Payback Pillar 2 or invest externally?
A question that I cannot find answered elsewhere...
My wife and I already had offshore pensions rolling along when we arrived in Switzerland, which we've continued to add to. Since these provisions were already in place, we recently used the majority of our combined Pillar 2 funds towards the deposit on an apartment.
Now we're trying to work out, what's best... to use our monthly extra savings to pay back these Pillar 2 funds directly (tax efficient we believe but typically low annual interest rates of only 2-3%), OR invest instead in non-tax efficient mutual funds such as index funds - via brokerages such as TD Investing - where we could reasonably expect much better compounded returns over the long term.
Note: we already have Pillar 3As set-up, which we max out every year, which is why these aren't proposed.
We've rather reached the ceiling of our math knowledge, so not sure how to calculate the best approach moving forwards. Appreciate any solid advice, thanks!
