The Federal Statistical Office (StBA) is a German higher federal authority. It collects, collates and analyses statistical information on the economy, society and the environment, and provides information on value protection clauses, among other things.

If you have a contract with a capitalization clause, you can use the calculation help to determine whether an adjustment can be made. For example, you can determine whether a rent increase is due or whether the amount of maintenance payments can already be adjusted.

To do this, you must enter the values from your contract in the calculation help. Among other things, you have to enter

  • The calculation method,
  • The index on which the calculation is based,
  • the amount of the necessary index change,
  • the reference date and
  • the calculation time.

This way, you do not have to worry about the actual calculation, omitted indices and calculation bases.

You must call up the information for indexation clauses online from the Federal Statistical Office (StBA).
