A commission is transaction-linked compensation in financial services: a payment to the selling firm and its representative that is triggered by, and usually sized as a percentage of, a customer's purchase. Unlike an advisory fee, which the client pays directly for advice or management, a commission is typically paid by the product's sponsor — the fund company, the insurer — out of the money the customer invests or the premiums they pay. That routing is what makes commissioned advice feel free at the point of sale, and it is also the structural conflict the industry's conduct rules exist to police: the recommendation and the paycheck point at the same product.
Commission
A commission is compensation paid to a financial salesperson or firm when a customer buys a product or executes a transaction — a sales load on a mutual fund, a payout on an annuity or insurance policy, a fee per trade. The advice attached to commissioned products is "free" because the product pays for it.

Quick Summary
- Commissions tie the professional's pay to the sale — the advisor earns when you buy, not when the advice works out.
- Common forms include mutual fund sales loads, insurance and annuity payouts, per-trade charges, and ongoing "trail" payments like 12b-1 fees.
- Commissions are legal and disclosed, but the disclosure lives in prospectuses and Form CRS documents most buyers never read.
- Regulation Best Interest requires brokers to consider costs and alternatives, mitigating — not removing — the incentive to recommend what pays.
- Fee-only advisors accept no commissions at all; advice-only planners additionally manage no assets, so the fee for advice is the entire revenue.

Advanced Explanation
Commissions come in more shapes than most buyers realize. Mutual fund A-shares carry front-end sales loads deducted from the amount invested; other share classes embed the charge in higher ongoing expenses or exit fees instead. Funds also pay ongoing 12b-1 fees out of fund assets — a trail that compensates the selling firm year after year for as long as the customer holds the fund. Insurance products are the deep end: commissions on permanent life insurance and annuities are paid by the insurer as a percentage of premium, can run to a large share of the first-year premium, and are invisible in the sense that no line item ever shows the customer what the seller earned. Bond sales by a dealer embed compensation in markups rather than itemized commissions.
The economic critique is not that commissioned salespeople are dishonest — it is selection pressure. When two adequate products sit on the shelf and one pays the seller more, the higher-paying one gets recommended more often, across thousands of advisors and millions of recommendations, even if every individual believes they are choosing on the merits. That pattern, documented for decades, is why the suitability standard was replaced by Regulation Best Interest for retail brokerage recommendations, why fee-only advisors advertise the absence of commissions as their defining feature, and why reading how a professional is paid tells you more than reading what they say about themselves.
Commissions are not automatically the expensive option, though. For a buy-and-hold investor making one purchase, a one-time commission can cost less over decades than an annual percentage-of-assets fee on the same money. The honest comparison is always total cost over the expected holding period, in dollars, under each model.
Used in a Sentence
“The annuity pitch never mentioned the word commission — Rosa only learned later that the insurer had paid the salesman a percentage of every dollar of her premium.”
How It Works
In a commissioned sale, the customer's money flows into the product, and the product's sponsor routes compensation back to the selling firm, which shares it with the representative under a payout schedule. Disclosure appears in the prospectus or policy illustration and the firm's Form CRS, and for brokerage recommendations, Regulation Best Interest requires a documented basis that the purchase serves the customer's best interest.
A hypothetical example across two structures: Alicia has $100,000 to invest. Option one is a mutual fund A-share with a 5% front-end load — $5,000 comes off the top, so $95,000 goes to work, and the fund's ongoing expenses continue from there. Option two is an advisor charging 1% of assets annually — nothing off the top, but roughly $1,000 in year one and every year after, growing with the account. Over one year, the load costs more; over twenty, the annual fee's cumulative cost can be several times larger. Neither structure is automatically better — the point is that the comparison must be run in dollars over your actual horizon, which almost no sales conversation volunteers. (Numbers hypothetical, for illustration.)
Pros and Cons
Pros
- No out-of-pocket fee at the point of sale, which suits buyers who would never pay separately for advice.
- For one-time, buy-and-hold purchases, a single commission can cost less over long horizons than years of asset-based fees.
- Commissions fund distribution of products — term life insurance is a clear example — that many households need but rarely seek out unprompted.
Cons
- The seller's incentive attaches to the sale, not the outcome — the defining conflict of interest in retail financial services.
- Costs are routed through the product (loads, trails, premium payouts), making them structurally hard for the buyer to see or compare.
- Products that pay the highest commissions — permanent life insurance, variable annuities — are disproportionately the ones that get oversold.
People Also Asked
Answers to the most frequently asked questions.
How do I find out what commission my advisor earned?
Ask directly, in writing — a professional with nothing to hide will answer in dollars. Documentation exists too: mutual fund loads and 12b-1 fees are in the prospectus fee table, brokerage compensation practices are described in the firm's Form CRS and Regulation Best Interest disclosures, and insurance commission structures, while hardest to see, can be requested from the agent. If the answer is evasive, that is itself information.
Are commissions bad?
Not inherently — they are a pricing model with a built-in conflict. A one-time commission on a product you hold for decades can be cheaper than years of advisory fees, and commissions fund the distribution of genuinely useful products. The problem is systematic: when pay depends on the sale, recommendations tilt toward what pays, which is why comparing what you were recommended against cheaper alternatives — or getting advice from someone with no stake in the answer — is worth the effort.
What does it mean that an advisor is "fee-only"?
Fee-only means the advisor's compensation comes entirely from fees clients pay directly — hourly, flat, retainer, or a percentage of assets — and never from commissions on products. It removes the product-sale conflict, though asset-based fee-only advisors still have an incentive to gather and retain assets. Advice-only planning is the narrower subset: fee-only and no asset management at all.
What is a trail commission?
An ongoing payment the product keeps making to the selling firm for as long as you hold it — the classic example is a mutual fund's 12b-1 fee, deducted from fund assets each year and shared with the distributor. Trails reward the original sale indefinitely, which is why a fund with a 12b-1 fee costs you more every year than an otherwise identical fund without one.
Have a question a definition can't answer?
Advice-only advisors answer questions like this for a transparent flat fee — no products, no commissions, no asset management.
