What a localization team actually costs, fully loaded
Fully loaded cost has four components: headcount, vendor spend, tooling, and the engineering time internationalization consumes. Most budgets capture the first three and miss the fourth, which is frequently the largest. This page sets out the model; the benchmark figures are published with the salary report.

What are the components of localization cost?
Four, and they behave differently. Headcount is fixed and grows in steps. Vendor spend is variable and tracks content volume. Tooling is fixed and usually modest. Engineering time is variable, invisible in most budgets, and frequently the largest single item in the first two years.
A budget that models only the first three will be wrong in a predictable direction: it will understate the true cost of entering a market and overstate the savings from cutting vendor rates.
- Headcount, fully loaded
- Salary plus employer taxes, benefits, equipment and recruitment cost.
- Vendor spend
- Translation, review, and specialist services, priced per word, per hour or per project.
- Tooling
- TMS, terminology and QA tooling, and machine translation. Usually the smallest line and the one most often over-scrutinized.
- Engineering time
- Internationalization work, pipeline integration, defect fixing and release support. Rarely charged to the localization budget and rarely small.
Why is engineering time the item that gets missed?
Because it is spent by a different team, against a different budget, and usually before anyone calls the project localization. Extracting hard-coded strings, replacing concatenated sentences, making layouts tolerate text expansion and building the pipeline are engineering tasks, and they land on an engineering roadmap.
The consequence is systematic. Companies compare vendor quotes carefully and approve internationalization work casually, when the second is the larger and less reversible commitment. A product that was internationalized properly makes every subsequent market cheap; one that was not makes every market expensive, permanently.
How does the cost shape change as a company grows?
Early on the cost is almost entirely vendor spend and engineering time, with no dedicated headcount. The first hire is usually a project manager, and it is justified by the coordination overhead already being absorbed by people whose job is something else.
As volume grows, the ratio inverts: headcount and tooling rise, and vendor spend per unit of content falls as leverage from translation memory and machine translation increases. The steady state most companies reach is a small internal team directing a much larger external supply base.
What does AI change about the cost model?
It compresses the vendor line and moves cost into supervision. Machine translation reduces cost per word substantially for content that tolerates it, which means the savings are real but concentrated in the tiers where quality requirements were lowest.
What it does not reduce is the cost of deciding: what quality each tier needs, whether output is fit to ship, and who is accountable when it is not. That work is headcount, and it is the part of the budget that grows while the vendor line shrinks.
The net effect for most companies is a smaller total spend with a different shape — less production, more supervision and evaluation. Budgets written on the old shape tend to cut the wrong line.
What are the benchmark figures?
Published with the Talent Insights Report, segmented by role, region and seniority, with the sample size and collection period stated on every figure.
Ranges are deliberately not published here in the meantime. A cost model is useful without numbers; a cost model with numbers that cannot be sourced is worse than useless, because it will be quoted.
