What’s it called when you make money on the percentage of the total sales you make? It is called commission, specifically percentage commission or a sales commission. You earn a defined slice of each sale—say 5% of a USD 2,000 deal, or USD 100—rather than a fixed wage for hours worked. The percentage is usually written into a contract as the commission rate and applied to a base such as gross revenue, net revenue, or margin.

The anatomy of a commission

Commission is a contingent payment: the money moves only if a sale happens and usually only after defined conditions are met. The employer sets a rate, a base, and a trigger. The rate is the percentage. The base is what that percentage multiplies. The trigger is the event that makes the commission payable, such as a signed contract, a paid invoice, or cash collected.

The base matters as much as the rate. A 10% commission on gross revenue pays twice what a 10% commission on a 50% gross margin pays for the same sale. Companies that sell low-margin products often commission on margin to keep pay aligned with profit. Companies that sell high-margin services often commission on revenue because tracking cost per deal is messy.

Commission structures come in a few shapes. Straight commission pays only the percentage, with no salary. Salary-plus-commission blends a base with a variable rate. Draw against commission advances money the salesperson must repay from future commissions. Tiered or accelerative structures raise the rate as performance passes a threshold. Residual commission pays a recurring percentage on renewals or repeat purchases.

The economic logic is simple. Commission transfers part of the revenue risk to the seller and rewards output rather than attendance. That is why it dominates industries where individual effort maps cleanly to closed sales: real estate, insurance, car sales, staffing, advertising, and software.

How the percentage math actually works

A commission calculation has three inputs: sale value, commission rate, and adjustment rules. The arithmetic is multiplication, but the adjustment rules decide what gets multiplied. Splits, chargebacks, refunds, and quotas all move the base before the rate applies.

Take a USD 10,000 software sale at an 8% rate. Raw commission is USD 800. If the rep splits the deal 60/40 with a colleague, the rep earns USD 480. If the customer cancels within a clawback window, the company may recover part or all of that USD 480. If the rep is at 90% of quota, some plans pay the full rate only above 100% of quota, so the same sale can pay differently depending on timing.

Tiered plans are where most confusion lives. A common design pays 5% up to 100% of quota, then 8% above it. A rep who closes a USD 50,000 deal while sitting at 95% of quota might see part of that deal at 5% and part at 8%, depending on whether the plan applies the tier to cumulative attainment or to each deal. The two methods can produce materially different paychecks, so the plan document, not intuition, governs.

Clawbacks are the counterintuitive detail many people miss. Commission is often conditional money. If the customer refunds, defaults, or churns inside a defined window—often 30 to 90 days, sometimes longer for enterprise contracts—the employer can reverse the payment. A salesperson can therefore earn a commission, spend it, and later owe it back. This is legal in most US states when the written plan discloses it, though some states restrict deductions from wages.

Plain language: the percentage is easy, but the fine print decides what the percentage applies to and whether you keep it.

Quantified context: rates, ranges, and pay mix

Commission rates vary enormously by industry because profit margins, deal sizes, and sales cycles differ. Typical published ranges run from roughly 1% to 15% for straight percentage plans, with outlier structures above and below that band.

Industry Common commission rate Typical base Pay trigger
Residential real estate 5–6% total, split between agents Usually none Closing
Auto sales Flat dollar per unit or 1–3% of gross Small or none Vehicle delivery
Insurance (life/health) 20–50% of first-year premium Varies Policy issue
Software (SaaS) 8–12% of contract value Salary-heavy Signed contract
Staffing/recruiting 10–20% of placement fee Often salary Candidate placement
Advertising/media 5–15% of spend Salary-heavy Campaign booking
Retail sales 1–5% of sale Hourly wage Transaction

These are ranges, not rules. The same job title can carry very different plans across employers. A software sales rep at one company might earn 10% of contract value with a 50/50 salary-to-variable split; at another, 8% with a 70/30 split. The rate alone tells you little without the base, the quota, and the clawback terms.

Pay mix is the other number that matters. A 50/50 plan means half of target earnings come from salary and half from commission. A 70/30 plan leans toward stability. Straight commission is 0/100. Higher variable share usually means higher upside and higher income volatility. Salespeople comparing offers should compare total target compensation and the probability of hitting quota, not just the headline rate.

Edge cases and structures that change the answer

Not every percentage-of-sales payment is called commission. The label depends on who bears the risk and how the relationship is structured.

Affiliate marketing pays a percentage of referred sales, often called a referral fee or affiliate commission. The affiliate is not an employee and usually has no quota. The rate is typically lower, often 1–10%, because the affiliate does little beyond driving traffic.

