Mini-Job vs. Working Student Job: What Do You Really Keep?

Reading time: 8 minutes
You face a choice: a 538 euro mini-job or a working student job (Werkstudentenjob) at 16 euros per hour? At first glance, the mini-job vs. working student comparison seems simple. But I'll tell you from experience: what's on paper and what lands in your account are two completely different numbers. Last week Lukas, a computer science student in his fifth semester, told me he earns 1,280 euros gross as a working student. In the end he keeps 1,087 euros net. His fellow student Tom works a mini-job at the checkout and gets exactly 538 euros paid out, with no deductions.
The difference? Lukas works 20 hours per week, Tom only 10. But is more work automatically more money? Not always. Today I'll calculate which side job as a student is really worth it financially, which hidden costs are coming your way, and when you're better off keeping your hands off a working student job.
Mini-job: what's left net from a 538 euro job?
Since January 1, 2025, the mini-job limit in Germany has been 538 euros per month. That means: everything you earn lands in your account. No income tax, no social security contributions, no nasty surprises on the payslip. Your employer pays flat-rate contributions to the Minijob-Zentrale, but that doesn't come out of your pay.
Example: you work as a server at Dean & David in downtown Munich for 13 euros per hour. At 41.38 hours a month, you reach exactly 538 euros. Your net? 538 euros. Done. No calculation, no fine print.
The biggest advantage of a mini-job: you stay under most radar systems. Your health insurance through family coverage stays in place as long as you work under 20 hours per week. And with many employers you get tips on top, which show up nowhere.
When you need to watch out with a mini-job
The 538 euros is a hard limit. If you earn even 539 euros, the whole system tips over. Then you are subject to social security contributions and pay in retroactively on the entire amount. I experienced this in my second semester: a colleague worked two extra shifts in the run-up to Christmas, reached 612 euros and ended up having to pay 87 euros back to the health insurer.
Working student: how much do taxes and social security eat from your pay?
As a working student you may work a maximum of 20 hours per week during the semester. Your pay? Often between 13 and 18 euros per hour, depending on the industry and city. Sounds good at first, but this is where deductions come in that many people underestimate.
A concrete calculation for Berlin: you work 20 hours per week as a working student at a marketing agency in Kreuzberg, at an hourly wage of 16 euros. At 4.3 weeks per month, that is on average 1,376 euros gross. What you actually receive:
- Pension insurance: 9.3 percent = 127.97 euros
- Income tax: with tax class I and under 2,000 euros usually 0 euros (you get it back through your tax return)
- No health insurance, no long-term care insurance, no unemployment insurance (that is the working student privilege)
Your net: about 1,248 euros. You get the income tax back in full the following year if you stay under the basic tax-free allowance of 11,784 euros per year.
The hidden trap with health insurance
Many people forget: as a working student you are still covered by student health insurance and pay about 122 euros per month yourself. That eats up part of your extra earnings. Mentally add these 122 euros to your deductions, and you'll see the real picture.
The direct net comparison: mini-job or working student as a student
I'll put both scenarios side by side so you can see what really counts. Assumption: you have 10 hours per week for a side job.
Mini-job option: 10 hours at 13 euros = 520 euros gross = 520 euros net. No deductions, no discussion.
Working student option: 10 hours at 16 euros = 688 euros gross. After deducting 9.3 percent pension insurance (64 euros), 624 euros net remain. Sounds better, right? But now comes the catch: if the working student job knocks you out of family coverage and you have to pay 122 euros for health insurance yourself, you really keep 502 euros. That is less than with the mini-job.
When is a working student job worth more than a mini-job? Only from about 15 hours per week or an hourly wage above 17 euros. Below that, health insurance eats up your advantage.
Mini-job vs. working student: the health insurance difference

