Commission is variable pay tied directly to sales performance, typically calculated as a percentage of the value of a sale. It exists to align a salesperson's incentives with the company's revenue goals — the more (or better) you sell, the more you earn. But 'a percentage of sales' can be structured in wildly different ways depending on the company, role, and industry, and understanding those structures matters whether you're the one earning commission or the one designing the plan.

Calculate Commission NowThe Basic Commission Formula
Commission = Sale Amount × Commission RateExample: a rep closes a $12,000 deal at a 6% commission rate. Commission earned = $12,000 × 0.06 = $720.
Flat Rate Commission
The simplest structure applies one fixed percentage to every sale, regardless of size or type. It's easy to understand and calculate, but it doesn't reward pushing for larger deals any more than smaller ones on a proportional basis beyond the natural scaling of the percentage.
Tiered Commission
A tiered structure increases the commission rate as a rep hits higher sales thresholds within a period, rewarding overachievement more than proportionally. This is one of the most common structures in B2B sales because it creates a strong incentive to keep pushing past an initial quota rather than coasting once a baseline is met.
| Monthly Sales Tier | Commission Rate |
|---|---|
| $0 – $20,000 | 4% |
| $20,001 – $50,000 | 6% |
| $50,001 and above | 8% |
Example: a rep sells $65,000 in a month under this tiered structure. Like income tax brackets, each tier's rate applies only to the portion of sales within it: $20,000 × 0.04 = $800, plus $30,000 × 0.06 = $1,800, plus $15,000 × 0.08 = $1,200. Total commission = $800 + $1,800 + $1,200 = $3,800.
Pro Tip
Confirm whether your tiered plan applies the higher rate only to the incremental amount above each threshold (as in the example above) or retroactively to all sales once a threshold is crossed — both models exist, and they produce very different payouts at the same sales figure.
Draw Against Commission
A draw is an advance payment against future commission, common for new reps ramping up in a role before their pipeline produces steady deals. A 'recoverable draw' must eventually be earned back through commission; a 'non-recoverable draw' functions more like a guaranteed minimum that isn't clawed back even if commission falls short.
Amount Owed to Company = Draw Paid − Commission Earned (if commission is lower, recoverable draw only)Example: a rep receives a $3,000 recoverable draw for the month but only earns $2,200 in actual commission. The $800 shortfall typically carries forward against future commission earnings until recovered.
Split Commission
When more than one person contributes to closing a deal — an account executive and a sales development rep, for instance — commission is often split between them by an agreed percentage. A $10,000 commission split 70/30 pays $7,000 and $3,000 respectively.
Commission Accelerators
An accelerator temporarily boosts the commission rate once a rep exceeds a specific milestone, often quota attainment for a period, functioning similarly to a tier but usually framed as a bonus multiplier rather than a base structure. For example, a plan might pay standard rate up to 100% of quota, then 1.5x the standard rate on everything above it.
Base Salary Plus Commission
Many sales roles combine a fixed base salary with commission on top, balancing income stability with performance incentive. On-target earnings (OTE) is the combined total a rep can expect to earn if they hit their full quota — typically split into a base component and a variable (commission) component.
- 100% commission (no base): highest variability, often used for independent agents or high-ticket sales
- Base plus commission: most common structure, balances stability and incentive
- Salary with bonus (not true commission): fixed pay with a periodic performance bonus not directly tied to a percentage of sales
Worked Example: Full Monthly Payout
A rep has a $3,000 monthly base salary plus commission on a flat 5% rate. This month's sales: $40,000. Commission: $40,000 × 0.05 = $2,000. Total monthly pay: $3,000 + $2,000 = $5,000.
Pro Tip
Use a commission calculator to quickly model different structures — flat, tiered, with or without a draw — before signing an offer or designing a plan, since the same headline percentage can produce very different take-home pay depending on the structure behind it.
How Commission Is Taxed
Commission is generally treated as ordinary wage income rather than as a separate category of pay, which means it's typically subject to standard payroll withholding in the same way a salary is. In some payroll systems, commission paid as a lump sum alongside a regular paycheck may be withheld at a supplemental wage rate that differs from your usual paycheck withholding — often higher — which can make a commission-heavy paycheck look like it's taxed more aggressively than your salary alone. That withholding difference is usually reconciled at year-end filing rather than reflecting a genuinely higher tax rate on commission income itself, but it's worth understanding so a smaller-than-expected net commission payout doesn't come as a surprise on payday.
What a Written Commission Plan Document Should Specify
A commission plan that exists only as a verbal understanding or a single onboarding slide is a recipe for future disputes. A properly documented plan removes ambiguity for both the rep and the company by spelling out every mechanical detail in writing before the period it covers begins.
