What is the difference between AOW and a company pension?

AOW is the state basic pension, the first pillar. Everyone living or working in the Netherlands accrues AOW, regardless of income or profession. It is a fixed amount, not a percentage of your salary.

A company pension comes on top and does depend on your income and your scheme. For most people AOW alone is not enough to maintain their standard of living. Read when do I get AOW.
