Choosing a sales commission model sounds simple until you start comparing what the different options actually control.
Should commission be a fixed percentage of every eligible sale? Should the rate increase after quota is reached? Should the calculation use revenue or gross margin? Should recurring revenue continue to generate commission over time?
These are different design decisions, and the terminology is often used loosely.
The terms commission model and sales commission structure are often used interchangeably, but it is useful to separate them.
A commission model describes the core approach used to turn performance into commission. A sales commission structure is broader. It also defines who participates, what counts, which rates and thresholds apply, how sales credit is allocated, when commission is earned, and how changes and exceptions are handled.
If you are designing the complete plan, start with our sales commission structure guide. This article focuses specifically on the most common sales commission models, their advantages and trade-offs, and when each may fit.
What is a sales commission model?
A sales commission model defines the basic logic used to calculate variable compensation from sales performance.
For example, a company might:
- pay 5% of every eligible sale
- increase the commission rate after a salesperson exceeds quota
- calculate commission from gross margin instead of revenue
- continue paying commission while recurring revenue remains active
Those approaches create very different incentives even if the salesperson has the same target compensation.
It is also important to recognise that commission models are not always mutually exclusive.
A plan might combine a quota-based model with tiered rates. A gross-margin basis could be combined with an accelerator above quota. A team sale might use split crediting before the commission model is applied.
The model is therefore one design layer, not the complete plan.
Common sales commission models compared
These models can also be combined with crediting rules, draws, accelerators, caps and other mechanics.
Flat-rate commission
A flat-rate commission model applies one percentage to the eligible commissionable amount.
For example:
Eligible sales: €100,000
Commission rate: 5%
Commission: €5,000
The calculation is straightforward:
Commission = Commissionable amount × Commission rate
Advantages
Flat-rate commission is easy to communicate, calculate and verify.
A salesperson generally knows what an additional sale is worth, and Finance or RevOps can reproduce the calculation without interpreting multiple tiers or thresholds.
That simplicity can be valuable when the sales motion itself is straightforward.
Trade-offs
A flat rate treats each additional unit of eligible performance in the same way.
That means the plan may provide relatively little additional incentive for moving from good performance to exceptional performance.
It can also become problematic when transactions with the same revenue have very different economics. A €100,000 deal sold at strong margin and a €100,000 heavily discounted deal could generate the same commission if revenue is the only commissionable basis.
When it may fit
Flat-rate commission can work well where:
- transactions are relatively similar
- margins do not vary significantly
- the business values simplicity
- the role has direct influence over the eligible sale
- there is little need for nonlinear incentives
The more exceptions and modifiers that are added, however, the less “flat” the model becomes.
Tiered commission
A tiered commission model changes the commission rate when performance moves through defined levels.
For example:
- 0–€100,000: 5%
- €100,001–€150,000: 7%
- Above €150,000: 9%
The important detail is how the tiers are applied.
Under a marginal tier model, each rate applies only to the performance inside that tier.
Under a retroactive model, crossing a threshold may cause a higher rate to apply to a larger portion of performance.
Those two approaches can produce materially different payouts from the same sales result.
Advantages
Tiered commission can create stronger incentives for higher performance.
It also lets a company shape the economics of the plan rather than paying the same marginal rate at every level.
Trade-offs
The plan becomes more sensitive to precise definitions.
Teams need to understand:
- where each tier starts
- whether rates apply marginally or retroactively
- what happens exactly at a threshold
- which period determines attainment
- how corrections affect tier placement
A plan that says only “7% after €100,000” is not sufficiently precise.
For a deeper worked example, see our guide to tiered commission structures.
Quota-based commission
A quota-based model links commission or variable earnings to performance against a defined target.
Instead of looking only at the absolute amount sold, the plan asks how much of the assigned quota the salesperson has achieved.
For example:
Quota: €500,000
Actual sales: €550,000
Attainment: 110%
The commission logic can then vary depending on attainment.
A salesperson might receive one rate below quota, another around target and an accelerator above 100%.
Advantages
Quota-based commission connects payout to an explicit performance expectation.
It can also make plans more comparable across territories or roles when absolute opportunity differs.
Trade-offs
The quality of the incentive depends heavily on the quality of the quota.
If one salesperson receives a realistic target while another receives a structurally unattainable one, identical plan mechanics can create very different incentives.
Quota changes during an active period also need clear effective dates and governance.
When it may fit
Quota-based models are common where:
- roles have defined targets
- management wants to distinguish target attainment from raw revenue
- territories or books of business differ
- upside above target is strategically important
The quota should therefore be treated as part of the compensation design, not merely as an input to the formula.
