Broker Fees Explained for European Investors

The short version: a "zero-commission" broker isn't automatically the cheapest. Trading commissions are only one of five cost buckets — spreads, FX conversion, custody, and inactivity fees can quietly add up to far more than a €1 order fee ever will.

This guide breaks down every fee a European broker can charge, shows the real-world impact with quick examples, and gives you a simple way to compare providers on total cost rather than headline pricing.

To compare brokers properly, start by understanding every fee that can affect your returns.

Trading commissions

This is the fee charged when you buy or sell an investment. Examples include €1 per trade, 0.10% of order value, $0.005 per share or €0 commission.

For small investors, fixed fees can have a surprisingly large impact. If you invest €100 per month and pay €2 per trade, you've already lost 2% before your investment has even started working.

This is why many long-term investors prefer brokers that offer free ETF savings plans or low-cost recurring investments.

FX conversion fees

For European investors, FX fees are often more important than trading commissions.

Whenever you buy a US stock using euros, your broker may convert EUR into USD. Examples include a 0.15% FX fee on €10,000 = €15, a 0.50% FX fee on €10,000 = €50, or a 1.00% FX fee on €10,000 = €100.

Over time, FX costs can become one of the largest expenses in an international portfolio.

Always compare FX fees alongside trading commissions.

Spreads

The spread is the difference between the buying price and selling price of an asset. Unlike commissions, spreads are not always displayed as a separate fee.

They are particularly important when trading forex, CFDs, crypto, less liquid stocks or bonds. A broker can advertise commission-free trading while making money through wider spreads.

This is one reason why comparing only headline fees can be misleading.

Custody and account fees

Some brokers charge a fee simply for holding investments on your behalf. Examples include 0.10% per year, 0.15% per year, €5 per month or no custody fee.

A 0.15% annual custody fee on a €100,000 portfolio costs €150 every year, regardless of whether you trade.

Many modern brokers have removed custody fees entirely, but they're still worth checking before opening an account.

Deposit and withdrawal fees

Most European brokers offer free SEPA bank transfers, but not all funding methods are free. Common charges include card deposit fees, instant deposit fees, international transfer fees and withdrawal fees.

For long-term investors these costs are usually less important than trading or FX fees, but they can still add up if you move money frequently.

Inactivity fees

Some brokers charge a fee if you don't use your account for a long period. This is more common among trading platforms than investment-focused brokers.

For buy-and-hold investors, inactivity fees are particularly frustrating because doing nothing is often the correct investing decision.

Before opening an account, check whether the broker charges inactivity fees and after how long they apply.

The biggest mistake investors make

Most people compare brokers like this: trading commission, trading commission, trading commission. The better approach is to calculate your total annual cost.

The cheapest broker is not always the broker with the lowest advertised fee.

A simple fee checklist

Before opening an account, compare these nine categories:

If you understand these nine categories, you'll already know more about broker pricing than most investors.

The bottom line

Broker fees rarely look expensive in isolation. The problem is how they compound over time.

A small difference in FX costs, custody fees or commissions can become hundreds or even thousands of euros over the lifetime of a portfolio.

The best broker is not necessarily the one with the lowest headline fee. It's the one with the lowest total cost for the way you invest.
