Interactive Brokers is the broker I am using and recommending. It is a great broker with very affordable prices and excellent execution.

Contrary to many brokers, Interactive Brokers (IB) has two different pricing models:

• Fixed pricing
• Tiered pricing

And many people are asking me whether they should use fixed or tiered pricing. So, we will compare these two in detail and find out!

Fixed pricing is the simplest model, you pay a fixed percentage fee, with a minimum and maximum, and that is generally it. This model is standard with most brokers.

On the other hand, tiered pricing is made of several sub fees:

• Regulatory fees
• Exchange Fees
• Trading fees
• Clearing fees

Some of these fees are per share, while others are flat, and still, others are based on the total value. And tiered pricing is very different from one exchange to the other.

So the main difference between those two is that fixed pricing is straightforward and predictable, while tiered pricing is complex and changes heavily from one exchange to the other.

Note that when you change the pricing method, it generally takes one day to apply.

The price they will pay for each transaction matters most to each investor. So, we will compare Fixed and Tiered pricing schemes for several stock exchanges. It is important to note that the location of the investors is not relevant, the pricing is done for each stock exchange. For example, a Swiss investor will pay the same price for a US stock than a French investor.

I selected various stock exchanges: the Swiss Stock Exchange (SIX), the European Stock Exchange (Euronext Paris), and the New York Stock Exchange (NYSE). These are the most used stock exchanges for a Swiss or European investor.

In some cases, there are some slight differences between buying stocks and ETFs. When this happens, the following results will use the ETF pricing.

Swiss Stock Exchange (SIX)

We start with operations on the Swiss Stock Exchange and see if fixed or tiered pricing differs.

With fixed pricing, you will pay 0.05% of the trade value on SIX, with a minimum of 5 CHF and no maximum.

With tiered pricing, you will pay 0.05% of the trade value on SIX, with a minimum of 1.50 CHF and a maximum of 49 CHF. On top of that, you will pay a trade reporting fee of 1 CHF and a clearing fee of 0.38 CHF. Finally, you will pay an exchange fee of 0.015% of the trade value plus  1.50 CHF.

With tiered pricing, you will pay even lower fees if you have a substantial monthly volume. Indeed, starting from 50 million EUR monthly volume, the fees are going down, and several thresholds exist. But we will ignore that because this does not concern most people.

So, here are the total fees for a few order sizes:

These results are pretty interesting. We can see that for small operations, the tiered pricing is slightly cheaper than fixed pricing. But once we reach 5000 CHF orders, fixed pricing becomes cheaper. And as order sizes increase, the gap between both pricing schemes grows. When we go over 500’000, the tiered pricing becomes cheaper again. And for large operations, tiered can be very significantly cheaper.

So, the cheapest way to buy on SIX is:

• Tiered pricing for small operations
• Fixed pricing for medium to large operations
• Tiered pricing for massive operations

But is worth mentioning that both models are quite affordable.

European Stock Exchange (Euronext)

Next, we look at the Euronext Paris stock exchange, one of the most used stock exchanges for European investors.

With fixed pricing, you will pay 0.05% of the trade value on Euronext Paris, with a minimum of 3 EUR and no maximum.

With tiered pricing, you will pay 0.05% of the trade value on SIX, with a minimum of 1.25 EUR and a maximum of 29 EUR. After that, you must pay exchange fees of 0.006% of the trade value, with a minimum of 0.75 EUR and no maximum. You also have to pay a clearing fee of 0.10 EUR.

Once again, here are the total fees for a few order sizes:

These results are very interesting. Below 5000 EUR, the tiered pricing is cheaper than the fixed pricing. Indeed, the tiered pricing minimum is smaller. Then, between 5000 and 50’000 EUR, fixed pricing is slightly more affordable. Finally, for 100’000 EUR, tiered pricing is cheaper again. Indeed, there is a maximum for the commissions, while fixed pricing has no maximum for the commissions.

So, to buy on Euronext Paris, you should start using tiered pricing for small operations, Fixed pricing for medium operations, and, once again, tiered pricing for large operations.

New York Stock Exchange (NYSE)

Finally, we should look at the New York Stock Exchange (NYSE), the stock exchange of the best ETFs available.

Interestingly, the commissions on NYSE are expressed per share. For this, I will assume that we buy an ETF with shares worth 100 USD. So, if we buy 1000 USD, we buy ten shares.

Also interesting is that this time, the fees differ between buying and selling. So, we first cover the buying fees.

With fixed pricing, you will pay 0.005 USD per share, with a minimum fee of 1 USD and a maximum fee of 1% of the trade value.

With tiered pricing, you will pay 0.0035 USD per share on NYSE, with a minimum fee of 0.35 USD and a maximum fee of 1% of the trade value. Additionally, you have to pay a clearing fee of 0.0002 per share. You will also pay an NYSE exchange fee of 0.003 per share. Finally, you will pay some pass-through fees. For NYSE, these pass-through fees are 0.000175 times the total of the other fees.

Putting it together, this gives us these fees for buying on NYSE:

Interestingly, Interactive Brokers’ tiered pricing is cheaper for all operations below 50’000 USD but start to be slightly more expensive for larger operations. For small operations, tiered pricing is almost three times cheaper. However, it is worth mentioning that both pricing models are extremely cheap for US ETFs.

For sale operations, there are two additional regulatory fees:

1. The SEC regulatory fee of 0.0000229 per share
2. The FINRA regulatory fee of 0.00013 per share, with a maximum of 6.49 USD

These two regulatory fees apply to both fixed and tiered pricing. So, this will not change which model is cheaper, but it is still interesting to realize the prices.

So, here is how this translates to selling on NYSE:

The tiered pricing model is generally the cheapest, up to very large operations. The gap is slightly smaller than for buy operations. However, the selling fees weigh heavily on large operations that are now several times more expensive.

For most passive investors, having more expensive sales should not be an issue. Indeed, we should buy more often than we sell.

For a small conclusion on US stock exchanges: Tiered pricing is cheaper than fixed pricing to buy US ETFs on NYSE.

We can see that neither fixed nor tiered pricing is always the cheapest option. It depends on which stock exchange you use and on the size of your transactions.

If you mainly buy US ETFs, you should use tiered pricing to save money. If you do small operations, tiered pricing is also great. Fixed pricing is excellent for medium to large operations on Swiss and European stock exchanges.

We must mention one more thing: fixed and tiered pricing models are affordable. Interactive Brokers has excellent pricing! Given these results, I plan to keep tiered pricing because I mostly use US ETFs.

What about you? Are you using Fixed or Tiered pricing?