- The exact rate or tier structure, including whether tiers are marginal or retroactive
- What counts as a qualifying sale — bookings, invoiced revenue, or cash collected
- Payout timing — immediately on signing, on invoice, or on payment received
- Clawback conditions, including the specific window and triggering events
- How draws, if any, are structured and recovered
- What happens to unpaid or in-progress commission if a rep leaves the company
Worked Example: Tracking Commission Across a Full Quarter
Extending the tiered example from earlier in this guide, consider a rep working under the same three-tier structure (4% up to $20,000, 6% up to $50,000, 8% above that) across a full quarter rather than a single month. Month one: $38,000 in sales produces $20,000 × 0.04 + $18,000 × 0.06 = $800 + $1,080 = $1,880. Month two, a slower month: $22,000 in sales produces $20,000 × 0.04 + $2,000 × 0.06 = $800 + $120 = $920. Month three, a strong month: $71,000 in sales produces $20,000 × 0.04 + $30,000 × 0.06 + $21,000 × 0.08 = $800 + $1,800 + $1,680 = $4,280. Quarterly total commission: $1,880 + $920 + $4,280 = $7,080 across $131,000 in total quarterly sales — an effective blended rate of roughly 5.4%, higher than the base 4% tier but below the top 8% tier, since most months didn't fully reach the highest bracket.
How Commission Structures Typically Evolve With Seniority
An entry-level sales development rep and a senior enterprise account executive at the same company rarely operate under identical commission mechanics, even though both are nominally 'in sales.' Junior roles more often use simpler flat-rate or lightly tiered structures tied to smaller deal sizes and shorter sales cycles, while senior or enterprise roles frequently introduce multi-year contract value calculations, larger accelerators, and sometimes a blended rate that accounts for both new business and the ongoing health of a growing book of existing accounts. This progression usually reflects the underlying reality that senior reps manage fewer, larger, and more complex deals, where a simple percentage of a single transaction doesn't capture the full scope of what they're actually being compensated to manage over time.
Commission Compared to Equity as a Long-Term Incentive
Some sales roles, particularly at earlier-stage companies, supplement or partially replace commission with equity compensation layered on top of cash pay. Equity ties reward to overall company value creation over a longer horizon rather than to any single period's sales, which can align incentives differently than commission does — a rep motivated partly by equity may weigh long-term account health and company reputation more heavily than short-term deal volume, since their eventual payoff depends on the company's trajectory as a whole rather than this month's number. Neither approach is inherently superior; they simply reward different time horizons and should be evaluated together, not commission in isolation, when comparing total compensation across job offers.
Common Ways Commission Disputes Arise
Even well-designed plans occasionally produce disagreements, usually clustered around a small set of recurring scenarios: a deal that closes right at a period boundary, a customer who cancels shortly after commission was already paid, a split deal where credit allocation between two reps isn't clearly documented, or a territory change that leaves ambiguity about who originated a given account. Addressing these scenarios explicitly in the plan document before they occur — rather than resolving them case by case after a dispute arises — protects trust in the plan and reduces the time managers spend adjudicating individual disagreements after the fact.
Pro Tip
When comparing job offers with different commission structures, don't stop at comparing headline rates — build out a full quarterly or annual model using realistic sales assumptions for each offer, including any equity component, to see which one actually produces more total value under conditions you consider likely rather than best-case.
Commission and Team-Based Incentive Pools
Beyond individual commission, some organizations layer in a team-based incentive pool that pays out when the whole team collectively hits a target, on top of (not instead of) each rep's individual commission. This is common in sales organizations that want to encourage mentorship, deal support, and knowledge-sharing behaviors that a purely individual commission structure doesn't reward on its own — behaviors like a senior rep helping a junior colleague work through a tricky objection, which benefits the team's overall number without directly benefiting the senior rep's individual commission at all.
Example: a five-person team with a collective monthly target of $250,000 hits $280,000, triggering a $5,000 team bonus pool split evenly five ways ($1,000 each), on top of each individual's own commission calculated separately under the standard tiered structure. The team pool adds a modest but meaningful incentive to collaborate rather than compete purely against teammates for the same finite customer base, without diluting the core individual incentive that still drives the bulk of each rep's variable pay.
A Final Word on Commission Transparency
Ultimately, nearly every mistake, dispute, and misunderstanding covered across the different structures in this guide traces back to the same root cause: a lack of transparency somewhere in the process, whether that's an unclear formula, an undocumented clawback rule, or a rate change communicated poorly. A commission plan doesn't need to be simple to be trustworthy, though simplicity certainly helps — it needs to be transparent, consistently applied, and open to good-faith questions from the people earning under it. Reps who understand exactly how their pay is calculated, even under a fairly complex structure, tend to trust the system far more than reps working under a simpler plan they don't fully understand or don't trust will be honored as written.
