"The inflation rate thus reached an all-time high for the second month in a row since German reunification," Georg Thiel, president of the Federal Statistical Office (Destatis), said in a written statement.
In March, the top driver of inflation was the price of energy, while the main causes of inflation in April were energy and food prices.
Food prices rose considerably for households, 8.6%, last month, while energy prices rose substantially, 35.3%.
"This is where the impact of the war in Ukraine is becoming more and more visible," the Destatis said.
On a monthly basis, consumer prices were up 0.8% in April.
