Pension Fund Buy-In Calculator
Calculate how much tax you can save with a voluntary buy-in and how it affects your retirement benefits.
Save Taxes and Improve Your Pension
With a voluntary buy-in to your pension fund (2nd pillar), you can plan smartly for retirement – and save taxes at the same time. You contribute an amount of your choice within your available buy-in potential to your occupational pension. This amount is deducted from your taxable income and increases your retirement capital.
This is particularly beneficial for people with pension gaps (e.g. due to part-time work, time spent abroad, or self-employment) – but also for anyone who wants to systematically enhance their retirement provision.
Your Benefits

Save taxes
Your buy-in amount reduces your taxable income – often by several thousand francs.

Increase retirement savings
Through the buy-in, your retirement savings increase and you receive more pension or capital later.

Close pension gaps
Particularly useful for interruptions in your career or part-time work.

Flexible usage
Buy-ins can be made at any time – as a one-off or in several instalments.
