Cost of Living in Thailand — How to Build a Realistic Monthly Budget for Bangkok, Chiang Mai and the Islands

Instead of one made-up number, here is how to build your own monthly budget for Thailand: the categories that vary most between people, why Bangkok and Chiang Mai differ, the costs newcomers forget, and the tiers most expats end up in.

Every "cost of living in Thailand" article gives you a single number, and it is always someone else's number. Costs in Thailand vary by a factor of five depending on where you live, what you eat and how much air conditioning you run. This guide shows how to build a budget that is actually yours.

The categories that decide everything

Category Why it varies so much
Rent A studio in a Thai neighbourhood versus a serviced condo in central Bangkok are different worlds
Food Thai food from markets and food courts is cheap; imported groceries and Western restaurants are not
Transport Motorbike or public transport versus taxis and ride-hailing every day
Electricity Air conditioning all day can be the biggest surprise on the bill
Health Insurance premium, or the cost of paying private hospitals directly
Visa and paperwork Extensions, reports, agents, and visa runs add up over a year

Three tiers most people fall into

Rather than quoting figures that will be out of date, price your own tier: check current condo listings in the area you want, look at menus of the places you would eat at, and ask the electricity tariff of the building.

City differences

Bangkok has the widest range at both ends and the best transit. Chiang Mai is cheaper for rent and daily life, with a smaller premium for Western comforts, but you will likely need a scooter or car. Phuket and Koh Samui cost more than Bangkok for many things because goods are shipped in and demand is seasonal. Hua Hin and Pattaya sit in between and suit people who want the sea without island prices.

Costs newcomers forget

Building the budget

Take the six categories, price each one for your tier and city from current listings, add a line for savings and one for "things that go wrong" of about ten percent, and you have a number that is yours. Revisit it after the first two months; electricity and food are the lines that usually move.

Common mistakes

Summary

Pick your tier and city, price the six big categories from live listings, add savings and a buffer, and adjust after two months. That beats any single number, including ours.
