Pension fee calculator: compare two fee assumptions
Small fee differences compound over time. This calculator isolates that arithmetic by giving both scenarios the same starting balance, contributions and gross return, then changing only the annual fee assumption.

How do two fee assumptions compound?
These editable examples do not represent any provider or a permitted Pillar 3a contribution.
Each year: new balance = opening balance × (1 + gross return / 100 − fee / 100) + annual contribution. Constant returns, fees and year-end contributions; excludes taxes, inflation and other charges. Inputs are not transmitted or saved.
Where Swiss pension rules fit
The official third-pillar overview explains the distinction between restricted Pillar 3a and unrestricted Pillar 3b savings. Verify your own eligibility, contribution limits and withdrawal conditions there and with the relevant institution before making a real transaction.
