How do I calculate my salary increase in percent?

Formula: (New salary - Old salary) / Old salary x 100 = increase in percent. Example: 4,000 to 4,300 euros = 7.5%. Reference values for Germany from Destatis: collective agreement wage growth is 3–5% annually in 2024–2025. Inflation (also Destatis) erodes real purchasing power — an increase below the inflation rate is effectively a real wage loss. BA Entgeltatlas: market development for your occupational group provides guidance on whether your increase is above or below the market average. Rule of thumb for negotiation: start with double your target — do not ask for ten percent if you want ten percent.