Gross-margin commission
A gross-margin commission model changes the commissionable basis.
Instead of paying commission on top-line revenue, the company calculates commission from an agreed measure of margin or profit contribution.
For example:
Revenue: €100,000
Eligible cost: €70,000
Gross margin: €30,000
Commission rate: 10%
Commission: €3,000
Advantages
Gross-margin commission can better reflect the economics of a transaction where discounts, delivery costs or product mix vary materially.
Two salespeople may each close €100,000 of revenue while creating very different gross profit for the company.
A margin-based model can make that difference relevant to compensation.
Trade-offs
The model depends on reliable cost information.
The company needs to define:
- which costs are included
- when the margin becomes final
- how estimated costs are treated
- what happens if costs change later
- whether the salesperson can meaningfully influence the margin measure
A model becomes difficult to trust if the commissionable margin cannot be explained consistently.
See our gross-margin commission guide for calculation examples and the operational impact of later cost changes.
Residual commission
Residual commission continues to reward a salesperson while eligible recurring revenue continues.
Instead of paying only when the original transaction closes, the salesperson may receive commission over a defined period or while the customer or contract remains active.
Advantages
Residual commission can create a stronger connection between compensation and recurring revenue.
Depending on the role and business model, it may support an incentive to win customers that continue generating value rather than rewarding only the initial booking.
Trade-offs
The longer the commission continues, the more questions the company needs to answer.
For example:
- How long does residual commission continue?
- What happens if the account changes owner?
- Does renewal require continued involvement from the original salesperson?
- What happens after upsells or contractions?
- Does the commission end if the employee changes role or leaves?
- Which revenue qualifies?
Without clear rules, residual commission can create long-term entitlement and ownership questions.
When it may fit
Residual commission can be relevant in recurring-revenue businesses, particularly where the salesperson has a meaningful role in creating revenue that persists over time. It should not automatically be used simply because the company has subscriptions.
The earning rule should reflect what the company actually wants to reward.
Not everything called a “commission model” is really the same type of decision
A lot of commission terminology gets grouped together under “commission structures.”
That can make plan design unnecessarily confusing.
Some concepts determine how commission is calculated. Others determine pay mix, sales credit, timing or what happens at particular levels of attainment.
Separating these decisions makes the plan easier to reason about.
Base salary plus commission vs commission-only is a pay-mix decision
A salesperson can receive:
- salary plus commission
- commission-only compensation
- another mix of fixed and variable pay
That does not by itself determine the commission model.
For example, someone with a base salary plus commission could still be paid using:
- flat-rate commission
- tiered commission
- quota-based commission
- gross-margin commission
The same is true for a commission-only role.
Pay mix answers:
How much compensation is fixed versus variable?
The commission model answers:
How is the variable commission calculated?
Those questions should be designed together, but they are not the same.
For roles with a defined target level of total earnings, the relationship between base salary and variable compensation also connects to on-target earnings (OTE).
Accelerators, decelerators and caps modify a commission model
An accelerator increases the payout rate after a defined level of performance.
A decelerator reduces the rate under defined conditions.
A cap places a maximum on commission earnings.
These mechanics can be applied to several different commission models.
For example, a quota-based plan might pay:
- 5% below 100% attainment
- 7% between 100% and 120%
- 10% above 120%
The higher rates are accelerators applied to the underlying model. Similarly, a company could apply a cap to a flat-rate or tiered model.
It is therefore more useful to treat these as plan modifiers rather than entirely separate commission models.
If you are evaluating this particular design decision, see our comparison of capped vs uncapped commission.
Draw against commission is a payment and ramp mechanism
A draw gives the salesperson an amount in advance of future commission earnings.
It is commonly discussed as a commission structure, but it solves a different problem.
A salesperson with a long ramp period may not generate enough commission immediately to produce the intended earnings level. A draw can bridge that period.
A draw may be:
Recoverable: future commission offsets the draw.
Non-recoverable: the draw provides temporary guaranteed compensation without creating a future repayment balance.
The rules need to be explicit.
A draw therefore affects the timing and risk of compensation, while the underlying commission may still be calculated using another model such as flat-rate or quota-based commission.
Split commission is primarily a crediting decision
When multiple people contribute to one sale, the first question is often not the commission rate.
It is:
Who gets credit for what?
Suppose a €100,000 transaction involves two salespeople.
