Understanding commissions

What is a commission?

A commission is a service charge assessed by a broker or investment advisor for providing investment advice or handling purchases and sales of securities for a client. It’s a critical aspect of the financial services industry, and it’s important to differentiate between commissions and fees.

Commissions vs. fees

In the financial world, commissions and fees are distinct. Commission-based advisors or brokers earn money by selling investment products and conducting transactions with client funds, often receiving a percentage of the transaction as compensation.
On the other hand, fee-based advisors charge a flat rate for managing a client’s money, either as a dollar amount or a percentage of assets under management (AUM). When selecting a brokerage or advisor, understanding the nature of their compensation is essential to ensure your best interests are prioritized.

Understanding commission costs

How commissions impact investments

Commission costs can significantly affect an investor’s returns. Let’s take Susan’s example to illustrate this. She purchases 100 shares of Conglomo Corp. at $10 each. Her broker charges a 2.5% commission, resulting in a total cost of $1,000 for the shares plus an additional $25 in fees.
Six months later, Susan decides to sell her shares, and her broker charges a 2% commission on the sale, equating to $22. Although her investment earned her a $100 profit, she paid $47 in commissions on the two transactions, leaving her with a net gain of only $53.
It’s important to note that many online brokers now offer flat-rate commissions or even commission-free trading for stocks and ETFs.

The rise of commission-free trading

Today, most online brokers no longer charge commissions for buying and selling stocks. The industry has seen a significant shift towards commission-free trading, which benefits investors by reducing the costs associated with trading. Many online discount brokerages and robo-advisors have embraced this trend in the 21st century.
These services offer easy access to stocks, index funds, ETFs, and more through user-friendly platforms. They commonly charge a flat fee for trades, typically between 0.25% and 0.50% per year of assets under management.

Commission impact on investment returns

Full-service brokerages and commissions

Full-service brokerages play a significant role in the financial industry, deriving a substantial portion of their profits from charging commissions on client transactions. Each brokerage has its fee schedule for various services, and the costs associated with commissions can vary widely.
Understanding the impact of commissions on investment returns is crucial for investors. When calculating gains and losses from selling stocks, it’s imperative to account for the cost of commissions to ensure an accurate assessment of your investment performance.

Commissions and order types

Commissions can be charged when an order is filled, canceled, modified, or even if it expires. In most cases, placing an unfilled market order doesn’t result in a commission charge. However, if the order is canceled or modified, investors may incur extra charges in addition to the commission fee.
Limit orders that are partially filled often come with fees, sometimes on a prorated basis. Understanding the nuances of order types and their associated commission costs is essential for investors.

How to minimize commission costs

1. Consider commission-free alternatives

In the ever-evolving landscape of financial services, commission-free trading has become more accessible than ever. Many online brokers now offer commission-free trading for stocks, ETFs, and other investment products. Consider choosing a brokerage that aligns with your investment preferences and offers cost-effective solutions.

2. Diversify your portfolio

Diversifying your investments can help spread the impact of commission costs. Instead of concentrating on a single asset or security, consider a well-balanced portfolio that includes a mix of stocks, bonds, and other assets. This approach can reduce the frequency of transactions and, consequently, lower commission expenses.

3. Set realistic investment goals

Before making any investment, it’s essential to set clear and achievable goals. Define your investment horizon, risk tolerance, and expected returns. By aligning your goals with your investment strategy, you can reduce the need for frequent transactions and minimize commission costs.

Understanding commission structures

1. Fixed commissions

Some brokerages charge fixed commissions, which means you’ll pay a predetermined fee for each transaction. This fee may be a set dollar amount or a fixed percentage of the trade’s value. Fixed commissions provide transparency, making it easier to calculate your overall costs.

2. Variable commissions

Variable commissions are based on a sliding scale that adjusts according to the size of the trade. Larger transactions typically incur higher commission fees. Understanding the variable commission structure is crucial to assessing the impact on your investments accurately.

Commission vs. robo-advisors

1. Automated investing

Robo-advisors offer automated investing solutions that are cost-effective and convenient. They typically charge lower fees than traditional advisors, making them an attractive option for those looking to reduce costs.

2. Reduced human interaction

While robo-advisors excel in cost efficiency, they often lack the personalized touch that human advisors provide. Consider the trade-off between reduced costs and the value of human interaction when deciding between traditional advisors and robo-advisors.

The future of commissions in finance

1. Regulatory changes

The financial industry is subject to evolving regulations. Stay informed about potential changes in commission structures and fees, as regulatory adjustments can impact how brokers charge for their services.

2. Technology advancements

As technology continues to advance, financial services are becoming more streamlined and cost-effective. Keep an eye on technological innovations that may further reduce the impact of commissions on your investments.


In the world of personal finance and investment, commissions are a critical consideration that can significantly impact your bottom line. As investors, it’s crucial to understand how commissions work, their impact on investment returns, and the evolving landscape of commission-free trading. By making informed decisions about commissions and fees, you can better navigate the financial industry and ensure that your investments align with your financial goals.
