How Many Thai Companies Can Report a Gross Margin (2026)
In short
Just 50.97 percent of Thai companies with usable financial data report enough revenue and cost detail to compute a gross margin, as of 17 Jul 2026. That covers 631,892 companies out of 1,239,733. The other 607,841, 49.03 percent, leave out enough of the cost of goods line that no gross margin can be built. A further 21,092 companies disclose a net profit without ever showing that cost breakdown. Among companies that do report one, 21,787 post a gross margin below zero, meaning they sell for less than their direct cost.
What share of Thai companies report enough detail for a gross margin?
Just over half of Thailand's financially reporting companies, 50.97 percent, leave in enough of the cost of goods breakdown to compute a gross margin (DBD, 2026). That is 631,892 companies out of the 1,239,733 with usable financial data as of 17 Jul 2026. The remaining 607,841 companies, 49.03 percent, file enough to calculate a net margin but not enough to isolate what a sale actually cost to deliver. A further 21,092 companies sit inside that gap on their own terms. They report a bottom line profit while leaving cost of goods sold blank. Revenue and net profit are the two figures Thai filings preserve most reliably. Cost of goods sold is the line that goes missing first.
How financial detail splits across Thai filers
- Zero or positive gross margin reported49.2%49
- Negative gross margin reported1.8%2
- Not enough detail to compute49.0%49
Among companies that do report a margin, the overwhelming majority land at zero or above and only a small slice fall negative, while the group with too little detail to measure at all is nearly as large as those two combined.
Gross margin reporting completeness, by group

| Not enough detail to compute | 607,841 | 49.03% |
| Total companies with financial data | 1,239,733 | 100.00% |

Why this matters
A gross margin is the plainest test of whether a business model works before rent, salaries or interest ever enter the picture. When cost of goods sold goes unreported, that test becomes impossible to run from the filing alone. Lenders, buyers doing diligence and any industry benchmark built from these filings inherit a coin flip on every second company. The split does not track company size so much as it tracks bookkeeping habit. A trading company with a thin markup has every reason to disclose cost of goods, since that line explains a low net margin. A services company with almost no physical cost of goods to book often skips the line because there is little to put in it. Treat any gross margin ranking, on this site or elsewhere, as a statement about the half of the register that chose to show its work, not about the whole economy.
Definitions
- Gross margin
- Gross profit as a share of revenue, where gross profit equals revenue minus the cost of goods sold.
- Net margin
- Net profit as a share of revenue, calculated after all costs including overhead and tax, not only the cost of goods sold.
- Cost of goods sold
- The direct cost of producing or acquiring what a company sells, excluding overhead such as rent or administrative salaries.
- Median
- The middle value once all values are sorted from lowest to highest, used here instead of the average because a small number of extreme ratios distort the average.
- Interquartile range
- The range covering the middle half of companies, running from the 25th to the 75th percentile of a measure.
Assumptions
- A company counts as having enough detail for a gross margin only when the financial ratio table carries a non empty value for it, not merely when the underlying filing contains a plausible looking cost line.
- The average gross margin across all reporting companies is not published here because a small number of extreme outlier ratios pull it to an implausible level. Median and quartile figures are used in its place.
- The 1,239,733 company base is smaller than the 1,264,734 companies DBD records as having filed a financial statement, since about 25,001 filers lack enough data to compute even a net margin and sit outside this ratio table.
- This page counts reporting completeness only. It makes no claim about whether a company's cost of goods figure, where present, is accurate.
Methodology
Gross margin completeness is measured across the Max Data financial ratio table built from DBD-filed financial statements, as of 17 Jul 2026. A company counts as having enough detail when that table carries a computed gross margin value. A company counts as missing that detail when the gross margin field is empty, even where a net margin can still be computed from the bottom line alone. This base of 1,239,733 companies is smaller than the 1,264,734 companies DBD records as having filed a statement, because about 25,001 filers lack enough data to compute even a net margin and fall outside this ratio table entirely. Median and quartile gross margins are reported instead of an average, because a small number of extreme outlier ratios pull the average to an implausible level and make it unusable as a summary.
How we verified this
- 607,841 divided by 1,239,733 equals 49.03 percent, and 631,892 plus 607,841 sums to the full base of 1,239,733.
- 631,892 divided by 1,239,733 equals 50.97 percent, the exact complement of 49.03 percent.
- 610,105 plus 21,787 equals 631,892, so the zero-or-positive and negative gross margin groups fully account for every company with a computable margin. 21,787 divided by 631,892 equals 3.45 percent.
- 610,105 divided by 1,239,733 equals 49.21 percent and 21,787 divided by 1,239,733 equals 1.76 percent. 49.21 plus 1.76 plus 49.03 equals 100.00 percent, closing the three way split shown in the chart and table.
- 21,092 divided by 1,239,733 equals 1.70 percent. Every company with a gross margin also carries a net margin in this table, since 631,892 plus 21,092 equals 652,984 companies with a net margin, and 652,984 plus the 586,749 companies with a null net margin equals the full base of 1,239,733.

Do any Thai companies report a negative gross margin?
Yes. 21,787 companies, 3.45 percent of those with a computable margin, report a cost of goods figure larger than their revenue.
What is the typical gross margin among companies that report one?
