You got lucky that I have no life besides my spreadsheets Thanks for the question, as it made me revise my plan. I went back to the drawing board and I can report the following findings:
- With high salary (>130k) and 20+ years available, maxing out pillar 3 and investing all is the clear winner
- With high salary (>130k) and up to 10 years available, voluntary pension contributions and maxing out pillar 3 investments wins
- When earning less, the tax effect of pillar 2 and 3 contribution is not as marked and investing all wins.
Another interesting thing happens after retirement at age 65:
Withdrawing all capital and investing it leaves massively more money for you to spend and wealth for your heirs than leaving everything in the pension fund and getting a monthly “salary”.
Happy for anyone to review/comment my assumptions and calculations (Vorsorge vs. Investment - Google Tabellen)
