AOK Contribution Calculator (Estimate)
Use this calculator to estimate monthly statutory social insurance deductions in Germany, including health insurance (Krankenversicherung) and long-term care insurance (Pflegeversicherung).
This is an estimation tool for planning and education. Tax, church tax, solidarity surcharge, and all individual tax factors are not included.
What is an “AOK Rechner”?
An AOK Rechner is typically a contribution calculator used by employees and employers in Germany to estimate social insurance costs. AOK is one of the largest statutory health insurance providers, and many users search for tools that answer practical questions like: “How much health insurance do I pay each month?” or “What will be deducted from my gross salary?”
What this calculator includes
This page focuses on the largest employee social insurance deductions linked to gross salary:
- Statutory health insurance (Krankenversicherung), including an additional contribution rate.
- Long-term care insurance (Pflegeversicherung), including childless surcharge and Saxony adjustment.
- Pension insurance (Rentenversicherung).
- Unemployment insurance (Arbeitslosenversicherung).
To keep the tool easy to use, it does not calculate wage tax classes, church tax, or solidarity surcharge.
How the estimate is calculated
1) Monthly assessable income
We convert annual bonus into a monthly amount and add it to monthly salary. Then we apply German contribution ceilings (Beitragsbemessungsgrenzen). This means only income up to the ceiling is used for each insurance category.
2) Health insurance split
The general statutory health rate is set to 14.6% total. The additional contribution rate is entered by you (for example 1.7%). Employee and employer each pay half of the total health rate.
3) Long-term care insurance details
The base care insurance rate is assumed at 3.4% total. Employee and employer generally split this equally. If you are childless, an extra 0.6% employee surcharge is added. If you are in Saxony, the employee share is shifted upward and the employer share downward, as commonly applied there.
Why contribution ceilings matter
Many people overestimate deductions because they assume all income is always charged at full social insurance rates. In reality, ceilings cap the assessable income. If your salary exceeds the ceiling, the extra amount is not charged for that insurance branch, which changes your effective deduction percentage.
Who should use this AOK calculator?
- Employees planning net-income expectations before accepting a job offer.
- HR and payroll teams doing quick pre-checks.
- Freelancers comparing voluntary statutory insurance scenarios.
- Students and trainees learning German payroll mechanics.
Important limitations
This tool is an educational estimate, not binding tax or payroll advice. Actual payroll can differ due to tax class, child allowances, federal state, specific care insurance child discounts, mini-job rules, one-time payment handling, and legal updates during the year.
Practical tip
Use this calculator for a quick baseline, then compare with your payslip or a certified payroll system. If you are making major financial decisions (moving, changing employers, salary negotiation), validate with official sources or professional payroll advice.
