How Volatile Is Thai Corporate Profit Growth, 2007 to 2025
In short
Thai corporate net profit swung 67.23 percent higher in 2021 and then 49.33 percent lower just two years earlier in 2019. Those single year moves dwarf anything revenue growth produced across the same 18 years. Profit growth carries a standard deviation of 25.73 percentage points, nearly three times revenue growth's 8.56. Net profit fell outright in 6 of the 18 year to year transitions since 2007, revenue fell in only 4. The average yearly profit gain sits at 9.41 percent, higher than revenue's 6.3 percent, but that average sits on top of a far rougher ride.
How volatile is Thai corporate profit growth?
Ask how steady Thai corporate profit has been since 2007 and the pattern breaks apart fast. Total reported net profit ran from 918.40 billion baht in 2008 to 2.95 trillion baht in 2025, and it never moved in a straight line to get there (DBD, 2026). Net profit jumped 67.23 percent in the single year from 2020 to 2021, the sharpest rebound in the eighteen year record. Just two years earlier, from 2018 to 2019, profit collapsed 49.33 percent, the worst decline in the same span. The average of the eighteen year to year changes is a 9.41 percent gain. That average sits on a standard deviation of 25.73 percentage points, nearly three times the 8.56 point spread the site already measured in revenue growth over the identical period. Profit swings far harder than the sales figures sitting underneath it.

Why this matters
A single average growth rate flattens a genuinely rough ride. Net profit fell in a third of the years since 2007, six of eighteen transitions, while revenue fell in only four. A budget or lending model built on a smooth 9.41 percent profit assumption would have missed 2019 by roughly fifty points and missed 2021 by nearly seventy. Net margin itself ranged from 2.58 percent in 2019 to 6.62 percent in 2016, so the swing shows up on both sides of the income statement, not just at the top line. Thailand's corporate base still skews heavily toward micro and small companies with thin cash buffers, and a business built on that base feels a 49 percent profit drop very differently than one built on a diversified public market index. That gap between the headline growth rate and the real yearly experience is the number worth remembering.
Definitions
- Net profit
- Total reported bottom line profit across all companies that filed a financial statement for a given year, after all expenses and taxes.
- Year over year growth
- The percent change in a total from one statement year to the next, calculated as the difference between the two years divided by the earlier year's value.
- Standard deviation
- A measure of how spread out a set of numbers is around its average. A higher standard deviation means the yearly growth rates swing further from the typical year.
- Net margin
- Net profit as a share of revenue for the same group of companies in the same year. A margin of 5 percent means five satang of profit for every baht of revenue.
- Compound annual growth rate
- The single steady annual growth rate that would carry a starting value to an ending value over a given number of years, often abbreviated CAGR.
- Statement year
- The fiscal year covered by a filed financial statement. The registry records this in the Buddhist calendar, which this page converts to the Gregorian calendar by subtracting 543.
Assumptions
- Each year's net profit total reflects whichever companies filed a statement for that year, not a fixed panel of the same companies followed over time, so a change in the number of filers can move the total independent of the performance of continuing companies.
- The 2026 statement year, Buddhist year 2569, is excluded because only a small share of companies had filed by the time of this query.
- A single year of aggregate net profit can be pulled by a small number of very large companies, so a sharp swing does not necessarily mean the typical company experienced the same swing.
- The standard deviation reported here treats the 18 observed transitions as the full population, not a sample drawn from a larger set.
Methodology
Total net profit and reporting company counts come from market_year_insight, an aggregate table drawn from financial statements filed with Thailand's Department of Business Development, queried as of 14 August 2026. The registry records each statement under a Buddhist calendar year, which this page converts to the Gregorian year by subtracting 543, so statement year 2568 becomes 2025. Growth rates are computed year over year from the raw total net profit figures for every company that filed a statement that year, not a fixed panel of the same companies tracked across years, so entry and exit of filers can move the total independent of underlying business performance. The revenue figures used for comparison are recomputed from the same table and match the site's separate revenue volatility page. The 2026 statement year, Buddhist year 2569, is excluded because only a small fraction of companies had filed by the time of this query and the figure is not yet comparable.
How we verified this
- Recomputed the year over year percent change in total_net_profit for all 18 transitions between statement years 2550 and 2568 BE, which is 2007 to 2025 CE, from the raw figures in market_year_insight and confirmed exactly 6 were negative: 2008 at -9.26 percent, 2014 at -3.56 percent, 2015 at -6.76 percent, 2017 at -13.65 percent, 2019 at -49.33 percent, and 2023 at -19.23 percent.
- Computed the mean of the 18 profit growth rates as 9.41 percent and the population standard deviation as 25.73 percentage points, versus a mean of 6.30 percent and a population standard deviation of 8.56 percentage points for revenue growth recomputed from the same 18 transitions, confirming profit volatility is roughly three times revenue volatility.
- Confirmed the single worst transition was 2018 to 2019 at -49.33 percent and the single best was 2020 to 2021 at +67.23 percent by sorting all 18 computed growth rates.
- Confirmed total net profit rose from 1,012,086,675,198.24 baht in 2007 to 2,948,062,688,131.74 baht in 2025, a compound annual growth rate of 6.12 percent over 18 years, close to but distinct from revenue's 5.95 percent CAGR over the same span.
- Recomputed net_margin for every year as total_net_profit divided by total_revenue and confirmed the low of 2.58 percent in 2019 and the high of 6.62 percent in 2016 against the raw table values.
- Confirmed the statement year 2569 BE, 2026 CE, carries only 4,534 reporting companies and was excluded from every calculation on this page.
