Best broker with cheapest fees for an ETF portfolio as a Swiss investor

UPDATE 29.10.2018
I updated this comparison in 2018 that you can find here. Nevertheless, all the information below explaining how I choose my cheapest online broker remains valid and interesting to know.

If you plan to invest your cash into the stock market, you must have faced the question of which broker to choose.
A Mustachian wants an online broker with the lowest fees in order to not eat up all of his gains.

It starts to get complex when you discover that there exist more than twenty Swiss online brokers with fees going from CHF 100/y up to CHF 2'000/y!
And that doesn't include international brokers...
There is no simple way to check costs as they depend on your investment strategy. Maybe the tool can help you but it doesn't take into account worlwide brokers that can be competitive with Swiss ones.

As I will start to re-invest my savings after a one-year break, I created a spreadsheet to find out which online broker is the cheapest one.
My comparison assumed the following Mustachian parameters:

There are several criteria you can use to rank brokers. Some are relevant, and some are futile.

Important criteria for Swiss investors to choose their online broker

Safe custody fees
Your broker charges you this price to hosts your shares and bonds.
It is either a fixed amount or a percentage of your total-portfolio value.
Some demand this recurring fees, others don't. Mustachians prefer to not pay it, obviously.
Pro tip: when doing your computation, don't forget to add the 8% of Swiss VAT to it.

Transaction fees
After the custody fees, transaction ones are the second biggest expense of an investor.
You pay them each time you buy a security. You want these expentidures to be the lowest possible.
Note that each company has its specific rate table for each security type. Your brokers ranking won't be the same if you trade currencies or bonds. We focus on ETFs in this analysis.

The not so important criteria to select your broker

Complex set of analysis tools
I remember these 90's movies where traders speculated on their five widescreen monitors. They looked smart and fancy in their Wall Street suit, staring at dashboards full of complex charts, and using stock-picking algorithms to buy and sell shares at the speed of light.
Fortunately, you Mustachians don't need any of those tools to make your money work for you.
The new "smart and fancy" is an investment strategy which allows you to stay away from the online trading platform as much as possible.
Four times a year, you'll spend thirty minutes to buy new ETFs; and once a year, you'll rebalance your portfolio. That's it. You got better to do with your time. And your portfolio will thank you when you don't sell everything because of a panic crisis during a market downturn.

Sweet user interface
Although I love well crafted user interfaces (UI) for services I use frequently, I don't take into account a broker's UI in my assessment of it.
The only thing I ask him is to be cheap. And to be functional four times a year.

From rookie to hardcore saver usecases

I detailed two Mustachian personas in my spreadsheet. Each has three variants so that it can apply to your situation no matter how much stash you have, nor how much you can invest every month.
I'm pleased to introduce you to:

  • Adrian who invests between CHF 1-3'000 per quarter, and has between CHF 10'000-60'000 already invested
  • Melanie who stashes CHF 3'000-15'000 quarterly, and has between CHF 110'000-300'000 already invested

Top 3 of online brokers for Switzerland-based investors

You surely heard of Swissquote, Strateo, SaxoBank, PostFinance and the many other Swiss brokers out there. I did the math and the result is clear: compared to the Top 3 below, they're not an alternative for us Mustachians; too expensive.

If you want to double check my findings by yourself, go to, choose whatever profile, and once on the list, click on each broker "Info" link to see the details of all their fees, such as the one of CornerTrader.

Please note that even though I think my top 3 is the best, you have to check the conditions and fees for your situation.

If you stash only a few hundred Swiss Francs every month and if you are afraid to open a brokerage account and if you are too lazy to become a millionaire, then TrueWealth might be for you.
It is a decent solution for a portfolio value below CHF 25'000, with its 0.5% of management fees. I tend to recommend it to people who still think that bank savings accounts are great — not to you, wannabee Mustachian.
Here is the link to read TrueWealth's information about fees.

  • Pros
    • ETF portfolio creation and rebalancing are done automatically
    • Perfect for for small savers (few hundred of Swiss francs set aside per month)
    • Ideal for people who don't wanna learn to trade by themselves
    • Swiss tax statement provided for free
  • Cons
    • Some of their ETFs have TER that goes up to 0.70%
    • No control of which ETFs you invest in
    • Crazy fees once you start to accumulate a decent stash (> CHF 25'000)
    • Only DE and EN user interface

Go to TrueWealth

Prior to this comparison, I invested my savings via Swissquote.
If you absolutely want a Swiss broker, I would recommend you CornerTrader nowadays.
Two key elements make them more competitive than all other Swiss online brokers: their "No custody fees" policy, and their transaction fees of 0.2% up to CHF 75'000 of stash (minimum of CHF 20/transaction) which decreases to 0.12% when over CHF 75'000 (minimum is then of CHF 18/transaction).
Follow this link to read CornerTrader's costs and conditions.

  • Pros
    • No safe custody fees
    • Cheap transaction fees
    • Swiss broker (if that's a pro to you)
    • Simple and quick process to buy securities (compared to what I experienced with Swissquote)
    • Multi-lingual user interface (way more than the usual FR-DE-EN)
  • Cons
    • None that I can think of

Interactive Brokers
I recently stumbled upon praising comments (special thanks to Mr. RIP) and positive reviews like the one from Barron's about this worldwide brokerage firm. Interactive Brokers proposes the ultimate offering for true Mustachians: no custody fees and 0.1% of transaction costs (with a minimum of CHF 10/transaction).
I recommend this broker for Mustachians who target early retirement, with way more than 100kCHF invested on the long run.
You can check the Interactive Brokers' commission fees as well as their Required Minimums.

  • Pros
    • No safe custody fees
    • Very cheap transaction fees
    • Multi-lingual user interface (way more languages than the usual FR-DE-EN)
  • Cons
    • Monthly inactivity fee below USD 100'000 stash
    • Old school user interface (yeah, I know, we said we don't care!)
    • Bank account outside of Switzerland (if that's an issue for you)

Detailed spreadsheet of online brokers' costs for Swiss residents
Like you, I'm a money nerd who trust recommendations like this "Top 3" only if they're based on data. That's why I simulated brokers' fees into the following spreadsheet. Don't hesitate to tell me if you see any inaccuracy.

MP's broker choice

There are two things I'm sure about my online broker choice: I want the cheapest fees on the long run, and I don't want to deal with the hassle of transferring securities from one broker to the other, ever.
With this in mind, the decision was easy to take. I will go for Interactive Brokers.
We will quickly get over the USD 100'000 mark so their inactivity fees isn't a blocker. I actually see it as an additionnal motivator to reach this amount as quickly as possible.

And you, what broker did or will you choose to invest your money into ETFs?

Note: if you choose to open an account at Interactive Brokers or CornerTrader via one of my links, you won't notice any difference — but the MP's blog will get a referral commission. I thank you for this.
As usual, I only write and review things that I trust and/or use in my personal daily life. In this case, the math made me end up with this Top 3, nothing else.


"Your articles are great MP, but there are so many that I don't know where to start to achieve my financial freedom. What would you recommend?"

After 1 year of deep work, here is my answer condensed in a single work:
