Hi
I have done yet another calculator: A calculator to compare a second pillar contribution with an investment in free assets:
thepoorswiss.com
This will compute the difference over time based on your marginal tax rates, your returns, and the withdrawal tax. And it also gives you the break point where one becomes more interesting than the other.
This should help people decide whether they should contribute to their second pillar or not.
Let me know what you think

This calculator will tell you whether a contribution to your second pillar makes sense financially or whether you should invest in free assets instead.
