What Is a Brokerage Account? How It Works, What It Costs and How to Open One

What a brokerage account is

A brokerage account is an account with an investment firm — a broker — that lets you buy, hold and sell investments: shares in companies, exchange-traded funds (ETFs), bonds and sometimes funds, options or other products. You pay money in, the broker buys investments on your behalf when you place an order, and those investments are held in your name, usually through a nominee company. When you sell, the money comes back into the account and you can withdraw it.

It is different from a bank savings account in one crucial way: what you hold can rise and fall in value. Money in a savings account earns interest and, up to a limit, is guaranteed. Investments in a brokerage account aim for higher returns over time, but you can get back less than you put in.

Types of account

Most brokers offer a standard taxable account, sometimes called a general investment account. Many countries also have tax-advantaged accounts that you open through a broker, and they are often the best place to start:

• United Kingdom: the stocks and shares ISA, where gains and income are tax-free within an annual allowance, and the SIPP, a personal pension with tax relief on contributions.
• France: the PEA, a share savings plan with tax advantages after five years.
• United States: individual retirement accounts (IRAs and Roth IRAs), alongside workplace plans such as the 401(k).
• Other countries have their own rules, so check which accounts are available where you are tax resident.

How your investments are protected

Regulated brokers must keep clients’ investments and cash separate from their own money. If a broker goes bust, those segregated assets should be returned to clients rather than used to pay the broker’s creditors. If something has gone wrong and assets are missing — through fraud or bad record-keeping, for example — a compensation scheme pays up to a limit: £85,000 per person through the FSCS in the UK, at least €20,000 under the EU’s investor compensation rules, and up to $500,000, including $250,000 in cash, through SIPC in the US. No scheme anywhere covers falls in the value of your investments.

What it costs

• Commissions: a fee per trade, from nothing at many app-based brokers to several euros or pounds at traditional ones.
• Currency conversion: a charge, often 0.15% to 0.75%, whenever you buy an investment priced in another currency; for many investors this is the biggest cost.
• Custody or platform fees: some brokers charge a yearly percentage or a fixed amount just to hold your investments.
• Inactivity fees: a few brokers charge if you do not trade for a long period.
• Fund costs: separate from the broker, every ETF or fund has its own annual charge, shown as the TER or ongoing charge.

Small differences add up. On a portfolio built with €300 a month, a broker charging €3.90 per trade costs about €47 a year in commissions alone, while a broker with no commission costs nothing, before fund charges. That is why our broker reviews start with costs.

The best brokerage account is usually the boring one: regulated, cheap, and with the tax wrapper your country offers.

How to open one

Opening an account online usually takes minutes to a few days. You will typically need proof of identity, such as a passport or ID card, proof of address, your tax identification number, and answers to questions about your experience and finances, which regulators require. If you plan to buy US shares, you will usually also sign a W-8BEN form, which lets you benefit from the tax treaty between your country and the US on dividends. Check which company within the broker’s group will hold your account, since that decides the regulator and compensation scheme.

Before you open one

Investing works best on top of a cash buffer. Before you put money in a brokerage account, keep an emergency fund in an easy-access savings account and pay off expensive debt; then invest money you will not need for several years. For most people, a simple start — a regular monthly purchase of a low-cost, diversified ETF in a tax-advantaged account — beats trying to pick individual shares.
