What Is Commission in the Stock Market? Key Aspects and Examples

Learn about commission in the stock market, its key aspects, and examples. Understand how commission impacts trading costs and the evolution of commission structures in the stock market.


Commission in the stock market is a fee paid to brokers for executing buy or sell orders on behalf of investors. It is essentially the cost of accessing the services of a brokerage firm to facilitate the trading of stocks, bonds, or other securities. The commission is charged either as a flat fee per trade or a percentage of the total value of the transaction. This fee structure varies among brokerages, with some offering low or even zero commissions as a way to attract clients.

Key Aspects of Commission:

1. Fee Structure:

  • Flat Fee: A fixed amount charged for each trade, regardless of the trade's size.
  • Percentage: A specified percentage of the total trade value.

2. Impact on Trading Costs:

Commissions are an essential consideration for investors, especially those who trade frequently, as they add to the total cost of trading and can impact overall investment returns.

3. Negotiable Commissions:

In some cases, especially for high-volume traders or institutional investors, commission rates may be negotiable with the brokerage.

Example of Commission:

Let's consider an example involving HDFC Bank shares:

  • Flat Fee Commission: Suppose a brokerage charges a flat fee of ₹20 per trade. If an investor buys 100 shares of HDFC Bank at ₹1,500 per share, the total cost of the transaction before taxes would be ₹1,50,020 ([100 shares * ₹1,500 per share] + ₹20 commission).
  • Percentage-Based Commission: If another brokerage charges a 0.5% commission on the total trade value, the commission for the same trade would amount to ₹750 (0.5% of ₹1,50,000). Hence, the total cost of the transaction would be ₹1,50,750.

Evolution of Commission in the Stock Market:

Traditional Full-Service Brokers:

Initially, full-service brokers dominated the market, offering comprehensive services, including investment advice, portfolio management, and trade execution, with relatively high commission rates.

Discount Brokers:

The emergence of discount brokers, who offer lower commission rates for self-directed trading without the additional advisory services, revolutionized the industry and made trading more accessible to the average investor.

Zero-Commission Trading:

In recent years, a growing number of brokers have started offering zero-commission trades for stocks and ETFs, making money through other channels like payment for order flow, interest on uninvested cash, and ancillary services.

Conclusion:

Commission fees are a critical consideration for anyone participating in the stock market. With the evolution of brokerage services and the advent of zero-commission trades, investors have more options than ever. Nonetheless, it's essential to understand not only how much you're paying in commissions but also to consider the overall value and quality of the brokerage services you receive. Always compare the fee structures of different brokers and understand their terms before executing trades to ensure that you're getting the best possible deal.
