TypeScript is the second most-used and most wanted language in the Netherlands after JavaScript and Python, respectively. Here, we’ll look at average TypeScript developer salaries by experience and how they compare to the average JavaScript developer.


The average junior TypeScript developer earns €40 104 per year if they have at least two years of experience, €240 or 0.6% less than their JavaScript counterparts.

TypeScript developers receive the most significant pay increase of their careers once they pass the four-year experience mark: Mid-level TypeScript developers in the Netherlands with at least four years of experience can expect a 24.2% pay increase giving them an average annual salary of €49 790.

At this stage of their careers, they’re earning €3 333 or 7.2% more than the average for JavaScript.

Why the significant increase? First, developers typically change jobs more frequently at this stage of their careers. This gives them a chance to negotiate a higher market-related salary than the inflationary increases developers can expect if they stay with one company.

Companies hiring developers at these career stages are more inclined to offer what might seem a significant increase because the salary range is still not that high.

Salary growth for senior TypeScript developers begins to slow once they pass the 6-year mark. However, that’s not to say there’s no growth.

A senior TypeScript developer’s salary increases by 15.6% after they’ve been coding for at least six years. This gives them an average annual salary of €57 574, a nominal 1.1% or €654 more than the typical JavaScript developer.

They can also look forward to an additional 13.6% increase to an average of €65 391 after coding for at least ten years. As a result of this increase, the gap between them and their JavaScript counterparts has widened to €5 075 or 8.4%.

Why does salary growth slow for senior TypeScript developers? It’s standard for senior developers to experience a slowdown at this level of their careers, regardless of their tech stack. In addition to senior developers generally changing jobs less often than juniors, companies usually consider salary increases more carefully as a developer’s salary level becomes “more expensive”.

Keep in mind

The data in this article is taken from StackOverflow’s 2022 Developer Survey’s open data. In this article, ‘salary’ refers to the gross annual salary (before tax) provided by 234 survey respondents from the Netherlands who identified as TypeScript developers.

We only included salary insights for experience levels with enough data points to ensure that the amounts represent TypeScript developers in the country. That’s why we excluded salaries for developers with fewer than two and more than fifteen years of experience in this article.

We also ran an outlier analysis to identify data points skewing the distribution of salaries. These points were removed from the final dataset to ensure that the amounts are representative of TypeScript developers in the Netherlands. We’ve also included the 25th and 75th percentiles to give you further information about the distribution of salary data.

Average salaries are single data points and only one part of a bigger story. Many respondents may earn significantly more or significantly less than these averages. However, we hope to show underlying trends by mapping the average salaries for different experience levels.

These averages should not be used to estimate what your actual salary will or should be. Salaries depend on the company size, industry, individual, perks and nature of the work. These factors all influence the salary a company will offer to a prospective hire. In addition, most developers are “fluent” in several languages and work across multiple roles, which will also affect the final figures.

It’s also important to remember that every individual’s context is different. Salary is a personal conversation that should take place between employee and employer.

On OfferZen you can hire TypeScript developers and find TypeScript developer jobs.