This is the crux that many people overlook. With a mini-job you stay in your parents' family health insurance as long as you earn under 538 euros per month and work under 20 hours per week. It costs you: 0 euros.
As a working student you are likewise exempt from health, long-term care and unemployment insurance, but only as long as you stay under 20 hours per week. You still pay the student health insurance yourself, currently about 122.40 euros per month at TK (as of March 2025, source: Techniker Krankenkasse).
If you earn more than 538 euros as a working student, you have to leave the family insurance. That happens automatically. The health insurer gets in touch with you, often only after two or three months. Then you pay retroactively. I know cases where students suddenly had to pay back 480 euros in the fourth month.
What most people get wrong
They only compare gross against gross. But health insurance isn't an optional luxury, it's mandatory. If you were covered by family insurance before and now pay 122 euros per month, that is a real cut to your disposable income.
Tax differences: what you get back and what you don't
With a mini-job there is no tax return for you. Your employer pays a flat 2 percent income tax, but that is their problem, not yours. You hand over nothing, you get nothing back. Simple.
As a working student it looks different. With higher income you pay income tax, which is deducted automatically. But: if your income for the whole year stays under 11,784 euros, you get every cent back. You file the tax return through ELSTER (the German online tax portal), it takes two hours, and after three months the money is in your account. Last year, for a working student job from January to August, I got 487 euros of income tax back.
You can also deduct work-related expenses: commuting to work, work equipment, even part of your laptop. The flat allowance is 1,230 euros per year, without needing any receipts. If you have higher costs, collecting receipts is worthwhile.
BAföG and side jobs: how the mini-job vs. working student comparison affects your funding
If you receive BAföG (German state student aid), the earnings limit is 6,251 euros per year (as of 2025, source: Federal Ministry of Education and Research). That is about 520 euros per month. A mini-job at 538 euros is just above it, but you have an allowance that cushions this. In practice: with a mini-job of up to 538 euros you usually get no reduction.
With a working student job it gets more complicated. If you earn 1,200 euros per month, you are at 14,400 euros per year, far above the limit. Your BAföG is reduced, and not by a little. For every euro over the limit, you lose about 50 cents of BAföG. If you used to get 500 euros of BAföG, after a year of a working student job there may suddenly be only 200 euros left. I have written a more detailed article on this that you should take a look at: Working student and BAföG: how many hours are allowed?
Flexibility and career: what the mini-job vs. working student comparison doesn't show

Numbers aren't everything. A working student job in your field of study gives you practical experience, contacts and often a direct way in after graduation. I know three people from my year who were taken on straight from their working student positions after the bachelor's, without a traditional application.
A mini-job at the supermarket checkout pays on time and is stress-free, but does nothing for your career. That's okay if you just need money and would rather invest your time in your studies. But if you have to work anyway, a working student job can be the better investment, even if you end up with 50 euros less in the end.
Flexible hours in practice
Mini-jobs are often more rigid. You have fixed shifts that can't be moved around exam periods. Working student jobs, especially in IT or marketing, often allow flexible working hours, working from home and fewer hours in stressful weeks.
My conclusion: which side job brings in more net
If you work under 12 hours per week, are covered by family insurance and don't receive BAföG: take the mini-job. You have less paperwork, no tax return, no worries about insurance.
If you have 15 to 20 hours available, get a good hourly wage (over 16 euros) and want to gain work experience: working student job. The 122 euros of health insurance hurts, but you make it back through higher pay and later career opportunities.
If you receive BAföG: be careful with both options. The mini-job is safer here because you stay under the earnings limit. The working student job can wreck your funding if you're not careful.
And if you want to build up other financial cushions alongside your studies: take a look at how to plan your emergency fund for your studies, or whether a continuing education program with funding pays off more in the long run than any side job.
Frequently asked questions about the mini-job vs. working student comparison
What's left net from a mini-job?
With a mini-job, 100 percent of your gross pay stays as net pay, currently a maximum of 538 euros per month. There are no deductions for taxes or social security on your side. Your employer pays flat-rate contributions that don't affect you.
Is a working student job worth more than a mini-job?
From about 15 hours per week and an hourly wage above 16 euros, you earn more as a working student, even after deducting pension insurance and health insurance. Below that, the 122 euros of health insurance often eats up the advantage, especially if you were covered by family insurance before.
How much tax do you pay as a working student?
Income tax depends on your annual income. Under 11,784 euros per year you effectively pay zero euros, because you get everything back through the tax return. Above that, you pay tax on the excess amount under tax class I, usually between 10 and 20 percent.
Can I combine a mini-job and a working student job?
In theory yes, in practice it gets complicated. Both jobs together must not exceed the 20-hour limit, otherwise you lose your working student status. In addition, the incomes add up for BAföG and family insurance, which can cause problems.
What happens if I earn over 538 euros as a mini-jobber?
You automatically become subject to social security contributions. That means deductions for health, pension, long-term care and unemployment insurance on the entire amount, not just on the excess. You pay retroactively as soon as the Minijob-Zentrale or your health insurer notices, often only months later.
