Gross Margin Spreads Wider Than Net Margin in Thailand 2026
In short
Yes, the spread is nearly twice as wide at the gross margin line. The middle half of Thai companies range from a 6.8 percent to a 55.7 percent gross margin as of 17 July 2026. That gap runs 48.9 percentage points. The same middle half of companies swings from a 14.1 percent net loss to a 13.4 percent net profit. That net margin gap runs a narrower 27.5 points. Gross margin's spread is about 1.8 times wider than net margin's.
Is the spread of gross margins wider than net margins?
Yes, and by a wide margin. Ranking every Thai company by its own gross margin, the 25th percentile sits at 6.8 percent and the 75th percentile sits at 55.7 percent, using the DBD registry as of 17 July 2026 (DBD, 2026). That gap runs 48.9 percentage points. Net margin covers a much tighter band. The same middle half of companies runs from a 14.1 percent net loss to a 13.4 percent net profit. That net margin gap runs just 27.5 points. Divide one spread by the other and gross margin's range comes out about 1.8 times wider than net margin's. The typical company sits at a 24.7 percent gross margin but only a 3.2 percent net margin, so the compression happens well before the median too. Every cost line that sits between the two figures, rent, payroll, depreciation, interest and tax, does real work narrowing that range.

Figures in percent margin.
Gross margin's box runs from 6.8 to 55.7 percent. Net margin's box sits mostly below it, from negative 14.1 to 13.4 percent, and it is the only one of the two that dips below zero at the 25th percentile.
Percentiles of gross margin and net margin
| Margin | P10 | P25 | Median | P75 | P90 | Interquartile spread |

| Net margin | -421.9% | -14.1% | 3.2% | 13.4% | 33.2% | 27.5 points |
Company level percentiles among the 631,892 Thai companies with both margins reported, as of 17 Jul 2026. The 10th and 90th percentiles are shown for context and run wider because a share of very small companies post extreme individual ratios.
Why this matters
This gap matters for anyone using a margin figure to size up a company. A wide gross margin range says Thai firms price and source very differently before overhead even enters the picture. A business with a scarce input or a strong brand can post 55.7 percent, a commodity trader can post 6.8 percent, and both can be perfectly viable. Net margin narrows because most of that early advantage or disadvantage gets absorbed by the same set of downstream costs almost every company carries. Thai small firms already report tight credit conditions, with banks rejecting a majority of new SME loan applications even as loan growth stays negative, and that financing pressure piles fixed interest cost on top of whatever operating expense a company already pays (OECD, 2026). A lender or investor screening on gross margin alone is only reading a company's raw commercial edge. Screening on net margin instead captures what actually survives once financing cost, fixed overhead and tax have all taken their turn, which is why the two figures tell such different stories about the same set of companies.
Definitions
- Gross margin
- Gross profit as a share of a company's own revenue. A 20 percent gross margin means 20 satang of gross profit for every baht that company earns.
- Net margin
- Net profit as a share of a company's own revenue, after operating cost, interest and tax are also subtracted.
- Percentile
- The value below which a given share of a ranked list falls. The 25th percentile is the point where a quarter of companies rank lower and three quarters rank higher.
- Interquartile spread
- The distance between the 25th and 75th percentile of a distribution, covering the middle half of companies and set apart from extreme values at either tail.
- Median
- The middle value of a ranked list, the point where half of companies rank higher and half rank lower.
Assumptions
- Figures cover the 631,892 companies that report a usable value for both gross margin and net margin, so the two distributions are measured on the same set of firms rather than two different populations.
- That sample equals 49.96 percent of the 1,264,734 companies with a filed financial statement and 31.76 percent of all 1,989,709 registered companies, so companies missing one of the two figures are not represented.
- Margins here are computed per company and ranked, which differs from the aggregate gross margin and net margin figures reported elsewhere on this site that pool total profit and total revenue across the whole economy before dividing once.
- A meaningful share of companies, about 14.70 percent of the sample, post a net margin below negative 100 percent because their revenue for the year sits extremely close to zero relative to their costs. This pulls the lowest percentiles of net margin deep into loss territory and should be read as a feature of small company accounting rather than a typical business outcome.
Methodology
Gross margin and net margin are computed per company, gross profit or net profit divided by that company's own revenue, from the DBD registry's company level financial data as of 17 July 2026. The sample is the 631,892 companies that report a usable value for both margins, so the two distributions are compared across the same set of firms rather than two different populations. Percentiles are calculated with the standard continuous method, the same approach used across this site's other per company margin pages. A minority of companies report revenue extremely close to zero relative to their costs, which pushes an individual ratio to an extreme value at the very tails of the distribution. The 25th and 75th percentiles used for the headline spread sit well clear of those tails.
How we verified this
- Recomputed the gross margin interquartile spread as 55.7369879888587 minus 6.82517049013904 equals 48.9118174987197, rounded to 48.9 points.
- Recomputed the net margin interquartile spread as 13.4411904328779 minus negative 14.062071260491 equals 27.5032616933689, rounded to 27.5 points.
- Divided 48.9118174987197 by 27.5032616933689 to get 1.7784, confirming the gross margin spread runs about 1.8 times wider than the net margin spread.
- Cross checked the sample size: 631,892 companies with both a gross margin and a net margin equal 49.96 percent of the 1,264,734 companies with a filed statement, since 631892 divided by 1264734 equals 0.4996, and 31.76 percent of the 1,989,709 total registered companies, since 631892 divided by 1989709 equals 0.3176.
- Confirmed the share of the sample with a net margin below negative 100 percent as 92,876 divided by 631,892 equals 14.70 percent, which explains why the 10th percentile of net margin runs far into loss territory even though the 25th percentile does not.

Frequently asked questions
Is the spread of gross margins wider than net margins among Thai companies?
Yes. The middle half of Thai companies spans 48.9 percentage points in gross margin, from 6.8 to 55.7 percent, as of 17 July 2026. Net margin spans a narrower 27.5 points for that same group, from a 14.1 percent loss to a 13.4 percent profit.
What is an interquartile spread and why use it here?
The interquartile spread is the distance between the 25th and 75th percentile of a distribution, covering the middle half of all values. It is used here instead of the minimum and maximum because a share of companies with revenue near zero can produce margin ratios in the hundreds of percent, and those extremes would otherwise dominate the picture.
Why would net margin be narrower than gross margin across so many companies?
Operating cost, financing cost and tax sit between the two lines and nearly every company pays some version of them. That shared layer of cost pulls high gross margin companies down and lifts low gross margin companies only a little, compressing the range by the time profit reaches the bottom line.
Does this cover every registered company in Thailand?
No. It covers 631,892 companies, the share of the 1,264,734 companies with a filed financial statement that report a usable value for both gross margin and net margin. That equals 31.76 percent of all 1,989,709 registered companies.
