The cost of living in Bangkok is more than the north.
Like Northern Thailand, the cost of living in Bangkok is cheap especially if you are using Airbnb coupons to pay the rent. Each of these has its own unique pace of life, uniqueness, and vibe.
Bangkok is vibrant, hectic and fun. If you are backpacking Thailand alone make sure to brush up on your Bangkok solo travel tips.. The city is a significant party hotspot for tourists flying a world away to revel in nonstop nightlife. Shopping in Bangkok is awesome!
Bangkok is made for people wanting to party every night of the week, but there is more to Bangkok than the energetic social scene. It is also a fantastic place to live for travelers who want to enjoy big city life without paying big city prices as in New York.
If you are staying in an area for a few months, then your best bet for accommodations is to rent an apartment or house rather than staying in a hostel. Hostels in the Bangkok and the southern region average between $5-$15 a night, which adds up to quite a lot over time. While sharing an apartment will be less on average, and you get your own space.

Food is also more expensive in the south because of the flocks of tourists that head there to enjoy the gorgeous beaches and tranquil islands.
The key is to settle in and find the small local restaurants, so that food costs are not high. Plus, the food usually is better.
For an average cost of living in the South of Thailand or Bangkok, you should budget $1,000 -$1,200 a month. This will take care of all your expenses as well as give you plenty of money to enjoy life, see the sights, and go scuba diving in some of the most beautiful places in the world. ( Even if you are diving in a tropical storm)
However, keep in mind that a $1,000 a month will let you live comfortably in southern Thailand and Bangkok, while a that amount in in the North will let you live like a king.
