB 33 per adult for Don Mueang–Krung Thep Aphiwat. Two adult seats are THB 66 one way, before any onward MRT fare or hotel transfer.
- Chao Phraya Express Boat: the operator’s service page lists Orange Flag at THB 19 and Yellow Flag at THB 24. Match the flag, stops and operating day to the trip; do not treat these as tourist-boat fares.
Fare examples checked 22 October 2026. Recheck before paying. Use the city transport guide to identify the network and transfer legs. Keep a fare per passenger distinct from a taxi quote for the whole vehicle.
Compare choices over the whole stay
Central hotel versus cheaper room farther out
Example: saving THB 300 a night over six nights saves THB 1,800 per room. If the alternative adds THB 400 in vehicle trips each day for six days, that adds THB 2,400. Under those assumptions the room is cheaper but the trip costs THB 600 more. Replace both inputs with quotes for your own locations.
Flight versus overnight train
Compare the full flight price, baggage and airport transfers against the available train berth and station transfers. Subtract only a room night you really replace. If you need a room for early check-in or the train schedule leaves a gap, include it.
Town hotel versus coastal resort
A breakfast deal or resort meal package can change the comparison, but only if you will use it. Price the evenings you expect to spend in town, the hotel shuttle limits and the arrival transfer. Our mainland coast comparison explains the location tradeoffs.
Keep these costs visible and separate
- International flights and any domestic return connection not listed in your route.
- Insurance, entry-related costs and any requirements that apply to your own circumstances.
- SIM/eSIM, laundry, shopping, drinks, tips and payment or currency-conversion charges where applicable.
- Baggage, extra beds, child seats, hotel deposits and any taxes not included in the initial quote.
- Medical or disruption costs beyond the contingency you selected.
Keep the working sheet in THB. If you want a home-currency total, record the conversion rate and date rather than treating today’s conversion as the final card charge. Avoid counting a refundable deposit as both permanent spending and an available cash balance.
Build an activity allowance from named admissions
Start with the places you really intend to enter. Wat Pho’s operator lists THB 300; TAT’s Wat Arun reference is THB 200. For two foreign adults, the two visits therefore produce a THB 1,000 admission subtotal. If you also choose the Grand Palace, its THB 500 foreign ticket adds THB 1,000 for the pair and includes Wat Phra Kaew inside the complex. Do not add another separate temple ticket for that same inclusion. Our place pages link the sources and flag conflicting hours.
This simple list changes the worksheet. The example’s THB 1,000 activity allowance per person is fully used by those three Bangkok admissions alone. A Doi Suthep outing, a museum or a paid guided activity would need another line. Conversely, an afternoon walking a neighbourhood does not need an invented attraction ticket. Keep transport to the attraction in the transport column, so you can see what you save by dropping an optional visit.
Write each line as quantity multiplied by the correct visitor category. Children’s concessions may use height rather than age, and Thai and foreign tariffs can differ. A published adult reference is not proof that every member of the party pays the same. Note the source date and confirm the gate tariff or operator booking before payment. Leave optional services such as cable cars and guides visible rather than hiding them inside a vague daily sightseeing figure.
Convert a restaurant menu into a meal allowance
Use a menu from the branch you will actually visit. For a concrete Chiang Mai example, Chom’s 2026 Chiang Mai menu lists shrimp Pad Thai at THB 170 before 7% VAT. Two orders are THB 340 before VAT and THB 363.80 after it, before drinks or additional dishes. This is one researched menu example, not a Thailand-wide meal average or a price promised for your travel dates.
Compare that with Chow Mong in Hua Hin, whose published hotel menu lists shrimp Pad Thai at THB 390 with government tax and service already included. Two orders are THB 780 before extra items. The two bills illustrate why a single daily food number needs your actual restaurant choices behind it. They are different venues and experiences, so the arithmetic does not establish which meal offers better value.
For your worksheet, list breakfast, lunch, dinner and drinks separately for one ordinary day. Remove breakfast only when the room deal includes it for every guest. If you plan a shared seafood dinner, list shared dishes once and divide the complete party bill at the end. Confirm allergy requirements directly; a menu title does not establish ingredients or cross-contact arrangements. Keep a modest arrival-day meal in the plan as well as any special dinner you are looking forward to.
What happens when the assumptions change?
Add one paid night
At the worksheet’s hypothetical THB 1,200 room rate, a seventh night adds THB 1,200 to the party accommodation bill. It adds THB 1,200 per person for a solo traveller, or THB 600 each for two sharing that same room. Meals and another day’s journeys are additional if the trip itself becomes longer. An early check-in charge belongs on the room line even when it does not add a calendar night.
Replace an allowance with actual journeys
For two people taking the published THB 361 Hua Hin coach in both directions, four passenger seats total THB 1,444. Add transfers at each end. If you obtain a hypothetical THB 3,000 private-vehicle quote one way, compare it against THB 722 for two coach seats plus their actual connecting rides. The difference buys a different journey; decide using the complete party price, luggage needs and departure time.
Keep a booking ledger beside the estimate
Use columns for item, quantity, price unit, included charges, amount paid and balance due. Mark refundable deposits separately from permanent spending. When a hotel or ticket is booked, replace its allowance instead of adding the receipt on top. Recalculate the contingency against your revised spending base and keep the reserve available. A budget becomes reliable through these small corrections as bookings change; the original example total is only a starting calculation, not a target you must force the trip to meet.
A ten-minute budget check before paying
- Write the number of people, room configuration and paid nights at the top.
- Put a date and a source beside every room, ticket and transfer quote.
- Mark each figure “party”, “room”, “vehicle” or “person”.
- Recalculate after changing a base, airport, train night or hotel.
- Check inclusions and cancellation terms, then keep your reserve separate.
How much money do I need for a week?
There is no single honest total without your room, route and party size. Use the worked example as a calculation template, then replace the assumptions. The result becomes useful when it matches bookable choices for your dates.
Can two travellers just double a solo budget?
Meals and seats often scale by person; a shared room and some vehicle transfers may not. Build the party total first and divide only at the end.
Next step: price the seven-day Bangkok and Chiang Mai route or one-base alternative, then use My Trip to keep the shortlist together. Worksheet and arithmetic reviewed 22 October 2026.
How much money do I need for a week in Thailand?
In the worked example above, seven days and six nights total THB 16,060 for one person, including the illustrated 10% contingency. Two people sharing one room total THB 23,320 for the party, or THB 11,660 each. These figures are the result of the stated assumptions, not current market averages or a quote for your trip. International flights and the separate exclusions still need adding.
On a budget backpacking trip, replace the room and transport lines with the actual bed, berth and bus quotes available. For family travel, price the required room configuration and each child’s transport and admission. A luxury travel budget should include the particular property, transfers and experiences you want. Keep per-person costs separate from shared room or vehicle costs; a single daily allowance can hide that difference.
