How do the rates get calculated?

JAM! handles a fixed conversion factor per worked hour. This way, you are never confronted with an additional tax. This also applies to (long term) absenteeism, vacation days, vacation money, et cetera. Our factor is all-in.

How does the conversion factor work?

The rate that you pay as a business owner is based on the conversion factor. This factor consists of the following components, among others:

  • The amount of employees
  • The amount of worked hours of an employee
  • The pension
  • The amount of vacation days
  • Included risks (for example, own risk in case of an ill employee)
  • The payrolling and HR activities you want to outsource

We calculate your rate by multiplying the gross salary of your employees with the conversion factor. Because JAM! unburdens hospitality businesses completely, you save significantly more than when you take care of all of your insurances, HR and administration by yourself or when outsourcing it to other companies.
