A commission fee is a payment tied to completing a transaction, most often calculated as a percentage of the sale price or deal value. It shows up on both sides of a deal: as the way certain workers get paid (sales staff, real estate agents, insurance brokers, some financial advisors) and as the cost customers pay for those services. The core logic is the same in either direction. When a transaction closes, a slice of the money changes hands as compensation for making it happen.
How a Commission Works
The percentage model dominates. A real estate agent earns a percentage of the home’s sale price. A salesperson might take 10% of the gross profit on a product. Some industries pay flat-fee commissions instead, a set dollar amount per unit sold or policy written, but percentages are the default.
The arrangement aligns incentives. The earner makes more by closing bigger deals, which is also what the employer or client wants. For whoever pays the commission, the cost is essentially self-funding, because payment only happens when revenue comes in. For the earner, income potential is uncapped, but so is the volatility. A slow month means a thin paycheck, and some of the financial risk that would normally sit with an employer shifts onto the worker.
Commission Structures for Sales Employees
Sales commission plans generally fall into three shapes, each balancing risk and reward differently.
- Straight commission. No base salary at all. Income comes entirely from sales. This is common among independent contractors and some real estate agents. The upside is large, and so is the downside during dry spells.
- Salary plus commission. A predictable base pay supplemented by a smaller commission percentage on sales. This hybrid is standard in B2B sales and higher-end retail, where deals take time to close.
- Tiered or accelerated commission. The commission rate increases after hitting defined targets. An agent might earn 5% on the first $100,000 in sales and 8% on everything beyond that. The structure rewards top performers disproportionately.
Employers sometimes use a “draw against commission” to smooth income for straight-commission workers. The employer advances a set amount each pay period, then deducts it from future commissions. Department of Labor rules allow this as an advance on wages, but if commissions never catch up, the employer generally cannot claw back the shortfall in a way that pushes effective pay below minimum wage. The draw has to be paid free and clear of that floor.
Overtime and Chargebacks
Commissions have to be factored into the “regular rate of pay” when an employer calculates overtime under the Fair Labor Standards Act. Total weekly compensation gets divided by hours worked, and overtime hours are paid at time-and-a-half of that blended rate. Section 7(i) of the FLSA carves out an exception for certain commission-paid retail or service workers, but only when specific conditions on commission share of pay and effective hourly rate are both met.
A chargeback happens when an employer takes back a commission already paid, usually because a customer canceled, returned the product, or defaulted. Whether that’s legal turns on whether the commission was “earned” or merely “advanced.” Advanced commissions can generally be recovered. Once a commission qualifies as earned wages under the plan in effect at the time, most states treat it like any other wage, meaning the employer can’t take it back without written consent. Several states require commission plans to be in writing and given to the employee.
Commission Fees You Pay for Financial Services
On the paying side, the biggest shift in the past decade has been in how brokerages charge for trades. Stockbrokers traditionally charged a per-trade commission, either a flat fee or a per-share rate, every time they executed an order. That model encouraged frequent trading and, at its worst, “churning,” where a broker trades excessively to generate fees rather than to help the client.
Today, most major brokerages have eliminated commissions on U.S.-listed stock and ETF trades. Charles Schwab, Fidelity, Vanguard, E-Trade, and Robinhood all offer zero-commission trading on those products. They still earn revenue elsewhere, including per-contract fees on options trades (commonly $0.50 to $0.65 per contract), advisory and management fees on robo-advisor accounts, and commissions on options, futures, certain mutual funds, and bonds.
Advisory Fees on Managed Assets
For ongoing investment management, the dominant model is an annual fee based on assets under management. The median AUM fee charged by human financial advisors sits around 1% per year, with a range from about 0.25% for robo-advisors up to 2% or more for specialized services. A $500,000 portfolio at 1% costs $5,000 per year, typically billed quarterly.
The AUM model discourages excessive trading but creates a different tension: the advisor earns more by gathering assets, not necessarily by managing them well. That fee also compounds over decades and can meaningfully erode long-term returns, which is why the value of active management should be weighed against the cost.
Insurance and Annuity Commissions
Financial professionals who sell insurance policies or annuities usually receive an upfront commission as a percentage of the premium or contract value. For annuities, that can run 5% to 7% of the contract value. The commission is built into the product’s pricing rather than billed separately, which makes it less visible to the buyer. Regulators have pushed for better disclosure partly for that reason. Broker-dealers and registered investment advisers must deliver a “relationship summary” (Form CRS) to retail investors that sets out fees, services, and conflicts of interest.
Real Estate Commissions After the NAR Settlement
Real estate commissions have gone through their biggest structural change in decades. For years, the standard total commission was roughly 6%, split between the listing agent and the buyer’s agent, with the seller paying both sides out of the sale proceeds. That’s no longer the default.
Following a landmark settlement by the National Association of Realtors in 2024, listing agents can no longer advertise offers of compensation to buyer’s agents through the MLS. Buyers must sign a written agreement with their agent before touring a home, and that agreement has to specify the exact compensation the agent will receive, not an open-ended range. It also must state that broker fees are “not set by law and are fully negotiable.” Buyers can still ask the seller to cover their agent’s fee, but it isn’t automatic.
Average total commissions have drifted to roughly 5% to 5.7%, with wider spreads than before. On a $500,000 home at 5%, that’s $25,000 rather than the $30,000 it would have been at the old 6% rate.
Taxes on Commission Income
How commission income is taxed depends on whether you’re a W-2 employee or an independent contractor.
If you earn commissions as an employee, your employer withholds federal income tax, Social Security, and Medicare from each payment. The IRS classifies commissions as “supplemental wages,” the same category as bonuses and overtime. Employers can either use a flat supplemental withholding rate or aggregate the commission with your regular wages and withhold based on your W-4. When supplemental wages exceed $1 million in a calendar year, the employer must withhold at the highest marginal rate on the excess.
Independent contractors, which includes many real estate and insurance agents, receive the full commission with no withholding. They owe income tax plus self-employment tax of 15.3%, covering both the employer and employee shares of Social Security (12.4%) and Medicare (2.9%). Quarterly estimated payments on Form 1040-ES are generally required if you’ll owe $1,000 or more after credits and withholding, and there’s an underpayment penalty for missing the safe harbor.
Negotiating the Rate
Commission rates are rarely fixed, whichever side of the table you’re on. Real estate agreements now have to disclose that fees are negotiable, which puts that on the table by design. Sellers with desirable, easy-to-market properties have the strongest position. Buyers can negotiate compensation in their written buyer agreement and can ask the seller to contribute as part of the purchase offer.
With financial advisors, AUM fees become more negotiable as a portfolio grows. Ask about published fee breakpoints where the rate drops at higher asset levels. Compare the total dollar cost too, because a flat-fee or hourly planner may deliver similar advice at a fraction of what a percentage fee produces on a large account.
In sales jobs, commission structures are often set by company policy, but experienced hires and top performers can sometimes negotiate a better split, a lower threshold for accelerators, or a larger guaranteed draw during ramp-up. Get the plan in writing before you start. Verbal promises about commission rates are hard to enforce and easy to change.
