Sales Commission
What is sales commission?
Sales commission is the portion of a rep's pay that is earned by closing deals — almost always calculated as a percentage of the revenue or value of each sale. It is performance-based, so it rises and falls with results, in contrast to a fixed base salary. Commission is the core of variable compensation and the main way companies tie a rep's earnings directly to what they sell.
Because it is usually the largest and most visible part of a rep's pay, commission is where comp design gets most of its attention. The headline rate is only the starting point: how commission is structured — and the mechanics layered on top — determine what a plan actually rewards. This page is the plain-language definition; the sections below point to the specific structures and mechanics that build on it.
How commission is calculated
At its simplest, commission is a rate applied to a base amount — typically a percentage of the deal's revenue. A rep who closes a $50,000 deal at a 6% commission rate earns $3,000. Real plans add structure on top of that: tiered rates that rise with performance, accelerators above quota, floors below it, and clawbacks if a deal reverses. Because of all that, the effective rate a rep actually earns often differs from the headline rate.
Types of commission structure
"Commission" is one idea, but it can be organized many ways. The commission structure is the set of rules that decides how deals become pay, and the main options are:
Flat-rate:
Flat-rate commission applies one percentage to every sale — simple and predictable.
Tiered:
Tiered commission raises the rate across bands of performance, rewarding overperformance.
Gross-margin:
Gross-margin commission pays on profit rather than revenue, discouraging discounting.
What this means?
Commission is the mechanism that aligns a rep's pay with the company's revenue — which is exactly why it is worth getting right. The structure and rate together decide which deals a rep chases and how hard they push past quota. Set well, commission focuses the team on the right revenue; set carelessly, it rewards the wrong behavior or, just as damaging, gets miscalculated and erodes trust. The rest of this glossary's commission terms are really about the two questions this one raises: how should commission be structured, and how do you calculate it accurately?
How Visdum handles commission
Commission is simple to define and hard to run at scale, because every plan wraps the base rate in structure — tiers, accelerators, floors, splits, clawbacks — that has to be calculated correctly for every rep, every period. Visdum computes commission directly from live CRM data, applies whatever structure the plan uses, and shows each rep a statement where every dollar traces back to the deals behind it. That is what turns commission from a monthly spreadsheet scramble into a number reps trust and finance can reconcile.

Frequently asked questions
What is sales commission?
Sales commission is the portion of a rep's pay that is earned by closing deals, usually calculated as a percentage of the revenue or value of each sale. It is performance-based, so it rises and falls with results, unlike a fixed base salary. Commission is the core of most sales compensation plans and the main way companies tie a rep's earnings directly to what they sell.
How is sales commission calculated?
Commission is calculated by applying a commission rate to a base amount — typically a percentage of the deal's revenue. If a rep closes a $50,000 deal at a 6% commission rate, they earn $3,000. Real plans add structure on top: tiered rates, accelerators above quota, floors below it, and clawbacks if a deal reverses, so the effective rate often differs from the headline rate.
What is the difference between commission and bonus?
Commission is pay tied to a specific closed deal, usually a percentage of its value; a bonus is a broader, often discretionary reward not tied to one deal. Both are variable pay, but commission is earned by the transaction while a bonus is granted for hitting a goal or milestone. Many plans use both, with commission as the core and bonuses layered on.
What are the main types of commission?
The main commission structures are flat-rate, where every dollar earns the same percentage; tiered, where the rate rises across bands of performance; and gross-margin, where commission is based on profit rather than top-line revenue. Plans also vary by what triggers commission — bookings versus collections — and by mechanics like accelerators and floors that adjust the rate at different levels of attainment.
What is a typical sales commission rate?
A typical SaaS commission rate is often cited in the range of roughly 5% to 10% of revenue, but the right rate depends heavily on the deal size, the pay mix, and the role. Rather than fixate on the headline percentage, most teams work back from on-target earnings and quota to set a rate that produces the intended pay at expected attainment.
Why does commission matter in a comp plan?
Because commission is the mechanism that aligns a rep's pay with the company's revenue, it is usually the largest and most scrutinized part of the comp plan — and the hardest to calculate accurately across a team. Errors erode trust and create disputes, while a well-designed commission plan focuses reps on the right deals. Getting it right is central to both motivation and financial control.
