In general, it makes sense to have figures from the most recent 3-year period in order to identify and correct for possible fluctuations.

When it comes to trends, it is advised to be on the lookout for high deviations or one-off payments. Ways to deal with such scenarios are:

• Clarifying the reason for the discrepancy
• Requesting figures for a longer period
• Requesting a forecast (this should be considered with caution)
• Neglecting certain extremes or one-off payments in the calculation or taking them only partially into account
• Evaluate income development to identify any trend

When the contractually granted, basic salary of an employed person increases, the new salary can be used in the calculation.
