Only 3 Provinces Beat Bangkok on Revenue per Firm, 2026
In short
Only three provinces generate more revenue per registered company than Bangkok as of 17 July 2026. Rayong leads at 96.7 million baht per company, followed by Prachin Buri at 80.8 million and Phra Nakhon Si Ayutthaya at 73.1 million. Bangkok manages 62.2 million baht per company, good for fourth place among 77 provinces. That is despite Bangkok holding 812,799 registered companies, or 40.9 percent of the national total. Counting companies and measuring money per company tell two different stories about where Thailand's economy actually runs hardest.
How many provinces earn more per company than Bangkok?
Three do, as of 17 July 2026 (DBD, 2026). Rayong tops the ranking at 96.7 million baht of revenue for every registered company. Prachin Buri comes next at 80.8 million, then Phra Nakhon Si Ayutthaya at 73.1 million. Bangkok follows in fourth place at 62.2 million baht per company, measured across all 77 provinces including the capital itself. The margin over fifth place is thin. Chachoengsao sits just behind Bangkok at 61.5 million, a gap of only 1.1 percent. Bangkok's spot in the top four is real, but it is not comfortable.

Why the company map and the money map disagree
Bangkok's 812,799 registered companies equal 40.9 percent of the national total of 1,989,709 (DBD, 2026). No other province comes remotely close to that share. Yet those companies produce 63.1 percent of national reported revenue, a share that runs well above their share of the register. Both facts sit on the same table and both are true. Bangkok is the country's largest single pool of revenue by a wide margin, and it is only the fourth best address in Thailand when the question is how much a single company there earns on average. A typical Rayong company generates 56 percent more revenue than a typical Bangkok company. A typical Bangkok company still earns 54 percent more than the national average of 40.3 million baht per company. Scale and efficiency answer different questions, and this data answers both at once. Rayong, Prachin Buri and Ayutthaya carry heavy industrial and manufacturing bases built around a smaller number of large filers, while Bangkok's revenue comes from a far larger and more varied population of firms, including many small ones that pull its average down even as its total stays enormous. For anyone deciding where to put capital to work rather than just where to put a mailing address, the three provinces ahead of Bangkok are worth a second look.
Definitions
- Revenue per company
- A province's total reported revenue divided by its count of registered companies. It measures average scale per firm, not profitability.
- Registered company
- A juristic entity recorded in the DBD registry under a given province, regardless of whether it is currently active or has ever filed a financial statement.
- National average revenue per company
- Total national reported revenue divided by the total number of registered companies with a known province, used as the baseline for comparing any single province.
Assumptions
- Revenue figures reflect whatever financial statements are on file with the DBD as of the data date, so provinces with lower filing rates may understate true activity.
- A company's registered province is its address of incorporation, which can differ from where it actually operates or books revenue.
- About 572 companies nationwide carry no listed province code and are excluded from every provincial total and share in this analysis.
Methodology
Revenue per company divides each province's aggregate reported revenue by its count of registered companies, using Department of Business Development registry aggregates as of 17 July 2026. The registered company count for a province includes every juristic entity recorded there, regardless of size or current activity status, and revenue reflects the total of reported figures on file for companies in that province. National totals and shares exclude a small number of records with no listed province code, about 572 companies nationwide, so they do not change the provincial ranking. Figures are aggregate sums, not the average of individual company margins.

Frequently asked questions
Which provinces earn more revenue per company than Bangkok in 2026?
Only three, as of 17 July 2026: Rayong at 96.7 million baht per company, Prachin Buri at 80.8 million, and Phra Nakhon Si Ayutthaya at 73.1 million, all ahead of Bangkok's 62.2 million.
Does Bangkok have the most registered companies in Thailand?
Yes. Bangkok holds 812,799 registered companies, equal to 40.9 percent of the national total of 1,989,709, far more than any other province.
If Bangkok has so many companies, why does it rank only fourth on revenue per company?
Company count and revenue per company measure different things. Bangkok's huge base of firms of every size pulls its average down, while Rayong, Prachin Buri and Ayutthaya carry a smaller number of large industrial and manufacturing filers that push their averages up.
How close is Bangkok to dropping out of the top four?
Very close. Chachoengsao, in fifth place, trails Bangkok by only 1.1 percent on revenue per company, a gap that a single reporting cycle could close.
