Deposit protection
BUX is supervised by the Dutch Authority for the Financial Markets, the Dutch regulator listed for the firm, and trades as BUX B.V. Holdings sit under the EU investor compensation scheme, which BUX lists as EU ICS up to EUR 20,000. That is the ceiling for what the scheme pays out if the firm fails, so larger portfolios need a second plan. The scheme covers losses on investments held with the firm rather than market losses on investments that simply fall in value. Because the cap is well below larger portfolio sizes, readers with more to protect should check the cover against their own balance before they commit.
Fees and FX
Trading a share costs €3.99 and the account fee is €2.99. Currency conversion adds 0.75%, so dealing in shares priced in another currency costs more than the trade fee alone. Against the wider stock broker field, an account fee of €2.99 sits above the €0 seen at most peers, and a trade fee of €3.99 is also well past the €1.40 typical across the group. In other words, this is not a low-cost broker: the cost of using it rises quickly for anyone dealing often or in large sums. Cash left on the account is not idle, since the listed cash interest is 2%.
Markets and platforms
BUX covers stocks and etfs, so the choice is shares and ETFs rather than a wider product shelf. Investors who want to reach beyond those two asset classes would find more elsewhere, with CFI listing stocks, etfs and forex. Everything is done through BUX app, which suits people who want to trade from a phone rather than sit at a desk. The app pairs with fractional shares, so a sum smaller than the price of a whole share still buys a slice of the company, and the audience spans beginners and experienced.
How it compares on our data
Measured against the stock broker field, BUX ranks 139 on stock trade fee out of 166 brands ranked, which puts it among the more expensive names for dealing. On account fee it ranks 112 out of 142. Both positions tell the same story: the charges sit towards the expensive end of the market rather than the cheap end. That is a fair trade for simplicity and fractional dealing, but a reader who trades often will feel the difference against a low-cost broker.
The company behind it
The trading entity is BUX B.V., based in the Netherlands and founded in 2013, so the firm is a Dutch business with a decade or more of operating history. It is supervised by the Dutch Authority for the Financial Markets. Support runs on email, chat and help centre, which means help is written rather than spoken: no phone line is listed, so anyone who prefers to talk a problem through should look elsewhere. Help is aimed at both newcomers and experienced investors, matching the beginners and experienced the brand serves.

Frequently asked questions
What does it cost to hold an account at BUX?+
The account fee is €2.99. That sits above the €0 charged by most of the stock brokers on our data, so the charge is worth weighing for anyone trading only a little. Cash held on the account pays interest of 2%, which offsets part of the fee if you keep a balance.
What does a single share trade cost?+
A stock trade costs €3.99, and BUX ranks 139 of 166 brands ranked on that measure. Deals in another currency also carry 0.75% on conversion, which adds to the cost of overseas shares. Frequent dealing therefore costs noticeably more here than at the cheapest names.
Is my money protected if BUX fails?+
BUX is regulated by the Dutch Authority for the Financial Markets, and its listed investor protection is EU ICS up to EUR 20,000 under the EU scheme. That is the maximum the scheme pays, not a full balance guarantee, so portfolios larger than the cap need other cover. The scheme deals with firm failure, not market falls on investments you hold.
What can I actually buy and sell?+
The markets on offer are stocks and etfs, which means shares and ETFs. There is no forex, CFD or crypto trading listed, so anyone wanting those would need a different broker, such as CFI with stocks, etfs and forex. The low-fees model is a further reason to check what dealing costs add up to before committing.
Can I invest a small amount rather than a whole share?+
Yes. BUX offers fractional shares, so a sum smaller than the price of one share still buys a slice of a company, and fractional shares and mobile app also lists the mobile app. Everything runs through BUX app, which suits readers who want to deal from a phone. Starters can build a spread holding rather than committing to full shares.
Who is BUX aimed at?+
The stated audience is beginners and experienced, so the app is not tied to one experience level. Newcomers get fractional dealing in a single app, while more experienced investors can still use it for a straightforward share and ETF book. Support runs on email, chat and help centre, with written help rather than a phone line listed.
Does the account pay any interest?+
Cash sitting in the account earns interest of 2%, according to the listed rate. That is useful if you invest only now and then and would rather not move cash out while waiting. The trade-off is that the €2.99 account fee comes first, so the interest has to outweigh it for the account to be worth running.
