Can I calculate the enforcement exemption limit myself?

On the website of https://www.bmj.de/DE/Themen/FinanzenUndAnlegerschutz/ZwangsvollstreckungPfaendungsschutz/Pfaendungsfreigrenzen.html you can calculate the garnishment allowance yourself. You will be asked to provide information about your income, housing costs and any other garnishments that are currently active. Does your calculation differ from the ACCS calculation? If this is the case, please contact your case worker as soon as possible.
