Fifty Baht Is Called Two Things and Knowing Which One Saves You Money
Joh, song, sao, and the small silver coins nobody has used in fifteen years. The price system is not complicated, it is just not English.
Stallholder says a hundred and sixty. I hand over two hundred. She gives me a coconut milk pancake for free and I consider the transaction a success.
Later, at a market five streets away, the same item is eighty. Which means I paid double, which means the round numbers were a negotiation, which means I had not noticed I was negotiating because nothing about the exchange indicated that a negotiation was happening.

The baht, and the small change nobody has
There are one hundred satang in a baht, and there is a satang coin in circulation, and also twenty-five and fifty. That is where the satang comes from and it is why you see prices written as a decimal.
The current coins are one baht, five baht, ten baht, twenty-five satang and fifty satang. The old one, five and ten baht notes were withdrawn years ago, which catches people out who arrive with a mental model from another country.
So a 25 satang coin is a quarter of a baht and it is the single most useful piece of small change in the country, because it lets you pay a price without triggering a request for the whole note.
Joh and song, and why they exist
Joh means ten baht and song means twenty baht, and they are used constantly, out loud, in markets, and they are the reason Thai has a price system that feels faster than a decimal one.
"Jor kor" is a hundred. "Song lo" is twenty. "Song jor" is two hundred twenty, and every stallholder in the country will use these words to move a transaction along in about a second.
You do not need to produce them yourself. You need to understand that a price ending in a round twenty or round ten is a soft price, not a fixed one, and that a vendor who says a number ending in seven is a vendor who has finished negotiating.
In the north you will also hear sao used for ten, which is a regional habit rather than a national one.
Counting
Eleven through nineteen are made from the base word, so there is no borrowing the way there is in English. Twenty-one is twenty-one, not two-one, and once you stop translating in your head the prices become much easier to follow.
And the practical part: read the number and then read the price again. The number reading is easy. The expensive part of this post is the next section.
Where prices are real and where they are not
This is the genuinely useful list, and it is short.
Fixed price, no negotiation, ever: 7-Eleven and other convenience stores, department stores, supermarkets, the big mall food courts, hospital pharmacies, and chain coffee shops. Haggling in any of these is a small social incident and you will not get a discount.
Fixed price but not marked: most restaurants, noodle stalls, food carts, and essentially all street food. The price is the price. Ask before ordering if you are unsure, never after.
Negotiable: markets, night markets, motorbike taxi drivers, tuk-tuk drivers, souvenir stalls, and small independent shops with no price tags. This is the entire list and it is bigger than visitors expect.
Costumary rather than fixed: massages, some small guesthouses, some tailors, some tour operators. These have a price that everybody knows and it is a number you discover rather than one you negotiate. Ask early and check the room rate at reception, not at the desk at one in the morning.
How to open a negotiation without being rude
The rule in a market is that the first price is not a price, it is a question, and the way to treat it is to make an offer well below it rather than to argue down from it.
So a stall marked at 300, you open at 150. Not 280, which reads as a small discount request and produces a small discount. Half is a different conversation and it is understood as a serious offer.
Then close politely and slowly. If a vendor meets you at 250, wait. If they come to 200, wait. Walking away is the strongest move available and it works, and it works because the stallholder would rather sell at 200 than not sell at all.
Buy something even if you do not agree on the price. Settle the last few baht rather than the whole amount. A vendor who feels they have lost badly will remember you, and a vendor who made a sale at a good price will too.
Buy two things from the same stall, or buy something small, if you are negotiating hard. Volume is a real lever and a 30 baht side purchase is a faster route to the price you wanted than five minutes more of haggling.
The specific traps
The fixed price that is not on the menu. Especially in tourist restaurants where the menu has no prices and the drinks are the margin. Ask the price of everything including the water before you sit down.
The taxi meter that is not started, which is covered in detail in our post on Bangkok taxis and is the single most reliable way a visitor overpays for transport.
And the gem and tattoo and tailor shops, where the negotiation is not about the object at all. Those are separate problems with separate posts.
What the round numbers actually mean
A price ending in zero, particularly twenty, forty, sixty, is almost always a soft price. A price ending in seven, nine or five is a final one, and the vendor will not move it.
A price with satang in it is often a real price, and it is frequently used deliberately: an 85 baht price signals a specific number the vendor arrived at, and round numbers signal one they are hoping you will knock down.
And nobody minds losing a negotiation, which is the thing a visitor does not believe and which is entirely true. Walking away from a market stall over price is a normal, even slightly amusing, end to a transaction. Nobody follows you.
The one habit worth building
Carry small denominations and know what a satang looks like. Nearly every bad price interaction in Thailand is really a cash-handling interaction, where a vendor cannot make change, and therefore quotes a higher number, and therefore feels they have done you a favour by rounding down from it.
A stack of twenties, fifties and a few coins eliminates an enormous percentage of the friction, and it is worth the ten seconds it takes to break a thousand before you leave the hotel.
