Our verdict
Fennel suits anyone in the US opening a retirement account who wants to trade without a commission and without a deposit floor. The trade-off is breadth and cost: markets stop at stocks and ETFs, and the account fee is $4.99 a year.

Pros and cons
Pros
- Investor protection stands at SIPC up to USD 500,000.
- The minimum deposit is $0 and stock trades cost $0, so a small amount can start.
- Support runs on email, phone and help centre, so phone, email and a help centre are all open to you.
- You can hold mobile app and web, so a portfolio is easy to check away from a desk.
Cons
- The account types are ira only, so there is no general taxable account for shares you want to hold outside a retirement wrapper.
- Markets stop at stocks and etfs, with no options, bonds, forex or crypto on the list.
- Live chat is not among email, phone and help centre, so a quick question waits for a call or an email.
Who it suits
- Anyone in the US saving for retirement, since the account types on offer are ira.
- People who prefer a plain book, with markets of stocks and etfs rather than a long instrument list.
- Investors who want a named regulated firm behind the account, listed as SIPC member 70779 in the US.
Who should look elsewhere
- Anyone who needs many asset classes: CFI covers stocks, etfs and forex.
- Anyone who wants to start with a set amount rather than small contributions: bunq lists a €10 minimum deposit.

Frequently asked questions
What does Fennel charge to hold an account?+
The account fee is $4.99 a year, charged on the retirement account that Fennel offers. Trading stocks costs $0, and the pricing model is commission-free, so nothing is taken per order. Budget for the annual fee, not for each deal.
Is there a minimum deposit at Fennel?+
The minimum deposit is $0, so there is no floor to clear before you start. That makes small, regular contributions practical, and the commission-free model means a modest first buy does not carry a dealing charge.
Which account types can I open at Fennel?+
The account types on offer are ira. That is a single retirement wrapper, so Fennel is built for long-term saving rather than for holding shares in a general taxable account. Anyone needing a taxable account should look at another provider.
Is my money protected if Fennel fails?+
Investor protection runs to SIPC up to USD 500,000. The brokerage is listed as SIPC member 70779, and the regulators named are FINRA and SIPC. That cover applies to the failure of the brokerage, not to a fall in the value of the shares you hold.
What can I trade at Fennel?+
Markets cover stocks and etfs. There are no options, bonds, forex or crypto on the list, so a portfolio built here stays simple. For a wider spread of instruments, a broker with a longer market list may serve you better.
Can I use Fennel on my phone?+
You can hold mobile app and web, so the same account works on a phone and in a browser. A mobile app is the listed feature, which suits checking a holding between other tasks rather than sitting at a desk for the trading day.
How do I contact Fennel?+
Support runs on email, phone and help centre. A phone call or an email reaches a person, and the help centre lets you answer common questions yourself. Live chat is not one of the listed channels, so a time-sensitive question has to go by phone or email instead.
Do most retail investor accounts lose money?+
Across the brokers on this comparison, 70.15% of retail accounts lose money, and in the investing ranking the figure is 72.05%. That reflects the market rather than Fennel itself, and it matters more than any fee you pay.
