Only 7 of 77 Thai Provinces Beat Average Revenue in 2026
In short
Seven of Thailand's 77 provinces, Bangkok included, generate more revenue per registered company than the national average of 40.3 million baht. Rayong leads at 96.7 million baht per company, more than double the national figure. The other six are Prachin Buri, Phra Nakhon Si Ayutthaya, Bangkok, Chachoengsao, Samut Prakan and Samut Sakhon, all clustered around Bangkok or the Eastern Seaboard. The typical province, measured by the midpoint of all 77, sits at just 14.6 million baht per company, just over a third of the national average.
How many provinces beat the national average?
Seven. Out of Thailand's 76 provinces plus Bangkok, only seven generate more revenue per registered company than the national average of 40.3 million baht (DBD, 2026). That average is built from 80.1 trillion baht of reported revenue spread across 1,989,709 registered companies. Rayong tops the list at 96.7 million baht per company, more than double the national figure. Prachin Buri follows at 80.8 million baht, then Phra Nakhon Si Ayutthaya at 73.1 million baht. Bangkok itself ranks fourth at 62.2 million baht per company, ahead of Chachoengsao at 61.5 million baht. Samut Prakan and Samut Sakhon round out the group at 49.4 million and 43.2 million baht. The eighth-place province, Saraburi, falls to 35.9 million baht, a clean 4.4 million baht below the cutoff. Every one of the seven sits in the Eastern Seaboard industrial belt or the Bangkok metropolitan ring.

Why a handful of provinces carry the average
A national average is only useful if it describes where most of the country sits, and here it does not. The midpoint province, ranked 39th of 77, runs at just 14.6 million baht per company, well under half the national figure. That gap exists because company revenue in Thailand tracks heavy industry and port logistics far more than it tracks headcount. Rayong hosts refineries and petrochemical plants that book enormous revenue through a comparatively small number of registered entities. Samut Prakan and Samut Sakhon carry export manufacturing and processing plants that sit just outside Bangkok's city limits. Bangkok's own figure is inflated by finance, holding companies and head offices that book national revenue through a single registered address. None of this means the other 70 provinces run bad businesses. It means the national average is a weak substitute for a typical province, and any policy or investment decision built on that single number will overstate how strong the median part of the country actually is.
Definitions
- Revenue per company
- Total reported revenue for a province or for the country divided by the count of registered companies in that same area. It is an average, not a median, so a small number of very large companies can pull it well above what most companies actually earn.
- Registered company
- A juristic entity recorded in the DBD registry, whether or not it has filed a financial statement or is currently active.
- National average
- Total reported revenue for all of Thailand divided by the total count of registered companies nationwide, used here as the single cutoff line that provinces are measured against.
- Median province
- The province that sits exactly in the middle when all 77 provinces are ranked by their revenue per company, used to show what a typical province looks like rather than what the average implies.
Assumptions
- Revenue per company uses total registered companies as the denominator, including companies that have not filed a financial statement, so it is not the same as revenue per active or per reporting company.
- A small residual group of companies with no province recorded on file is included in the national total but cannot be assigned to any of the 77 provinces, so it is excluded from the province ranking.
- Company revenue is typically booked at the registered address on file, which for a multi site business may not match where the underlying operations physically sit.
Methodology
Revenue per company is total reported revenue divided by the count of registered companies, computed per province and for the whole country from the DBD registry as of 17 July 2026. The national average uses all 1,989,709 registered companies and 80,146,498,562,463.62 baht of total reported revenue as the denominator and numerator, matching the method used at the province level so the two figures are directly comparable. Companies with no province recorded, a small residual group, are excluded from the province ranking but included in the national total.
How we verified this
- National average recomputed as 80,146,498,562,463.62 baht divided by 1,989,709 companies equals 40,280,513 baht, rounded to 40.3 million.
- Each of the 77 province rows had its own average recomputed as total_revenue divided by entity_count, then compared against the national average line.
- Exactly 7 of 77 provinces exceeded 40,280,513 baht: Rayong, Prachin Buri, Phra Nakhon Si Ayutthaya, Bangkok, Chachoengsao, Samut Prakan and Samut Sakhon. 7 divided by 77 equals 9.1 percent, so 70 provinces, 90.9 percent, sit below the line.
- The eighth ranked province, Saraburi at 35,850,947 baht, was confirmed below the cutoff by a margin of about 4.4 million baht, so the count of 7 is not a close call.
- The median of all 77 province averages was recomputed at 14,608,593 baht, confirming the national average sits well above the typical province rather than near its center.
