What Is a Sales Commission?

A sales commission is variable pay earned when a worker meets the sales conditions set out in a compensation plan. It may be added to a base salary or make up most or all of a worker’s earnings, depending on the role and plan. The plan defines which sales count, what amount is used in the calculation, and when commission is considered earned and paid. A completed deal does not necessarily mean the commission is immediately payable because payment may depend on delivery, customer payment, or other stated conditions. Knowing these terms helps workers understand expected earnings and helps employers reward the sales results they value.

How Is Sales Commission Calculated?

A common method is to multiply eligible sales revenue by the commission rate. For example, if a representative earns 6% on eligible revenue and closes three qualifying deals worth $8,000, $12,000, and $15,000, the eligible revenue totals $35,000.

$35,000 × 0.06 = $2,100

Under those assumptions, the representative earns $2,100 in commission. Commission may supplement a base salary or make up a larger share of pay. Salesforce’s sales commission guide describes the revenue-times-rate approach and explains how commissions can reward workers for meeting defined goals.

The written plan determines the actual calculation. It may exclude canceled orders, refunds, taxes, shipping costs, or discounts. It should also state whether the rate applies to gross revenue, net revenue, or revenue collected by the company. A stated rate alone is not enough if the worker and employer have different understandings of what amount qualifies.

What Are the Common Commission Structures?

Salary Plus Commission

The worker receives regular base pay along with commission on eligible sales. The base provides more predictable income, while commission rewards sales results. This structure can suit roles that include important work beyond immediate selling, such as account planning or relationship management.

Straight Commission

Under a straight-commission plan, earnings come primarily or entirely from commissions rather than a fixed base salary. The U.S. Department of Labor’s commission guidance explains that commissions may be paid instead of salary and that the Fair Labor Standards Act does not require employers to pay commissions. Because income can vary considerably, workers should review how the plan defines qualifying sales, earnings, and payment timing.

Flat Commission per Sale

A flat-rate plan pays a fixed amount for each qualifying sale. For example, a plan might pay $75 for every completed service contract regardless of its value. This structure is straightforward to track and can work when sales have similar value or when the employer wants to reward a particular action.

Percentage of Revenue

This structure pays a percentage of eligible revenue, so commission generally rises with the value of the sale. The plan needs to define eligible revenue and explain how adjustments such as discounts or refunds affect the calculation.

Tiered Commission

A tiered plan changes the commission rate after a salesperson reaches a specified sales level. The written terms should clarify whether the higher rate applies only to sales above the threshold or to all eligible sales once the threshold is reached. These approaches can produce substantially different earnings.

Why Do Employers Use Commission Plans?

Commission plans connect at least part of a worker’s pay to business results. Employers may set different rates for new products, higher-margin offerings, new customer accounts, longer contract terms, or strategic markets. In this way, a plan can direct attention toward particular goals rather than rewarding every sale in the same way.

Incentives work best when they encourage behavior that supports both sales and broader business priorities. A plan focused only on closing deals quickly may give workers less reason to consider customer fit or long-term value. Employers therefore need to select measures that reward desired outcomes while accounting for customer experience and the quality of the sale.

When Is a Commission Earned and Paid?

The date a commission is earned may differ from the date it is paid. A plan should identify the event that makes commission earned, such as a signed contract, delivered product, or paid invoice. Payment may then arrive on a later scheduled payroll date.

This distinction matters when a sale changes or falls through. A cancellation, returned product, or customer nonpayment may reduce or delay commission if the plan makes payment depend on that condition. Some plans pay commission before revenue is collected and adjust a later payment if the sale collapses. Others wait until the customer pays. The written plan should explain how these situations affect earnings and whether an adjustment can be made to future pay. Closing a deal alone does not establish that commission is immediately payable.

What Should a Commission Plan Explain?

A useful plan identifies which products, services, or sales actions qualify. It explains the commissionable amount and rate, including any tiers or caps. It also states when commission is earned and when it is paid, since those may be separate dates.

The plan should address what happens when a sale is canceled, refunded, changed, or not paid for. Workers should also know how to request a review of a calculation and who handles that request. Reviewing these terms before relying on projected commission can help prevent misunderstandings about expected earnings.
