Hi bighead,
The retirement fund comparison only includes mutual funds which are eligible to be used for pillar 3a assets.
If you will be investing outside of the pillar 3a, there are other funds (namely a number of ETFs) which have lower TERs (fund management fees) than the pillar 3a-eligible funds included in the comparison.
If done right, investing in the right ETFs using the right broker is the most affordable way to invest in funds. The lower your costs, the higher your potential returns on investments.
But investing in ETFs is only a good idea if:
1. You are comfortable with researching fund performance and costs yourself. Performance reports for ETFs are fairly easy to find, but it can be very difficult to find and compare costs.
2. You are willing to open a stock brokerage account.
3. You are comfortable with buying ETF shares directly yourself.
4. You do not act emotionally and will not sell your ETF shares immediately when prices fluctuate.
5. You use a broker with low brokerage fees and low or no custodial fees. Any fees charged by your broker are an added expense on top of fund fees. As a general rule, you will normally pay less in brokerage fees if you build up cash and then buy ETF shares in bulk (every 3, 6 or 12 months, for example) rather than buying a small amount of shares every month.
When conventional funds from banks or insurance providers are a better option:
If you prefer not to invest yourself using a broker, then using the most affordable conventional funds is a good alternative. The benefit of using conventional funds is that you can get consultation in person at branch offices of the bank which offers the funds. The bank also takes care of everything for you. You don't have to use a third-party broker, so you do not need to calculate the cost of brokerage fees into the equation.
Another benefit is that, depending on the bank, selling conventional fund shares may require more effort (i.e. you may have to visit a bank branch). This makes it more difficult for you to make impulse share sales (which is very easy to do with ETFs and online brokers).
As you rightly noted, PostFinance offers some affordable conventional funds. Although the retirement fund comparison only includes pillar-3a eligible funds, it provides a good reference for comparing the costs of conventional mutual funds from Swiss banks and insurance providers as a whole.