The company could:
- divide one 5% commission pool 60/40
- divide the commissionable basis 60/40 and apply different individual rates
- give one seller the primary commission and another an independent overlay
Those approaches can create different total payouts even though they all involve the same transaction.
That is why sales credit, commissionable basis, division of a commission pool and overlay incentives should not be treated as interchangeable.
See our guide to split commissions and sales crediting for worked examples.
Sales commission models can be combined
In practice, many commission plans use more than one mechanism.
Consider a salesperson with:
- €500,000 annual quota
- commission calculated from eligible revenue
- 5% rate up to quota
- 7% between 100% and 120% attainment
- 10% above 120%
- defined split-credit rules for shared deals
That plan is simultaneously:
- quota-based
- tiered
- using accelerators
- subject to crediting rules
Calling it simply a “tiered commission model” would therefore describe only one part of the structure.
This is why it helps to design the plan in layers rather than trying to find one label that describes everything.
How to shortlist the right sales commission model
There is no universal model that is best for every sales organisation.
Start with the business decision the model needs to support.
If simplicity is the priority
A flat-rate model may be sufficient when the sales motion and transaction economics are relatively consistent.
Adding tiers, thresholds and exceptions without a clear purpose usually makes a plan harder to manage without making it better.
If overperformance should create disproportionately higher upside
Consider quota-based commission combined with tiers or accelerators.
The company should model the resulting payout economics at different attainment levels before finalising the rates.
If deal quality matters as much as sales volume
A gross-margin or other value-based commission basis may be more appropriate than top-line revenue.
The salesperson should still be able to understand and influence the measure.
If revenue persists over time
Residual commission may be relevant when the role genuinely contributes to creating recurring economic value.
Define duration and ownership rules before launch.
If several people contribute to revenue
Solve the sales-credit problem explicitly.
Do not expect the commission formula to resolve unclear ownership.
If new hires need income support during ramp
A draw can help address timing while the underlying commission model remains unchanged.
The company needs clear recoverability and transition rules.
Five questions to answer before choosing a model
Before selecting the model, ask:
- What behaviour or business outcome are we trying to reward?
- Which performance measure can the salesperson actually influence?
- How much complexity can employees, managers and Finance realistically understand and administer?
- How does payout change at low, target and high attainment?
- What happens when source data, ownership or the plan changes later?
The first three questions help choose the model.
The last two determine whether that model will remain manageable once it is operating in the real world.
Common mistakes when comparing commission models
Choosing complexity because it looks more sophisticated
A more complicated plan is not automatically a better plan.
Every additional threshold, modifier and exception creates another rule that needs to be understood, calculated, reviewed and maintained.
Complexity should earn its place.
Comparing rates without comparing the commissionable basis
A 10% commission rate is not necessarily more generous than 5%.
Ten percent of gross margin may produce less commission than five percent of revenue.
Always compare the complete calculation.
Treating quota as separate from compensation design
If commission changes based on quota attainment, quota design directly affects earnings.
The compensation model and quota-setting process therefore cannot be treated as completely independent.
Mixing pay mix, crediting and calculation mechanics
“Base plus commission,” “split commission” and “tiered commission” answer different questions.
Putting them all into one list of alternative structures can hide important design decisions.
Designing only for exactly 100% attainment
A plan should also be tested below and above target.
Model the payout at several scenarios, for example:
- 50%
- 80%
- 100%
- 120%
- 150%
That makes nonlinear payout behaviour much easier to see before the plan goes live.
From commission model to sales commission structure
Choosing the commission model is only one part of designing the plan.
The complete structure still needs to define:
- participants and eligibility
- performance measures
- commissionable basis
- quotas or targets
- rates
- tiers and thresholds
- accelerators or decelerators
- sales credit
- earning events
- effective dates
- payout timing
- exceptions
- review and approval
- changes and adjustments
That is the difference between selecting a model and building an operating compensation plan.
For the complete design process, see our sales commission structure guide.
How Bentega supports commission plans
Once the model and rules have been defined, they still need to operate across performance data, calculations, review and payouts.
Bentega is built to help teams manage incentive compensation in a governed workflow rather than relying on disconnected spreadsheets, files and handoffs. It supports plan setup, calculation logic, approval workflows, visibility and payout records across commissions and other forms of variable pay.
The goal is not to make the commission model more complicated.
It is to make the rules that have already been chosen easier to operate, explain and maintain as the business changes.
Turn the model into a complete commission plan
Choosing between flat-rate, tiered, quota-based or margin-based commission is only the beginning.
Use our sales commission structure guide to define the rest of the plan, or document the rules in our commission plan template before implementation.
