Open a step for the sum with your figures, what the step does, and what the Dutch terms mean.
What this step does: Not all of your gross salary is taxed: your own pension contribution is taken off first, and with the 30% ruling the tax-free part too. Holiday allowance counts as salary.
What this step does: Box 1 is the tax on income from work and your home. The income is cut into brackets and each slice is taxed at its own rate, so a raise never lowers your net pay through the brackets alone. Then the tax credits (heffingskortingen) are taken off the tax itself.
What this step does: What reaches your bank account: gross salary minus the income tax after tax credits. In practice your employer withholds this every month as wage tax (loonheffing).
What this step does: Your profit is what the business earned after its costs. This is the starting point for every tax a freelancer pays.
What this step does: Entrepreneurs who are in business for themselves get deductions that ordinary employees don't. They are taken off the profit before income tax is worked out, so they lower the tax, not your revenue.

The labour tax credit is based on the profit before the deductions.
What this step does: What you actually keep: the profit minus income tax and the income-related health-care contribution (Zvw), which freelancers pay themselves.
What this step does: The results of each option put next to each other on the same basis, so the difference is only the choice itself.
Should I just charge more as a freelancer to match a salary?
Many freelancers do exactly that - see "Why freelance revenue usually needs to be higher" above for the rough markup to consider, then re-run this calculator with the higher revenue figure.
Does this include mandatory freelancer insurance costs?
No - arbeidsongeschiktheidsverzekering (AOV) and any private pension contributions are not subtracted from the freelancer side. Budget for them separately; they typically run several thousand euros a year.
Can I use this for a specific day-rate decision?
Yes - multiply your day rate by your expected billable days per year for the revenue figure, subtract your real expected business costs, and compare against the salary of an equivalent employee role.

Both sides use the same simplified assumptions as the standalone Freelancer and Take-Home Salary calculators (single filer, standard deductions only). This does not model the value of things employees get "for free" that freelancers must fund themselves - continued pay during illness, employer pension contributions, unemployment insurance (WW) - see the guide below for what to add mentally before comparing.
