45.7% of software developers in the Netherlands list JavaScript as a primary programming language. This makes it the most widely used language in the country, ahead of TypeScript and Java. Here, we’ll look at what JavaScript developers in the Netherlands earn at each stage of their careers.


Average entry-level and junior JavaScript developer salary trends

Entry-level JavaScript developer salaries in the Netherlands start at €32 151 per year. After two years in the profession, junior JavaScript developers see their salaries rise by 25.5%. This is the most significant pay rise of their careers and gives them an average annual salary of €40 343. At this stage of their careers, they earn a nominal 0.6% more than their TypeScript counterparts.

Why the significant increases during the early stages of their careers? Junior developers typically change jobs more frequently. 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 compared to those for more experienced developers.

Depending on how quickly they progress, JavaScript developers might also fast-track their levelling up to a mid-level developer. Mid-level JavaScript developers who pass the four-year experience mark can look forward to an additional salary increase of 15.2%. This gives them an average salary of €46 457, 6.7% less than the average for TypeScript developers with comparable experience.

Average Salary by Years Experience, showing 25th and 75th percentiles
Years of Experience 25th Percentile Average 75th Percentile
0-2 €28,800 €32,151 €34,200
2-4 €33,300 €40,343 €45,809
4-6 €37,425 €46,457 €54,475
6-10 €45,000 €56,920 €67,000
10-15 €48,432 €60,316 €76,732

Salary growth for JavaScript developers in the Netherlands initially picks up once they reach the senior level: Senior JavaScript developers with six to ten years of experience see their salaries increase by 11.5% to €56 920 per year. As a result of this increase, they’ve narrowed the gap between themselves and senior TypeScript developers to 1.1%.

Average salaries for JavaScript developers increase by an additional 6% to €60 316 after more than ten years in the profession, 7.8% less than their TypeScript counterparts.

Why does salary growth slow down for senior developers? In addition to senior developers generally changing jobs less often than juniors, companies are less inclined to offer big increases on larger salaries.

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 259 survey respondents from the Netherlands who identified as JavaScript developers.

We only included salary insights for experience levels with enough data points to ensure that the amounts represent JavaScript developers in the country. That’s why we excluded salaries for developers with 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 JavaScript 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.