Revenue sharing pays a percentage of revenue to a partner, franchisee, or investor. It can look identical to commission in arithmetic but differs legally and in risk allocation. A franchisee paying a percentage of sales to the franchisor is paying a royalty, not a commission.

Profit sharing pays a percentage of profit, not sales. The distinction matters when costs swing. A 5% profit share can pay zero in a loss year even when sales are strong.

Finder’s fees are one-time percentage or flat payments for introducing a deal. They are common in finance and professional services and are usually paid on a closed transaction.

Brokerage commissions, such as real estate or securities, follow regulated disclosure rules. Securities brokers in the US must disclose commission schedules under rules from the Securities and Exchange Commission and the Financial Industry Regulatory Authority. Real estate commission rates are negotiable and have been subject to antitrust scrutiny, including changes following the National Association of Realtors settlement announced in 2024 that altered how buyer-agent compensation is negotiated.

For employees, the legal classification matters. Under the Fair Labor Standards Act, commission can count toward minimum wage and overtime obligations for non-exempt workers, but only if the plan meets specific conditions. Employers cannot simply label a payment a commission to avoid wage rules. Misclassification disputes are common, and the written plan is the first thing regulators and courts examine.

Watch for a commission rate quoted without a stated base; it is not a complete term. Watch for clawback windows longer than 90 days with no cap on recovery. Watch for quota thresholds that reset the rate retroactively. Watch for plans that let the employer change the rate mid-period without notice. Watch for “draw” arrangements that create debt if sales fall short.

Common misconceptions

The biggest misconception is that commission equals a fixed percentage of whatever you sell. In practice, commission is a contract term with conditions. Rate, base, timing, splits, and clawbacks all modify the payout.

A second misconception is that a higher rate always means more money. A 15% rate on a tiny base with a brutal quota can pay less than a 7% rate on a large base with a realistic quota. Rate is one variable in a pay equation, not the answer.

A third misconception is that commission is always extra money on top of salary. In salary-plus-commission plans, the commission is part of target compensation, not a bonus above it. Employers set the salary lower because they expect the commission to fill the gap. If sales fall short, total pay falls.

A fourth is that commission is always paid at the moment of sale. Many plans pay on invoice, on collection, or on contract effective date. A sale that closes in December might pay in February. Cash-flow timing matters as much as rate for anyone living on variable income.

A fifth is that commission is a legal entitlement independent of the plan document. In most US employment settings, commission is governed by the written plan and state wage law. Disputes often turn on whether the plan was clear, whether it was disclosed, and whether the employer followed it. Verbal promises are harder to enforce than written terms.

Practical actions before you sign or set a plan

Whether you are evaluating a job offer or designing a compensation plan, a few concrete checks prevent most surprises.

First, get the plan document in writing and read the definitions. Identify the commission rate, the base, the trigger event, the payment date, and every deduction or clawback. If any term is vague, ask for a worked example with real numbers.

Second, calculate target compensation using realistic quota attainment. Multiply the rate by a typical deal size and a plausible number of deals per year. Compare the result to the salary and to market benchmarks. A plan that only pays well at 120% of quota is a plan that pays poorly for most people.

Third, model the downside. What happens at 70% of quota? At 50%? Does a draw create debt? Does a clawback erase a month’s pay? If the downside is unlivable, the upside is not the whole story.

Fourth, check state rules if you are an employee. Some states, including California, have specific rules about when commissions are earned and how they must be paid after termination. The US Department of Labor provides guidance on commission and wage payment under the FLSA, but state law often adds protections.

Fifth, if you are designing a plan, tie the rate to the metric you actually want to grow. Commission on revenue encourages revenue. Commission on margin encourages profitable deals. Commission on retention encourages durable customers. A plan that pays on the wrong metric will produce the wrong behavior, regardless of rate.

Sixth, document every change. Plans that shift mid-year without written notice are a common source of disputes and distrust. Clear, dated plan documents protect both sides.

Limitations and what commission does not tell you

Commission is a powerful incentive but a blunt one. It rewards measurable, attributable sales and tends to undervalue work that is hard to attribute: account management, customer success, team selling, and long-cycle relationship building. Companies that rely heavily on commission often need separate incentives for those roles.

Commission also creates risk for the seller. Income volatility is real, and clawbacks can convert earned money into owed money. Salespeople with high variable pay need emergency savings and a clear understanding of payment timing. Employers need clear, disclosed plans and fair dispute processes.

The rate itself is the least informative number in the plan. Base, quota, trigger, timing, and clawback terms determine actual pay more than the headline percentage. Anyone comparing offers or designing plans should compare total expected compensation and risk, not the rate in isolation.
