You can gain an overview of this by logging into pension.dk Under the heading "What can you expect to receive?", you can gain an overview of your pension savings at PensionDanmark. You can also access figures from your other savings accounts so that e.g. ATP and your state pension are also shown.
The figures you see show how much you can receive as the situation is now. They might become higher or lower depending on how much you set aside and the rate of interest you receive on your savings.
