Job ads in the Netherlands show gross pay, and landlords ask for 3 to 4 times the rent. NL Salary Lens is a free browser extension that shows what you would actually take home each month, right next to the salary and compared with your current job, on LinkedIn, Indeed and Dutch job boards, and checks rents and mortgages on Pararius, Funda and Kamernet.
€ 4.500 – € 5.500 per maand ≈ €3.427 – €3.922 net/mo
€ 72.000 – € 85.000 per jaar ≈ €4.170 – €4.676 net/mo
€ 3.800 per maand ≈ €3.080 net/mo

How it works
Salaries are found automatically in the search results and on the job page itself, including ranges like "€55.000 – €70.000", monthly amounts and "€65K". Listings that load as you scroll are tagged too.
Click the toolbar icon and tick "I have the 30% ruling". Every tag is recalculated with the tax-free 30%, applying the 2026 salary norm.
Each tag links to the take-home salary calculator with that salary filled in, where you can add holiday allowance, pension contributions and see every tax line.
Features
Set it up once with your own situation, and every salary you see is already in your numbers.
LinkedIn, Indeed and Glassdoor plus Dutch job boards and agencies such as Werk.nl, Randstad, YoungCapital and Undutchables.
Hourly and daily amounts: from €40 an hour or €320 a day they are read as a ZZP rate (net after tax and Zvw, 1,320 billable hours a year), below that as an employee's wage for 40 hours a week.
Privacy first
It reads salaries, not you. Only amounts and your settings are ever sent, to calculate net pay.
Your browser lists these when you install it. This is what each one is used for.
Install
Chrome shows a "Disable developer mode extensions" notice for any extension not installed from the Chrome Web Store. That is expected for a zip install; close it and the extension keeps working.
Download the extension (zip)Installed from the Chrome Web Store, it updates itself. Your settings and saved jobs are kept.
FAQ
It uses the 2026 Dutch income tax brackets, the general tax credit and the labour tax credit for a single income below state pension age, with no pension contribution and holiday allowance not added. Your real payslip will differ a little with pension, holiday allowance and benefits; click a tag to adjust those.
Yes, completely free. It is made by NL Tax Calculator, the same free site as the calculators.
Rentals: most Dutch landlords ask a gross monthly income of 3 to 4 times the rent, so the tag shows that range; with your current salary set it also shows what is left of your net pay. Homes for sale: a 100% mortgage of the asking price over 30 years at an example rate (not a quote), with the tax refund on the interest for your current salary, and the transfer tax for a home you will live in. Click a tag for the mortgage calculator.
The extension read that in the job ad and used it for that tag only: no holiday allowance is added when the ad says it is included, 8% is added when it comes on top, and a 13th month adds one month a year. Part-time hours are only noted, because many ads state the full-time salary.
It is below €1,000 a month, a ZZP rate while "Show ZZP rates" is off, or written in a way it cannot read (for example only in an image). Scroll a little or reload the page if a job site loaded slowly.
Firefox: yes (version 121 or newer), with the Firefox zip; until it is in the Firefox store, load it at about:debugging → This Firefox → Load Temporary Add-on. Chrome, Edge, Brave, Opera and Vivaldi use the main zip. Safari: not yet.
Open chrome://extensions (edge://extensions in Edge) and click Remove on NL Salary Lens. Its settings and saved jobs are deleted with it.
No. The extension has no ads and no trackers, and NL Tax Calculator does not sell data. What is sent, and when, is listed under Privacy above.
Install it from the Chrome Web Store, then remove the old copy in chrome://extensions (the one without a store link). The store version updates itself. Settings you made in the zip version are not carried over.
Yes. Chromium browsers install it from the Chrome Web Store too; Edge asks once to allow extensions from other stores.
For security-minded users: the SHA-256 checksum of each zip. On Windows run "certutil -hashfile <file> SHA256", on macOS or Linux "shasum -a 256 <file>", and compare.
